The International Spread of Diseases

Patients and patients do not stay in one area but travel to another county by airline or cruise and infect other passengers. When a patient gets on, sickness may spread by mild but fatal coughing or sneezing, and sickness may spread. New diseases can spread internationally through the trip, and if cruise ships and airlines indicate restrictions, you can prevent innocent people from dying from the outbreak. Most airlines, such as British Airways, have an authorized physician working in an airplane and treating a patient.

Together with the International Association of Infectious Diseases, the Imperial College of London, and the Health Map, the Health Center maps the International Infectious Diffusion Association (MRIIDS) in West Africa. This project has been piloted in Senegal and Sierra Leone and funded through the USAID Grand Challenge.

This epidemic first appeared in the forest area of ​​Guinea in December 2013 and is gradually spread to Sierra Leone and Liberia afterwards. The international community saw the disease devastated the three countries, destroyed the village, destroyed the whole family, and stagnated the economy. But initially, it rarely attracted people's attention. The international community is pleased to ignore this fact until the epidemic spreads and it can not be realized. But by then it is too late to avoid large-scale disasters.

The proportion of HIV / AIDS prevalent in infectious diseases in the 1980s, especially in Africa where this disease may have occurred. Several factors are the cause of this spread, including urbanization in Africa, long-distance travel, international travel, changes in sex, increased intravenous administration of drugs. According to the 2004 AIDS report in 2004, about 38 million people are infected with HIV every year, about 5 million people are infected with AIDS, and about 3 million people die from AID every year. Since 1981, about 20,000 people have died of this disease.

Diseases are less restricted due to the movement of people and things, diseases such as AIDS, malaria and tuberculosis spread rapidly all over the world. Through oversea air travel, infected people can bring illness to other places within 36 hours from almost anywhere in the world. "Mad cow disease" that occurred in several European countries is an example of how trade is promoting the spread of diseases. Malaria-mediated mosquitoes were found in the aircraft and fish and shellfish infected with V. cholerae were shipped from Latin America to Europe and the United States.
