Anyone who doubts covid restrictions, vaccinations, or masking SHOULD read this. Hospitals in California and elsewhere in the US are filling up again, in some places you may have to wait a day to get into the emergency room and tents are being set up in parking lots to hold the waiting patients. I have seen this personally. People are not only being infected with covid but othe respiratory viruses like RSV and ordinary flu. There is evidence that covid may weaken the immune system and increase the risk of infection by other respiratory diseases or perhaps other strains of covid. Avoid any risky activities, avoid crowds and gatherings.
