For the first time in more than a year, we are feeling some hope – or at least cautious optimism – that the pandemic may begin to disappear. But experts want us to know that there is still a concern that new mutations in the virus could bring it back.even stronger.
A major concern at the moment is the Delta variant, a type of virus Highly infectious SARS-CoV-2, which was first identified in India in December last year. It then spread rapidly to India and then to Great Britain, which has led to one significant increase of number of infected AND deaths.
The first case with the Delta variant in the United States was diagnosed 2 months ago, and now the cases are multiplying rapidly. Inçi Jildirim, specialist of Pediatric Infectious Diseases at Yale University School of Medicine, is not surprised by it that is happening.
“All viruses evolve over time and undergo mutations over timethey spread and multiply, ”she says. But unique to Delta is the speed with which it is spreading, says F. Perry Wilson, an epidemiologist in Jeil.
As far as we know so far, people who have been vaccinated against coronavirus appear to be protected against the Delta variant. But whoever sees them vaccinated and that does not implement preventive measures, risks being infected by the new variant, doctors say. Here are the top 5 things you need to know about the Delta variant:
1. It is more infectious than other types of virus
The World Health Organization (WHO) has called the option “faster and stronger.” In mid-June, the US CDC labeled Delta “a troubling option.” “It is many dramatic how the rate of increase of cases will change “- says Wilson. Delta is spreading 50 percent faster than the Alpha variant, that it was 50 percent more contagious than the original SARS-CoV-2, making the new version 75 percent more infectious than the original, ”he said.
According to him, in a completely carefree environment, where no one is vaccinated or wears a mask, – it is estimated that the average person infected with the original type of coronavirus will infect 2.5 other people. “In the same environment, Delta will spread from one person to maybe 3.5 or 4 other people. “Because of math, it’s spreading exponentially and faster.”
2. Persons without vaccinated are at risk
There are currently a disproportionate number of homeless people in the US vaccinated in the Southern and Apa stateslincluding Alabama, Arkansas, Georgia, Mississippi, Missouri, and West Virginia, where vaccination rates are low (in some of these states, the number of cases is rising even as some other states are lifting restrictions, as cases are bien).
t worryA recent study from the UK found that children and adults under the age of 50 were 2.5 times more likely to be infected with the Delta variant, ”says Yildirim. And so far, no vaccine for children ages 5-12 has been approved in the US, although this country and a number of other countries have authorized the use of vaccines for adolescents.
3. Delta can cause local epidemic outbreaks
How many people will be affected by the Delta, and how quickly it will spread The answer may depend, in part, on where you live, and how many people in your city have been vaccinated, says Wilson. In some cases, a city with low rates of vaccination, but that is surrounded by areas with rates of high vaccination, may contain the virus within its limits and the result may be “hyperlocal epidemic outbreaks”.
“Under these conditions, the pandemic may look different from what we have seen before, where there were hotspots all over the country,” the expert added. So instead of a 3-4 year pandemic, now that more many people are vaccinated or immunized naturally (after being affected by the virus), an increase in cases will be neutralized in a shorter period of time.
4. There is still a lot to learn about this variant
While more research is needed, early information about the severity of this variant includes a study from Scotland, which showed that Delta was twice as likely as Alfa to cause hospitalization of individuals without vaccinated (vaccines reducesignificantly risk).
Another question, approxefears the way Delta affects the human body. “It seems that coughing and loss of smell are less common. Headache, sore throat, runny nose, and fever are also present in this variant based on the latest surveys in Britain- emphasizes Yildirim.
A study by the Institute of Public health in England, showed that at least two of the vaccines are effective against Delta. Vaccine Pfizer-BioNTech was 88 for percent effective against symptomatic disease and 96 for percent effective against hospitalization.
WHEREAS, the Oxford-AstraZeneca vaccine was 60 per percent effective against symptomatic disease and 93 for percent effective against hospitalization. Should to get vaccinated an extra dose to be protected by the Delta? Experts say it is too soon to give an accurate answer. “We need more data to determine the current rate of spread and the impact of this new variant,” said Yildirim.
5. Vaccination is the best protection against Delta
Doctors say the most important thing you can do to protect yourself from Delta is to get fully vaccinated. This mean that if you are taking a two-dose vaccine like Pfizer or Moderna, you should wait for the recommended 2-week period for the doses to give their full effect.
But regardless of whether you are vaccinated, it is also important to follow the CDC guidelines, that is available to both vaccinated and non-vaccinated people vaccinated. ”Like everything in life, this is an ongoing risk assessment. When the outside sun is strong, youput protective cream on the face.
If you are in a crowded gathering, potentially with unseen people vaccinated, put on your mask and keep social distance. “If you are not vaccinated, the best thing you can do is get vaccinated.” / bota.al
