Just because your fast test has become a negative for Covid, don’t overlook symptoms such as sore throat and fever as a mild flu, warning epidemiology based in the US, Faheem Younus He further opines that you have to repeat the test in 24 to 48 hours, get the current PCR test. And also isolate for 5-10 days.
Don’t just believe one fast negative test, said Younus This happens when Omicron Subvarians BA.2, which is more difficult to trace compared to original tension, has been detected from 54 countries. In fact, the subvariance is likely to drive a third covid wave in several states including Delhi, Gujarat, Karnataka.
Omicron subvariant BA.2 hard to track:
Explain why it is more difficult to be tracked, previous experts show, the BA.1 omicron version is easy to track it missing one of the three target genes used in general PCR tests. The case that shows this pattern is assumed by default caused by BA.1. However, BA.2 does not have the same lost target gene Therefore, scientists monitor the same way as the previous variant, including Delta.
Omicron subvariant BA.2 spreads fast and can infect vaccinated:
Some studies have quoted that this variant in the question spread faster than BA sub-variants omicron.1. The British Health Security Agency has suggested that household transmission is higher among contacts of infected people BA.2 (13.4%) compared to other Omicron cases (10.3%). Meanwhile, Danish health officials estimate that BA.2 may be 1.5 times more contagious from BA.1 Ba.2 Subvariant also has immune evasive properties and relative to BA.2, it is best to infect individuals that have taken the booster dose.
What did WHO say about Omicron subvariant BA.2?
With regard to the cousin close to Omicron BA.1, the head of the World Health Organization (WHO) emphasized the need to continue tracking emerging variants, including the OMICRON sub-lineage BA.2. “This virus will continue to evolve, so we call countries to continue testing, surveillance and sequencing,” he said Tedros Adhanom Ghebreyesus pointed out that since Omicron has been spotted for the first time in Southern Africa, there were nearly 90 million cases reported to WHO – more than at 2020. and while the new variant Covid is known to be sweeter, he stressed that “we are now starting to see a very worrying increase in deaths in most parts of the world.”
