Travel and Residence Outside the United States or Canada

Malaria is transmitted by the bite of mosquitoes found in certain countries, and may be transmitted to patients through blood transfusion. Blood donations are not tested for malaria because there is no sensitive blood test available for malaria.

Malaria transmission can occur through travel and residence in some areas. This exposure can sometimes defer donors from blood donation. If you have traveled and/or resided outside of the United States and Canada, your travel destinations will be reviewed during the screening process with trained collection staff.

If you have traveled or lived in a country with malaria-risk, we may require a waiting period before you can donate blood. This is because the disease can be transmitted a year later without symptoms. Potential donors who have visited and stayed overnight in a malarial area are deferred from giving blood for one year from the date of that stay.

Your donation is important to us; please fill out Travel worksheet with your travel details when you donate. You may print the Donor Travel Worksheet and bring it with you to help in the assessment of your travel. You can call 425-656-3077 to speak with Collection Review specialist about your travel if you need assistance.

Information for All Donors About AIDS

The FDA requires all donors be given information on AIDS each time they donate blood. Please read this information carefully, even if you are a frequent donor, as some of the details may have changed since the last time you donated. Thank you for your cooperation.

AIDS (Acquired Immune Deficiency Syndrome) is caused by HIV. HIV is spread mainly through sexual contact with an infected person OR by sharing needles or syringes used for injecting drugs.

HIV/AIDS Risk Behaviors and Symptoms


  • The signs and symptoms of “AIDS” include the following:Persons with clinical or laboratory evidence of AIDS virus infection.
