HIV-1 evolved from SIV during cross-species transmission events, though viral genetic changes are not well understood. Here, we studied the evolution of SIVcpzLB715 into HIV-1 Group M using humanized mice. High viral loads, rapid CD4 T-cell decline, and non-synonymous substitutions were identified throughout the viral genome suggesting viral adaptation.

Background: Gay, bisexual, and other men who have sex with men (gbMSM) have a higher risk of human papillomavirus (HPV) infection and related diseases and would benefit from preventive measures such as HPV vaccination. We assessed the association between HPV vaccination and anal HPV infection in HIV-negative gbMSM and gbMSM living with HIV from the Lubricant Investigation in Men to Inhibit Transmission of HPV Infection study.
Methods: Participants attended 7 visits over 12 months where they provided a nurse-collected anal sample and self-completed a questionnaire on risk factors and HPV vaccination.

Bats are presumed reservoirs of diverse coronaviruses (CoVs) including progenitors of Severe Acute Respiratory Syndrome (SARS)-CoV and SARS-CoV-2, the causative agent of COVID-19. However, the evolution and diversification of these coronaviruses remains poorly understood. Here we use a Bayesian statistical framework and a large sequence data set from bat-CoVs (including 589 novel CoV sequences) in China to study their macroevolution, cross-species transmission and dispersal.

RNA viruses, especially those capable of cross-species transmission, pose a serious threat to human, animal, and environmental health, as exemplified by the 2024 outbreak of the highly pathogenic avian influenza H5N1 virus in cattle, unpasteurised milk, and workers on dairy farms in the USA. This escalating risk of a new RNA virus pandemic highlights the urgent need to implement One Health strategies. However, the centralised virus detection systems currently in use fall short of meeting the required level of virus surveillance and infection diagnosis, particularly in resource-limited regions.

Oral vaccination of wildlife against rabies via the distribution of vaccine-laden baits is used widely as a management tool in Europe and North America. Over the past several decades, successful programs have targeted important reservoirs, including coyotes, foxes, raccoon dogs, and raccoons, for prevention and control. However, other species (e.
