Just when you thought that this pandemic might soon be over, scientists have found the  BA.2 virus, another subvariant of the Omicron variant , which could well be a little more contagious and, this is the bad part, more virulent, perhaps in the range of the Delta variant.  Plus, vaccinations are not as effective, even though a booster helps to prevent a person from death even if infected.  Current tests seem not to work as well, and it is possible that this is something new and not directly related to Omicron.  It's too early to tell if all that is true, but be aware. Early signs hint that this  B.2, named the Stealth Subvariant, might be behind the sudden jump of new cases in Denmark.    Early this month  Denmark  decided that the risk of dying from COVID-19 had dropped to a safe level so even while new cases remained a concern, they removed all restrictions to return to normality.  No need for indoor masks, ignore vaccine passports and open up nightclubs.  Not smart: Yesterday,
