Iran Travel Health Guide for US Travelers
A physician-reviewed health and safety guide for Americans considering travel to the Islamic Republic of Iran
The U.S. Department of State advises Americans Do Not Travel to Iran due to the risk of terrorism, civil unrest, wrongful detention of US nationals, and the arbitrary enforcement of local laws. The Iranian government has a pattern of arresting and imprisoning US citizens — including dual nationals and journalists — on baseless charges. There is no US Embassy or Consulate in Iran. The US has no diplomatic representation in Iran and cannot provide routine or emergency consular services to US citizens. If you are in Iran, the State Department urges you to depart immediately. Always check travel.state.gov for the latest advisory.
Islamic Republic of Iran
Capital: Tehran | Region: Middle East | Language: Persian (Farsi)
Travel to Iran — Critical Warning for US Citizens
The US State Department's Level 4 "Do Not Travel" advisory to Iran is among the most serious issued for any country. Iran is home to extraordinary cultural heritage — Persepolis, Isfahan, Yazd, and the bazaars of Tabriz — but these attractions are entirely inaccessible to US citizens without accepting extreme personal risk. The Iranian government has arrested numerous US nationals on fabricated espionage and security charges, held them for years in Evin Prison, and used them as political bargaining chips. The following health information is provided for completeness and for the rare categories of travelers — such as dual nationals with compelling family circumstances — who may consider travel despite these warnings.
Visit a Travel Clinic
See a travel medicine physician before departure. Iran requires no special vaccinations for US travelers. Hepatitis A vaccination is recommended. Discuss your specific itinerary, particularly if visiting southeastern border regions.
Travel Insurance
US sanctions complicate insurance in Iran — many policies will not cover Iran travel. Find a specialist insurer explicitly covering Iran before travel. Medical evacuation from Iran to Turkey or the UAE may be necessary for serious conditions. Verify your policy covers this in advance.
Visa & Entry — Extremely Complex
US citizens cannot obtain a visa through a US-based Iranian Embassy (there is none). US passport holders must apply through the Iranian Interests Section in Washington DC (operated through Pakistan's Embassy) or obtain a visa through an Iranian consulate abroad. US citizens born in Iran or with Iranian heritage face especially heightened scrutiny and detention risk.
Pack a Medical Kit
Bring all prescription medications in original labeled containers — many Western medications are unavailable in Iran due to sanctions impacting pharmaceutical imports. Include ORS, basic first aid supplies, and water purification for travel to rural or border areas.
Water & Food Safety
Tap water is generally treated in major Iranian cities (Tehran, Isfahan, Shiraz) and is considered relatively safe, though bottled water is preferred. Food safety at established restaurants is generally reasonable. Exercise caution with street food and raw produce in rural areas.
Cash & Financial Access
US bank cards and credit cards do not work in Iran due to sanctions. US financial institutions are prohibited from processing transactions with Iran. Travelers must bring sufficient cash — euros, UAE dirhams, or Turkish lira are most useful for exchange. Plan your entire trip financially before departure — there is no financial backup mechanism.
Yellow Fever in Iran
Malaria in Iran
The vast majority of US travelers would not visit Sistan-Baluchestan — the most remote and undeveloped province of Iran, also assessed as having active security risks due to cross-border tribal and narcotics-related violence. For travel to Tehran, the historic triangle (Isfahan, Shiraz, Persepolis), or other major sites, no antimalarial medication is recommended. If planning unusual itineraries to the Afghan or Pakistani border areas, discuss prophylaxis with your physician.
Recommended Vaccines for Iran
No vaccinations are required for entry. The following are recommended by CDC and WHO.
Recommended for all travelers. Transmitted through contaminated food and water. Two-dose series provides long-term protection. Risk is moderate in Iran outside major cities.
Typhoid risk is present, particularly outside major cities and for those eating at local establishments. Recommended for travelers planning anything beyond a major hotel itinerary.
MMR, Tdap, Polio Booster, Influenza, COVID-19
Ensure all routine vaccinations are current. A one-time adult polio booster is recommended for Middle East travel. Annual flu shot recommended before all international travel.
Recommended especially for longer stays or those who may need medical care in Iran. Three-dose series. Healthcare quality and blood supply safety in Iran is variable — vaccination provides important protection.
Healthcare System in Iran
In Tehran
Tehran has Iran's best hospitals — including Milad Hospital, Shariati Hospital, and Imam Khomeini Hospital. While technically capable for many conditions, sanctions have impacted the availability of specialist equipment and certain medications. Private hospitals offer better service than public facilities. Farsi is the primary language — English-speaking physicians exist at major institutions.
Medication Availability
US sanctions have disrupted Iran's pharmaceutical imports. Many brand-name Western medications are unavailable. Generic equivalents may exist but quality control varies. Bring a full supply of all prescription medications — do not rely on obtaining them in Iran. Carry medications in original labeled containers with a physician's letter.
Medical Evacuation
For serious conditions, medical evacuation to Istanbul, Turkey (approximately 2.5 hours by air) or Dubai, UAE (approximately 1.5 hours) provides access to world-class care. This requires medical evacuation insurance that explicitly covers Iran — which many standard policies do not. Verify coverage before travel. Note that for US citizens, departure from Iran itself may be restricted.
Emergency Numbers in Iran
The United States has no Embassy, Consulate, or diplomatic representation in Iran. If you are arrested, detained, injured, or in distress in Iran, the US government has no direct ability to assist you. Swiss Embassy in Tehran represents US interests to a very limited extent — contact: +98 21 8800-4500. The State Department's 24-hour line (+1-888-407-4747) can attempt to coordinate assistance through third parties but options are severely limited. This is the most dangerous consular situation a US citizen can face.
Swiss Embassy (US Protecting Power)
No. 13, Yasaman Street, Sharifi Manesh Ave, Elahieh, Tehran
Phone: +98 21 8800-4500
Switzerland represents US interests in Iran but has very limited ability to assist detained US citizens. This is a last resort.
US State Dept 24/7 Hotline
From US/Canada: +1-888-407-4747
From abroad: +1-202-501-4444
Available 24 hours. Primary resource for US citizens in Iran — call immediately in any emergency.
STEP Enrollment
Register at step.state.gov before any travel to Iran. This is the primary mechanism by which the State Department may be aware of your presence and attempt to assist in an emergency — though options are extremely limited without Embassy presence.
Nature & Weather Risks
Extreme Heat & Dust
Iran's deserts (Dasht-e Kavir, Dasht-e Lut) experience extreme heat — temperatures in Lut Desert can exceed 70°C (158°F) surface temperature, among the hottest on Earth. Summer travel to desert regions requires exceptional preparation. Dust storms are common April–September. Stay hydrated and avoid outdoor activity during peak heat.
Earthquakes
Iran is one of the world's most seismically active countries — devastating earthquakes have killed tens of thousands in recent decades (Bam 2003, Kermanshah 2017). Know evacuation procedures at your accommodation. In an earthquake, drop, cover, hold on, and move away from windows. Do not use elevators after shaking stops.
Avalanche & Mountain Risks
Iran has significant mountain ranges — the Alborz (including Mount Damavand, 5,610m, the highest peak in the Middle East) and the Zagros. Mountaineering and ski tourism attract visitors. Avalanche risk is significant in winter/spring. Altitude sickness occurs above 3,000m. Always hike and ski with qualified local guides.
Road Safety
Iran has one of the world's highest road fatality rates. Driving is aggressive and often disregards traffic laws. Highways between cities are generally in good condition but dangerous due to driver behavior. Avoid road travel after dark. Wearing seatbelts is mandatory. Intercity buses are a safer alternative to private cars.
Crime, Violence & Safety Risks
Wrongful Detention of US Citizens
Multiple US citizens have been arrested in Iran on baseless charges including espionage, threatening national security, and insulting Islamic values. Charges can stem from social media posts, photography, contact with Iranian dissidents, or simply being American. Detention can last months or years. Iran does not recognize dual nationality for those arrested — they are treated as Iranian citizens only.
Surveillance & Monitoring
Iran's intelligence services conduct extensive surveillance. Assume all internet activity, phone calls, and communications are monitored. Do not access VPNs openly (illegal in Iran). Do not photograph military or government infrastructure, religious sites without permission, unveiled women, or political events. Delete any sensitive photos before entry.
Legal Restrictions for US Citizens
Alcohol is illegal in Iran. Dress codes are strictly enforced — women must wear a hijab in public; men must not wear shorts in public. LGBTQ+ relationships are illegal and carry severe criminal penalties. Social interaction between unmarried men and women can be criminalized. US dollar transactions may trigger scrutiny. Criticizing the government or Supreme Leader is a criminal offense.
Regional Conflict Risk
Iran's borders with Iraq and Afghanistan carry significant conflict spillover risk. The border areas with Iraq (western Iran) and Afghanistan/Pakistan (eastern Iran / Sistan-Baluchestan) should be avoided. Regional military tensions between Iran, Israel, and the US can escalate rapidly — airspace and border closures have occurred without notice in recent years.
Other Health Risks in Iran
Leishmaniasis
Cutaneous leishmaniasis is endemic in many parts of Iran, particularly in provinces including Khuzestan, Khorasan, and Fars. Transmitted by sand fly bites, mainly at dusk and night. Causes chronic skin ulcers. Use DEET repellent, wear long sleeves and trousers at dusk, and use fine-mesh nets (sand flies pass through standard mosquito netting).
Moderate risk. Major cities have improving water and food safety. Rural and border areas carry higher risk. Stick to bottled water throughout, eat at established restaurants, and carry ORS and a standby antibiotic per your doctor.
Air Pollution
Tehran suffers from severe air pollution, particularly in winter, trapped by surrounding mountains. Air quality can reach hazardous levels. Travelers with respiratory or cardiovascular conditions should monitor AQI levels and carry adequate medication. N95 masks provide significant protection on high-pollution days.
MERS-CoV
Iran has proximity to the Arabian Peninsula where MERS-CoV cases occur. Avoid contact with camels and raw camel products. Practice strict hand hygiene. Seek medical care promptly for any respiratory illness and disclose your travel history. MERS risk for tourists is very low but exists in the regional context.
