However, his semen tested positive for the virus. He had a medical clearance certificate from the Liberian government saying the had been treated and was confirmed negative from blood tests—that would deem him Ebola-free, according to the World Health Organization and Centers for Disease Control and Prevention (CDC). His blood also tested negative in India. Semen can test positive after clinical clearance for up to three months, according to the CDC.
