"An investigation team led by the Ministry of Health and supported by WHO and partners has deployed and is expected to reach the affected area in the coming days," Dr. Peter Salama, WHO Executive Director for Emergencies, said on Friday.

The WHO later tweeted the response teams should be arriving in Congo between Friday and Saturday.

Though Likati health district is located in a remote area, health officials said it is taking the outbreak seriously and working to contain it as quickly as possible. About 70 percent of Congo's population has little or no health care access, according to the U.S. Agenccy for International Development.

The virus first spread to humans through close contact with infected animals such as fruit bats and monkeys. If can spread quickly among people if its not contained and 90 percent of cases are fatal.

The first Ebola outbreak in Congo occurred in 1976, according to the WHO. Since then, there have been eight other outbreaks. The last recorded one in the country was in August 2014 in Boendi, during one of the biggest outbreak of the virus in West Africa. More than 11,000 died in Guinea, Liberia and Sierra Leone between 2014 and 2015.
