U.S. health officials are preparing for a second wave of the winter flu season, complicated this year by similarities between flu symptoms and those of the coronavirus that has killed more than 1,500 in China and spread fear around the world.
A first round of seasonal flu, caused by a strain of influenza B, named B-Victoria for the city in which it was discovered, peaked in the United States in late December and then dropped off, according to the U.S. Center for Disease Control and Prevention.
However, the CDC says a second round of flu began in late January, caused by a strain of influenza A that is related to the swine flu that first appeared in 2009, and cases continue to increase.
While there have only been 15 confirmed coronavirus cases in the United States as of Friday, health officials have expressed concern that if the virus were to spread in the country, it could initially look like the spread of seasonal flu.
