The final two flu seasons within the U.S. have been mercifully gentle—one of many few silver linings of the pandemic, as COVID-19 mitigation measures doubtless additionally prevented many instances of influenza.
However our luck might run out this 12 months. Australia, which frequently serves as an (imperfect) predictor of what’s to come back for the U.S., has had its worst flu season in half a decade this 12 months, CNN experiences. Flu season additionally began early in Australia this 12 months, one other potential harbinger of what’s to come back within the Northern Hemisphere.
Dr. Alicia Fry, chief of the epidemiology and prevention department inside the U.S. Facilities for Illness Management and Prevention’s (CDC) influenza division, cautions that “when you’ve seen one flu season, you’ve seen one flu season”—that means the virus is unpredictable and guesses about it aren’t at all times correct. “Whether or not it is going to be a extreme season or a light season, or what to anticipate, or what viruses may flow into—that we actually simply don’t know,” Fry says.
Nonetheless, there are some components that would arrange the U.S. for a extra critical flu season this 12 months, says Dr. Brandon Webb, an infectious illness specialist at Utah’s Intermountain Medical Heart. Flu season severity varies fairly a bit from 12 months to 12 months, relying on components together with immunity within the inhabitants and which influenza pressure is circulating. “People who get influenza the 12 months prior in all probability carry over some incomplete or partial immunity,” Webb explains. Since few individuals obtained contaminated through the previous two flu seasons, “we’re taking a look at globally, and particularly within the U.S., file low neighborhood immunity ranges to influenza.”

The up to date pictures can be found to adolescents, youngsters, and adults who’re not less than two months out from their final COVID-19 vaccine dose (although some specialists suggest ready a bit longer). In the meantime, the CDC recommends getting a flu shot by the top of October.
“If an individual needs to get each on the identical time, they will,” Fry says. In a Sept. 6 press briefing, White Home COVID-19 Response Coordinator Dr. Ashish Jha concurred. “I actually consider that is why God gave us two arms—one for the flu shot and the opposite one for the COVID shot,” he stated.
Sometime, it might be even simpler to get twin safety towards COVID-19 and the flu. Vaccine makers Moderna and Novavax are engaged on pictures that may goal each viruses in a single injection. It’s not clear if or when these mixture pictures could be accessible, however their growth provides a glimpse into what dwelling with each COVID-19 and influenza might appear like shifting ahead.
Many unknowns stay about even this 12 months’s looming flu season. Webb recommends keeping track of each COVID-19 and influenza charges and taking precautions accordingly. Individuals at greater danger for extreme respiratory illness, together with aged individuals and people with underlying circumstances, may wish to think about carrying a masks in crowded settings.
No less than one factor makes Webb optimistic about this 12 months’s flu season: Regardless of all of the discuss of pandemic fatigue, he thinks there’s been a cultural shift in the way in which individuals handle infectious illnesses.
“Persons are, basically, way more conscious now in regards to the significance of an infection management,” Webb says. “I’d hope that we have now a distinct tradition by way of recognizing that if you’re ailing, it’s greatest to remain residence.”
