BACKGROUND Pretreatment drug resistance in people initiating or re-initiating antiretroviral therapy (ART) containing non-nucleoside reverse transcriptase inhibitors (NNRTIs) might compromise HIV control in low-income and middle-income countries (LMICs). We aimed to assess the scale of this problem and whether it is associated with the intiation or re-initiation of ART in people who have had pr...

To the Editor: Ehrlichia ruminantium, the causative agent of heartwater, is transmitted by Amblyomma spp. ticks. Amblyomma variegatum ticks, which are found in the Caribbean and sub-Saharan Africa, except in certain areas of southern Africa, are major vectors of E. ruminantium (1–3). A. lepidum is also an important vector of heartwater, especially in eastern Sudan (4). However, few epidemiologi...

Projections show that the effects of climate change in Africa will not be uniform over the region. The region is extremely vulnerable to the impact of climate change because of poverty, a high pre-existing disease burden, fragmented health services and existing water and food insecurity.

Regional differences in neurovirulence have been documented among subtype/clade-C HIV-1 isolates in India and Southern Africa. We previously demonstrated that a C31S substitution in Clade-C Tat dicysteine motif reduces monocyte recruitment, cytokine induction and direct neurotoxicity. Therefore, this polymorphism is considered to be a causative factor for these differences in neurovirulence. We...
