Healthcare facilities in Papua New Guinea are poor by Western standards. Make sure you have comprehensive travel insurance that will cover all possible medical costs, including medical repatriation. Malaria is a problem throughout PNG, including in Port Moresby, although the risk to short-term city visitors is low. Dengue fever can also occur in the city. Water supplies can be interrupted or polluted, and cholera and influenza outbreaks have happened in recent years. Observe strict hygiene precautions and only drink bottled, chlorinated, or boiled water. Avoid ice and undercooked food. When traveling to PNG, vaccinations are recommended for Diphtheria and Tetanus, Hepatitis A, Hepatitis B, and Typhoid fever.
