The American patient being treated for Ebola is improving, according to the National Institutes of Health (NIH).
The NIH announced on Thursday that the patient has had her condition upgraded from critical to serious. The patient, who was working to combat Ebola in Sierra Leone, arrived at the NIH in Bethesda, Md. on March 13 for treatment.
The patient is one of 17 volunteers for Partners in Health who were brought to the United States for precautionary monitoring. The NIH has not released any further details about the patient.
The American patient is the second to be treated by the NIH for Ebola. The team also treated Dallas nurse Nina Pham who was infected after treating Thomas Eric Duncan, the first person to be diagnosed with Ebola in the United States.
The current Ebola outbreak reached one year this week. So far 24,927 people have been infected and 10,338 people have died from the disease.
