Health
Use careful food and water habits; standards vary and rural/trekking settings raise risk. Mosquito-borne illnesses are important: CDC lists malaria risk throughout PNG below 2,000 m, plus dengue, Zika and Ross River virus, so use bite prevention. Plan for heat, UV, heavy rain/floodwater, and altitude/cool nights in the Highlands; medical care can be limited outside major towns.
Vaccinations
Consult a doctor or travel clinic at least a month before travel. Be up to date on routine vaccines, including MMR, polio, flu, varicella, Tdap, shingles as appropriate, and COVID-19. CDC recommends hepatitis A, hepatitis B and typhoid for PNG; polio vaccination/booster may be relevant because poliovirus has been identified in the past year. Discuss Japanese encephalitis for long stays/rural/outdoor travel, rabies pre-exposure for higher-risk animal exposure or remote travel, and malaria prevention medicines. Yellow-fever vaccine is not recommended for PNG itself, but a certificate is required for travelers age 1+ arriving from yellow-fever-risk countries, including >12-hour transits.
eSIM / connectivity
eSIM is available but not universally frictionless. Vodafone PNG officially offers eSIM for compatible phones/tablets, but says activation is done in person at retail/flagship outlets with ID and cannot be purchased before arrival. For local connectivity, check prepaid/mobile data from Vodafone PNG, Digicel PNG and Telikom/bmobile; coverage is best in towns and along main corridors, and can be patchy in islands, mountains and villages. No clear official tourist eSIM product was found; a physical local SIM may still be the simpler fallback.
