There’s a ton going on in the world of public health. This week we’ll cover wildfire smoke in New York, an emerging Covid variant, updates to Covid vaccine eligibility, diabetes in New Yorkers, and an advisory on local fish consumption.
Wildfire smoke in New York
Smoke from wildfires in Canada has made its way down to New York and surrounding states.
Poor air quality from wildfire smoke poses health risks to everyone, but some groups are especially sensitive:
- Older adults
- Pregnant women
- Children
- People with pre-existing respiratory and heart conditions
Air quality is measured by sensors that detect the concentration of pollutants in the air. Results are reported as the Air Quality Index, which is a number between 0 and 500. The higher the AQI, the more polluted the air is, and the higher the health risk. When the AQI exceeds 50 (the yellow category), people who are more sensitive to poor air quality should reduce strenuous activity outdoors (like working out). Once the AQI tops 100 (the orange category), everyone should reduce strenuous activity outdoors.
You can easily check the air quality of your local area on some weather apps, like AirNow, or download the EPA’s AirNow mobile app. And for a deeper dive on wildfire smoke, check out our post from last year.
New Covid variant in NYC
A new Covid variant has been detected in international travelers who arrived to New York City airports this month, as well as other airports in the United States. The new variant, NB.1.8.1, is getting some attention because it’s the major variant associated with a surge in Covid cases in China.
The good news is that this variant doesn’t appear to be any more severe than other circulating variants — it’s not meaningfully better at evading the immune system. The reason China may be seeing more Covid cases is not entirely clear, but we do see that this variant grows faster than many other circulating variants in cell culture, meaning it may be more transmissible.
What does this mean for you?
In New York, and the rest of the United States, we can expect another Covid wave this summer, with things likely picking up in the next two to three weeks. We’ve had summer Covid waves the past four summers, so it’s expected at this point.
Wastewater data for New York City is delayed, with the most recent data available as of May 6. The most recent data show that Covid began increasing earlier in May, but it was still at low levels in New York City. I’ll be back with updates once we get more data.
Will the current vaccine be effective against this new strain?
We think so. The new NB.1.8.1 strain seems to evade antibodies similarly to the last two strains vaccines were developed for, JN.1 and KP.2, meaning that the current vaccine should offer protection against severe disease. If you are moderately or severely immunocompromised or over 65, and you got a Covid vaccine in the fall, you can talk to your doctor about getting a second dose. I got the fall vaccine last year, so personally, I am not going to get another shot until this fall. But, I will be paying close attention to the Covid data (and sharing it here) and will likely mask up on the train and in grocery stores once virus activity starts to pick up more.
Covid vaccines will still be available for kids and pregnant women in New York
In last week’s post, we covered new proposed guidelines for Covid vaccines that would make it harder for adults and kids without chronic conditions to get vaccinated if they want to. Late last week, the Centers for Disease Control and Prevention released recommendations based on the proposal…
