Adherence to antiretroviral therapy among people living with HIV attending medication-assisted treatment clinics in Dar es Salaam, Tanzania: a cross-sectional study.

Introduction: the prevalence of human immunodeficiency virus (HIV) among people who inject drugs (PWIDs) in Tanzania is estimated at 35%, significantly surpassing the 4.6% HIV prevalence of the general population. People who inject drugs living with HIV have been reported to exhibit lower adherence to antiretroviral therapy (ART), leading to increased rates of mortality, morbidity, and HIV transmission. This study assessed adherence to ART and associated factors among PWIDs in Dar es Salaam. Methods: this cross-sectional study involved 277 PWIDs living with HIV who attended MAT clinics in Dar es Salaam from May to July 2022. Antiretroviral therapy adherence was assessed using a validated one-month self-recall medication adherence scale, and associated factors were obtained through a structured questionnaire. Statistical analyses included chi-square tests, Fisher exact tests, and log-binomial regression. Data were analyzed using STATA version 15, with a p-value of <0.05 considered statistically significant. Results: this study found that 83% of the study participants had a high level of adherence to ART. Additionally, the results revealed that PWIDS who consume alcohol were less likely to have high adherence to ART (aPR 0.820). On the other hand, higher odds of ART adherence were observed among participants who had family support (aPR 1.028) and those who had adequate knowledge of ART benefits (aPR 1.285). Conclusion: the government and development partners should implement novel interventions such as alcohol reduction programs, ART education, and expanded HIV community outreach services. These interventions have the potential to improve ART adherence and reduce HIV transmission among PWIDs.

Prevalence and risk factors of urogenital schistosomiasis among under-fives in Mtama District in the Lindi region of Tanzania.

INTRODUCTION: Despite the ongoing intervention for schistosomiasis control among school-age children in the Lindi region of Tanzania, urogenital schistosomiasis continues to be a public health problem, presumably because other at-risk populations are not covered in praziquantel deworming campaigns. Evidence shows that under-fives become infected in their early life hence the need to understand the disease profile and the risk factors for exposure to infection so as to plan effective control strategies in this group. This study examined the prevalence and risk factors of urogenital schistosomiasis among under-fives in the Mtama district, Lindi region of Tanzania. METHODOLOGY/PRINCIPAL FINDINGS: A quantitative community-based cross-sectional study was carried out among 770 participants (385 under-fives and their 385 parents/guardians) in the Mtama district to investigate the burden and the risk factors associated with S. haematobium infection. A single urine specimen was collected from the under-fives and tested for macro and microhaematuria, presence of S. haematobium ova, and intensity of infection. A structured questionnaire gathered on risk factors for S. haematobium exposure in under-fives from their parents/guardians. Data analysis was performed using descriptive statistics, chi-square test, and logistic regression. Prevalence of S. haematobium ova was 16.9%, and that of macro and microhaematuria was 6% and 17.9%, respectively. Of the 65 positive under-fives, 49 (75.4%) 95% CI 65.4-86.3 had a light infection intensity, and 16 (24.6%) 95% CI 13.7-35.5 had a heavy infection intensity. Among the assessed risk factors, the parents/guardians habit of visiting water bodies for domestic routines (AOR: 1.44, 95% CI: 1.13-1.74), especially the river (AOR: 6.00, 95% CI: 1.20-35.12), was found to be a significant risk factor for infection of S. haematobium in under-fives. CONCLUSION/SIGNIFICANCE: A moderate prevalence of S. haematobium was found among the under-fives conceivably with adverse health events. The infected under-fives could be a source of continuity for transmission in the community. An intervention that covers this group is necessary and should be complemented with regular screening, health education campaigns, and an adequate supply of safe water.

Persistence of Schistosoma haematobium transmission among school children and its implication for the control of urogenital schistosomiasis in Lindi, Tanzania.

BACKGROUND: Despite twelve rounds of school-based preventive chemotherapy for schistosomiasis in endemic areas of Tanzania such as Mtama district, Lindi: the burden of Schistosoma haematobium infection has remained highly conceivable due to re-infections. The factors associated with continuity of S.haematobium transmission in Mtama district, Lindi have not been fully established. This study investigated the burden and factors contributing to the ongoing transmission of S.haematobium infection in the endemic district of Mtama, Lindi. METHODS: A quantitative cross-sectional survey was carried out among 649 school-age children in the Mtama district to determine the burden and factors associated with continuity of S.haematobium infection transmission. A single urine specimen was obtained from each pupil and tested for macro- and microhaematuria, presence of S.haematobium ova, as well intensity of infection; this was complemented with a survey of Bulinus spp snail intermediate hosts and their infectivity. A structured questionnaire was employed to gather information on individual and environmental risk factors for S.haematobium transmission. Summary statistics were computed for individual variables; while a univariate and multivariate logistic regression analysis was performed to assess the association between risk factors with S.haematobium infection. RESULTS: Prevalence of S.haematobium infection by macro- and microhaematuria was 13.1% and 46.2% respectively. The prevalence of S.haematobium ova was 52.7%; intensity of infection was light in 53.1%, and heavy in 46.9%. Snail intermediate hosts were Bulinus globosus and B.nasutus, whose infectivity was 2.2% and 1.3%, respectively. Among the assessed risk factors, long residency (10-13 years) in the area was a significant risk factor for the continuity of S.haematobium transmission (AOR: 21.79, 95% CI: 1.37-346.4). CONCLUSIONS: The observed 52.7% prevalence of S.haematobium infection represents unacceptably high prevalence after 12 rounds of preventive chemotherapy. Therefore, an urgent need for the implementation of integrated multiple control interventions in the Mtama district; is considered to be imperative.

The improvement of functional handwashing facilities during COVID-19: the perspective of Tanzania.

Fighting against coronavirus disease-2019 (COVID-19) goes hand in hand with the provision of proper water, sanitation, and hygiene (WASH) services. In this case, proper handwashing with soap and water plays a major role in the prevention of COVID-19, since it helps to deactivate and remove virus particles from the hands. This letter points out the drivers for the improvement of functional handwashing facilities during the COVID-19 pandemic in Tanzania, whereby three out of every 20 non-functional handwashing facilities were improved to make them functional. The letter also provides several recommendations to maintain momentum for improving functional handwashing facilities.

Tailoring of the ongoing water, sanitation and hygiene interventions for prevention and control of COVID-19.

Water, sanitation, and hygiene (WASH) interventions remain to be important in the prevention of further spread of coronavirus disease-2019 (COVID-19). Basic hygiene interventions such as handwashing with water and soap (HWWS) when applied consistently will deactivate and remove the virus particles from the hands. Realizing the efforts that have been made by countries world over in controlling the COVID-19, this letter seeks to discuss how the available WASH services can be used in the fight against further spread of COVID-19. The letter highlights the challenges being faced by the current WASH services in middle- and low-income countries and suggests measures that can be employed to strengthen the WASH services in this period of the COVID-19 pandemic.
