Guidance for Travelers:
International Travel & Infectious Disease
Many diseases are just a plane ride away. Take care of yourself and others before, during, and after travel with these resources and information.
Whether you are traveling outside the U.S. to visit friends and relatives, for vacation, or on business, don't let illness interfere with your activities. Contact your primary health care provider or a travel clinic at least 4 to 6 weeks before you travel to discuss your travel plans and allow time to obtain necessary vaccines and medications. If your trip is less than 4 weeks, you should still seek care before traveling. Some clinics have availability for last-minute travelers. Ask your health care provider:
- Do I need vaccines?
- Should I take medication to prevent malaria?
- Is there something I should do to prevent diarrhea or other health problems like blood clots when traveling?
- Are there other things I should consider to stay healthy and keep others around me safe?
Your provider will need to know your travel plans like destination(s), how long you will travel, any previous health issues, as well as your reasons for travel. Even if you are familiar with your destination, it is important to understand the current risks in order to be well prepared for the trip.
Travel medication can be expensive. There are several things you can do at the doctor's office, at the pharmacy, and at home to find more affordable travel medication. Tell your doctor that you are worried about the cost of medication, ask the pharmacist if they can give you a generic or if there are discount cards available, and call different pharmacies to ask how much the medicine will cost.

Cholera is an acute bacterial infection caused by ingested water or food contaminated with Vibrio cholerae. The risk of infection for travelers is quite low once they follow the appropriate sanitation measures. Most people infected by Vibrio cholerae do not show symptoms or present with mild diarrhea. People with low gastric acidity have an increased risk of developing severe illness. Infection is characterized by acute watery diarrhea described as "rice water stools" with associated nausea and vomiting. This causes severe dehydration quickly, hypovolemic shock, and death in a couple of hours if not treated promptly.
