This flu season is on track to be one of the worst in 15 years – The Denver Post

With tens of thousands of patients flocking to hospitals and at least 37 children dead, this year’s flu season is shaping up to be the worst in nearly a decade – and it’s not over yet.

At a time when experts hoped new cases would start tapering off, federal health officials said Friday that the number of patients seeking care for flulike symptoms continues to rise sharply.

Nearly 12,000 people have been hospitalized with confirmed cases of flu, an increase of 3,000 in just one week, according to the Centers for Disease Control and Prevention. The latest report, for the week ending Jan. 20, shows the rate of people seeking care now rivals that of the swine-flu pandemic of 2009.

In Florida, West Boca Medical Center in Boca Raton has seen a surge of patients. “We think it may be peaking,” said Adam Leisy, head of the emergency room, “but who knows what the next few weeks will bring.”

Leisy said his hospital has been flooded with elderly snowbirds – often already dealing with chronic conditions and now wheezing from coughs and struggling with fever.

In California, some hospitals have pitched tents outside their ERs to cope with the crush of patients; some facilities there have flown in nurses from out of state. Doctors have worked double and triple shifts. In Chicago, a shortage of patient beds has left ambulances idling outside hospitals.

In New York, state leaders this week issued an emergency order allowing pharmacists to give vaccines to children.

The toll on children has been especially severe. CDC officials said the pediatric death count is likely to approach, if not exceed, the 148 deaths reported during the especially severe flu season of 2014 and 2015. That season ended with 56,000 flu-related deaths, 710,000 people hospitalized and 16 million who sought care from a clinician or hospital.

This year’s intensity has been driven by a particularly nasty strain of the virus known as H3N2. Another strain has also begun showing up, hitting baby boomers especially hard, CDC officials said Friday, although experts have not figured out exactly why.

CDC says the number of pediatric deaths is probably more than the 37 reported, because if often takes longer for deaths outside hospitals to be reported to authorities. The real number may be twice as high, officials said.

“You hear people talking about how serious it can get, but you never think it’s going to happen to you,” Anne LaMontagne, 41, said by phone as she sat by her son in Children’s Minnesota in Minneapolis.

In the space of five days, 9-year-old Grant went from having a sore throat to being rushed to the hospital, with doctors struggling to force more oxygen into his lungs to keep him alive.

The flu led to pneumonia. Her son’s lungs filled with mucus, preventing him from breathing. Doctors put the boy on a ventilator and stuck a probe down his throat to suction out vinelike threads of mucus from his lungs.

But his condition got worse. Last week, LaMontagne and her husband looked on with horror as doctors inserted a large tube into an unconscious Grant’s neck and connected him to a lung-bypass machine to give his body the oxygen his lungs could not.

The sight sent the couple fleeing to the hospital cafeteria. “We just cried and tried to breathe and talk each other through what was happening,” she said.

The treatment worked. Last Friday her son had recovered to the point that doctors woke him from sedation. “It all happened so fast,” his mother said Friday. “He’s a healthy boy. He swims. He’s never had any major illnesses.”

Two differences with this year’s flu is that it hit almost all states at the same time and has stayed at that high level nationally for three consecutive weeks, said Daniel Jernigan, who heads the CDC’s influenza division. In past years, the flu more commonly appeared in different parts of the country at different times.

The current season began in October, but there was a rapid ramp-up in January right after the holidays, probably triggered by children returning to school and spreading the virus, Jernigan said. In Florida and Texas, entire school districts have closed to stop further spread.

The burden of so many cases on hospitals, experts say, underscores the fragility of the country’s health-care system. Some hospitals are already strained to capacity on a normal day and could be overrun if a pandemic hits.

“The concern is that with an emergency, we could get to a tipping point, where the demands of community exceeds our capacity as a country,” said James Blumenstock, chief program officer for the Association of State and Territorial Health Officials.

The length and severity of a flu season is always notoriously hard to predict. Experts often look for clues in past seasons when the same strains of flu have dominated. In previous H3N2 seasons, flu activity remained active for an average of about 16 weeks but in some cases continued as long as 20 weeks.

“By that measure, we are about halfway there,” Jernigan said. “But it means we have several more weeks of flu to go.”

Already, this season has offered its share of surprises.

People over 65 are usually the ones with the highest hospitalization rates, with the second most affected group being children under 4. But officials have been taken aback in recent weeks to see that individuals with the second-highest hospitalization rate are between 50 to 64 years old.

“Baby boomers have higher rates of hospitalization than their grandchildren right now,” Jernigan noted with surprise.

It’s not clear why this is happening. Officials say one possibility may be the mix of viruses circulating this season and the different levels of immunity that people have developed to those viruses over time.

In addition, vaccination rates for adults under 65 are lower than those for seniors.
