HIV transmissions into intervention communities from control communities in the Botswana/Ya Tsie trial were similar to the reverse at baseline, and 10 times more common post-baseline, concordant with a predicted benefit of a universal test-and-treat HIV prevention intervention.

Analysis of epidemiological data reveals that viral loads in newly HIV-1 infected individuals in Uganda have declined for two decades, and evolutionary modelling shows that attenuation of the virus explains this decline.

HIV co-infection does not affect Mycobacterium tuberculosis mutation rates and does not drive the emergence of antimicrobial resistance within patients in the largest outbreak of multidrug-resistant tuberculosis in Latin America to date.

A method to assess the risk of self-sustained HIV transmission in heterosexuals from phylogenetic and epidemiological data is developed and, when applied to the Swiss HIV epidemic, shows that this risk is negligibly small for Switzerland.

Beyond well-recognized individual-level risk factors, HIV and hepatitis C transmission among people who inject drugs are further impacted by social and spatial network composition, and spaces in particular may represent efficient means for disseminating interventions that diffuse through the network.

Genomic analyses provide new insights into natural history and pathogenesis of cytomegalovirus infection and suggest new testable hypotheses that could be important for the design and implementation of new vaccines.

Phylogenetic evidence suggests that the majority of HIV infections occurring in the UNAIDS Fast-track city Amsterdam continue to have an Amsterdam resident as source, indicating that the majority of HIV infections in Amsterdam could be prevented through city-level interventions.

Under conditions where the force of HIV infection per cell is high, partial attenuation of infection with inhibitors can increase the number of live infected cells and may paradoxically be beneficial for viral spread.

CLR01 is a small molecule that could be an effective topical microbicide to eliminate HIV (and other enveloped viruses), and to antagonize host-encoded amyloid fibrils that promote HIV infection.
