According to the latest data from the Centers for Disease Control and Prevention (CDC), BA.5 accounts for 65% of all COVID-19 cases in the U.S.; in just two months, the subvariant managed to outcompete BA.2 and BA.2.12.1the two previously dominant subvariants.

Among 431 household contacts, 227 were classified as having a case of COVID-19 (attack rate [AR]=52.7%). The ARs among household contacts of index patients who had received a COVID-19 booster dose, of fully vaccinated index patients who completed their COVID-19 primary series within the previous 5 months, and of unvaccinated index patients were 42.7% (47 of 110), 43.6% (17 of 39), and 63.9% (69 of 108), respectively.
