Near point-of-care HIV viral load testing: Cascade after high viral load in suburban Yangon, Myanmar

PLoS ONE, 2023
Introduction HIV viral load (VL) testing in resource-limited settings is often centralised, limiting access. In Myanmar, we assessed outcomes according to VL access and the VL cascade (case management after a first high VL result) before and after near ...

Higher viral load and infectivity increase risk of aerosol transmission for Delta and Omicron variants of SARS-CoV-2.

Swiss medical weekly, 2022
BACKGROUND Airborne transmission of SARS-CoV-2 is an important route of infection. For the wildtype (WT) only a small proportion of those infected emitted large quantities of the virus.
