ABSTRACT

Background; Malaria prevalence continues to decline in Tanzania following the results of various intervention strategies which has lowered down the prevalence of malaria to less than 10%. However, the disease still poses a public health concern in the country. While symptomatic malaria can be diagnosed and treated, asymptomatic malaria infections become increasingly important for interrupting transmission. Following the decline of malaria in Tanzania, it is not known how much the epidemiology of asymptomatic malaria have changed in Dodoma Urban district particularly among primary school children. Therefore, this study was conducted to determine prevalence of asymptomatic malaria and use of different control measures among school children in Dodoma Urban district.

Objective: The study aimed to determine the prevalence of asymptomatic malaria and use of different control measures among of school children in Dodoma Urban district.

Methodology: A descriptive cross-sectional study was conducted using quantitative methods of data collection. A simple random sampling method was used to obtain 104 school children required for this study. Finger prick blood sample was collected for detection of malaria parasite, this was complimented with questionnaire that was used to determine the risk factors of asymptomatic malaria and the use of different control methods among school children. Data was entered into SPSS software version 20 to obtain frequency and their 95% Confidence interval and significance of 0.03%.

Results: A total of 104 primary school children aged between 6-13years (mean age =11.19years) were recruited and screened for parasitaemia using the mRDT and the overall prevalence of malaria was 1.9% for mRDT. School aged children   were more affected than those aged. The proportion for ITNs used was 78.8% while that of Indoor residual spray (IRS) was 82.7%.

Conclusion: Findings show the existence of low prevalence of asymptomatic malaria among primary school children at Dodoma Urban district. Where majority of the children reported using IRS for malaria control. Therefore, extra push should be used to ensure effective malaria control measures are implemented by the authorities to reduce burden of the disease among school-aged children and hence ensure public health in general by completely eradicating Malaria.


 


CHAPTER ONE

1.0 INTRODUCTION

1.1 BACKGROUND

Malaria is a disease of tropical and sub-tropical regions, which is transmitted by female anopheles mosquito vector. It is caused by Plasmodium falciparum, Plasmodium malariae, Plasmodium vivax, Plasmodium knowlesi, Plasmodium ovale curtisi and Plasmodium ovale wallikeri. Among the five species of Plasmodium;  Plasmodium vivax and Plasmodium falciparum are responsible for most malaria attributed morbidity(5).

Malaria can be of either symptomatic or asymptomatic. Asymptomatic malaria refers to the presence of malaria parasites in blood without any clinical symptoms usually asymptomatic individuals serve as the reservoir for transmission (1). Asymptomatic malaria can be analyzed  and detected by microscopy, rapid diagnostic test and molecular methods (5). For the case of symptomatic malaria; infection is accompanied by fever, chills, headache, nausea, vomiting, diarrhea, and extreme weakness and muscles aches (1). Whether its asymptomatic or symptomatic malaria, Plasmodium falciparum accounts for most malaria morbidity and  mortality which mainly occur in children under the age of 5years  in sub-Saharan Africa (5).

Plasmodium species have complex life cycle that involves transmission between an infected female anopheles mosquito vector and human host. The life cycle starts when a malaria infected mosquito inoculates sporozoites into the human host, these sporozoites invade the liver cells which mature and finally releases merozoites, then relapses by invading the bloodstream after weeks or even years letter the parasite undergo multiplication in the erythrocytes. Merozoites infect red blood cells while some parasites differentiate into sexual erythrocytic stage which are male and female gametes, both microgametes (male) and macro gametes (female) are ingested by mosquito during blood meal, then parasites multiply into mosquito’s stomach. Inoculation of the sporozoites into a new human host perpetuates the malaria life cycle (1). 

Malaria parasites can be identified by examining under microscope which is the gold standard for diagnosis. Other diagnostic techniques include rapid diagnostic test (RDTs) and Polymerase chain reaction (PCR)(6).

In Tanzania mainland’s national guidelines for diagnosis and treatment of malaria stipulate Artemether–lumefantrine (ALu) as the first line treatment for uncomplicated malaria in both adults and children (7).        

1.2 GLOBAL BURDEN OF MALARIA

In the past decades, intensive malaria interventions have resulted in a dramatic decline in global malaria morbidity and mortality (7). Between 2015 and 2018, only 31 countries were still malaria endemic. Due to this ongoing burden of malaria, the global technical strategy for malaria 2016 - 2030 was endorsed by World Health Assembly (WHA). The plan aimed for reduction of global incidences and mortality of malaria by at least 90% by 2030.

The WHO African region accounted for about 94% of malaria cases and death globally. Although there were fewer malaria cases in 2000(204million) than in 2019, incidence reduced from 363 to 225 cases per 1000 population at risk in this period. There is an increase in malaria cases total of 241 million malaria cases have been estimated and 627 000 deaths worldwide in 2020(8).This is a clear indication that malaria is still a problem and its still causing death worldwide.

  Asymptomatic malaria is prevalent in both low and high endemic regions. The asymptomatic carriers play important role as reservoirs for sustaining malaria transmission because they persist for long time and harbor gametocytes that are infections to anopheles mosquito (9).

1.3 BURDEN OF MALARIA IN TANZANIA

Tanzania has the third largest population at risk of malaria in Africa. Malaria is highest in the kagera region with prevalence of 8.8% on western shore of Lake Victoria and lowest in Arusha region which is less than 0.1 %(10). 

Malaria prevalence in Tanzania has decreased by half from 14.4% in 2016 to 7.3% in 2018 said by National Bureau of Statistics (NBS) the report also showed that new infections for children under the age 5 have dropped to 7.3% in 2017.

Furthermore, a cross sectional study was done to investigate the prevalence and correlates of asymptomatic Malaria and anemia among pregnant women in Southeast, Tanzania showed that the overall prevalence was 36.4%(11).This is a clear indication that asymptomatic malaria is still a burden especially in high transmission areas.

 In Dodoma Urban district where this study will be conducted, the prevalence of malaria is 2.5%(12). However not many studies have been done on the asymptomatic malaria. Therefore, this study aimed to determine the current prevalence of asymptomatic malaria and use of different control methods among of school children in Dodoma Urban district.

1.4   PROBLEM STATEMENT

Malaria is still a public health and life-threatening disease in Tanzania. The vulnerable group being infants, children under 5 years’ age, pregnancy women and patients with HIV/AIDS. School children are not included as the one of the vulnerable groups to malaria. However recent studies have showed that the burden of malaria has shifted from under 5 years age to children between 7 to 13 years(13)

A study was done to investigate the prevalence and correlates of asymptomatic Malaria and anemia among pregnant women in Southeast, Tanzania showed that the overall prevalence was 36.4%. This a clear indication that asymptomatic malaria is not only a risk for continued transmission, but also anemia in children and other health issues (11)

Another study was also done on asymptomatic malaria among school children in Morogoro Municipality showed that the prevalence of asymptomatic malaria was 5.4%((14). This clearly shows that the high prevalence is the problem because the asymptomatic carriers will serve as the reservoir for infection hence continual transmission of malaria. Also the asymptomatic carrier will pose a challenge in control and elimination of the malaria hence there is a need to conduct this study in order to investigate the risk factors that can lead to asymptomatic malaria. Therefore, this study was conducted to determine prevalence of asymptomatic malaria among school children in Dodoma Urban District.

 

 

1.5 RATIONALE

CHAPTER TWO

 

 LITERATURE REVIEW

Asymptomatic malaria refers to an individual who harbor malaria parasites such as Plasmodium falciparum but do not presents clinical symptoms of the disease (2). In malaria – endemic countries, a large proportion of P. falciparum are asymptomatic or sub- clinical (1). Asymptomatic carriers do not seek treatment for their infection, and therefore constitutes a reservoir parasite for newly hatched mosquitoes which then confer to transmission of the disease (3).

Patients with asymptomatic Plasmodium falciparum infection, especially children under five and school aged usually experience increase in morbidity due to anemia and reduced cognitive developments (4). The detection and treatment of asymptomatic carriers of Plasmodium parasites   is one of the innovative strategies for malaria control and it has been previously considered and included in the WHO guidelines for treatment of malaria (3). Distribution of malaria chemoprophylaxis to African school children is accompanied with lower rates of malaria parasitemia and severe anemia, few clinical attacks and reduced school absenteeism due to malaria (5).

PREVALENCE OF ASYMPTOMATIC MALARIA AMONG SCHOOL CHILDREN.

The prevalence of asymptomatic malaria varies in different regions around the global (1). A community study was conducted in Molyko, Cameroon among 116, 158 school children recruited in both urban and rural areas to determine the prevalence of asymptomatic malaria. The prevalence of asymptomatic malaria infection was 42.17% and 40.16%  in urban and rural areas respectively(15). This shows that there was lack of significant difference in prevalence between the two areas. School age children harbor malaria parasite of whether they are from rural or urban. Control measures are therefore, urgently needed to reduce the burden of the disease(15).  

 Also a study conducted in Ethiopia to determine the prevalence of asymptomatic malaria among school children and associated risk factors showed that out of 385 school children recruited, the prevalence was 22% % in both male and female(16). Furthermore, the prevalence of asymptomatic malaria decreased with the increase of age group.

A research study was also done in Morogoro Municipality, Tanzania, and the result indicated that among 317 school aged children the prevalence of asymptomatic malaria was 5.4%(14). This clearly indicates that school aged children are still at risk of being infected by malaria and their infection go unnoticed. Thus never getting treated resulting to further complications such as anemia.

2.3 KNOWLEDGE ON MALARIA AMONG SCHOOL CHILDREN

Several studies have been done to investigate level of knowledge on malaria, affordability and accessibility of ITN (3). Net ownership has also been related to education level of household members. Education attainment can have the impact on individual’s ability to understand the role of treated mosquito nets in malaria prevention (9).

Some survey reveals a lack of knowledge and many misconceptions about the transmission, treatment of malaria, control measures and antimalarial therapy as a knowledge gap could have an advance effect on school children who could be used as change agents and role models for their siblings and peers in malaria control strategy. Thus, there is a need to empower teachers with information about the cause of malaria and preventive strategies (9).  

False knowledge and misconceptions on causes of malaria will continue to increase the incidences and prevalence of malaria among schoolchildren since they are not able to implement correct preventive measures of malaria. Therefore, there is a need to make necessary changes in course based curriculum so that the school aged children will be able to assimilate correct causes of malaria (17).

However, a study performed in Morogoro Tanzania revealed that 99% (395) of the recruited children had knowledge on malaria transmission methods and used protective measures such as long clothes and ITNs, also mass media and teachers was the source of knowledge used in more than half of the recruited children. This tell us that knowledge of school children can be associated with the community surrounding them(14).

 

2.4 MALARIA PREVENTION METHODS FOR SCHOOL AGED CHILDREN.

The practice of malaria preventive measures has been related to the level of knowledge and belief of people. The understanding of the possible causes, mode of transmission and decision about the mode of adoption of preventive and control measures vary from community to community among individual households (10). The current emphasis on malaria control is centered on community-based strategies. In order to prepare for a successful malaria control program, it is necessary to evaluate the level of knowledge and practice of people living at risk area. (10). The majority of malaria cases are acquired via a bite from an infected mosquito, although some very rare cases are acquired trans-placentally or via transfusion of blood products (18).Generally, to avoid malaria infection, school age children must avoid being bitten by an infected mosquito. This can be accomplished by controlling physical environment, blocking mosquito access to the skin, repelling mosquito from skin(19).

Mosquito bites can be avoided by use of appropriate environmental control such as closing  doors and use of house with screened window and use of protective clothing that is skin should be covered with clothing (lightweight for comfort and light-colored to be less attractive to insects), sleeping children should be surrounded by nets, repellents, and insecticide(20).

Poor practice of malaria prevention may be linked to various factors as lack of follow up during sleeping time and parental beliefs that children are becoming older, the same authors argued that some children are usually sleeping in separate bedrooms from their parents which cause less usage of Insecticides Treated Nets(21).

Another study revealed that ITNs used for protection against mosquito bites have proven to be practical, highly effective and cost –effective intervention against malaria. A decline in malaria I sub-Saharan Africa is attributed to malaria control measures, predominately to the use of ITNs, IRS which have been implemented in high scale(14).

 

 

 

 

CHAPTER THREE

METHODOLOGY

STUDY AREA

The study area was in Dodoma Urban District. Dodoma urban district is one of the seven districts of Dodoma region of Tanzania. It is bordered to the North by Dodoma Rural District, to the East by Mpwapwa District, to the South by Iringa region and to the West by Singida region.

The climate of Dodoma Urban District is semi-arid, characterized by seasonal rainfall distribution with long dry and short wet seasons. There are seasonal rivers, shallow wells and dams in few villages. Dodoma municipality is administratively divided into one parliamentary constituency, 4 divisions, 41 wards, 18villages,170 streets and hamlets.

The malaria control initiatives that have been implemented in Dodoma includes providing citizens with Insecticide treated nets (ITNs), intermittent preventive treatment of Malaria in pregnant women (IPTp), Indoor residual spraying (IRS) and vector control.

 

STUDY DESIGN

To determine the prevalence of asymptomatic malaria among school aged children a descriptive crossectional study was conducted at Dodoma Urban District.

STUDY POPULATION

The study population was school aged children from the age of 6 to 13 years, were selected from which blood sample was collected by finger prick and taken for examining of asymptomatic malaria using Rapid Diagnostic Test (RDT)

SAMPLE SIZE ESTIMATION

The sample size was calculated from the below bio statistical formulae,

N=Z2 P (1-P)

£2

Where,

N=total number of subject requested in sample

Z=standard normal deviation value that correspond to a level of statistical significance P≤ 0.05 which is 1.96.

P=estimate of proportion of malaria prevalence among school age children in Dodoma which is 2.5% (12)

£ =Since P<20% which gives the marginal error of (3%)

 

N= 1.962× 0.025(1-0.025)/0.032

 

N=104.0433   

 

 The sample size for this study was 104 school age children

SAMPLING TECHNIQUE

The study used a simple random sampling technique to obtain a sample size required.

At first, a list of 41 wards was obtained with the assistance of DEO, and then two wards among of 41 was selected randomly.

Also, from the selected wards, a list of villages that are found within a selected ward was obtained. Followed by selecting randomly two villages, finally 2 schools were randomly selected within the two given villages.

With the help of the head teacher, students with the age of 6 to 13 years were selected randomly from each class to participate in the study. Then only the students that met all the inclusion criteria were taken to the next step. The selected schoolchildren were given an informed consent that was signed by their teacher. In the end, only the children who consented were recruited as part of the sample.

 ELIGIBILITY CRITERIA

 Inclusion criteria

The inclusion criteria were:

  • School children aged 6 to 13 years.
  • Children must be day scholar.
  • Teacher must sign the informed consent form for the child to participate in this study.
  • Children must be residents of that particular area.

 Exclusion criteria

The exclusion criteria were:

  • Sick children.
  • Children whose teachers refused to sign consent forms.
  • Children who will disagree to give blood sample.

 

 STUDY VARIABLES

 Independent variables

  • The independent variables were; Socio demographic characteristics such as level of education. Knowledge on causative agent, transmission, treatment, control and prevention of asymptomatic malaria.

 Dependent variables

The dependent variable was prevalence of asymptomatic malaria.

 DATA COLLECTION TECHNIQUE AND PROCEDURES

Structured interview using questionnaire

A questionnaire was prepared to collect information on demographic characteristics and assess knowledge and awareness on asymptomatic malaria and methods used in malaria prevention and control. The questionnaire consisted two versions, Swahili version which was used to collect demographic data and knowledge of malaria in primary school and English version, which was used to translate back Swahili data obtained from participants. A face to face interview approach was used and the responses obtained were filled to the questionnaire.

 

Data collection Procedures.

Blood samples obtained from school children were screened for Plasmodium parasite carriage using SD Bioline malaria Ag Pf/Pan (HRP-II/pLDH) Rapid Diagnostic Test (RDT). All necessary materials were gathered at the testing area which includes RDT kit (test cassette, buffer, and blood collecting device). Each s child was explained what the test is for and the procedures. Then the cassette was removed from the foil package and labeled with particular number (identification number). All these procedures were done while wearing gloves, the puncture site was disinfected (the fourth finger of non-dominant hand) with alcohol swab. Along that, a gentle prick was made toward the bull of the 4th finger and wipe off the first drop of blood with a dry cotton.

Using the blood pipette, 5micro liters of blood was collected then transferred to the cassette and then the buffer was added 3 to 4 drops and finally the cassette was placed for 15 minutes before interpretation of the results. The interpretation of the results was done as follow:

  • Negative-the presence of only control band indicates a negative result
  • Positive-the presence of both control and test band indicates the positive result
  • Invalid-if the test doesn’t show the control band even if there is the control band.

Then reporting was as RDT negative or RDT Positive or RDT invalid. Followed by discarding the cotton wool, RDT cassette and gloves into the box for infection waste

 

 DATA PROCESSING ANALYSIS.

Data collected was coded, entered, cleaned, and analyzed by using Statistical Package for Social Sciences (SPSS) version 20. Descriptive statistics was done to obtain the frequencies of variables of interest.

Objective 1: Prevalence of asymptomatic malaria was presented as overall prevalence, but also in frequency and proportion according social demographic characteristics.

Objective 2: Knowledge of each question is presented in frequency and proportional. Knowledge level is presented in frequency and proportion as high level knowledge, moderate level knowledge and low level knowledge. Then knowledge score scale was used whereby score was given to both correct and incorrect responses, a total of 12 questions were prepared and given to schoolchildren to answer them after a good instruction, and the correct score was given 1 and an incorrect score will be given 0 (22).Then scores will be categorized to the low, moderate and high level of knowledge as follows

  • 0-3 points =High level of knowledge
  • 4-7 points= Moderate level of knowledge
  • 8-12points= Low level of knowledge

 Finally, all the responses were added to find the mean score for all the recruited children.

Objective 3: Proportion of School children using different Malaria control measures were analyzed in both frequency and proportion.

 

 ETHICAL CONSIDERATIONS.

Before conducting the study, ethical consideration was requested from Muhimbili University of Health and Allied Sciences Institutional Review Board then permission to conduct this study in Dodoma Urban District was requested from the Regional Administration Officer, then to District Administration officer and other permission was requested from District Education Officer (DEO). Then the written consent forms was distributed to each participant in order to be given to their teacher and request them to read and sign if they allow their students to participate in this study.

 STUDY LIMITATION AND MITIGATION.

 Poor participation which was caused by some of the school age children refusing to answer the asked questions and was mitigated by explaining the advantages of the study to them.

 Response bias also occurred in this study and was mitigated by telling them to be truthful to all asked questions.

Also, recall bias was one of the limitations, which was mitigated by repetitively asking the same question to the same schoolchild and by giving enough time to remember.

Despite the general high level of knowledge score, there was still a big number of students 82(78.9%) who had misconception on malaria transmitting agent. About 93 (89.4%) students were aware that malaria is transmitted through mosquito biting however some other participants still mentioned other means such as drinking contaminated water 3(2.9%) and eating without washing hands 8(7.7%). Use of ITN and IRS were malaria preventive measure that primary school children mentioned, The majority being ITN 79(76%) followed by IRS 14(13.5%).

 The majority of the participants had proper knowledge on the health care seeking and taking medication ACTs 80(76.9%), instead of self-medication at home with traditional remedies.  Participants also mentioned, fever as a malaria symptom they knew was mostly mentioned symptom 90 (86%) followed by general body weakness 9 (8.7%)

CHAPTER FIVE

5.0 DISCUSSION, CONCLUSION AND RECOMMENDATIONS

5.1 DISCUSSION

This study assessed the prevalence of asymptomatic malaria and knowledge-based factors that determine the likelihood of malaria infection among primary school children aged 6 years to 13 years at, Dodoma urban district.

5.1.1 Prevalence of asymptomatic malaria

Malaria diagnostic methods using malaria rapid diagnostic test (mRDT) was used to detect malaria infection. Overall prevalence of asymptomatic malaria among primary school children was 1.9% for mRDT, which is lower compared to the study done in Bagamoyo, Kiwanga Pwani region in 2017 that reported prevalence of 14% by mRDT and 8% by LM(20).  It’s also lower compared to the study done in Morogoro in 2015 that reported prevalence of 5.4% by mRDT (21). Prevalence was lower than prevalence of asymptomatic malaria among school-aged children obtained from studies done in Northwest Ethiopia that reported prevalence of 6.8% (4), and Yemen that reported prevalence of 12.8%(16). This reflects low burden of the disease in the study area, which necessitates explicit shift in emphasis from control alone and includes a progression from control to elimination and eventual eradication through the appropriate actions to be taken by the authorities to intervene this problem, as these asymptomatic carrier acts as reservoir of the infection. 

Female children were found to have a higher prevalence than male children. Several studies also reported similar findings. Study done in Morogoro reported female children to be more infected than male children (21). However other studies reported different findings where male children were found with higher prevalence than female. Study done in Kenya to assess Prevalence and associated determinants of malaria parasites among Kenyan children, and study done in Rufiji district (22) reported the similar findings. So, there are variations in findings on the association between prevalence of malaria and the sex, more studies need to be done to come with general conclusion on this.


5.1.3 Knowledge on malaria preventive measures and use of different control measures.

Findings of this study revealed that, majority of the participants 78(75%) had high knowledge on the malaria preventive measures. Also, majority of participants (89.4%) mentioned mosquito as bitting as a method of malaria transmission, indicating the high knowledge of the relationship between malaria and mosquito. These finding are higher compared to study done in Western Ethiopia, which reported only 29.9%(24).

Our study found that 78.8% use of ITN as primary source for protection against malaria. These findings are supported by study done in Bagamoyo, which reported the same findings (17). This reflect the high knowledge on the malaria preventive measures, indicating that if efforts made to supply preventive measures they will be utilized properly.

Also, our study indicates that majority of primary school children in the study area have knowledge on symptoms of malaria, treatment seeking, ITN and IRS use. These finding are similar with study done in Bagamoyo(17). These findings are higher compared to study done in Western Ethiopia which, reported lower proportion(24).

The majority of the respondents (76.9%) reported to take ACT to treat malaria infection from healthcare. Study done in rural Geita district reported the same findings (21).

Better knowledge about malaria transmission and benefits of using available effective preventive and control measures by the individual households and the community could contribute much to the overall reduction of the malaria burden(24).

 

                                              


 

5.2 CONCLUSION

The findings from this study concluded that, prevalence of asymptomatic malaria among primary school children is low at Dodoma Urban district. The findings of this study indicated that primary school children at Dodoma urban district have high knowledge on malaria transmission, symptoms, and preventive measures. ITNs and IRS are still good choice for malaria preventions, the use of bed nets is widespread which makes its intensive use viable for malaria control. Although more education on the emphasis of using nets should be provided so as to increase number of people who use mosquito nets.

Also, there is need to have program for malaria screening among primary school children as intervention on malaria prevention and eradication in malaria at Dodoma Urban district.

Also due to lower asymptomatic malaria prevalence, there is need to initiate effective use of IRS program in the study area as one of preventive measure to reduce malaria incidences so as to ensure elimination of malaria.

 

 

5.3 RECOMMENDATIONS

1. There is need for a strong collaboration among major stakeholders including Government and non-government organization to mobilize and sensitize community on malaria as disease and develop effective method for prevention and control of the diseases.

2. As government implemented SST (Single Screening and Treatment) for pregnant women, it needs also to initiate the same approach to primary school children as these asymptomatic individuals become the great challenge toward malaria eradication because thy acts as reservoir of the infection.

3. Other studies need to be done in Dodoma Urban district to assess the burden of the disease on other groups especially secondary school students and community as well, as up to now the burden assess among primary school children and pregnant women only.

NAMBA YA UTAMBULISHO..................

 

Ridhaa ya kushiriki katika utafiti

Salamu! Jina langu ni Beatrice Thadeus Kulwa kutoka CHUO KIKUU CHA AFYA NA SAYANSI SHIRIKISHI MUHIMBILI (MUHAS), Mwanafunzi wa shahada ya kwanza ya sayansi ya maabara za binadamu. Ninafanya utafiti kwa madhumuni ya kuchunguza” Kuenea kwa malaria isiyo na dalili na matumizi ya hatua tofauti za udhibiti kati ya watoto wennye umri wa shule(miaka 6-13) katika wilaya ya Dodoma Mjini ,Tanzania. 

Kusudi la utafiti

Utafiti huu unakusudiwa kufahamu kiwango cha maambukizi  ya malaria isiyoonyesha dalili kwa watoto wa shule ya msingi, kukusanya taarifa juu ya sababu zinazopelekea kuongezeka kwa   malaria isiyo onyesha dalili za ugonjwa kati ya watoto wa umri wa shule ya msingi, kiwango cha maarifa ya watoto wa umri wa shule ya msingi juu ya ugonjwa wa malaria na kuweza kufahamu sehemu ya wanafunzi wanaotumia njia za kuzuia malaria.

 

Ushiriki utahusisha nini

Utafiti huo utahusisha watoto wa umri wa kwenda shule kuanzia miaka 6 hadi 14 ambao watalazimika kujibu maswali katika dodoso na kutoa sampuli ya damu ya kidole kwa ugonjwa wa malaria.

Usiri

Taarifa yoyote iliyokusanywa itaingizwa kwenye kinakilishi na nambari ya kitambulisho cha kusoma tu bila kuwashirikisha majina yao na mtu ambaye hajatambuliwa hataweza kupata tarifa iliyokusanywa.

Faida za kushiriki katika utafiti huo

Ikiwa unakubali mtoto wako kushiriki katika utafiti huu, atafaidika moja kwa moja au zisizo moja kwa moja. Moja kwa moja, mtoto yeyote atakayepatikana na ugonjwa wa malaria atapelekwa kwenye kituo cha afya cha karibu na shule kwa usimamizi.  Zisizo Moja kwa moja, tarifa zitakazopatikana ziitasaidia kuelewa ufahamu wa watoto juu ya udhibiti wa ugonjwa wa malaria na kiwango cha ugonjwa huu miongoni mwa watoto wa shule ya msingi wilayani Bagamoyo. Matokeo haya yatasaidia watunga sera kushughulikia tatizo hili.

Hatari zinazowezekana kutokea

Nakuhakikishia kwamba hakuna madhara yoyote yanayotarajiwa kutokea kwa mtoto wako kwa sababu ya kushiriki katika utafiti huu, pengine anaweza kuhisi maumivu kidogo tu kutokana na kuchoma kidole cha mkononi wakati wa kutoa damu.

Haki ya kujiondoa na mbadala

Ushiriki katika utafiti huu ni hiari yako kabisa. Unaweza kusimamisha Ushiriki wa mtoto wako kwenye utafiti huu wakati wowote hata ikiwa umeshampa idhini yako. Kukataa kuhusika au kujiondoa kwenye utafiti hautahusisha adhabu yoyote.
