Medical Conditions for Volunteers

Mercy Ships crew live and work in a very unique operational environment aboard a ship. Although we operate a hospital ship, the medical services available to crew have certain limitations due to potential lack of appropriate medical resources or supplies, lack of diagnostic or therapeutic equipment, or unavailable medications or treatments.

In order to help protect the health and safety of our crew, certain medical conditions may disqualify an individual for service aboard a Mercy Ships vessel. The demands of the environment as well as maritime medical regulations require all our volunteers to be in good physical and mental condition/fit for duty. As such, all applicants are required to complete a medical history and obtain a physical exam. In addition, all crew are required to obtain certain immunizations to comply with immigration and occupational health requirements prior to serving.

Currently, volunteers must be between 18 and 79 years old at the time of volunteer service. Applicants between 70-79 can serve for up to six months at a time and will be required to submit additional health documentation.


Certain medical conditions are always disqualifying, including (but not limited to) the following:

Bi-polar Disorder

Cardiovascular conditions (e.g., Cardiac transplants, pacemakers

Cystic Fibrosis

Insulin Dependent Diabetes

Need for Medication with Immune Suppression

Need for Medication for Chronic Anti-Coagulation

Organic nervous disease (e.g., Parkinson’s disease, multiple sclerosis) 

Recent History of Drug or Alcohol Abuse

Other medical conditions, depending on their severity, current treatment and your length of commitment may be disqualifying, including
(but not limited to) the following:



Chronic depression (unless successfully treated and on a stable medication regimen, if medications are required)

Cardiac conditions (e.g., coronary artery disease) 


Non-Insulin Diabetes

Severe Allergies

The final determination of an applicant’s medical fitness to serve is done on a case-by-case basis and may require the applicant to provide additional medical information.
