Area of Science:

• Travel Medicine
• Preventive Medicine
• Public Health

Background:

• Millions travel internationally each year, with a substantial portion visiting developing countries or rural areas.
• While major travel-related medical risks are often overstated, minor illnesses are common, affecting 65-75% of travelers on month-long trips to regions like Asia, Africa, or Latin America.
