ISLAMABAD (our reporter):- After several weeks of fluctuating in positivity rate, the COVID-19 positivity rate has reached 3 percent in Pakistan, with 582 fresh cases reported during the last 24 hours, the National Institute of Health, Islamabad’s (NIH) data showed Monday morning.
The new infections were detected after diagnostic testing on 19,389 samples during last 24 hours.
Moreover, two persons lost their lives due to corona virus overnight, pushing the country’s COVID-19 death toll to 30,469.
Meanwhile, 178 coronavirus patients are being treated in critical care units of different medical facilities across the country.
BA5, part of the Omicron family, is the latest coronavirus variant to cause widespread waves of infection globally.
According to the World Health Organisation’s most recent report, it was behind 52 percent of cases sequenced in late June, up from 37% in one week.
In the United States, it is estimated to be causing around 65% of infections.
BA5 is not new. First identified in January, it has been tracked by the WHO since April.
Like its closely related sibling, BA4, BA5 is particularly good at evading the immune protection afforded either by vaccination or prior infection.
For this reason, “BA5 has a growth advantage over the other sublineages of Omicron that are circulating,” Maria Van Kerkhove, the WHO’s technical lead on COVID-19, told a news briefing on Tuesday.
For many people, this means that they are getting re-infected, often even a short time after having COVID-19. Van Kerkhove said the WHO is assessing reports of re-infections.
“We have ample evidence that people who’ve been infected with Omicron are getting infected with BA5. No question about it,” said Gregory Poland, a virologist and vaccine researcher with the Mayo Clinic in Rochester, Minnesota.
