Flu season already hitting exhausting throughout half of the US


About half of the US – 22 states, together with Washington, DC, New York Metropolis and Puerto Rico – is reporting excessive or very excessive respiratory sickness exercise, as flu season sweeps by the nation weeks sooner than traditional.

A number of respiratory viruses are circulating nationwide – together with flu, RSV and the virus that causes Covid-19 – and the US Facilities for Illness Management and Prevention tweeted Thursday that flu is contributing to a “important proportion” of that circulation.

And influenza exercise continues to extend: After practically doubling within the final week of October, the variety of flu sicknesses, hospitalizations and deaths this season took one other important soar within the first week of November. The CDC now estimates that there have been not less than 2.8 million sicknesses, 23,000 hospitalizations and 1,300 deaths from influenza as of November 5.

The flu is notoriously exhausting to foretell.

“Among the many individuals who examine flu, there’s a little bit saying: ‘If you happen to’ve seen one flu season, properly, you’ve seen one flu season,’ ” stated Dr. William Schaffner, a professor within the Division of Infectious Illnesses at Vanderbilt College Medical Heart and medical director of the Nationwide Basis for Infectious Illnesses. “The implication is that they’re all a little bit bit totally different from one another, and that’s definitely the case.”

This season, there have been about 5 flu hospitalizations for each 100,000 folks, charges usually seen in December or January, CDC knowledge reveals. And in the latest week, about 13% of lab checks – greater than 1 in 8 – had been optimistic for influenza, up from 9% the week earlier than.

Though the numbers are particularly excessive for this time of yr, consultants say the traits are in any other case following an anticipated sample, and the early arrival of flu season doesn’t essentially imply it’ll last more or be extra extreme.

“The image is fairly constant throughout our totally different items of surveillance. There’s nothing there that makes me suppose that this virus is de facto totally different and inflicting extra extreme illness than we see usually with flu,” stated Lynnette Brammer, an epidemiologist who leads the CDC’s home influenza surveillance staff. “Flu may cause extreme outcomes, nevertheless it’s not out of proportion this yr in comparison with earlier years. It’s not like we’re seeing numerous hospitalizations with out numerous sickness.”

Flu exercise has been highest within the South, CDC knowledge reveals. Information from Walgreens that tracks prescriptions for antiviral therapies corresponding to Tamiflu suggests hotspots centered in Mississippi and Alabama, spreading from the Gulf Coast space, together with Houston and New Orleans, as much as Nashville.

As flu smolders within the South, RSV is displaying early indicators of slowing within the area, CDC knowledge reveals, even because it continues to ramp up in different components of the nation.

Nationwide, practically 1 in 5 PCR checks for RSV had been optimistic within the first week of November, reaching ranges that the South noticed a month in the past. However in that area, fewer than 1 in 7 checks are actually optimistic for RSV.

RSV is a standard respiratory virus that may trigger severe sickness, particularly in youthful infants, and it’s saved pediatric hospitals extra full than traditional in current weeks.

Regardless of the enhancements within the South, general burden on pediatric hospitals nationwide has not eased. Greater than three-quarters of pediatric hospital beds and pediatric ICU beds have been in use for the previous few weeks – up from a median of about two-thirds full over the previous two years, in response to federal knowledge.

On Thursday, Dr. Brian Cummings, medical director of the Division of Pediatrics at Mass Basic for Youngsters, stated they’ve seen round 2,000 circumstances of RSV in October, and greater than 1,000 within the first week of November.

“It’s been escalating and been fairly extreme,” Cummings stated throughout a information convention Thursday.

Most infections have been handled in pressing care amenities and within the emergency division, and individuals are despatched dwelling, Cummings stated. “However even when simply 10 p.c of these want hospitalization, it creates numerous stress on well being care amenities, and so what we’re seeing is we’ve had over 250 hospitalizations for RSV alone on prime of the opposite circulating viruses,” he stated.

The pediatric ICU is full, Cummings stated, and 7 sufferers are ready to be transferred in.

Throughout the nation, the specter of Covid-19, whereas considerably lower than it was a yr in the past, stays.

Practically 25,000 folks had been admitted to the hospital with Covid-19 within the first week of November, in response to CDC knowledge, a tempo that’s forecast to carry regular for the following month, not less than.

As a number of respiratory viruses proceed to unfold, consultants emphasize the significance of vaccination, which is out there for 2 of the three viruses in heavy circulation. However these numbers are decrease than perfect.

One in 5 folks nonetheless hasn’t gotten their first Covid-19 vaccine shot, CDC knowledge reveals, and fewer than 10% of the US inhabitants has gotten the up to date Covid-19 booster.

And tens of millions fewer flu vaccines have been distributed this season than at this level in earlier years.

“You are worried when you might have an early season that individuals simply haven’t had time to get vaccinated,” Brammer stated. “However vaccine is the very best software that we’ve got to stop these extreme outcomes.”
