Ones who survive Ebola may suffer potentially blinding vision problems, hearing loss and joint pain for months afterwards, medical experts reported on Wednesday, writes Daily Mail.

US Centers for Disease Control and Prevention says, many of these survivors suffer from persistent medical conditions after recovery from Ebola, including joint pain, eye problems, headaches, and other chronic health issues. In addition to these complications, scientists know that Ebola virus can stay in certain body fluids even after recovery, including semen, ocular fluid in the eye, breast milk, and spinal column fluid.

Recovery from Ebola depends on good supportive care and the patient’s immune response. Evidence from previous Ebola outbreaks shows that people who survived the disease had antibodies to the virus that could still be detected 10 years after recovery.

According to TechTimes, in a report featured in the New England Journal of Medicine, Dr. Tim Uyeki and his colleagues from the CDC’s Ebola response team found that patients who recovered from the infection still suffered from at least one chronic health problem for several months following their discharge from the hospital.

Ebola survivors reported having problems with their senses and even their moods. Some patients also said they had issues with hearing loss and blurry vision.

Dr. Uyeki and his team discovered that the most common symptoms the Ebola survivors had after their release from the hospital were hair loss, lethargy and joint pain. Six of the participants said they experienced each of these indicators.

The research also showed that five of the survivors had blurry vision, five had insomnia, four had heart palpitations, four had anxiety or depression, three had burning sensations in their skin, three had shortness of breath, three had muscle pain, two had inflamed eyes and one had hearing loss.

Dr. Lee Norman, an expert on Ebola infection at the University of Kansas Hospital said it was not surprising to find out that survivors experienced chronic symptoms even after they recover from the infection.

He said that the CDC study, however, provides them with valuable information that they can use to determine the range of symptoms that patients may suffer from.
