A rare skin disease has killed scores in Vietnam.
Vietnam now plans to ask for international help to find out what is causing a skin infection that has already killed 19 people.
More than 170 people in the country’s central province of Quang Ngai have reported symptoms.
The disease begins with a rash on the hands and feet: it can progress to liver problems and multiple organ failure.
Vietnamese health ministry tests have failed to pinpoint the cause of the unusual illness.
