Agree GrannyGravy13! Look at the figures for COVID - dropping like a stone! It has become a super-infectious, but mild or symptomless cold, just like the other coronavirus infections which are endemic. This was always going to be the fate of COVID: to become endemic. Mutant strains can only compete against circulating ones if they are more infectious; to be more infectious the virus cannot make you very ill, or you will take to your bed and not mix with others. That is a dead end for a respiratory virus. Those who are immune-compromised e.g. having chemo will want to avoid it, but everyone else can be confident they are very unlikely to be very ill. Our immune systems are like orchestras with many different instruments, and they need to practise to be proficient, so get out there and give them a chance to do their thing! We deal with hundreds of thousands of potential pathogens every day and rarely become ill. However. as GG said - it's personal choice: if you have health anxiety you will stay in - don't condemn everyone else.
