Covid ‘Delata’ Variant Becomes Powerful

Day 438: Stay Safe Minnesota

The Alpha variant from Britain is reportedly becoming more dominant virus in the US since April and many parts of the World including UK.

In The New York times, Carl Zimmer writes that the Alpha variant first identified in UK has become most dominant virus in the US since it was identified. It has also spread to many other parts of the World. Citing a new study Zimmer writes that the Alpha variants learns to hides from the human immune system and its stealth may be part of its success.

Alpha’s swift success has left scientists wondering how the variant conquered the world. A new study points to one secret to its success: Alpha disables the first line of immune defense in our bodies, giving the variant more time to multiply.

Dr. Maudry Laurent-Rolle, a physician and virologist at the Yale School of Medicine (who was not involved in the new study) told the Times “It’s very impressive. Any successful virus has to get beyond that first defense system. The more successful it is at doing that, the better off the virus is.”

Recent Surge of Delta Variant

In The Washington Post, Adam Taylor writes that the ‘Delta’ variant first identified in India, is spreading rapidly in UK and other countries. With its dominance, the British Government still evaluating whether they can reopen the country by June 21, Writes Taylor.

I know that these restrictions have not been easy, and with our vaccination program moving at such pace, I am confident that one day soon freedom will return.

British Health Secretary reportedly informed the Parliament that “the delta variant (B. 1.617.2) was 40 percent more transmissible than the alpha variant, also known as B.1.1.7, which was first detected in Britain. Scientists are still studying the matter.”

Citing the World Health Organization (WHO) report, the Post writes “the delta variant had been confirmed in 62 countries. That includes the United States, where it made up 3 percent of coronavirus cases as of May 8, according to the Centers for Disease Control and Prevention.”

During a recent a White House Covid-19 briefing, Dr Anthony Fauci, Director of National Institute of Allergy and Infectious Diseases (NIAD) reportedly told that spread and dominance of the B.1.617.2 (Delta) variant – that is now dominant in the UK is a “powerful argument” for people to get two doses.

“Clearly now its transmissibility appears to be greater than the wild type. It may be associated with an increased disease severity, such as hospitalization risk compared to (the Alpha variant, B.1.1.7), and in lab tests associated with modest decreased neutralization by serum, from previously infected and vaccinated individuals compared to the Alpha,” Dr Fauci said.

This is a situation, the way it was in England where they had a B.1.1.7 dominant, and then the 617 took over. We cannot let that happen in the United States. it’s ‘such a powerful argument’ to get vaccinated. Particularly, if you had your first dose, make sure you get that second dose. And for those who have been not vaccinated yet, please get vaccinated.

“There is reduced vaccine effectiveness in the one dose. Three weeks after one dose, both vaccines, the (AstraZeneca) and the Pfizer/BioNtech, were only 33% effective against symptomatic disease from Delta,” said Dr Fauci during the briefing.

Coronavirus-19 vaccination watch

According to the US Centers for Disease Control and Prevention (CDC) COVID vaccination tracker page (as of June 8, 9 a.m.) 372,100,285 doses have been distributed and 303,923,667 doses administered. According MDH COVID-19 Response vaccine data (as of June 7) a total of 5,422,565 doses of Covid-19 (Pfizer & Moderna) vaccines have been administered in Minnesota. According to the MDH latest tally (as of June 9) the confirmed COVID-19 cases in Minnesota are 603,144 (out of 10,065,154 tested) with 7,477 deaths.
