Before setting off on your trip, you should talk to your doctor or health care provider. Make sure to complete go over your health with your doctor before you leave. Pay close attention to your CD4 cell count. If it is below 200 cells/mm3 (a marker of severe immunodeficiency) you will need to be extremely careful of infection while you are traveling.
Be sure to tell your doctor where you will be traveling. They can tell you about common illnesses to watch out for in those locations and how to protect yourself. Your doctor will also be able to warn you of places that might be unsafe to visit for someone with HIV. Also ask your physician to share names of other doctors who treat HIV in the area you're visiting because this information can help you in case of emergency. This is especially important if you plan on staying at your destination for an extended length of time.
