Spatial analysis of climatic factors and plasmodium falciparum malaria prevalence among children in Ghana.

Malaria is a major public health problem especially in Africa where 94% of global malaria cases occur. Malaria prevalence and mortalities are disproportionately higher among children. In 2019, children accounted for 67% of malaria deaths globally. Recently, climatic factors have been acknowledged to influence the number and severity of malaria cases. Plasmodium falciparum-the most deadly malaria parasite, accounts for more than 95% of malaria infections among children in Ghana. Using the 2017 Ghana Demographic Health Survey data, we examined the local variation in the prevalence and climatic determinants of child malaria. The findings showed that climatic factors such as temperature, rainfall aridity and Enhanced Vegetation Index are significantly and positively associated with Plasmodium falciparum malaria prevalence among children in Ghana. However, there are local variations in how these climatic factors affect child malaria prevalence. Plasmodium falciparum malaria prevalence was highest among children in the south western, north western and northern Ghana.

Evaluation of TB/HIV Collaborative Activities: The Case of South Tongu District, Ghana.

BACKGROUND: There is a complex interaction between infection with human immunodeficiency virus (HIV) and tuberculosis (TB) infection that results in a synergistic increase in their prevalence, morbidity, and mortality. In Ghana, 32% of TB cases were estimated to be coinfected with the human immunodeficiency virus and acquired immune deficiency syndrome (HIV/AIDS) epidemic HIV, with the highest number of coinfections in the Volta Region. This study assessed the extent of linkage between the TB and HIV collaborative activities in the South Tongu District of Ghana. METHOD: The study employed both qualitative and quantitative methods to assess the coverage of activities to reduce the burden of TB in people living with HIV and the coverage of activities to reduce the burden of HIV in TB patients and explored the barriers to collaborative activities from the providers' perspective. RESULTS: The study showed that 344 (94.8%) HIV-positive clients were screened for TB, of which 10 (8.5%) were bacteriologically confirmed. Among those positive for TB, 6 (60%) received cotrimoxazole preventive therapy (CPT) and antiretroviral therapy. Sixty-seven (93.1%) TB patients were screened for HIV. Of these, 28 (38.9%) were retropositive, among whom 14 (50%) received anti-TB treatment. However, there were no records of isoniazid preventive therapy (IPT) for these patients. Inadequately trained personnel leading to work overload, manual record-keeping, lack of staff motivation, and absence of "enablers" packages for patients were identified as barriers to TB/HIV collaboration. CONCLUSION: Overall, there was a moderate linkage between TB and HIV collaborative activities in the study setting. Notwithstanding, there exist some barriers that mitigate against the successful implementation of the collaborative process from the providers' perspective, hence we recommend for measures to ensure effective, efficient, and sustained integrated TB/HIV activities by addressing these barriers.
