A new COVID subvariant has emerged here in the United States. It is designated XBB.1.5 and is considered the most transmissible Omicron variant to date by the World Health Organization. It is also considered to be highly immune evasive, which means it is more likely to cause infection among those who have COVID antibodies, whether from vaccines or prior infection. However, the vaccines should still be effective in reducing hospitalization and death rates from infection.
XBB.1.5 is especially prevalent in the northeastern region of the US. It is powering the rise in regional cases accounting for 72.7% of cases in the past week. It is also likely the driver behind Broome County, New York, where I live, again moving into the CDC’s high community risk level classification. (That will mean mandatory masking at our concerts this weekend.)
The XBB.1.5 subvariant orignated in the US, but has spread to some other countries. Meanwhile, China is suffering through a huge infection wave, although there is no reliable official data on its extent.
In many places, especially in the Northern Hemisphere winter, there are also high rates of flu and RSV.
As always, I’ll repeat my advice. Vaccinate, if you are eligible and vaccines are available to you. In particular, if you are eligible for the bivalent COVID booster, get it as soon as possible because it is much more protective against all Omicron strains than the original formulation. If you are sick, get tested. If you contract COVID or flu, immediately contact a medical provider to see if you can take antiviral medication to cut down on symptom severity. When there is risk in your area, use a high-quality mask in indoor public spaces and avoid crowds. Increase ventilation and/or air filtration indoors. Wash hands frequently and avoid touching your face (more for flu/RSV prevention than for COVID). Try to eat and sleep well. Look out for one another.
We need to work together for this pandemic to end. We are all tired of COVID but we need to fight effectively and continuously. Ignoring the risk and letting the virus spread just gives it even more opportunity to mutate and develop more virulent strains. We are now in our fourth year of the COVID pandemic. Let’s work together to make it the last.

My son tested positive Tuesday but fortunately he had the bivalent booster back in September when it first came out. His doctor basically told him to ride it out. Maybe an age thing but antiviral wasn’t recommended even though he asked. His fever finally broke yesterday. He’s 90% back to normal but still quarantining.
I’m glad to hear that your son is improving. I know that sometimes they won’t give antivirals to people who are younger and don’t have complicating medical conditions, especially if the antivirals are in short supply. I’m sure the bivalent booster helped tamp down the worst risk. 90% back to normal in less than a week is pretty decent.
