Scientists Detect New MERS-Related Covid-Like Virus Spreading in Brazilian Bats

Scientists have discovered a new Covid-like virus named BRZ batCoV in moustached bats in Brazil, which contains a furin cleavage site that aids viral entry into human cells, similar to SARS-CoV-2, but is more closely related to the deadlier MERS virus. This virus has likely been spreading unnoticed for months, though there is currently no evidence it infects humans. Meanwhile, two new Covid variants, XFG (Stratus) and NB.1.8.1 (Nimbus), are spreading rapidly in the UK and Missouri, causing a rise in hospital admissions and symptoms like severe sore throats, although current vaccines remain effective. Health authorities are also concerned about an early and severe flu season, especially among children and young adults, which could strain healthcare systems alongside Covid. The presence of these evolving viruses highlights the importance of wildlife monitoring and vaccination efforts to mitigate potential zoonotic spillovers and respiratory illness impacts this winter. Additionally, a new flu strain detected in China raises pandemic concerns due to its possible animal-to-human transmission ability.
