Not all U.S. medical insurance is valid outside the United States. Travelers have found supplemental medical insurance with specific overseas coverage, including provision for medical evacuation, to be useful. Crime, particularly against foreigners, appears to be on the increase in both urban and rural areas. Incidents include attempted rapes, muggings, vehicle thefts, and residential break-ins. Thieves on buses and trains may steal valuables from inattentive riders.
Visitors driving in game parks are at risk.
In recent years, there has been an increase in acts of armed banditry in parks and reserves frequented by tourists. A recent attack in Serengeti National Park resulted in the death of an American citizen. The Tanzanian government has taken steps to increase security in the national parks, albeit with limited results to date. Assaults in Zanzibar and along public beaches in Dar es Salaam are becoming common, and police, particularly in Zanzibar, are at times inattentive to the problem. Crime and hazardous road conditions make travel by night dangerous.
