Studies using swabs from coronavirus patients seem to contradict earlier findings from cell cultures which showed Omicon replicated faster than earlier variants. As Benjamin Meyer from the centre for Vaccinology at the University of Geneva, explains there may be other reasons why omicron is spreading faster not just how quickly it reproduces. Predicting how the pandemic will develop is not possible, however predicting what individual mutations in the virus may develop and the impact they might have individually and collectively is getting closer, Cyrus Maher and Amalio Telenti of the biotech company Vir, have developed a way to model potential future viral mutations which they hope will now be used by many scientists worldwide looking to understand the virus. There are concerns that other viruses may be on the rise, bird flu in particular, which as Nicola Lewis of the Royal Veterinary College explains is now spreading to part of the world where it is not usually seen, and infecting other animals as well as birds.
