In brief
Flu infections in the U.S. have sharply escalated over the holidays, marking this season as potentially severe, outpacing last year's already harsh strains. With 45 states reporting high activity levels, health officials express concerns over the H3N2 virus, particularly its new subclade K variant that's linked to higher hospitalization rates. While COVID-19 cases also rise, they remain less prevalent than flu. Experts suggest getting vaccinated to curb the rising tides of illness.
NEW YORK (AP) — The U.S. is experiencing a surge in flu cases this holiday season, prompting health experts to declare it a potentially severe year for influenza. Recent data indicates that flu activity is already outpacing last season's high hospitalization rates, with 45 states reporting elevated levels of flu cases, up from 30 just a week prior.The predominant strain this year appears to be the A H3N2 variety, which historically results in more hospitalizations among older adults. Alarmingly, a new variant of this strain, known as subclade K, accounts for 90% of reported infections and differs from the current flu vaccine strain, raising concerns about its effectiveness.With flu seasons traditionally peaking in January or February, it's uncertain how significant an issue this variant will become, especially as COVID-19 cases also rise but remain less widespread. Experts are advising everyone aged 6 months and older who hasn't yet been vaccinated to consider getting the flu shot to help mitigate illness during this challenging season.
