Variant BA2 prevents most new cases, CDC mask mandate extended – NBC New York

What you need to know

  • According to the CDC, the omicron variant, BA.2, now accounts for 84% of the COVID currently circulating in the New York area, compared to 39% two weeks ago. It is also the dominant strain in the US (72.2%)
  • New York’s daily average, meanwhile, has risen 39% from the rolling average in the previous four weeks, but COVID hospitalizations and deaths remain steadily declining as recovery continues.
  • Still, recent case increases are a fraction of what they were during Omicron’s rise and peak in January, which is why officials are pressing in the context when estimating numbers; The test also went up a bit again

The so-called “stealth” variant of the omicron BA.2, which is causing a new rise in local, national and foreign corona cases, now accounts for more than 92% of the viruses circulating in the New York area, a significantly higher incidence than its national one. Stocks rose significantly further in the past week, according to new CDC data.

It also drives the vast majority of new infections in New York, the data shows. And Manhattan’s broadcasting rate per 100,000 residents is the highest of any borough.

For the New York area of ​​the CDC, which for agency purposes includes New Jersey, Puerto Rico and the Virgin Islands along with Empire State, that number rose 92% from 84% last week and 52% two weeks earlier.

This represents only positive COVID samples that are genetically grouped to isolate variants, which means the actual prevalence will be much higher, experts say.

New York, for example, floored about 3.43% of all positive samples submitted to labs during the COVID epidemic, according to CDC data. This is a lower percentage of the share among some of the states in the highest volume throughout the crisis like California (5.79%) but higher than Florida (2.54%).


In New York City, Department of Health data puts BA.2 at 85 percent 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 known how many cases are attributed to BA.2. The municipality claims that 13% of all positive samples ran in the last week of the data, a slight decrease from the previous week but still on a high trend compared to the beginning of the year. It is not clear from the page of the Ministry of Health in the city how many were registered in the cumulative.

The country also intensively intensified its additional surveillance efforts before the omicron wave began late last year. The groundbreaking case rates in New York 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.

Nationally, less than half a percent of America’s nearly 80 million COVID cases to date have undergone a genomic sequence and become 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 official – but has not been scientifically linked to more severe cases or has been shown to be more resistant to vaccines up to this point. But without 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.

The daily average of the five quarters, meanwhile, has risen 38% from the rolling average of the previous four weeks, but reflects only an increase of 521 cases in total in terms of raw numbers. Hospitalizations and deaths of the corona virus continue to decline.

Rolling indices have fallen by 11% and 60% compared to averages in the previous four weeks, and while hospitalizations and deaths are known retarded factors, officials say they do not expect a sharp rise in serious cases.

Why not? Well, look at the raw numbers. A 60% decrease in deaths is the difference between five and two fatalities, and the difference in hospitalizations is three patients (25 vs. 28). Recent case records are significantly lower than they were just two months ago, for example. The rate of new cases rolling in the city per 100,000 people of 158.45 rose from 125.84 a week ago, but dropped 95% from 3,115.97 to 100,000 reported on 9 January.

Manhattan has seen the highest broadcast jumps in recent weeks, with the borough reporting an average case rolling per 100,000 residents, 87 percent higher than the city average and the highest of any of the five boroughs.

Manhattan is responsible for every detail of one of the top 10 targets in terms of a rolling positive percentage, according to the latest Department of Health, though Long Island City in Queens leads the bunch.

Again, the raw data tells a more complete picture. Targeting Long Island City with the highest rolling positivity rate in the city right now, this is an increase of 27 cases. In TriBeca, No. 2 in this index, there is a difference of 29 cases – and only 12 for 10004 of the financial district.

In the end, officials say that the dominance of BA.2 was expected and it is expected that another version of COVID will reach the Torah as well. This does not necessarily exacerbate community risk. In the city, the level of alert is still “low.” It’s not going down anymore.

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.

In light of the rises, the federations plan 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 counties still have low levels of transfer and hospitalizations, which means that 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.
