CIDRAP:
More Than 65 Million People Around The World May Have Long COVID
Worldwide, at least 65 million people have long COVID, and that is likely an underestimate, finds a review article published late last week in Nature Reviews Microbiology. ... The researchers said that the number of affected COVID-19 survivors was based on the estimated global rate of 10% of infected people and the more than 651 million documented cases. They cited the lack of polymerase chain reaction (PCR) test availability at the beginning of the pandemic and the high false-negative rate of rapid antigen tests as reasons for suspecting an undercount.

Covid-19 Immunity Lasts At Least A Year After Infection Plus Shots
People who have been both previously infected and vaccinated against Covid-19 get long-lasting protection against severe disease and hospitalization, a large international study found. The combination prevented more than 97% of severe disease or hospitalization for up to 12 months after infection or initial immunization, whichever was most recent, according to a report from the World Health Organization.

‘Hybrid’ COVID Immunity From Vaccination And Infection Is Superior To That From Infection Alone, New WHO-Backed Study Finds
So-called “hybrid immunity”—from vaccination and infection—offers better protection against severe disease and hospitalization from COVID than immunity from infection alone, according to a new study published in The Lancet. The study provides public health officials and policy-makers with recommendations on priorities when running vaccination campaigns, and on the potential frequency of booster shots going forward. The World Health Organization, which collaborated on the study, touted it Wednesday for “demonstrating the advantages of vaccination even after people have had COVID-19.” (Prater, 1/18)

COVID Couldn’t Kill The Handshake
Mark Sklansky, a pediatric cardiologist at UCLA, has not shaken a hand in several years. The last time he did so, it was only “because I knew I was going to go to the bathroom right afterwards,” he told me. “I think it’s a really bad practice.” From where he’s standing, probably a safe distance away, our palms and fingers are just not sanitary. “They’re wet; they’re warm; they’re what we use to touch everything we touch,” he said. “It’s not rocket science: The hand is a very good medium to transmit disease.” (Wu, 1/18)
