Eight more children died of influenza this week, bringing the season total to 52.
The loss of activity is equivalent to 15% of the US population becoming completely immobile for 1 day.
Adult COVID-19 patients also infected with the flu are 4 times more likely to need mechanical ventilation and 2.4 times more likely to die.
The roadmap offers a powerful opportunity to leverage advances in vaccine science to better protect against influenza, including pandemic flu.

The US Department of Homeland Security (DHS) has done a poor job of managing supplies of personal protective equipment (PPE) and antiviral medications to protect its workforce during an influenza pandemic, the department's Office of Inspector General (OIG) has found.
An H7N2 avian flu virus isolated from the farm of a Chinese man who had contracted H7N9 avian flu is a novel reassortant of H7N9 and H9N2 viruses, Chinese researchers reported yesterday in Emerging Infectious Diseases.
Saudi Arabia reported another MERS-CoV (Middle East respiratory syndrome coronavirus) case today, the second in 2 days, following a 13-day spell without any cases.
The new case involves a 52-year-old Saudi woman in Dammam, the same location as the case reported yesterday in a 60-year-old man. The new patient, who is not a healthcare worker, is hospitalized and has a preexisting disease, the Saudi Ministry of Health (MOH) said.
Researchers who sifted data from 12 recent influenza seasons in Finland concluded that about 42% of influenza B cases involved strains that were not targeted by the vaccine, which they say supports the inclusion of both influenza B lineages in seasonal flu vaccines.
In a study designed to simulate how the pandemic 2009 influenza (pH1N1) virus might have evolved, researchers say it took only nine passages in pigs for a virus to gain "greatly enhanced virulence and transmissibility" in pigs, guinea pigs, and ferrets.
A chikungunya candidate vaccine developed using noninfectious virus-like particles (VLPs) has been shown to provide long-term protection against multiple genotypes of the disease, according to results of the first human trial, conducted by researchers from the National Institute of Allergy and Infectious Diseases (NIAID) and published today in The Lancet.
The number of travel-related US chikungunya cases has grown to 580, an increase of 96 in the past week, the Centers for Disease Control and Prevention (CDC) said today in its weekly update. The number of locally acquired cases stayed at 4, for 584 total US cases.
H7N9 avian flu, which emerged in humans in China in the spring of 2013 and has since caused more than 450 cases, was found to replicate well in both the upper and lower respiratory tracts of cynomolgus macaques, a model for humans, and to show extended replication in the upper tract, indicating the possibility of prolonged shedding and transmissibility, say findings of a study today in mBio.
The neuraminidase inhibitor laninamivir, made by Biota Pharmaceuticals Inc. of Alpharetta, Ga., failed to perform better than a placebo at alleviating influenza symptoms in a phase 2 trial, the company said in a press release today, adding that it will no longer develop the drug.
An analysis of seven children infected with H7N9 avian influenza during the outbreak's second wave in China found that the illnesses were mild, a phenomenon that could contribute to spread of the virus. Researchers from China's Guangdong province published their findings today in an early online edition of the Pediatric Infectious Disease Journal.
