- A WHO report stated that of the nearly 800,000 sequences collected in the past 60 days, 99.7% were Delta.
- Delta is highly contagious and has mutations that help it avoid immune responses.
- It was first discovered in India in October 2020 and has since spread to at least 166 countries.

Delta variants were detected in nearly 800,000 diagnostic tests, 99.7% of which were sequenced and uploaded to Central database In the past 60 days, the World Health Organization stated in a report Report on Tuesday.
Delta is highly infectious and can avoid immune response. First discovered in India in October 2020 The WHO said in the report that it has now spread to 166 countries.
According to the report, Delta’s spread in some countries in South America is “more gradual.” According to the report, Gamma, Lambda and Mu variants accounted for “a significant portion” of the country’s sequencing tests. The report found that globally, each of these three variants accounted for less than 0.1% of sequencing tests in the past 60 days.
But not every country has access to sequencing facilities, and WHO warns that the delay in uploading test results to the central database GISAID may mean that some variants are underestimated.
delta, It is a mutated version of the original coronavirus, with 152 offspring, According to Outbreak.info, It is run by Scripps and uses GISAID data. One offspring, AY.4.2, is being monitored most closely by public health agencies around the world, especially in the UK, where it is most often found.
Dr. Soumya Swaminathan, WHO Chief Scientist said On twitter on wednesday AY4.2 “may have some transmission advantages, need to be observed”.
However, it is not clear whether AY.4.2 is inherently more contagious, or whether other factors in England contributed to its spread. As of October 23, this variant accounted for approximately 11% of cases in the English Delta, and as of November 6 it accounted for approximately 15% of cases. According to the latest Public Health UK report Released on Friday.
So far, AY.4.2 does not seem to be more deadly than Delta, and the vaccine should prevent it. Public health report Established.
