Weekly Influenza Surveillance

Flu activity continues to decline and is below national baseline levels. However, activity remains elevated in parts of the country, including the northeast. Sporadic flu activity will continue to occur. While most flu activity occurs from October to May in the United States, flu viruses are detected year-round, including during the spring and summer months.

H3N2 viruses predominated earlier in the season, however, influenza B viruses have been more common in recent weeks. This season has been severe for people 65 years and older, with very high hospitalization rates being recorded.

Influenza antiviral drugs can treat flu illness. CDC recommends these drugs be used to treat people who are very sick or who are at high risk of serious flu-related complications who have flu symptoms. Early antiviral treatment works best.

High-Risk Patient With Possible Flu? Start Those Antivirals

High-risk groups include people aged 65 years and older, young children, pregnant women, and people with underlying medical conditions, such as chronic obstructive pulmonary disease, asthma, congestive heart failure, and diabetes. Observational studies have shown that influenza antiviral drugs can reduce serious flu complications, including hospitalization and death. CDC recommends beginning empiric antiviral treatment as soon as possible in all severely ill patients (including outpatients with severe progressive symptoms and those who develop such complications as pneumonia) and high-risk patients with suspected flu, without waiting for the results of influenza diagnostic tests.
