Bangladesh
Risk:
High
Health Overview
Bangladesh is a Level 3 Reconsider Travel destination — the risk indicators are kidnapping; unrest; crime; and terrorism. Political unrest decreased significantly after the summer 2024 political transition and formation of the Interim Government; however protests continue with potential for rapid violence escalation. Clinically; the pre-travel consultation is substantive: Bangladesh has an active Global Dengue THN with Bangladesh specifically named (February 2026 update); an ongoing outbreak of extensively drug-resistant (XDR) typhoid fever where only azithromycin and carbapenems remain reliably effective; air quality in Dhaka that consistently ranks among the world's worst (AQI regularly 200-400+); malaria in the Chittagong Hill Tracts; and healthcare below Western standards throughout. Dhaka's population density and infrastructure create a complex environment where standard food and water precautions are mandatory throughout. Be sure to consult your Dr. prior to travel to discuss.
Key Health Risks
High
XDR Typhoid Fever — Ongoing Outbreak
Bangladesh has an ongoing outbreak of extensively drug-resistant (XDR) typhoid fever — Salmonella Typhi H58 strain — first emerged in South Asia. The CDC Travel Health Notice (XDR Typhoid) was originally posted for Pakistan but the same H58 strain circulates in Bangladesh. XDR typhoid is resistant to ampicillin; chloramphenicol; trimethoprim-sulfamethoxazole; fluoroquinolones; AND third-generation cephalosporins. Only azithromycin and carbapenems remain reliably effective. Clinical implications: (1) The typhoid vaccine (Vi polysaccharide or Ty21a oral) provides partial protection but does NOT cover XDR strains fully; (2) Returning travelers with fever who were in Bangladesh need prompt blood culture if typhoid is suspected — do not empirically treat with fluoroquinolones or cephalosporins for suspected XDR typhoid; (3) Recommend travelers carry a prescription for azithromycin as a self-treatment option for febrile illness where typhoid is on the differential. Be sure to consult your Dr. prior to travel to discuss.
High
Dengue — Active THN
Bangladesh is specifically named in the CDC Global Dengue Travel Health Notice (updated February 17 2026; updated again March 23 2026). Dengue is a year-round risk in Bangladesh with outbreaks commonly occurring every 2-5 years; Bangladesh experienced a record dengue outbreak in 2023 with over 300000 cases and hundreds of deaths. Dengue serotypes DENV-1 through DENV-4 all circulate. Risk is highest in Dhaka and other urban centers during and after monsoon season (June-October) but transmission occurs year-round. Severe dengue (dengue hemorrhagic fever; dengue shock syndrome) is a documented complication particularly in patients with prior exposure to a different serotype. No vaccine available for use in naive adult US travelers (Dengvaxia only for those with prior dengue exposure and confirmed seropositivity). Prevention: DEET 30%+ on all exposed skin; permethrin-treated clothing; Aedes aegypti bites during daylight hours — daytime mosquito protection is essential. Be sure to consult your Dr. prior to travel to discuss.
Moderate-High
Air Quality and Environmental Health — Dhaka
Dhaka's air quality is consistently among the world's worst — AQI regularly exceeds 200 (Very Unhealthy) and reaches 300-400+ (Hazardous) during winter months (November-February) when temperature inversions trap particulate matter. PM2.5 concentrations in Dhaka are approximately 15-20x WHO safe levels during peak pollution periods. Clinical implications for travelers: (1) Patients with asthma; COPD; cardiovascular disease; or other respiratory conditions face genuine clinical risk and should discuss the air quality risk with their physician before any Dhaka travel; (2) All travelers should carry an N95 respirator — not a surgical mask — and use it consistently outdoors and in vehicles; (3) Air quality apps (IQAir; AirVisual) should be checked daily; (4) Children and older adults face elevated risk. Be sure to consult your Dr. prior to travel to discuss.
Health Risk Callout
Bangladesh's clinical consultation centers on two points that directly distinguish it from a generic South Asia discussion: XDR typhoid and Dhaka's air quality. The XDR typhoid story is critically important — patients may carry old prescriptions for ciprofloxacin as typhoid self-treatment that are now useless against the H58 strain; azithromycin is the drug to prescribe. The air quality point is not hypothetical: respiratory patients traveling to Dhaka in winter genuinely need to think carefully about whether the trip is advisable.
Other Health Risks
XDR Typhoid (ongoing outbreak; azithromycin or carbapenem only — fluoroquinolone and cephalosporin resistance); Leptospirosis (flooding; agricultural exposure); Rickettsia (scrub typhus in CHT); Tuberculosis (very high TB burden); Cyclones (Bay of Bengal coast — June-November peak season; Cox's Bazar and coastal areas are vulnerable; the Sundarbans delta is extremely exposed; follow Bangladesh Meteorological Department alerts) | 2026 UPDATE: Chikungunya: CDC Level 2 notice for Bangladesh (Dec 5, 2025); recirculation documented since 2024 in Dhaka. (https://wwwnc.cdc.gov/travel/notices, 2025-12-05) ; Zika: Zika cluster detected in Dhaka (2024) alongside ongoing dengue/chikungunya.

Regional Information
Regional Risk Callout
Bangladesh's health and safety risk profile varies by region. Dhaka (capital; approximately 22 million population): best healthcare available in Bangladesh (some private Western-standard clinics); intense air pollution year-round; dengue risk throughout; no malaria; primary political unrest location. Chittagong (second city; port): dengue risk; no malaria; sea cyclone risk on Bay of Bengal coast. Chittagong Hill Tracts (CHT) — Rangamati; Khagrachari; Bandarban districts: the only malaria-endemic area in Bangladesh (P. vivax 95%; P. falciparum 5%); security concerns with ongoing ethnic group-military conflicts; Level 2 sub-zone per State Dept advisory. Cox's Bazar (world's longest natural beach; home to massive Rohingya refugee settlements): no malaria in the coastal area; humanitarian mission activity; dengue risk; cyclone risk. Sylhet (tea region; northeast): dengue risk; no malaria. Khulna and Sundarbans delta: cyclone and flooding risk; dengue; no malaria; excellent wildlife tourism when security allows.
Regional Healthcare Callout
Healthcare in Bangladesh is below Western standards throughout the country. In Dhaka: Square Hospital and United Hospital represent the best available care — competent for many acute conditions but with limitations for complex emergencies. Outside Dhaka: medical capability declines rapidly; the CHT has minimal healthcare infrastructure. Specialized care beyond what Dhaka private hospitals can provide requires air evacuation to Bangkok or Singapore. Comprehensive travel insurance with air medical evacuation coverage is essential.
Vaccine and Malaria Prevention
💉 Entry Vaccine Required
None — Bangladesh has no vaccine entry requirements for US travelers. Yellow fever vaccine is required for travelers ≥1 year arriving from countries with YF transmission risk (including transits >12 hours in YF-endemic country airports) — this is a FROM-endemic-country requirement; not a universal requirement.
🛡️ Recommended Vaccines
CDC recommends routine vaccines up to date (MMR; Tdap; influenza; COVID-19); Hepatitis A (strongly recommended — food and water safety throughout Bangladesh is compromised; Hepatitis A transmission is common); Hepatitis B (recommended for extended stays or any potential medical or dental exposure); Typhoid (recommended — and critically important: inform patients about the ongoing XDR typhoid outbreak in Bangladesh; typhoid vaccine provides partial protection but does NOT reliably protect against XDR strains — azithromycin self-treatment availability is essential); Malaria prophylaxis for CHT travelers only (atovaquone-proguanil; doxycycline; mefloquine; or tafenoquine — individualized based on patient factors); Rabies pre-exposure series (consider for extended stays; rural travel; or any work involving animal contact) Be sure to consult your Dr. prior to travel to discuss.
🦟 Malaria Information
- Risk Level: Low
- Areas: Malaria exists ONLY in the Chittagong Hill Tracts (CHT) — Rangamati; Khagrachari; and Bandarban districts. No malaria risk in Dhaka; Chittagong city; Cox's Bazar; Sylhet; Khulna; or anywhere else in Bangladesh. CHT species: P. vivax (approximately 95%); P. falciparum (approximately 5%); P. malariae and P. knowlesi (rare).
- Recommended Drug: Atovaquone-proguanil; Doxycycline; Mefloquine; or Tafenoquine for CHT travelers. Chloroquine not recommended in the CHT due to documented P. falciparum chloroquine resistance. For travelers not visiting CHT: no malaria prophylaxis needed.
- Drug Resistance: No
Malaria in Bangladesh is geographically confined to the Chittagong Hill Tracts — do not prescribe prophylaxis for travelers staying only in Dhaka; Chittagong city; Cox's Bazar; or other non-CHT destinations. For CHT travelers: prophylaxis is indicated; atovaquone-proguanil (Malarone) is a good first-line choice. For missionaries or extended CHT workers: longer-term prophylaxis choices (doxycycline or mefloquine) may be preferable based on duration and patient factors.

Physician Note
Dr. Robert
Emergency Medicine · 25+ Years · 40+ Countries
Bangladesh is a destination where I spend real time in the clinical consultation — not because the vaccine list is long but because of two specific and important drug resistance topics. First: XDR typhoid. The H58 strain is resistant to fluoroquinolones and third-generation cephalosporins — most of the antibiotics we would have empirically used for typhoid a decade ago.
I write every Bangladesh-bound patient an azithromycin prescription for self-treatment and I explain specifically: 'If you develop a fever in Bangladesh or in the weeks after return; seek medical care; do not self-treat with your old cipro prescription — it won't work for XDR typhoid.' Second: the air quality conversation for Dhaka. AQI regularly above 200-300 in winter is a clinical fact that matters for any patient with asthma; COPD; or cardiac disease — this is not a footnote; it is a genuine pre-travel risk discussion for those patients. Be sure to consult your Dr.
prior to travel to discuss.

Notes
Special Evacuation Notes
Air medical evacuation to Bangkok (approximately 3 hours) is the standard routing for emergencies beyond Bangladesh private hospital capability. Travel insurance with air medical evacuation is essential. US Embassy Dhaka maintains air ambulance provider contacts. Note: US Embassy Dhaka is closed Fridays and Saturdays (Bangladeshi and Islamic weekend schedule — open Sunday through Thursday).
Safety Notes
Bangladesh is a Level 3 Reconsider Travel country — the security picture has improved since the summer 2024 political transition but the situation remains fluid and can deteriorate rapidly. Key safety guidance: (1) Protests and demonstrations: avoid all gatherings even those that appear peaceful — they can turn violent rapidly with little warning per the State Dept advisory; (2) Dhaka traffic: one of the world's most dangerous road environments — use only reputable hired vehicles with seatbelts; avoid rickshaws for city travel; (3) Chittagong Hill Tracts: heightened security risk from ongoing ethnic violence; permit required for foreigners to visit certain CHT areas; consult current US Embassy alerts; (4) Terrorism: Bangladesh has experienced Islamist terrorist attacks targeting foreigners and secular Bangladeshis; the July 2016 Holey Artisan Bakery attack in Dhaka killed 22 people including 7 Japanese; remain vigilant at hotels; restaurants; and venues frequented by foreigners; (5) Kidnapping risk: noted in the State Dept Level 3 indicators. Be sure to consult your Dr. prior to travel to discuss.
