The Omicron subvariant feeds most new infections, according to CDC – NBC New York

The COVID-19 subvariant estimated by New York State health officials is even more contagious than the first descendant of the potentially infectious omicron strain now accounts for up to 70% of all virus circulating in the Empire region. State, according to the news. CDC data was released Tuesday.

The prevalence of BA.2.12.1, which according to health officials appears to be up to 27% more contagious than BA.2 (which was also said to be more contagious than its predecessor, omicron), in the Nova region York’s agency has been The data show that it is growing at a much faster rate than nationally.

The CDC places it at around 62% of COVID cases in the New York region, which for its purposes also includes New Jersey, Puerto Rico and the British Virgin Islands, although it says the share of BA.2.12 cases .1 could be higher. In any case, this subvariant is the locally dominant strain, while the first variant of omicron, BA.2., Has maintained its national dominance in recent weeks (62% of cases compared to 36.5% of BA. 2.12.1).


The latest weekly update calculates the data as of April 30th.

Although so far no scientific evidence links BA.2.12.1 to more serious COVID-related diseases or to a reduced efficacy of the vaccine at this time, the increase in transmissibility seems clear. New York State, for example, represents the vast majority of the 56 U.S. counties designated by the CDC as having a high risk of COVID for the community.

None of the high-risk U.S. counties, according to the CDC, are in New York City, but all five districts appear to be experiencing some sort of drip effect.

The New York Department of Health variant crawler does not explicitly break down the BA.2.12.1 subvariant, but it does indicate an approximate split between omicron “non-BA.2” and omicron BA.2 in the current cases. The dominance of the latter seems to have begun to decline in early April, according to the latest count of variants in the city.

However, the proportion of genomically sequenced COVID-positive samples to isolate variants is a fraction of the total number of cases, which means that the prevalence of omicron subvariants is probably well-informed.

COVID reinfection rates across the state, both in terms of innovative cases and reinfections among those that have not been inoculated, have been rising every week since March 7, according to New York data. It is unclear, however, what is causing this.

“A significant spread of the community” of BA.2.12.1 was first observed in the central region of New York State last month, state health department officials said, and link the increase in infection rates to this specific omicron subvariant. COVID figures in downtown New York are now stabilizing, officials say, but other parts of the state appear to be experiencing similar, albeit smaller, associated viral increases.

New York City on Monday raised its COVID alert level by half, as cases exceeded a rate of 200 per 100,000 people in all five districts, health officials said. It was the first time the health department had adjusted to this level since it launched the new system under the administration of Mayor Eric Adams earlier this year.

Manhattan and Staten Island, respectively, have the highest transmission rates per 100,000 population, the latest health data show, but it is the first municipality to have a disproportionate impact on the city’s new case rate.

These two districts are also classified as “average” COVID alert counties by the CDC.

Here is the latest COVID alert level in New York.

No new COVID protocol will be implemented (or re-implemented) at this time, but if the alert level reaches a high level, the highest of the three set by health officials, the city will consider requiring face masks again. to all indoor public environments.

For now, New York Health Commissioner Dr. Ashwin Vasan says New Yorkers should be more careful than they have been in recent weeks, and is recommended for those at higher risk for serious illness. by COVID, for whatever reason, that they consider avoiding the crowd. indoor meetings and other high-risk situations.

The city continues to recommend that all New Yorkers, vaccinated or not, wear masks in indoor public settings, as highly contagious omicron subvariants continue to spread across the city, state, and much of the world.

While new case rates are rising, they remain well below what they were during the peak omicron rise in January. Most importantly, hospitalizations and deaths, the most important metrics from a public health perspective, continue to decline.

“The coming weeks will be critical to curb the spread of COVID-19 and return to a low-risk level so that we can enjoy our spring more safely,” New York Health Commissioner Dr. Ashwin Vasan said Monday. when announcing the alert level change. “And remember, the measures you take to protect yourself also protect others, especially the most vulnerable. As a city, we have the tools we need to fight this virus. As New Yorkers, we are together in this. By incorporating these steps. in our daily lives, we can continue to take care of each other and ourselves. ”
