Ebola is one of the most harmful viral diseases to human beings. In 1976, fatal haemorrhagic fever broke out in China and many parts of Africa for the first time, first in a commune near the Ebola River in the Democratic Republic of the Congo, and then again in Sudan, about 500 miles away. In fact, it is believed that these two infectious diseases are the same virus carried by travelers, but later genetic evaluation showed that this is caused by different strains of Ebola virus. Later, according to the research and mechanical records of the virus, Ebola virus had followed us for a long time before the two earliest recorded infections occurred. The spread of the virus may be due to the expansion of human population, the invasion of forest civilization and the strong interaction with wild animals. Since the first discovery of Ebola virus in 1976, we have seen several Ebola cases and incidents in Africa. From 2014 to 2016, the Ebola epidemic in West Africa started in rural Guinea, and the situation is more serious. The Ebola virus soon spread to the city and crossed the border within a few weeks. In recent months, the occurrence of infectious diseases is really an international crisis. In this incident, the health manpower accounted for 3.9% of Sierra Leone, Liberia and Guinea. In the initial incident of Kiquet in 1995, the medical manpower accounted for 25% of all infected people at that time. In 2014-2015, most of the transmission incidents occurred between close relatives, mainly in direct contact with the bodies of Ebola’s dead. In order to change mourning and funeral related behaviors and use safe burial procedures, public health intervention is of great significance to control the infectious disease.

When Ebola broke out for the first time in 1976, people made great efforts to determine the host and the transmission mechanism of the disease in order to use information to deal with emergencies. Researchers checked a large number of wild animals, insects and plants, found the source and reservoir, and found the source, which is very difficult. Because reservoir hosts carrying Ebola virus may not have any symptomatic diseases. Therefore, it will be preserved in the ecosystem until it is transmitted among hosts, through intermediate hosts or vectors, and finally manifested as an acute disease in humans. In fact, African fruit bats are almost involved in the transmission of Ebola virus, and may even be the animals of origin, but so far it has not been completely determined. At the beginning, the use of dirty needles and syringes can almost ensure the spread of Ebola virus. It is also reported that when the first infectious disease occurred in the Democratic Republic of the Congo in 1976, nurses in a teaching hospital only used five syringes to treat 300~600 patients every day. During early Ebola onset, any contact close to contaminated blood, recovery of contaminated needles, and improper nursing methods may become a source of infection among a large number of people. Given that people know too much about the risks associated with viral transmission and many health strategies, the risk is much smaller, and infectious diseases are usually immediately controlled.
