We tend to believe or want to believe that the horrible SARS Covid-19 crisis is completely behind us. However, science signals that we need to stay alert with respect to the mutations of the virus. International events like the Paris 2024 Olympics bring together athletes and spectators from all continents and some of them still seem to carry the virus with or without symptoms. A report in the LANCET Respiratory Health mentioned that dozens of athletes were tested positive for the virus and a largely unaccounted number of spectators had carried the virus FLiRT variants. As tracking is difficult with more or less absent testing strategies the tests rely on waste water analyses and reports from health care institutions. The Olympic Games are over but the virus still lives on and variants keep popping up. Games during the summer months should be much saver than winter games as the time spent outside is much longer. Traveling in crowded transport, however, remains a potential health hazard. Huge crowds at Olympics are inevitable. After all, birds of the same feather flock together.
