The United States is experiencing an increase in COVID-19, flu, norovirus, and RSV infections over the holidays, with experts forecasting that this will worsen when flu season peaks.
Norovirus cases reached all-time highs since 2012, while RSV hospitalizations increased by 40% in two weeks.
Hospitals in states such as California and Illinois have reintroduced emergency procedures. To limit the spread, New York officials recommend people to wear masks in busy settings.
