IS BA.5 THE 'REINFECTION WAVE'? Well, here we go again. Once more, the ever-changing coronavirus behind COVID‑19 is assaulting the United States in a new guise — BA.5, an offshoot of the Omicron variant that devastated the most recent winter. The new variant is spreading quickly, likely because it snakes past some of the immune defenses acquired by vaccinated people or those infected by earlier variants. Those who have managed to avoid the virus for close to three years will find it a little harder to continue that streak, and some who recently caught COVID are getting it again. The Atlantic |
