Health authorities in Hamburg announced on Thursday that two people who returned from Rwanda had tested negative for the Marburg virus.
The tests were carried out at a hospital in the Hamburg-Eppendorf district, according to the press release.
Two of those tested returned from Rwanda on Wednesday.
They traveled together by train from Frankfurt to Hamburg. During that trip, one of them, fearing that he had contracted a tropical disease, contacted the doctors. He worked in a hospital in Rwanda as part of his medical studies where patients infected with the Marburg virus were treated.
According to German media, it is a young man in his twenties who developed flu-like symptoms.
But he never had symptoms that would correspond to infection with the Marburg virus, the authorities specified.
The medical student will be kept under observation until the end of the incubation period, which can last up to 21 days, according to authorities.
Another person, who had never been around anyone with the disease, also tested negative and had mild symptoms of another disease, according to authorities.
“Any risk for third parties is thereby excluded,” according to the press release.
An outbreak of the Marburg virus recently broke out in Rwanda. As of September 27, 29 cases were confirmed, and 11 people died.
The Marburg virus causes high fever and internal bleeding, and the death rate is up to 88 percent. The disease is similar to Ebola.
