A travel warning has been issued with an outbreak of a highly contagious virus similar to Ebola . Rwanda says eight people have died so far from Marburg virus, just days after the country declared an outbreak of the deadly hemorrhagic fever that has no authorized vaccine or treatment. So far 26 cases have been confirmed.

Based on the current risk assessment, WHO advises against any travel and trade restrictions with Rwanda. Like Ebola, the Marburg virus originates in fruit bats and spreads between people through close contact with the bodily fluids of infected individuals or with surfaces, such as contaminated bed sheets. Without treatment, Marburg can be fatal in up to 88% of people who fall ill with the disease.

Rwanda, a landlocked country in central Africa, declared an outbreak on Friday and a day later the first six deaths were reported. The public has been urged to avoid physical contact to help curb the spread. Some 300 people who came into contact with those confirmed to have the virus have also been identified, and an unspecified number of them have been put in isolation facilities.

Most of the affected are healthcare workers across six out of 30 districts in the country. “Marburg is a rare disease," Nsanzimana told journalists. “We are intensifying contact tracing and testing to help stop the spread.

” A WHO spokesman said: “It is important for people showing Marburg-like symptoms to seek care early for supportive treatment which can improve patient survival..
