The World Health Organisation has suggested Tanzania may be keeping its emerging Ebola crisis secret, even as the region struggles to contain an already declared outbreak. 

The WHO reports a woman who had been diagnosed with the disease, died on the 8thof September, and two further cases have been identified, but the limited available information from Tanzanian authorities represents a challenge for medical responders. 

Last week the US health secretary, Alex Azar criticised Tanzania for its failure to share information on the possible outbreak. The next day he dispatched a senior US health official to Tanzania.
