But how worried should we be, since many people in this state are already vaccinated or are in the qualifying phase? The truth is, it’s hard to tell, even to the experts.
For now, the best we can do is evaluate the data we have about the different formats. Here’s a quick look at what we know.
First of all, let’s look at the number of cases of the coronavirus associated with the strain in Massachusetts detected so far, the CDC and the state said 977 cases of the British variant, 82 of the Brazilian variant, and 12 cases of the South African variant. find That figure has been up since the state’s first lawsuit, a British variant, was announced on Jan. 17.
British variable sum is fourth highest in the United States, while Brazilian variable sum is second highest.
This is a zoning map from the state Department of Public Health where the case was found.
An important caveat: This data does not represent the number of instances of an intrinsic variable. The genome sequencing needed to find variables is only possible in a finite number of tests. SARS-CoV-2-positive And it doesn’t represent the number of … all cases that might be in circulation, ”the CDC said.
Next, let’s look at the proportions of the variables in states.Data from the CDC show that the British variables as of mid-March accounted for nearly a fifth of the cases in states, while the other two official variants are B.1.427 and B.1.427. B.1.429, or Californian breed, is the second. Most prevalent
Again, data from a limited number of tests comes with the caveat. The CDC notes that “the proportions of the variables do not represent the total number that may be circulating.”
Information from very different sources is another warning sign that the species lurk in Massachusetts. The Massachusetts Water Resources Agency found a British variant in wastewater at Deer Island Treatment Plant.
Cambridge Biobot Analytics, the company that tested MWRA, said the test could always pick up the coronavirus, regardless of the pattern, but the company recently announced it has added discriminant capabilities, especially when sampling is available. Get the British variant The variable detected date is displayed in green on the chart.
This focus on the British variant is understandable as it is so unique among the breeds. It is also 60 percent more contagious and 67 percent more deaths than the original coronavirus, according to the latest forecast.
Nationally, the CDC also reports a number of different cases by state, broken down by the three best-known concerns.
The same warnings about limited testing apply.
Using data gathered from genome sequencing tests, scientists at the Scripps Research Institute have computed national estimates of the proportion of coronavirus cases caused by concern and variables of interest, among them the category of probability. Less loop
The chart shows that various forms of concern were associated with about a third of the coronavirus cases today nationwide as of mid-March.
Efforts by the CDC to track the spread of the coronavirus strains emerged earlier this year. But they have improved dramatically in recent weeks and are expected to continue to improve mainly because of $ 1.75 billion for genome sequencing in the stimulus package.
Says Thomas Tsai, assistant professor at the Harvard TH Chan School of Public Health.
However, the general image that appears is clear. British, South African and Brazilian breeds are gaining popularity in the United States, highlighting the need for people to take ongoing precautions to prevent their spread, he said.
“The top line of text is quite consistent. There is an ever-increasing prevalence of worrying variables, and that indicates continued surveillance over the coming weeks, even if the vaccine launch is premature, ”Tsai said. Still not out of the forest “
