With the lifting of public health measures all over North America and Europe, some governments seem to believe the pandemic is over. Restaurants and theatres are operating at full capacity and without proof of vaccination. PCR testing has been scaled back or nearly eliminated. Masks are gone — even in crowded and poorly ventilated school classrooms.
This is despite many people continuing to be highly susceptible to the disease — especially as vaccine-derived and prior infection immunity starts to wane — booster campaigns stall and increasingly contagious variants keep emerging.
