Purchase travel and evacuation insurance. Although many insurance plans may cover overseas trips, it is a good idea to get insurance specifically for your travels abroad. Often ordinary health insurance policies will not even cover you in Africa. If this is the case, you should really consider purchasing insurance through an agency that specializes in travel insurance. Either way, it is good to look into your options. There are low costs, good benefits policies offered by a number of agencies working with short term mission trips. One of the sources that we have used is associated with the National Association of Evangelicals. Their website address is http:www.missionaryinsurance.com/index.php/Insurance-Plans.html. Their prices are really good and coverage is good too. If you apply early they even include some limited dental insurance.
