Kigali, RWANDA -- Rwanda says eight people have died so far from the Ebola-like and highly contagious Marburg virus, just days after the country declared an outbreak of the deadly hemorrhagic fever that has no authorized vaccine or treatment.
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. So far 26 cases have been confirmed, and eight of the sickened people have died, Health Minister Sabin Nsanzimana said on Sunday night.
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."
The minister said the source of the disease has not been determined yet. A person infected with the virus can take between 3 days and 3 weeks to show symptoms, he added. Symptoms include fever, muscle pains, diarrhea, vomiting, and, in some cases, death through extreme blood loss.
In a , the CDC said that no cases of Marburg virus disease related to the outbreak have been reported in the U.S. and that the anticipated risk to the general U.S. population is low.
The agency noted that it has had a longstanding presence in Rwanda and has offered additional support to deal with the Marburg virus disease outbreak.
"CDC is deploying subject matter experts to assist with the country's investigation and response to this outbreak," the agency said. "The staff will use experience from responding to outbreaks of Marburg virus disease and similar diseases in other countries to support epidemiology, contact tracing, laboratory testing, disease detection and control along borders, and hospital infection prevention and control."
The World Health Organization (WHO) was scaling up its support and will work with Rwandan authorities to help stop the spread as well, WHO's Director-General Tedros Adhanom Ghebreyesus, PhD, said on Saturday on the social media platform X.
The U.S. Embassy in Rwanda's capital of Kigali has urged its staff to work remotely and avoid visiting offices.
Marburg outbreaks and individual cases have in the past been recorded in Tanzania, Equatorial Guinea, Angola, Congo, Kenya, South Africa, Uganda, and Ghana, according to the WHO.
The rare virus was first identified in 1967 after it caused simultaneous outbreaks of disease in laboratories in Marburg, Germany, and Belgrade, Serbia. Seven people died who were exposed to the virus while conducting research on monkeys.
Separately, Rwanda has so far , a disease caused by a virus related to smallpox but that typically causes milder symptoms. Mpox, previously known as monkeypox because it was first seen in research monkeys, has also affected several other African countries in what the WHO has called a global health emergency.
Rwanda launched an mpox vaccination campaign earlier this month, and more vaccines are expected to arrive in the country. Neighboring , the epicenter of the emergency.
