Objectives: In Africa and Asia, 190 million preschoolers are vitamin A deficient. This study examined the social determinants of intake of vitamin A supplementation (VAS) among children aged 6-59 months during three different time periods in Kenya to identify those most vulnerable to vitamin A deficiency and highlight the varied targeting and outreach efforts; before the onset of a national restructuring and targeted distribution of VAS in children below 5 years through a twice-yearly door-to-door campaign called Child Health Weeks, during the implementation period, and several years later.
Methods: The cross-sectional, national Demographic and Health Surveys were administered in Kenya in 2003, 2008-09, and 2014.
Article Synopsis
- The study aimed to explore factors linked to undiagnosed diabetes in adults aged 35-64 in Namibia and South Africa, using data from recent health surveys.
- It utilized Andersen’s Behavioral Model to categorize factors into predisposing, enabling, and need factors, analyzing data separately for both countries through logistic regression.
- Key findings indicated that rural living and younger age were significant risk factors for undiagnosed diabetes in Namibia, while lower socioeconomic status posed a risk in South Africa; interestingly, higher blood pressure was linked to lower odds of undiagnosed diabetes in both countries.
The incidence and spread of dengue virus (DENV) have increased rapidly in recent decades. Dengue is underreported in Africa, but recent outbreaks and seroprevalence data suggest that DENV is widespread there. A lack of ongoing surveillance limits knowledge about its spatial reach and hinders disease control planning.

Arthropod-borne viruses are a major constituent of emerging infectious diseases worldwide, but limited data are available on the prevalence, distribution, and risk factors for transmission in Kenya and East Africa. In this study, we used 1,091 HIV-negative blood specimens from the 2007 Kenya AIDS Indicator Survey (KAIS 2007) to test for the presence of IgG antibodies to dengue virus (DENV), chikungunya virus (CHIKV) and Rift Valley fever virus (RVFV).The KAIS 2007 was a national population-based survey conducted by the Government of Kenya to provide comprehensive information needed to address the HIV/AIDS epidemic.
