At the heels of a tripledemic — this season’s collision of Covid-19, the flu, and respiratory syncytial virus (RSV) — comes the rise of invasive group strep A infection (or iGAS). Seen mostly among children, cases of the infectious disease are popping up all over Europe and in some states in the U.S. In the U.K., 21 children (aged 18 and younger) have died, along with 73 adults. In the U.S., where the first spike of invasive strep A was detected in November in Colorado, two children have died.
