Conclusion. Volunteers experience a range of health problems during and after their placement in the developing world. Our
study shows the importance of (1) predeparture health preparation of volunteers and (2) medical care and advice for volunteers.
This advice is also important for travelers in similar conditions such as those visiting relatives, long-term backpackers, and students
working in or traveling to developing countries. Further research is needed to help explain some of the findings and study ways of
preventing accidents and illness.
