Medical doctors are particularly involved about this latest flu A spike. Right here’s what they’re alarmed about probably the most:
Medical consultants are involved that charges are the very best they’ve been in over a decade.
As talked about, flu charges are at 15-year highs within the U.S., and we’re presently within the season’s second flu spike. Whereas it’s not unusual to have a second spike within the late winter, the extent at which individuals are getting sick isn’t regular, Kuritzkes mentioned.
“To put some numbers on it, at least here in Massachusetts, around 20 to 24% or so of emergency department visits in the last couple of weeks have been due to acute respiratory illness, and about 9% of those are due to flu A, and by comparison, less than 1% of visits have been due to either COVID or RSV,” Kuritzkes defined. So, most people who find themselves sick proper now are sick with flu, not one other virus.
“Initially I was optimistic it would be a good flu season since it started late this year, but now we are at levels we have not seen in years,” mentioned Dr. Scott Roberts, an infectious illness physician at Yale Medication in Connecticut advised HuffPost by way of electronic mail.

Whereas Kuritzkes mentioned he hadn’t heard this statistic particularly, he famous that it may actually have an effect on flu charges within the nation.
“Children are much more likely to be in close physical contact with each other, especially very young children who may be in day care or preschool, as well as elementary-school-age kids,” he mentioned. “And kids who contract influenza in a school setting may then bring it home and cause the influenza to spread throughout the household.”
The low vaccination charges additionally align with the “general increased vaccine hesitancy that we’ve seen over the last couple of years,” Kuritzkes mentioned.
Whereas youngsters typically have much less extreme sickness than older adults or these with sure medical circumstances, it’s nonetheless necessary for teenagers to get vaccinated, he added.
“There are some children who have medical conditions that place them at risk for severe flu, and also because children can serve as a vector for spread of influenza,” Kuritzkes defined.

In keeping with Roberts, “Hospitalizations lag behind positive tests by a few weeks, so I would expect [hospitalization] rates to continue to increase for the next few weeks at a minimum.”
Flu deaths are greater than COVID deaths for the primary time for the reason that pandemic.
In keeping with new knowledge printed by the Facilities for Illness Management and reported by CBS, flu deaths had been greater than COVID-19 deaths through the remaining week of January. This marks the primary time flu deaths have exceeded COVID deaths for the reason that begin of the pandemic.
Whereas that is regarding, Kuritzkes identified that “we are not, to my knowledge, seeing more severe influenza.”
“I’ve not seen any data to suggest that the rate of mortality [has] increased. Of course, deaths will increase with the number of cases, but … there’s nothing to suggest that this is a more severe strain of influenza compared to previous years,” he mentioned. “It’s just that many more people are getting sick.”
