If you live in areas where that virus is endemic, and go outside, there is a pretty high chance that you have come into contact with it. This means that almost all people who come into contact with it suffer no ill effects. There are a few possibilities, it is not well suited to infecting humans, it requires some sort of rare genetic mutation in victims to make them susceptible, meaning that only a tiny portion of the population would be at risk, or it only infects people with severely compromised immune systems. If there is a sudden uptick in cases (which there doesn't seem to be evidence for, given the very low number of cases), then that could be evidence for the last scenario. Where something has changed in people's immune systems making them more vulnerable to infection. The obvious candidate for that would be COVID jabs, given that they have been conclusively proven to impact the immune system and trigger autoimmune diseases and recurrent diseases like shingles.
