　　Scientists from the Commonwealth Institute of Science and Industry in Australia say that the immune system of bats may be the secret of humans' fight against Ebola. Although the origin of the Ebola virus cannot be completely determined, most scientists believe that African fruit bats may be one of its origins.

　　Australian Commonwealth Institute of Science and Industry (CSIRO) Dr. Michel Baker (Michel Baker) said that bats carry a large number of Ebola virus, but did not show any symptoms of disease, because the immune system has been activated and has been Has been activated. Will overwork and become able to resist the virus. Baker said that the human problem is that the body can activate the immune system only after the virus invades, but it is too late. The damage caused by the Ebola virus has become so severe that the immune system cannot resist.

　　She said that another problem is that bats can tolerate overload of their immune systems, while humans cannot. When the immune system becomes very sensitive to fighting the virus, the harm it does to the human body outweighs the benefits. In fact, symptoms such as fever, internal and external bleeding in Ebola virus patients are the result of an overreaction of the immune system. Although it is now known that bats can resist the Ebola virus, Baker said that there is still a long way to go before the human immune system can function like bats without causing side effects.

　　Scientists now believe that the Ebola virus is transmitted to primates through African fruit bats and then to humans. This is because many parts of West Africa still rely on primates for their livelihoods.
