Chuuk Lagoon Ghost Fleet (~60 Japanese warships; best WWII wreck diving in world). Crime significantly higher in Chuuk. Yap manta rays (Mil Channel — world's most reliable aggregation).

Key Health Risks
Moderate-High
Dengue (Endemic)
CDC classifies FSM as endemic — frequent/continuous risk (dark purple on Yellow Book map). All four serotypes have circulated. Multiple outbreaks documented. Aedes aegypti daytime biting. DEET 30%+ at all times.
Moderate
Crime Risk in Chuuk
State Dept: 'significantly elevated crime rates' in Chuuk. Assaults on US citizens documented. Weapons (machetes) used as intimidation outside city limits. Stay on public roads; limit night travel. Does NOT apply to Pohnpei/Yap/Kosrae.
High
Very Limited Healthcare
'Only basic medical care available; only on main islands.' Pohnpei State Hospital largest/best. Genesis Hospital (private; Pohnpei). Medevac to Guam USMH (~1 hour from Pohnpei) or Honolulu (~5-6 hours).
Health Risk Callout
Dengue endemic + Measles THN = two key preparation items. DEET discipline throughout day. Chuuk safety awareness for Ghost Fleet diving. Cash at all airports.
Other Health Risks
NCDs (diabetes/obesity epidemic — among highest in Pacific; consumes hospital capacity); Ciguatera (avoid large predatory reef fish)
Regional Information
Regional Risk Callout
Pohnpei (capital; US Embassy; best healthcare; Nan Madol; safest). Chuuk (Ghost Fleet diving; HIGHEST CRIME — assaults on US citizens; weapons outside city limits; limit night travel). Yap (stone money; manta rays; traditional culture). Kosrae (most isolated; deeply Christian; pristine reefs).
Regional Healthcare Callout
Basic on main islands. Outer islands: very limited. Guam is primary evacuation destination.

Physician Note
Dr. Robert
Emergency Medicine · 25+ Years · 40+ Countries
FSM: dengue endemic per CDC — not a THN but a structural classification. 'Aedes bite during the day; DEET from morning.' Confirm MMR. Chuuk Ghost Fleet is the most historically extraordinary wreck dive site in the world — but State Dept language about weapons outside city limits is specific and accurate.
Yap manta rays at Mil Channel: one of Pacific's most reliable wildlife encounters.
