Guidance for Relief Workers and Others Traveling to Haiti

  • If you anticipate giving medical care or working closely with ill or injured victims or other displaced persons in Haiti, a tuberculin skin test (TST) is recommended before travel and then 8-10 weeks after return. Depending upon availability, a TB blood test called interferon-gamma release assay or IGRA may be used in place of the TST. A negative result within the past 12 months should suffice as a baseline. Persons with prior positive results do not need to be tested again. If feasible, persons whose last negative TST result was >12 months before travel or who have no previous TST result should consider a two-step TST, as recommended for newly hired healthcare workers.

  • Regardless of TST or IGRA results, any person who develops symptoms of TB during or after deployment should seek a medical evaluation immediately.

  • If exposure to known TB patients or persons suspected of having TB will occur, traveling with personal respiratory protective devices (i.e., N-95 respirators), along with training, is recommended. The personal respiratory protective device should always be worn when in contact with any person suspected or known to have TB. Performing a user-seal check on respirators before each use is essential to ensure adequate respiratory protection. 

After You Come Home

A tuberculin skin test (TST) or TB blood test (interferon-gamma release assay or IGRA) is recommended 8-10 weeks after return.  Persons with prior positive results do not need to be tested again. 

  • If you did not have time to get a baseline TST or TB blood test before going to Haiti AND your last negative test result was >12 months prior or you had no previous result, consider getting tested as soon as possible after returning home, and then again 8-10 weeks after return. 

If you develop symptoms of TB disease, seek a medical evaluation immediately.  Tell your healthcare provider that you have recently returned from response and relief work in Haiti.  The risk of developing TB disease is highest in the first 2 years after infection.
