WHO: Consider using survivor blood treatment Ebola

Release date: 2014-08-20

With the escalation of the Ebola outbreak in West Africa, the World Health Organization (WHO), which is eager to find ways to help infected people, is considering a potential treatment that was tried in 1976: using the Ebola virus. Human blood treats those who are still fighting the disease. “The recovery phase sera are at the front end of our list of potential therapies and have been used in outbreaks of other diseases,” WHO said in a statement to Science. “This therapy has a long history, so for There is a lot of experience in what needs to be done and what standards and specifications need to be followed."

There is currently no official plan to manage the use of convalescent sera, but WHO said it will assess whether the therapy is “safe and feasible” and is working with officials in areas affected by the Ebola virus to strengthen local blood storage systems. These actions are also accompanied by researchers' debates about the mixed results of serum use in the past recovery period.

Daniel Bausch, an expert on Ebola virus at Tulane University, said that for this method, "there is no conclusion yet." Still, he and others believe that this therapy should be developed. “I feel that we have a moral obligation to advance all reasonable scientific methods,” Bausch said. He also said that the use of convalescent serum to treat Ebola virus infection is an attractive option.

According to the data, there were 2,127 cases of confirmed, suspected and possibly infected Ebola in West Africa, with 1,145 deaths. Recently, the WHO warned that these figures may "substantially underestimate the magnitude of the outbreak." This is the largest outbreak of the Ebola virus since its record, and the huge death toll has required trials of experimental therapies that are still in the early stages of development. Recently, an ethics committee of the WHO announced that it is ethical to use unapproved Ebola virus therapy such as ZMapp under special circumstances.

Ebola virus is one of the most lethal viruses discovered so far, and there is no effective treatment. The incubation period of Ebola virus ranges from 2 days to 21 days. Currently, the main channel for the infection of Ebola virus is that it is directly exposed to the blood, secretions and other body fluids of infected people, or to the bodies of dead infected people.
