Why are travel-related infectious diseases on the rise?
It is believed that increased global travel is the reason for the recent resurgence of many infectious diseases in the United States. The number of persons traveling internationally is increasing every year, and more persons are taking trips to remote parts of the world, which often have unfamiliar and exotic health problems with underdeveloped healthcare services. Many travelers are also unaware of potential hazards in different parts of the world and do not take the necessary precautions, such as obtaining necessary vaccines or preventive medicine. Many of the newly discovered infections have actually been in existence for a long time, but physicians have not seen them in areas where new outbreaks occur. With people’s ability today to travel anywhere in the world within 36 hours or less, formerly little-known infections are picked up and rapidly spread to areas where they previously did not exist.
