US Faces Dual Threat: Super Flu & New Covid Strain

As winter intensifies, the United States is contending with a significant rise in both influenza and a new variant of Covid-19. Recent data indicates a nearly 50 percent increase in flu-related hospitalizations compared to the previous week, with 'very high' transmission noted in several states including New York and Colorado. This surge is largely attributed to a new H3N2 subclade K, a strain unfamiliar to many immune systems, increasing vulnerability to severe illness.

In parallel, the Covid strain XFG, or Stratus, has become dominant, reportedly causing a unique 'razor blade' sensation in the throat. While flu symptoms are typical, this novel strain's novelty poses a heightened risk. Both illnesses are predicted to worsen in the upcoming weeks, prompting some schools to close and hospitals to reintroduce masking measures for patients and staff.

Flu season typically spans from October to May. The CDC recommends annual vaccination, with 40 percent of American adults having received the flu shot by late November. For Covid-19, while nationwide viral activity is currently low, nine states are experiencing worsening spread. The XFG variant's prevalence in wastewater, though slightly declining, remains substantial, highlighting the ongoing public health challenge.
