A Nigerian nurse who aided a man with Ebola has died and five new cases of the deadly virus have been reported in the country.
Bloomberg News reported that health officials have said that the newly confirmed cases are in Lagos, which is Nigeria’s most populous city.
"It makes you nervous when so many people are potentially at risk," said David Morse, an epidemiology professor at Columbia University's Mailman School of Public Health.
The Associated Press noted that Patrick Sawyer was the patient the nurse treated. He was an American of Liberian descent and lived with his family in Minnesota. He had traveled to West Africa on a business trip and became ill. He died on July 25.
Ebola has been plaguing the African nations of Guinea, Sierra Leone, Liberia and Nigeria for the past several months. The often fatal disease has already claimed almost 900 lives.
The virus is spread through human contact and has also been found in primates.
The symptoms associated with Ebola are arthritis, chills, diarrhea, fatigue, fever, headache, nausea, vomiting and internal as well as external bleeding.
