Solomon Islands
Risk:
Moderate
Health Overview
Solomon Islands is Level 2 — Iron Bottom Sound (WWII naval graveyard); world-class wreck diving. P. vivax dominant (70%) — unusual; changes clinical management (terminal primaquine discussion). WWII UXO remains throughout. Measles vaccination ENTRY REQUIREMENT from specified countries. 2021 Honiara riots (ethnic tensions). US Embassy Honiara LIMITED.
Key Health Risks
High
Malaria (P. vivax dominant; P. falciparum)
P. vivax 70% dominant — clinically distinctive. Hypnozoite relapse risk weeks-months after return that standard prophylaxis doesn't address. Terminal primaquine discussion essential. P. falciparum 30% — standard acute severity. Both CQ-resistant.
Moderate
WWII Unexploded Ordnance (UXO)
Guadalcanal Campaign (1942-43) left extraordinary UXO. Specific areas: Hell's Point; ridges behind Honiara (Mt Austen; Bloody Ridge); New Georgia (Munda; Kennedy Island); Tulagi; Russell Islands. NEVER leave established paths. Never pick up/probe unknown metal objects.
Moderate
Civil Unrest
November 2021 Honiara riots (arson; looting targeting Chinatown; ethnic Guadalcanal-Malaita tensions; 4 deaths). Australian/PNG security deployed. Underlying tensions remain. Avoid demonstrations.
Health Risk Callout
P. vivax dominance (70%) + terminal primaquine discussion + UXO risk + measles entry requirement = one of most complex Pacific pre-travel consultations.
Other Health Risks
Melioidosis (Burkholderia pseudomallei; soil/water; wound care); Saltwater crocodiles (mangroves; river mouths — do not swim in murky coastal water); WWII UXO (see Health Risk 2) | 2026 UPDATE: Dengue: Ongoing dengue transmission tracked in WHO Western Pacific biweekly Dengue Situation Updates (No. 743/744, Apr 2026); no new CDC country-specific notice. (https://cdn.who.int/media/docs/default-source/wpro---documents/emergency/surveillance/dengue/dengue_biweekly_744_20260430.pdf, 2026-04-30)
Regional Information
Regional Risk Callout
Guadalcanal/Honiara (capital; NRH; UXO on ridges/Hell's Point; 2021 riots). Western Province/New Georgia (WWII wreck diving; Kennedy Island). Malaita (artificial stilt islands; Auki). Remote islands (Rennell; Temotu): no medical facilities; complete self-sufficiency required.
Regional Healthcare Callout
Outer islands: non-existent to basic. Serious conditions: Honiara first; then Brisbane. US Embassy Honiara limited — Port Moresby for full consular.
Vaccine and Malaria Prevention
💉 Entry Vaccine Required
MEASLES ENTRY REQUIREMENT: travelers from American Samoa; Samoa; Fiji; Tonga; Kiribati; Australia; NZ; PNG; Philippines must show MMR proof ≥3 weeks before arrival. US direct: not required but strongly recommended. YF from endemic countries.
🛡️ Recommended Vaccines
CDC recommends Routine (MMR — CRITICAL: Measles THN + entry requirement from listed countries; ≥3 weeks before); Hep A (strongly recommended); Hep B; Typhoid; Rabies PrEP (extended/outer island — PEP unavailable outside Honiara)
🦟 Malaria Information
- Risk Level: High
- Areas: All areas year-round; P. vivax 70%; P. falciparum 30%; P. ovale <1%
- Recommended Drug: Atovaquone-proguanil; doxycycline; mefloquine. Terminal primaquine for P. vivax (G6PD test required).
- Drug Resistance: Yes
P. vivax 70%; P. falciparum 30% — BOTH CQ-resistant. Unusual vivax dominance. Hypnozoites cause relapsing malaria months after return. Terminal primaquine (14 days; G6PD test) strongly recommended for ALL travelers. Chloroquine NOT appropriate.
Moderate
Physician Note
Dr. Robert
Emergency Medicine · 25+ Years · 40+ Countries
Solomon Islands: P. vivax dominant at 70% is genuinely unusual — changes clinical management. Terminal primaquine discussion specific to Solomons/PNG/Vanuatu.
Measles entry requirement from listed countries. UXO on Guadalcanal ridges: 'Staying on paths is not paranoia; it's the State Dept guidance.' Iron Bottom Sound diving is extraordinary. Be sure to consult your Dr.
