Tanzania is facing an influx of Burundians escaping political unrest in their home country.
In a statement WHO said the flow of Burundians into Tanzania especially into its western village of Kagunga is threatening the receiving country’s health infrastructure.
According to the statement, between 500 and 2,000 Burundians are entering Tanzania every day.
The UN agency said cases of acute diarrhea and cholera have been confirmed among the refugees in Tanzania, particularly in the Kigoma border region.
Clashes erupted in Burundi in late April after President Pierre Nkurunziza launched a bid for a third consecutive term in office.
