BA2 Subvariants Fuel Community Spread – NBC New York

Two sub-variants of the high-transfer BA.2 Omicron strain feed “significant community spread” in parts of New York, state health officials say, calling their data the first to describe such sub-bullet transmission rates in the U.S.

The emergence of sub-variants BA.2.12 and BA.2.12.1 The two lineages of BA.2, a strain some of which have been described as the most contagious version of the corona virus to date, come when the parental sub-parent strengthens its already dominant grip in America and its sons. York, where data show it is moving faster than in the country.

New York State data puts the prevalence of BA.2 at 80.6% of COVID infections, although recently updated reports from the CDC suggest that its share may be even higher. And early findings suggest that sub-variations may be up to 27% higher than BA.2, which is said to be contagious up to 60% more than the original omicron strain that bypassed the world, leading to unprecedented case rates earlier this year.

Over the past few weeks, state health officials say they have focused on higher-than-average infection rates in central New York, and they believe the highly contagious sub-diversity is causing viral spread in this area.

During March, BA.2.12 and BA.2.12.1 rose and together contained more than 70% prevalence in central New York and more than 20% prevalence in the neighboring Finger Lakes region, the state said in a consultation released Wednesday.

Data for April indicate that levels in central New York are now over 90%. While evidence suggests that the region is struggling with the spread of the most widespread community associated with U.S. sub-diversity, health officials say there is no evidence of an increased disease severity associated with these strains. However, the data are constantly being evaluated.

As of Friday, Central New York holds the highest positive rates and cases per 100,000 residents out of every 10 New York areas, and it’s not even close. The rolling case rate in an area that includes the counties of Cayoga, Cortland, Madison, Onondaga and Osogo has a rolling positive rate of 12.4%, well above the closest (Finger Lakes, 9.5%) and dwarfs the rolling rate in New York City (3.1) percent.

The difference between the cases and 100,000 is even greater. Central New York ranks first on a rolling basis (53.6 new cases per 100K over a seven-day average), nearly double the state average (28.3) and the New York State average below 26.1.

Breakthrough infection rates have seen an increase in recent weeks, but it is not clear what (or what) is responsible. The increase may reflect a decrease in vaccine effectiveness among people who have not yet received reinforcement or some other reason. Most importantly, the age-appropriate vaccine efficacy rate in terms of new hospitalizations has not changed statistically significantly. See the chart below for details.


New cases and new hospitalizations with COVID-19 approved in the laboratory among fully vaccinated and unvaccinated adults, and estimated vaccine efficacy, from age 18 and up.

Here’s the latest NYS breakthrough data.


State re-infection data also puts the New York Central re-infection rate at a significantly higher level per 100,000 residents than the rest of the state. For now, hospitalizations are still manageable, though again, New York City’s rate of 100,000 (10.52) is well above the state average (5.53) and city (4.02).

In the end, officials say the dominance of BA.2 was expected and it is expected that variants and other sub-versions of COVID will also pass their turn. This does not necessarily exacerbate community risk. But you should keep track of the numbers.

“We are alerting the public to two Omicron sub-variants that have recently appeared and are spreading rapidly in upstate New York State so that New Yorkers can act quickly,” said State Health Commissioner Dr. T. T. Bast. News, the tools to fight them no. These tools will work if everyone uses them. “

New York State intensified its additional surveillance efforts before the Omicron wave began late last year, and so did the city, though some of the cases recorded to isolate versions remained part of the overall positive results.

According to the CDC, the state wanted about 3.43% of the cumulative samples since the onset of the plague, a higher rate than states with a large volume like Florida (2.54%) but lower than those like California (5.79%).

The so-called “stealth” variant of the BA.2 omicron, which is causing a new rise in coronary cases locally, nationally and abroad, now accounts for 84% of the viruses spread in the New York area. This is reported by Greg Kargol from NBC New York.

In New York City, Department of Health data puts BA.2 at 85% of the positive COVID samples tested, but that data is a week behind the data provided by the CDC. Officials say the omicron subdivision now makes up the majority of cases in the five boroughs.

It may never be possible to know how many cases are attributed to BA.2. The city claims that 14% of all positive samples ran in the last week of the data, quite similar to its highest weekly follow-up rate of 16%, recorded in late March.

It is not clear from the shelf of the Ministry of Health in the city how many samples were sequentially accumulated.

Nationally, less than half a percent of America’s nearly 80 million COVID cases to date have been genomically sequenced and made available to the public, according to CDC data, which probably reflects the exhaustive process involved in the work.

As of Tuesday’s update, BA.2 is about 86% of all national positive COVID samples in genomic sequence in the last two-week data period, up from 72.2% in the previous CDC weekly update and 35% in the previous two weeks. .

As a new sub-variant of the spread of the corona virus, Dr. Ayman al-Mohandes, dean of the New York University School of Public Health and Health Policy and a pediatrician and veteran academic, has the answers to all your leading questions. Hear from him about the second booster, Possible viral masking and surge related to BA.2.

It is said that BA.2 is inherently more transmitted than the original omicron strain – perhaps the most contagious form of the virus to date, according to a WHO source – but has not been scientifically linked to more severe cases or has been shown to be more resistant to vaccines up to this point. Warning, experts say.

Anecdotally, the reported symptoms are often particularly mild – like those common with an innocent cold that would not otherwise keep people away. However, in the case of BA.2, positive testing can take days, complicating matters for a city – and a country – that is eagerly trying to stand on its own two feet in the epidemic’s recovery effort.

And yet, with more holiday gatherings before the weekend for Easter and Passover, health officials at all levels of government are demanding increased caution.

The New York Department of Health, for example, has reminded people of its recommendation to wear a face mask indoors, especially in groups when the immune status of others is unclear. Also be checked before departure, say the city.

“Encourage your friends and loved ones you see this weekend to get tested before you even get together,” Health Commissioner Dr. Ashwin Wassen said. Call 311. The Department of Health wishes all New Yorkers happiness, together and good health. “

New York City Health Commissioner Dr. Ashwin and Essen say the city is more willing than ever to respond if COVID-19 cases rise again. NBC New York’s Andrew Siff reports.

At the national level, only 19 of America’s more than 3,200 counties are considered “high” at risk by the CDC, based on community-level monitoring recently introduced. More than 95 percent of U.S. counties, including all five in New York and all of the neighboring states of New Jersey and Connecticut, are also considered low-risk.

However, parts of central New York, such as Onondaga and Cayuga counties, are now in the high-risk area of ​​the CDC and some of the surrounding areas have recently turned yellow. The New York Department of Health announced Wednesday the emergence of new BA.2 sub-variants, which officials believe have driven the sharp rise in central New York and the surrounding areas.

March data in those areas show that the two sub-variations (BA.2.12 and BA.2.12.1) were more common in more than 70 percent of cases in central New York. In April, the rate rose to more than 90 percent of cases – making the findings the first reported cases of significant community outbreak caused by the new sub-variations in the U.S.

In light of the rises, the federal government plans to extend the mandate for the national travel mask in at least two weeks, sources with knowledge of the decision said Wednesday.

Although infections are rising, most districts still have low levels of transfer and hospitalizations, which means people living in these areas do not have to wear masks indoors under CDC public health guidelines.

Dr. Anthony Pauchi said this week COVID will continue to circulate in communities for the foreseeable future, and people will have to make their own decisions about the risk they are willing to take based on their age and health status.
