It's been overshadowed by the new coronavirus outbreak in China, but this year's flu season could be near its peak. At least 14,000 people have died and 250,000 have already been hospitalized during the 2019-2020 flu season, according to estimates from the U.S. Centers for Disease Control and Prevention. More than 26 million Americans have fallen ill with flu-like symptoms. There is a deadly respiratory virus that is circulating throughout the United States, and it is at its peak. It is not novel coronavirus," said Dr. Pritish Tosh, an infectious disease specialist with the Mayo Clinic. This flu season ... started early, in October, with an unusual wave of influenza B virus. Influenza B is less likely than other strains to mutate and become more virulent. That means it poses a greater threat to young people than to older folks, who may have gained immunity because they encountered the strain before. There have been 105 flu-related deaths among children this season, a higher total at this point of the year than any season in the past decade. Two-thirds of these deaths were associated with influenza B viruses, the CDC noted. More recently, a second wave of influenza A viruses featuring the H1N1 strain has hit the United States, Tosh noted. "This has been an extended season, and we've certainly been seeing a lot of hospitalizations and bad outcomes from it," Tosh said. "We will likely continue to see high influenza activity for several weeks. We are probably at its peak right now. I sure hope it doesn't get much worse."
