Flu Taking a Toll, Pediatric Deaths Hit 17-Year High

- Northern and western states are now being hit hard.
- Currently the influenza B strain is appearing most often around the country.
- The CDC announced high numbers of pediatric deaths related to the flu.
The United States may be gearing up for one of the worst flu seasons in years, health experts predict.
The
Centers for Disease Control and Prevention (CDC) reported Friday that there have been 32 pediatric deaths so far this season. That’s the most flu-related deaths we’ve seen in children since the
CDC started tracking flu numbers
17 years ago.
That’s the most flu-related deaths we’ve seen at this point in the season in years, though that’s largely due to the earlier start we got this year. (To put this into perspective, at this time last year, there had only been
16 pediatric deaths.)
Most of the pediatric deaths have been linked to
influenza B — a strain young children are particularly susceptible to. Now, influenza A appears to be gaining momentum, upping the risk that this flu season will be even more severe than expected.
In total, there have been at least 9.7 million cases of the flu, at least 87,000 flu-related hospitalization, and up to 12,000 deaths, according to the
CDC.
Forty-six states plus Puerto Rico are currently experiencing widespread flu activity, though the type of strain and incidence vary from region to region.
“Since mid-December, influenza activity has really ramped up,” said
Marie-Louise Landry, MD, a Yale Medicine infectious disease expert and the director of the Yale Clinical Virology Laboratory. “All four influenza strains are circulating, but so far A/H1 and B/Victoria have been more common.”
The vaccine isn’t perfect, but it helps
The flu vaccine is never perfect — flu strains mutate and change each and every year, so it’s impossible for the vaccine to successfully target every flu variation.
Experts are also seeing more influenza B/Victoria cases than we typically do — a strain that’s not comprehensively covered by
this year’s vaccine.
“While early in the season, all the circulating strains of influenza A/pdmH1 and influenza B/Yamagata tested so far have been similar to the strains in the vaccine, but 58 percent of influenza B/Victoria strains and only 34 percent of influenza A/H3 tested matched the vaccine strains,” Dr. Landry told Healthline.
Health officials are still working on those estimates, too, so they’ll likely change a bit as the season progresses.
“Ideally, this number should be as high as possible, but often with influenza the virus may genetically drift away from an exact match with the virus,” said
Amesh Adalja, MD, an infectious disease physician and senior scholar at the Johns Hopkins University Center for Health Security.
Because the vaccine seemed to miss the mark a bit with the most predominant strain (B/Victoria), the United States might see more people continue to come down with this type of flu.
That said, even if you do contract one of these strains, the vaccine will reduce the length and severity of your symptoms.
Certain strains are worse in certain areas
All four strains (A, B, C, and D) are currently circulating, but
different strains seem to be striking more in various parts of the country.
In general, B and A strains cause a similar illness: fatigue, cough, sore throat, body aches, chills, and fever.
A
study from 2014 found that adults with influenza A or B had the same length hospital stays and comparable rates of death and intensive care admission.
However, B/Victoria — the predominant strain we’re seeing in the U.S. — is thought to cause a more severe illness in children. In fact, a
2016 study found that influenza B was more likely to cause death in children ages 16 and younger.
“On a national level, influenza B is outnumbering influenza A which is unusual, but the predominant virus may vary with the region of the country, the age of the patient, and whether the person was sick enough to be admitted to a hospital,” Landry said.
B strains are dominating in Southern states, including Texas, Louisiana, Alabama, and Georgia. The region between Virginia and Pennsylvania is also seeing more illnesses linked back to B strains.
But other areas — such as the Carolinas and the Northeast — are seeing more of the A strain.
Certain Midwestern states, including Nebraska, Iowa, Illinois, and Indiana, are reporting more A strain cases as well.

Expect flu activity to continue increasing
According to Dr. Adalja, the worst of the flu season may still be on the way.
“I expect that flu will continue to rise in activity as we have not reached a peak yet,” Adalja said, adding that he suspects flu season will peak earlier than usual this year given the accelerated rate seen so far.
Flu season typically peaks in February, but health officials say it’ll likely peak sometime between December and February. (There’s a
40 percent chanceTrusted Source it’s already peaked, and a 35 percent chance it’ll peak in January.)
People who haven’t yet been vaccinated should make it a priority to do so now.
“It’s not too late to get vaccinated as we have many more weeks of flu season left to go. Flu vaccination is always the best way to prevent flu and its potentially serious complications,” the CDC emailed in a statement, noting that a vaccination location can be found at
www.vaccinefinder.org.
As expected, flu activity picked up over the holidays. There have now been at least 6.4 million flu illnesses, 55,000 hospitalizations, and 2,900 flu-related deaths.
