CDC issues warning on respiratory illnesses as cases surge across the U.S.

The Centers for Disease Control and Prevention (CDC) has issued an alert regarding a "high" level of respiratory illness activity in the U.S., with COVID-19, influenza, and respiratory syncytial virus (RSV) leading the surge.

States with the highest activity

New Hampshire currently tops the list with "very high" respiratory virus activity, while 11 other states, including Arizona, Georgia, and Texas, are classified as having "high" activity. Most states fall into the "moderate" category, while a few report "low" activity, according to CDC data.

Rising case numbers and hospitalizations

The CDC reports increasing emergency department visits and positive test rates for COVID-19, flu, and RSV. Since the start of the flu season, there have been approximately:

• 3.1 million flu cases

• 37,000 hospitalizations

• 1,500 flu-related deaths, including nine pediatric deaths.

COVID-19 cases are also on the rise, with wastewater analysis and laboratory data suggesting continued growth in the coming weeks. Meanwhile, RSV hospitalizations are increasing among children and older adults in certain areas.

Vaccination rates remain low

Despite the availability of vaccines for flu, COVID-19, and RSV, coverage remains suboptimal:

• Flu vaccine: 41.9% of adults, 42.5% of children

• Updated COVID-19 vaccine: 21.4% of adults, 10.3% of children

• RSV vaccine: 43.7% of adults aged 75+

Low vaccination rates leave many vulnerable, particularly during the winter months when respiratory illnesses typically spike.

CDC recommendations

The CDC urges people to get vaccinated against flu, COVID-19, and RSV, particularly those in high-risk groups such as young children, older adults, and individuals with underlying health conditions. Basic precautions like wearing masks in crowded places, frequent handwashing, and staying home when sick are also advised to curb the spread of respiratory illnesses.

As respiratory viruses continue to impact communities nationwide, health officials emphasize the importance of proactive measures to protect against severe outcomes.
