Though flu activity decreased slightly last week, a wave of H3N2 virus activity has led to severe illnesses across the country and four more children have died from the disease, according to this week’s FluView report from the Centers for Disease Control and Prevention (CDC).
This is the second week in a row the CDC recorded more H3N2 cases that H1N1, the virus subtype that dominated the first part of the 2018-19 flu season.
“H3N2 viruses are typically associated with more severe illness in older adults, and flu vaccine may protect less well against H3N2 illness in older adults, making prompt treatment with flu antivirals in this age group especially important during the current period of H3N2 predominance,” the CDC said today in a summary of the report.
Though seasonal flu vaccination is still recommended while influenza is circulating, the CDC said the use of antivirals is an important “second line of defense.”
