A new drug that can kill the flu virus in just one day wins regulatory approval in Japan.

The drug, Xofluza, could soon be a competitor to Tamiflu.

However, it could take until at least 2019 for it to reach the U.S. market.

The Japanese drug-maker Shionogi said one dose of Xofluza kills the virus within 24 hours.

The new drug comes as the U.S. experiences its worst flu outbreak in 15 years.
