Fall is approaching, and so is the possibility of what public health officials are calling a “twindemic” — overlapping epidemics of both COVID-19 and influenza.
A bad flu season coupled with continued COVID-19 outbreaks could increase people’s risk of fatal illness and overwhelm hospital capacity in communities already scrambling to treat coronavirus patients, experts say.
“I think it’s definitely a possibility and it’s something we’re all worried about,” said Dr. Eric Cioe-Pena, director of global health at Northwell Health in New Hyde Park, N.Y. “The trifecta of a bad flu season, a bad COVID resurgence and an Atlantic hurricane is our doomsday scenario. You could add in civil unrest around the election as a four-way doomsday scenario.”
The concern is so great that officials worldwide have been pressing for folks to get this year’s flu shot, even though it’s only now hitting the market.
Getting your flu shot “could at least blunt the effect of one of those two potential respiratory infections,” Dr. Anthony Fauci, director of the U.S. National Institute of Allergy and Infectious Diseases, told The New York Times.
Fauci shared his thoughts on vaccination in this video:
The U.S. Centers for Disease Control and Prevention usually purchases a half-million doses of flu vaccine for uninsured adults, but this year the agency increased its order by an additional 9.3 million doses, according to the Times.
But the protective strategies that officials have been promoting against COVID-19 — masking, hand-washing and social distancing — should reduce the risk of a twindemic.
“The same things we do to prevent COVID should work for another virus called influenza,” said Dr. Waleed Javaid, director of infection prevention and control at Mount Sinai Downtown, in New York City. “If we follow the same recommendations, they should be effective for influenza and for COVID, and we might not see as much spread of influenza as we’ve seen in previous years.”
Indeed, the Southern Hemisphere is in the middle of its flu season and has seen a dramatic decrease in flu cases thanks to protective measures adopted against the new coronavirus.
The Australian Experience
“In Australia, the flu cases are down around 99% compared with last year,” noted Dr. Amesh Adalja, a senior scholar with the Johns Hopkins Center for Health Security, in Baltimore.
Unfortunately, the United States probably won’t see this benefit because the nation has not fully embraced the recommended protections against COVID-19, Adalja continued.
“There is likely to be some effect, but the fact of the matter is even though we have all these measures for COVID, in the United States we haven’t really been as adherent to them as in other countries. We have to prepare for the fact that we may not get the Australian experience of influenza,” Adalja said.
A community facing a twindemic could soon find itself running out of hospital capacity, Adalja added.
Last year’s flu season was relatively mild, but still resulted in between 39 million and 56 million cases of flu, as many as 740,000 hospitalizations, and between 24,000 and 62,000 flu deaths, according to preliminary CDC estimates.
“You have to remember those viruses are going to compete for the same hospital beds, ICU beds, ventilators, personal protective equipment and even diagnostic test reagents,” Adalja said.
Doctors are particularly worried about people who catch one of the viruses and then the other, back-to-back.
“I would say a sequential infection could be really a major problem for somebody, to get hit twice in a row. They might have sustained lung damage from COVID and now have to deal with influenza,” Adalja said. “I would think the lung damage one would induce would make you more susceptible to a severe outcome with the other one.” www.HealthDayNews.com
