Guatemala
Risk:
High
Health Overview
Guatemala is home to extraordinary travel experiences — Antigua's UNESCO World Heritage colonial architecture; the volcanic landscape of Lake Atitlán; the Mayan ruins of Tikal in Petén; and the living indigenous cultures of the Western Highlands — but it carries a Level 3 State Department advisory with four Level 4 Do Not Travel sub-zones added following the terrorism risk indicator designation in 2025. The pre-travel health consultation is genuinely complex: dengue reached record highs in 2024 and is now spreading into Antigua and Guatemala City; malaria requires prophylaxis in only 5 specific departments; an active New World Screwworm Myiasis CDC THN names Guatemala specifically; Chagas disease is endemic in rural communities; and the security picture requires geographic precision. The critical differentiator between a well-prepared and underprepared traveler in Guatemala is knowing exactly which risk applies to which region.
Key Health Risks
High
Dengue
Guatemala recorded the highest dengue case counts in its history in 2024. Dengue is year-round; highest risk in lower-altitude departments (Petén; Escuintla; Baja Verapaz; Santa Rosa; Zacapa). The most clinically significant update: dengue cases are now increasingly documented in Antigua (Sacatepéquez) and Guatemala City — areas not historically associated with high dengue burden. CDC Yellow Book Guatemala chapter specifically names this trend. Aedes aegypti mosquitoes bite during the day — DEET 20%+ must be applied throughout all outdoor activities; not just evenings. No dengue vaccine available for most travelers. Clinical presentation: sudden high fever; severe headache; retro-orbital pain; severe myalgia and arthralgia (breakbone fever); rash. Any febrile returning traveler from Guatemala requires dengue NS1 antigen or PCR testing.
High
Violent Crime and Terrorism
Guatemala Level 3 overall advisory with terrorism risk indicator added in 2025. Level 4 Do Not Travel zones: San Marcos Department; Huehuetenango Department; Zone 18 in Guatemala City; and the city of Villa Nueva — cartel; gang; and criminal organization violence including use of automatic weapons and RPG-grade weapons documented (RPGs used in Sololá Department December 2025). US government employees cannot travel to these areas. In tourist-frequented areas (Antigua; Lake Atitlán; Tikal; Quetzaltenango): ASISTUR tourist police (DISETUR) provide dedicated security — contact ASISTUR 24/7 at +502-2290-2810 or WhatsApp +502-5188-1819. Never use white taxis or chicken buses — use only radio taxis or app-based transportation endorsed by accommodations.
Low-Moderate
Chagas Disease
Chagas disease (Trypanosoma cruzi; transmitted by triatomine 'kissing bug' feces contaminating bite sites or mucous membranes) is endemic throughout Guatemala including rural highland communities. Risk is primarily for travelers sleeping in traditional adobe or thatch-roof structures where triatomine bugs nest in wall cracks. Acute phase (if recognized): Romaña's sign (unilateral painless periorbital edema at inoculation site) and flu-like illness. Chronic Chagas disease develops years later — cardiomyopathy; GI dysmotility — affecting approximately 30% of the chronically infected. Any missionary; community health worker; or traveler doing rural overnight stays in village settings should use bed nets; permethrin-treated sleeping surfaces; and avoid sleeping in cracked-wall traditional structures.
Health Risk Callout
The New World Screwworm THN is the active alert most likely to be missed by general practitioners preparing Guatemala-bound travelers. Cochliomyia hominivorax is a blowfly whose larvae infest living tissue of warm-blooded animals including humans. Any open wound in Guatemala — no matter how minor — should be kept covered with a bandage at all times throughout the trip. Any wound that is worsening rather than improving; that has unusual discharge; or that produces a sensation of movement inside the wound requires immediate medical evaluation and wound inspection for larvae. Debridement must be done under clinical supervision.
Other Health Risks
New World Screwworm Myiasis (active CDC THN — Guatemala specifically named; Cochliomyia hominivorax larvae infest open wounds in living tissue; keep ALL wounds covered with bandages at all times in Guatemala; any wound worsening rather than improving; or with sensation of movement; requires immediate medical evaluation); Typhoid (foodborne — moderate risk beyond tourist restaurant infrastructure); Travelers' diarrhea (moderate-high risk; azithromycin self-treatment kit recommended); Altitude illness (Quetzaltenango at 2335m; Chichicastenango at 2030m; some hiking routes exceed 3500m — basic altitude counseling for any extended highland trekking) | 2026 UPDATE: New World Screwworm: Outbreak has advanced into northern Mexico; CDC HAN issued; larvae remain a wound-infestation risk in Central America incl. Guatemala. (https://www.cdc.gov/han/php/notices/han00526.html, 2026) ; Dengue: PAHO grade-3 multi-country dengue outbreak ongoing across the Americas; Guatemala 2024 record levels persist. (https://www.paho.org/en/topics/dengue/dengue-multi-country-grade-3-outbreak, 2026)
Regional Information
Regional Risk Callout
Guatemala's risk profile divides sharply by geography. Guatemala City: the capital has excellent private hospitals (Herrera Llerandi; Centro Médico) in safe zones 10-16; however Zone 18 and Villa Nueva are absolute Level 4 Do Not Travel zones under any circumstances. Antigua (Sacatepéquez): the most-visited tourist destination — ASISTUR tourist police and DISETUR presence; no malaria risk; dengue risk increasing; best medical access outside Guatemala City. Lake Atitlán (Sololá): generally well-patrolled with ASISTUR presence; no malaria risk; dengue prevention needed. Tikal (Petén): Level 3 overall; malaria prophylaxis recommended for this department; licensed tour operators are the standard. San Marcos and Huehuetenango Departments: Level 4 Do Not Travel — cartel and gang terrorism; US government employees prohibited. Pacific coast lowlands (Escuintla): malaria risk present — prophylaxis recommended for travel to this department.
Regional Healthcare Callout
Guatemala City's Zones 10-16 area has private hospitals approaching international standards — Herrera Llerandi and Centro Médico are the primary recommendations. Outside Guatemala City: Antigua has limited clinics adequate for minor issues; Quetzaltenango has Hospital La Democracia. Tikal: nearest adequate care is Flores (Petén); serious emergencies require air evacuation to Guatemala City. ASISTUR (+502-2290-2810) can assist with emergency medical referral and transportation. US Embassy Guatemala City: +502-2354-0000.
Vaccine and Malaria Prevention
💉 Entry Vaccine Required
Yellow fever vaccine required at the border for travelers ≥1 year old arriving from countries with risk for YF virus transmission — including transits >12 hours through YF-endemic countries. Yellow fever is NOT a risk in Guatemala itself and CDC does not recommend YF vaccine for Guatemala travel; this is a border entry requirement only for those arriving from YF-endemic regions.
🛡️ Recommended Vaccines
CDC recommends Routine vaccines up to date (MMR; Tdap; influenza; COVID-19); Hepatitis A (strongly recommended — enteric disease burden is significant beyond tourist restaurant environments); Hepatitis B (recommended for all travelers not previously vaccinated); Typhoid (recommended — foodborne risk throughout the country); Malaria prophylaxis for travelers to the 5 high-risk departments only (Alta Verapaz; Baja Verapaz; Escuintla; Izabal; Petén — NOT needed for Antigua; Guatemala City; Lake Atitlán; or most tourist areas); Rabies pre-exposure series (consider for ecotourism; prolonged rural stays; wildlife contact; missions in rural communities). Be sure to consult your Dr. prior to travel to discuss.
🦟 Malaria Information
- Risk Level: Low
- Areas: Malaria prophylaxis recommended ONLY for the departments of Alta Verapaz; Baja Verapaz; Escuintla; Izabal; and Petén. No prophylaxis needed for: Antigua (Sacatepéquez); Guatemala City; Lake Atitlán (Sololá); Quetzaltenango; or most of the Western Highlands. Other departments with sporadic reported cases: mosquito avoidance precautions only (no chemoprophylaxis).
- Recommended Drug: Atovaquone-proguanil; chloroquine; doxycycline; mefloquine; primaquine (G6PD test required before prescribing); tafenoquine (G6PD test required before prescribing)
- Drug Resistance: No
Guatemala malaria is predominantly P. vivax (99%) with rare P. falciparum (1%). Crucially: both species are chloroquine-sensitive — Guatemala is west of the Panama Canal where chloroquine-resistant P. falciparum has not been documented. Chloroquine is therefore an effective prophylaxis option alongside atovaquone-proguanil; doxycycline; and mefloquine. The essential geographic teaching point: Antigua; Guatemala City; and Lake Atitlán are NOT malaria risk zones — prophylaxis is indicated only for the 5 named departments. The 2024 record dengue situation means mosquito avoidance via DEET is mandatory at ALL Guatemala destinations regardless of malaria risk. Be sure to consult your Dr. prior to travel to discuss.

Physician Note
Dr. Robert
Emergency Medicine · 25+ Years · 40+ Countries
Guatemala generates some of the most clinically layered pre-travel consultations in Central America. The malaria geography is the key teaching point — prophylaxis is only indicated for the five named departments: Alta Verapaz; Baja Verapaz; Escuintla; Izabal; and Petén. Travelers to Antigua; Guatemala City; and Lake Atitlán specifically do not need malaria prophylaxis.
This distinction matters because prophylaxis tends to be either over-prescribed for everyone or missed entirely. The dengue picture has changed — 2024 was a record high year nationally and cases are now emerging from Antigua and Guatemala City in numbers not seen previously. DEET all day; not just evenings; is the standard for every Guatemala-bound patient.
The New World Screwworm THN adds a clinical point that most general practitioners won't raise unprompted: any open wound must be kept covered throughout Guatemala; any wound that is worsening rather than improving requires wound inspection for larvae. Chagas disease is the rural overnight stay conversation — anyone doing community development or mission work in traditional highland or lowland villages should understand triatomine exposure and recognize the Romaña's sign. The security briefing is non-negotiable at Level 3 with the terrorism indicator — I specifically review the Level 4 sub-zones with every patient.

Notes
Special Evacuation Notes
Medical evacuation from Guatemala City is logistically feasible — direct flights to Houston; Miami; and other US cities. From Tikal or remote Petén: charter flight to Guatemala City is the first step. Travel insurance with air evacuation coverage is strongly recommended. ASISTUR (+502-2290-2810) is the first call for tourist emergencies — they coordinate with medical services and arrange secure transportation faster than standard emergency channels.
Safety Notes
Guatemala Level 3 with terrorism indicator added 2025. Do Not Travel absolutely: San Marcos; Huehuetenango; Zone 18 Guatemala City; Villa Nueva — cartel and gang terrorism documented. For the established tourist circuit (Antigua; Lake Atitlán; Tikal; Quetzaltenango): ASISTUR and DISETUR tourist police provide dedicated security — register with ASISTUR and contact them at +502-2290-2810 (24/7; English-speaking) immediately upon any security incident. Never use white taxis or chicken buses — use only radio taxis or app-based rides confirmed through your accommodation. Avoid driving outside Guatemala City at night. Keep ASISTUR contact programmed before arrival — they respond faster than standard emergency services for tourist incidents. Check CONRED (conred.gob.gt) for current volcano alert levels before any volcano hike.
