Get ready to learn more Greek letters. Scientists warn that omicron’s whirlwind advance practically ensures it won’t be the last version of the coronavirus to worry the world.
Fastaff travel nurses Lydia Mobley and Alex Stow describe the exhausting COVID fight on the front lines, and share a story of hope amid the heartbreak.
Omicron is more likely than delta to reinfect individuals who previously had COVID-19 and to cause “breakthrough infections” in vaccinated people while also attacking the unvaccinated. The World Health Organization reported a record 15 million new COVID-19 cases for the week of Jan. 3-9, a 55% increase from the previous week.
A variant could also achieve its main goal - replicating - if infected people developed mild symptoms initially, spread the virus by interacting with others, then got very sick later, Ray explained by way of example. Another potential route: With both omicron and delta circulating, people may get double infections that could spawn what Ray calls “Frankenvariants,” hybrids with characteristics of both types.
