All I know is that a lot of symptomatic cases aren't counted, since of all the cases I've heard of lately, non got any official tests. Just the home kit or nothing.

Our oldest relapsed. He went to school on Monday after staying home for a week. At noon the school called to come pick him up. He's been home since and even had a fever again today. He was doing much better but now sounds hoarse, long coughing fits and still sore throat. Our youngest is still going to school. At the bus stop I notice a lot of the older kids are missing. I guess younger kids recover faster than the 10-12 year olds.

Perhaps we have the same strain here as is currently going around the states

The coronavirus mutant that is now dominant in the United States is a member of the omicron family but scientists say it spreads faster than its Omicron predecessors, is adept at escaping immunity and might possibly cause more serious disease.

Why? Because it combines properties of both Omicron and Delta, the nation's dominant variant in the middle of last year.

A genetic trait that harkens back to the pandemic's past, known as a "Delta mutation," appears to allow the virus "to escape pre-existing immunity from vaccination and prior infection, especially if you were infected in the Omicron wave," said Dr. Wesley Long, a pathologist at Houston Methodist in Texas. That's because the original Omicron strain that swept the world didn't have the mutation.

The Omicron "subvariant" gaining ground in the U.S. -- known as BA.2.12.1 and responsible for 58% of U.S. COVID-19 cases last week -- isn't the only one affected by the Delta mutation. The genetic change is also present in the Omicron relatives that together dominate in South Africa, known as BA.4 and BA.5. Those have exactly the same mutation as Delta, while BA.2.12.1 has one that's nearly identical.

This genetic change is bad news for people who caught the original Omicron and thought that made them unlikely to get COVID-19 again soon. Although most people don't know for sure which variant caused their illness, the original Omicron caused a giant wave of cases late last year and early this year.

So yeah, now it is relevant which strain you were infected by

"The Omicron infection antibody does not appear to protect well against the subvariants compared to Delta," said Dr. Shan-Lu Liu, a study author who co-directs the viruses and emerging pathogens program at Ohio State.

But Liu said the level of protection a Delta infection provides depends partly on how long ago someone was ill. That's because immunity wanes over time.

People who got sick with Delta shouldn't think of themselves as invulnerable to the new subvariants, especially if they're unvaccinated, Long said. "I wouldn't say anyone is safe."

Keep the virus circulating, new strains pop up. The cycle continues.

I've been feeling very tired lately, soar as well. No idea whether my body is fighting off the virus or more likely just exhausted from all the stuff that's been going on. My wife is getting better, but it's up and down and going very slowly. Still no strength to get outside, couple trips to the living room / kitchen a day at most.
