The U.S Centers for Disease Control and Prevention (CDC) warns of a surge in respiratory illnesses across the country, with 15 states facing "high" or "very high" levels of infection.
Respiratory illnesses like flu, COVID-19, respiratory syncytial virus (RSV) infection and common cold exhibit "very high" levels of prevalence in Louisiana and South Carolina, followed by "high levels" in California, New Mexico, Mississippi, Alabama, Tennessee, Georgia and New York City. The activity levels of infections are measured based on the percentage of visits to enrolled outpatient healthcare providers or emergency departments for fever, cough or sore throat.
