New drug for recurring malaria
A new drug to treat malaria has been given the green light by authorities in the United States.
The medicine is specifically for the recurring form of malaria - caused by the parasite plasmodium vivax- which makes 8.5 million people ill each year.
This type of malaria is a particular challenge to get rid of as it can remain dormant in the liver for years before reawakening many times.
Scientists have described tafenoquine as a "phenomenal achievement."
