Broome County, New York, where I live, finally managed to get into the low community risk category on the CDC’s COVID map late last week, after many months in the high category with a few weeks of medium thrown in.
This is long hoped for news, but it is likely only a very temporary lull.
We had been high for so long due to our lower level of up-to-date vaccination and the fact that an Omicron subvariant that became dominant originated in central New York.
Unfortunately, another Omicron subvariant BA.5, is making its way into our area. BA.5 is already the most dominant strain in the US and carries the dubious distinction of being more contagious than other forms of Omicron. It may also have a tendency to more often affect the lower part of the respiratory tract, although this is still being researched; Omicron in general has been more likely to remain in the upper respiratory tract. It also appear to more easily infect people who are up-to-date on vaccination and those who have already had Omicron, even if the prior infection was only a few weeks ago. It’s difficult, though, to tease out which effects in the population are from the variant itself and which are from decreasing immunity that occurs over time.
It is also unfortunate that repeat infections increase the post-infection risk of stroke, heart attack, and other serious illnesses and bring the risk of long COVID.
Even with BA.5, though, being vaccinated and boosted is helpful. It lowers rates of severe disease, hospitalization, and death. Pfizer and Moderna are each developing vaccines/boosters that are more effective against Omicron that will be available in the fall. Of course, masking, avoiding crowds, and other public health measures are also helpful if transmission is high in your area.
Remember: the pandemic is still with us. Another new variant is spreading in India and several other countries and could cause another global wave of infections if it can out-compete BA.5. Stay alert and do what you can to take care of yourself, your family, and your community.
I’ll be doing that here. Even though our current infection rate is low, it has begun to creep up. I’ll be watchful.
