Globalization processes such as: travel patterns, trade with technological developments and environment alterations have increased the spread of infectious diseases across the world. Today the travel patterns of people have increased, because of the efficient and inexpensive access to different modes of transportation. “In 2008, there were over 922 million international tourist arrivals…” according to Article: “Tourism” From Wikipedia, free encyclopedia online. This behavior causes people germs to transmit to other people in other countries, which also favor disease evolution because of the mutation and combination of these germs, causing stronger or new diseases. Another process will be the trade with technological developments, were technologies such as: ships, trucks and aircraft that move products, food, ect also facilitate the transfers of diseases from a place to another, because sometimes rats and other rodents are able to access such transportations and not only contaminate with germs some of the products, but also stay in some of the destinations. One example is the West Nile Virus, “ which it is believed that this disease reached the United States via mosquitoes that crossed the ocean by riding in airplane wheel wells and arrived in New York City in 1999”, according to article: “Globalization and disease” from Wikipedia. Last, but not less important will be the environment alterations such: deforestation and contamination, which causes some animals with their own diseases to migrate from a country to another, where sometimes these diseases are transmitted to humans. Certainly, globalization facilitate infectious diseases to spread easily, therefore, it should be a major concern both for the developing countries and developed countries.
