Infection with Neisseria gonorrhoeae, the causative agent of gonorrhoea, causes significant morbidity worldwide and can have long-term impacts on reproductive health. The greatest global burden of gonorrhoea occurs in low- and middle-income settings. Global public health significance is increasing due to rising antimicrobial resistance (AMR), which threatens future gonorrhoea management.

Background: Female Condoms are 90-95% effective against HIV transmission when correctly and consistently used and are also cost-effective. In general, condoms prevent sexually transmitted infections (STIs) and unwanted pregnancies. Although the COVID-19 pandemic had the potential to undermine routine healthcare services delivery and utilisation, there is limited evidence about the pandemic's effect on Female Condom uptake in Gauteng, one of the hardest-hit provinces in South Africa.

Human Immunodeficiency Virus Type 1 (HIV) set-point viral load is a strong predictor of disease progression and transmission risk. A recent genome-wide association study in individuals of African ancestries identified a region on chromosome 1 significantly associated with decreased HIV set-point viral load. Knockout of the closest gene, CHD1L, enhanced HIV replication in vitro in myeloid cells.

Malaria mortality remains above 500 000 people annually, demonstrating the need for new and innovative control approaches. Using a genome-scale, functional screen of Plasmodium sexual replication, Sayers et al. identified over 300 genes essential for malaria transmission through the mosquito, providing many new candidates for drug and vaccine development.

Consider prescribing doxycycline as prophylaxis for bacterial sexually transmitted infections (STIs) in certain clinical scenarios. New data suggests that a one-time dose of 200 mg doxycycline taken within 72 hours of an unprotected sexual encounter may reduce transmission of syphilis, gonorrhea and chlamydia by a combined two thirds in a high-risk population.
