Coronavirus Update: Cases climb in Southeast Asia and Europe in latest week as BA.4 and BA.5 subvariants take hold

The World Health Organization said COVID cases were lower overall in the week through June 19, but moved higher in Southeast Asia, the Eastern Mediterranean and the European regions as the BA.4 and BA.5 subvariants continued to take hold.

Those two subvariants have been detected in 62 and 58 countries respectively, while the earlier BA.2.12.1 subvariant has been detected in 69 countries but is decreasing in prevalence, the agency said in its weekly epidemiological update.

“BA.4 and BA.5 have a constellation of genetic mutations that differ
from BA.2, including a shared mutation at S:L452 which has been associated with higher transmissibility,” said the update.

And while that has lead to a surge in hospitalizations and ICU admissions in some countries, there is still no evidence to suggest the two are more lethal than other variants, it said.

Media reports are highlighting the chaos at many airports in Europe, where labor shortages are meeting increased demand for travel as pandemic restrictions are lifted.

Airlines and airports that slashed jobs during the depths of the COVID-19 crisis are struggling to keep up, the Associated Press reported, creating long security lines at airports such as Schiphol in the Netherlands, where one passenger was confronted by a line that snaked out of the terminal and into a big tent along a road before doubling back inside the main building.

Adding to the frustration on the ground, many airlines are canceling flights because of the security staff issues and airlines are warning travelers to get their early in case of such delays.

London’s Gatwick and Heathrow airports are asking airlines to cap their flight numbers. Discount carrier easyJet is scrapping thousands of summer flights to avoid last-minute cancellations and in response to caps at Gatwick and Schiphol. North American airlines wrote to Ireland’s transport chief demanding urgent action to tackle “significant delays” at Dublin’s airport.

In the U.S., there have been 7,655 delayed flights on Thursday, according to Some 2,153 flights have been canceled, the tracker shows, while its “Misery Map” shows most of those are happening in Boston and New York.

• Top Tennessee Republican House leaders on Wednesday urged Gov. Bill Lee to delay the state’s health department from distributing and promoting the COVID-19 vaccines to infants, toddlers and preschoolers, the AP reported. The lawmakers added that the “COVID-19 emergency has long passed in Tennessee” though that declaration is disputed by public health experts. The letter came just days after Florida raised eyebrows for being the only state in the country not to preorder the vaccine for its toddlers. Florida has since bent to pressure from medial professionals and the federal government.

• Enanta Pharmaceuticals 

filed a lawsuit against Pfizer

 over Paxlovid, alleging that the COVID-19 antiviral expected to bring in $22 billion in sales this year is based on a patent first filed by Enanta scientists. The suit, which was filed Tuesday in U.S. District Court in Massachusetts, alleges that Enanta filed an application with the U.S. Patent and Trademark Office “describing coronavirus protease inhibitors invented by Enanta scientists” in July 2020. Pfizer’s patent for Paxlovid appears to have been filed three months later, and Enanta’s patent “does appear to cover the chemical space Paxlovid is in,” RBC Capital Markets analyst Brian Abrahams told investors this week.

The eastern province of Zhejiang will now require overseas arrivals to do seven days of quarantine, followed by another seven in home isolation.
