The ‘five pandemics’ driving 1 million U.S. Covid deaths – STAT

Officially, the U.S. will almost certainly reach an awful milestone in the next two weeks: its one millionth recorded Covid-19 death. In reality, this milestone was likely unofficially crossed days or weeks ago, and we’ll never know the exact toll or the identity of the pandemic’s actual millionth victim. Nor are humans well-equipped to fully grasp loss on this scale, let alone the magnitude of a global toll estimated to be as high as 14.9 million.

What we can learn from vaccinated covid deaths – Washington Post Podcast

Two new Omicron variants are spreading. Will they drive a new U.S. surge? – National Geographic

New versions of Omicron are again causing a surge of COVID-19 cases in South Africa, and studies show that these new subvariants are so different from the original version of Omicron that immunity generated from a previous infection may not provide much protection. Dubbed BA.4 and BA.5, the new subvariants are nearly identical to each other, and both are more transmissible than the Omicron BA.2 subvariant. In South Africa, they replaced the BA.2 strain in less than a month. They are now responsible for a spike in South Africa’s COVID-19 cases, which have tripled since mid-April.

What We Know About All the Omicron Subvariants – Including BA.2.12.1, BA.4, and BA.5. – New York Magazine

Whether you’re paying attention to the latest phase of the pandemic or not, the coronavirus is still evolving, and the subvariants are starting to add up. After two new variations of the Omicron strain were recently detected in the United States, there are now at least four Omicron subvariants circulating in the country. BA.2 is the still the most dominant and has driven the rise in cases across much of the U.S., but BA.2.12.1 appears to be even more transmissible, as do the newest strains, BA.4 and BA.5, which are expected to cause another wave of infection in South Africa. Below is a primer on everything Omicron and what impact its sublineages may have.

Most COVID Transmission Is Still Asymptomatic – MedPageToday

Some 60% of spread starts with those who have no symptoms, and that may be higher with Omicron.
