New Flu Drug and Fast Flu Facts


In October 2018, the U.S. Food and Drug Administration approved a new flu drug, Xofluza (baloxavir marboxil). This single-dose, oral prescription drug is the first flu treatment approved by the FDA in nearly 20 years. With flu season still in effect, this new drug can bring relief to the rising number of flu cases in the United States.

All About Xofluza

The new flu drug, Xofluza, was discovered by Japan’s Shionogi & Co., Ltd. and was approved in February 2018 by the Japanese Ministry of Health, Labour and Welfare for treatment of influenza types A and B. It
was then approved by the FDA based on results from two studies including more than 1,800 people. Participants were given Xofluza, a placebo, or another antiviral flu treatment within 48 hours of experiencing flu symptoms. In both trials participants who were given Xofluza experienced relief from symptoms sooner than those given the placebo or the other antiviral drug.

This drug can only be prescribed in patients 12 years of age and older who have been symptomatic for no more than 48 hours. The more common side effects include bronchitis and diarrhea. With this new drug on the market, doctors are still advising that everyone, especially pregnant women, children and the elderly, get the flu shot.

Fast Flu Facts

The U.S. Centers for Disease Control and Prevention now provide a Weekly FluView Report. All data provided is preliminary and can change as new reports are received. Here are some fast facts about this flu season:

  • From October 1st to present, there have been an estimated 9.8 million to 11.4 million flu illnesses
  • A total of 22 flu-related pediatric deaths have been reported
  • As of mid-January, flu vaccination coverage in children ages 6 months to 17 years was 45.6%, an increase of 6.8% from last time this year
  • Flu vaccination coverage in adults is 44.9%, up 6.4% compared to last year at this time
  • Influenza A (H1N1) is currently the most common strain of the flu in the U.S., which is protected by the vaccine
  • The H3N2 strain, predominantly found in the southeast, is also covered by the vaccine
  • Flu rates typically peak between December and February
