These new versions that keep appearing are called variants. Scientists name them using Greek names such as Alpha, Beta, Gamma, Delta and the latest version Omicron. The variants then make new versions of themselves called subvariants which include BA.4 and BA.5 and they are the most dominant variant today.
The symptoms include persistent cough, fatigue, runny nose, sore throat, and headache. You can buy home testing kits at most pharmacies.
