The Centers for Disease Control and Prevention is warning about RSV, a cold-like respiratory disease, amid a spike in cases round the southern U.S.

The public health agency issued an official advisory on Thursday urging clinicians and caregivers to be watching out for the virus, which is known to attack the airways and lungs. Experts said they have seen an uptick in favorable infections in at least a dozen states, including Florida, Georgia, Mississippi, Texas, Kentucky, North Carolina and South Carolina.

“Due to this increased activity, CDC encourages broader testing for RSV among patients presenting with acute respiratory illness who test negative for SARS-CoV-2, the virus that causes COVID-19,” the advisory states. “RSV can be associated with severe disease in young children and older adults.”

Cases of this virus normally peak during the autumn and winter, the CDC said, leading to around 58,000 hospitalizations in the U.S. each year.

Infants and children are at highest risk of severe illness due to RSV, as are older adults who have underlying medical conditions, according to the agency.

Others can become very ill, however. Every year, 177,000 adults over 65 have to hospitalized and an estimated 14,000 expire because of RSV infection, based on CDC data.
