Tanzania is investigating an unknown illness in the south of the country that has killed three people.
In total 13 cases have been reported in Lindi region, with patients having symptoms similar to Ebola or Marburg.
They have been experiencing fever, severe headaches, fatigue and bleeding, especially from the nose.
But the health ministry says preliminary lab tests results rule out the Ebola and Marburg viruses in these cases.
Contact tracing was ongoing and five people were currently in isolation, it said.
Chief medical officer Dr Aifelo Sichalwe has urged Tanzanians to remain calm as investigations continue.
He further urged anyone exhibiting similar symptoms to immediately seek medical attention.
