Article Synopsis
  • Pediatric diarrhea is a significant public health issue, prompting a study on caretakers' understanding of its causes, treatments, and risks in Tanzania's Korogwe and Handeni districts.
  • The qualitative research involved targeted sampling, with data collected through interviews and focus groups, and analyzed thematically.
  • Findings revealed that while caretakers generally knew the risks of diarrhea, many lacked knowledge about its causes and treatments, leading to negative attitudes and poor management practices; thus, health education initiatives are recommended to improve caretaker knowledge and behaviors.

Objective: Many children in sub-Saharan Africa die from infectious diseases like malaria, pneumonia, and diarrhoea that can be prevented by early diagnosis, effective and targeted treatment. This study aimed to gain insights into case management practices by parents before they present their children to hospital.

Methods: We conducted a cross-sectional study among 332 parents attending a district hospital with their under-fives symptomatic with fever and/or diarrhoea between November 2019 and July 2020 in rural Tanzania.

Background: Right through history, humans have relied heavily on plants for sustenance and the healing of different ailments. One of the long-standing traditions that communities have inherited from earlier generations is the use of herbal medicines for the treatment of paediatric ailments, including diarrhoea. This study showcased medicinal plants used by traditional healers for the treatment of diarrhoeal diseases among under-five children in North-eastern Tanzania.

Article Synopsis
  • Malaria remains a significant public health issue in Tanzania, with over 93% of the population still at risk, despite a decline in cases over the past two decades; understanding community knowledge, attitudes, and practices (KAP) could improve control efforts.
  • This study utilized qualitative methods, including interviews and focus group discussions across 16 villages in high transmission areas, to assess community and health service providers' KAP regarding malaria.
  • Findings revealed that while many participants had good foundational knowledge of malaria, misconceptions about its causes and prevention methods—such as believing that it arises from bathing or drinking un-boiled water—hampered effective control, along with barriers like inadequate health resources and reliance on traditional remedies.

Background: The demand for herbal medicines continues to increase globally. However, community perceptions on their effectiveness and factors influencing their use have not been extensively investigated, notably in the Tanga Region, North-eastern Tanzania, where their use in treating various diseases, including paediatric diarrhoea, has flourished. According to studies, Tanga Region has a high prevalence of diarrhoea among under-five children.

Background: It has been more than 20 years since the malaria epidemiologic shift to school-aged children was noted. In the meantime, school-aged children (5-15 years) have become increasingly more vulnerable with asymptomatic malaria prevalence reaching up to 70%, making them reservoirs for subsequent transmission of malaria in the endemic communities. Intermittent Preventive Treatment of malaria in schoolchildren (IPTsc) has proven to be an effective tool to shrink this reservoir.

Background: African countries stand out globally as the region seemingly least affected by the COVID-19 pandemic, caused by the virus SARS-CoV-2. Besides a younger population and potential pre-existing immunity to a SARS-CoV-2-like virus, it has been hypothesized that co-infection or recent history of Plasmodium falciparum malaria may be protective of COVID-19 severity and mortality. The number of COVID-19 cases and deaths, however, may be vastly undercounted.

Background: Asymptomatic malaria infections largely remain undetected and act as a reservoir for continuous transmission. The study assessed the prevalence of submicroscopic asymptomatic malaria infections and anaemia in two rural low (300 m above sea level) and highland (700 m asl) settings of Korogwe District north-eastern Tanzania.

Methods: A cross-sectional malariometric survey involving individuals aged 0-19 years was conducted in June 2018 in the two rural villages.

Background: Results from a previous phase 3 study showed efficacy of the RTS,S/AS01 vaccine against severe and clinical malaria in children (in 11 sites in Africa) during a 3-4-year follow-up. We aimed to investigate malaria incidence up to 7 years postvaccination in three of the sites of the initial study.

Methods: In the initial phase 3 study, infants aged 6-12 weeks and children aged 5-17 months were randomly assigned (1:1:1) to receive four RTS,S/AS01 doses (four-dose group), three RTS,S/AS01 doses and a comparator dose (three-dose group), or four comparator doses (control group).

Background: Studies conducted thus far have demonstrated that the malaria vaccine (RTS,S) has a promising safety profile. Within the context of planning for future vaccine trials and for the purpose of building on previous research that has been undertaken in sub-Saharan Africa with regard to community perceptions about clinical studies, this research aimed to explore the community perceptions on the secondary health benefits established by the malaria vaccine trials (RTS,S Phase 2 and Phase 3) at the Korogwe site in Tanzania.

Methods: An exploratory qualitative study design was used.

Background: The candidate malaria vaccine RTS,S/AS01 reduced episodes of both clinical and severe malaria in children 5 to 17 months of age by approximately 50% in an ongoing phase 3 trial. We studied infants 6 to 12 weeks of age recruited for the same trial.

Methods: We administered RTS,S/AS01 or a comparator vaccine to 6537 infants who were 6 to 12 weeks of age at the time of the first vaccination in conjunction with Expanded Program on Immunization (EPI) vaccines in a three-dose monthly schedule.

Background: An ongoing phase 3 study of the efficacy, safety, and immunogenicity of candidate malaria vaccine RTS,S/AS01 is being conducted in seven African countries.

Methods: From March 2009 through January 2011, we enrolled 15,460 children in two age categories--6 to 12 weeks of age and 5 to 17 months of age--for vaccination with either RTS,S/AS01 or a non-malaria comparator vaccine. The primary end point of the analysis was vaccine efficacy against clinical malaria during the 12 months after vaccination in the first 6000 children 5 to 17 months of age at enrollment who received all three doses of vaccine according to protocol.
