Covid-19 is a (probably) man made variant of the Corona Virus family that has been around since the 1930s. It may have been leaked too soon, as it is not a deadly virus in itself. It would have been better if they had waited to develop a more deadly variant if eugenics was the purpose behind its creation. On the other hand, if you wanted something that could be escalated into panic, and thus allow for the creation of mandatory vaccines, it is possibly ideal. If everybody was forced to have a synthetic immune system, then whole populations could be eradicated by targeted diseases, and even more wealth would flow to the Pharma companies.

You can counter this by refusing vaccination, and avoiding ultra-processed foods, seed oils, and refined sugar products and many other well publicised health damaging products, like pharmaceutical drugs and smoking.
