The flu has further tightened its grip on the US. This season is now as bad as the swine flu epidemic nine years ago. A report out on Friday shows 1 of every 13 visits to the doctor in the US last week was for fever, cough and other symptoms of the flu. That ties the highest level seen in the US during swine flu in 2009.
And it surpasses every winter flu season since 2003, when the government changed the way it measures flu. “I wish that there were better news this week, but almost everything we’re looking at is bad news,” said Dr. Anne Schuchat, acting director of the Centers for Disease Control and Prevention.
Flu season usually takes off in late December and peaks around February. This season started early and was widespread in many states by December. Early last month, it hit what seemed like peak levels — but then continued to surge.
The season has been driven by a nasty type of flu that tends to put more people in the hospital and cause more deaths than other more common flu bugs. Still, its long-lasting intensity has surprised experts, who are still sorting out why it’s been so bad. One possibility is that the vaccine is doing an unusually poor job; US data on effectiveness is expected next week.
Some doctors say this is the worst flu season they’ve seen in decades. Some patients are saying that, too. Veda Albertson, a 70-year-old retiree in Tampa, was sick for three weeks with high fever and fluid in her lungs. She said she hadn’t been this sick from the flu since the 1960s, when she was a young mother who couldn’t get out of bed to go to the crib of her crying baby. “It was like ‘Wham!’ It was bad. It was awful,” she said of the illness that hit her on Christmas Day.
Heather Jossi, a 40-year-old Denver police officer and avid runner, said her illness last month was the worst flu she’s experienced. “I don’t remember aches this bad. Not for four days,” said Jossi. “It took me out.” Albertson said she got a flu shot, Jossi did not.
Last week, 43 states had high patient traffic for the flu, up from 42, the CDC reported. Flu remained widespread in every state except Hawaii and Oregon and hospitalisations continued to climb. “It’s beginning to feel like a marathon,” said Dr. Anthony Marchetti, emergency department medical director at Upson Regional Medical Center, a 115-bed hospital in rural Georgia. A quarter of the hospital’s emergency department visits are patients with flu, and the hospital has added nursing staff and placed beds in halls to accommodate the increase, he said.
But reports of deaths — some in otherwise healthy children and young adults — have caused growing fear and concern, health officials acknowledge. On Friday, Delisah Revell brought her 10-month-old daughter to the Upson Regional emergency room. “I heard how bad it is and I didn’t want to take any chances,” said Revell, who drove 30 minutes to get to the hospital in Thomaston.
The CDC said the amount of suspected flu cases at doctor’s offices and hospital emergency rooms last week matched that seen in 2009, when a new swine flu pandemic swept the world. Swine flu, also called pandemic H1N1, was a new strain that hadn’t been seen before. It first hit that spring, at the tail end of the winter season, but doctor visits hit their height in late October during a second wave.
This flu season, hospitalisation rates have surpassed the nasty season of the winter of 2014-2015, when the vaccine was a poor match to the main bug. Health officials have said this year’s vaccine targets the flu viruses that are currently making people sick, including the swine flu virus that has become a regular winter threat. However, preliminary studies out of Australia and Canada have found the shot was only 10 to 20% effective in those countries against the H3N2 strain that’s causing the most suffering this winter.
Doctors say they’re a bit bewildered as to why this season is so intense. “It is surprising,” said Dr James Steinberg, chief medical officer at Emory University Hospital Midtown in Atlanta. “It’s not a hugely new strain. So why is it so severe? I don’t think we know.”
