UK Covid patient was positive for record 505 days: researchers
British researchers believe they have documented the longest-known Covid-19 infection, in a patient who tested positive for a total of 505 days before their death. The previous record for persistent infection -- rather than repeated bouts of Covid -- is thought to be 335 days, the team from King's College London and Guy's and St Thomas' NHS Foundation Trust said.

After Omicron, we could use a break. We may just get it
By month 25 of the Covid-19 pandemic, we all probably should have learned not to try to anticipate what the SARS-CoV-2 virus is going to do next. It has so consistently defied predictions.

Covid loses 90% of ability to infect within 20 minutes in air – study
Coronavirus loses 90% of its ability to infect us within 20 minutes of becoming airborne – with most of the loss occurring within the first five minutes, the world’s first simulations of how the virus survives in exhaled air suggest. The findings re-emphasise the importance of short-range Covid transmission, with physical distancing and mask-wearing likely to be the most effective means of preventing infection. Ventilation, though still worthwhile, is likely to have a lesser impact.

Woman’s own immune system has possibly cured her of HIV
A woman in Argentina has become only the second documented person whose own immune system may have cured her of HIV. Researchers have dubbed the 30-year-old mother, who was first diagnosed with HIV in 2013, the “Esperanza patient,” after the town in Argentina where she lives. In English, “esperanza” means “hope.”
