Iran
Travel Destination – Iran
Iran offers a deeply layered travel experience, where historic architecture, dramatic natural scenery, and modern urban life coexist. Travellers may explore the intricate mosques and gardens of Isfahan, the poetic heritage of Shiraz, and the bustling energy of Tehran, while also venturing into desert regions or alpine terrain in the Alborz and Zagros mountains.
From a travel medicine perspective, Iran represents a destination with generally developed healthcare infrastructure in major cities, but with variation in access and standards outside urban centres. Travellers should approach preparation with care and refer to safety advice before travel.
Health Risks
Pre-travel preparation
Before travelling to Iran, Australians are advised to arrange a pre-travel consultation with a travel health doctor, ideally six to eight weeks prior to departure. This allows adequate time to review vaccination history, update routine immunisations, and receive tailored medical advice relevant to the itinerary.
A consultation should consider the full context of travel, including time spent in cities versus rural or remote regions, planned outdoor or desert activities, and any underlying medical conditions. Even when departure is imminent, a consultation remains worthwhile, as essential vaccines can still be administered and key preventive advice provided.
A travel doctor can also prescribe medications where appropriate and provide guidance on managing common travel-related conditions. For those with chronic illnesses, careful planning of medications, documentation, and contingency care is important. Comprehensive travel insurance, including cover for medical evacuation, is strongly recommended.
Insect avoidance
In Iran, the risk of insect-borne disease varies by geography, season, and type of exposure. Mosquito-borne illnesses such as malaria have been largely controlled in recent years, with only limited risk remaining in the far south and southeast of the country, particularly near border regions. Sporadic cases of dengue can still occur, so general mosquito avoidance remains sensible.
Of greater relevance in certain settings is leishmaniasis, a parasitic infection transmitted by sand flies, which is present in parts of Iran. Sand flies are small and often bite at dusk and during the night, making protective clothing and insect repellent important preventive measures.
Ticks also pose a risk in rural and agricultural environments, where Crimean-Congo haemorrhagic fever (CCHF) has been reported. This viral infection is transmitted through tick bites or contact with infected animal blood or tissues, particularly in farming settings. While the risk to typical travellers is low, those visiting farms, handling livestock, or travelling extensively in rural areas should take precautions to avoid tick exposure.
Across all regions, preventive strategies remain consistent. Travellers should wear long, loose-fitting clothing, apply insect repellent containing DEET or picaridin to exposed skin, and ensure accommodation is appropriately screened or air-conditioned. Taking these measures significantly reduces the already low likelihood of insect-borne infection in Iran.
Food and water hygiene
Iranian cuisine is rich and varied, with fragrant rice dishes, grilled meats, herbs, and stews forming the heart of the culinary experience.
Despite generally good food standards in many urban areas, travellers may still develop gastrointestinal illness, particularly when exposed to unfamiliar foods or inconsistent food handling practices. Gastroenteritis is typically acquired through contaminated food or water, with symptoms such as diarrhoea, abdominal cramps, nausea, and occasionally vomiting developing within one to three days.
Preventive strategies include strict hand hygiene before eating, selecting food that is freshly prepared and served hot, and avoiding raw or unwashed produce. Drinking treated or bottled water is recommended, and ice or beverages of uncertain origin should be avoided.
Rabies prevention
In Iran, rabies remains present and is maintained in both domestic and wild animal populations, meaning exposure risk exists even though human cases are relatively uncommon.
Rabies is a viral infection of the central nervous system that causes progressive inflammation of the brain and is almost always fatal once symptoms develop. It is primarily transmitted through bites or scratches from infected animals, most commonly dogs, but also other mammals.
Travellers should avoid contact with stray or unfamiliar animals, even if they appear healthy. The overall risk to most travellers is low, but it increases with activities such as trekking, cycling, or visiting rural and semi-rural areas where animal contact is more likely. A travel doctor can advise whether pre-exposure vaccination is appropriate based on individual travel plans.
Any potential exposure, including bites, scratches, or saliva contact with broken skin, requires urgent medical assessment. Rabies is almost always fatal once symptoms develop, making prompt treatment essential.

Which shots do I need for Iran?
Hepatitis A
+
Hepatitis A is a viral liver infection transmitted through contaminated food and water, and remains a relevant risk for travellers to Iran despite generally improving sanitation standards in urban areas. Infection can range from a mild illness to more prolonged disease with fatigue, nausea, abdominal discomfort, and jaundice.
For Australian travellers, hepatitis A vaccination is commonly recommended if not already completed, particularly for those eating outside major hotels, visiting rural areas, or staying for extended periods. A travel consultation can confirm whether vaccination is indicated based on individual risk and prior immunisation history.
Typhoid
+
Typhoid is a bacterial infection caused by Salmonella Typhi, spread through ingestion of contaminated food or water. It typically presents with sustained fever, fatigue, headache, and gastrointestinal symptoms.
While the overall risk in Iran is lower than in many developing regions, typhoid vaccination may still be considered for travellers who plan to eat in local settings, visit smaller towns, or have prolonged stays. Vaccination provides moderate protection and should be combined with careful food and water precautions.
Measles
+
From a travel health perspective, measles remains an important travel-related infection despite low local transmission. Measles is a highly contagious viral illness spread through airborne droplets, with symptoms including fever, cough, conjunctivitis, and a characteristic rash.
Travellers to Iran should ensure they have received two documented doses of a measles-containing vaccine, such as measles-mumps-rubella (MMR), particularly as exposure risk increases in crowded environments such as airports, public transport, and large gatherings.
Routine vaccinations
+
Australian travellers should ensure that all routine immunisations are up to date prior to travel to Iran. While Australia has high vaccination coverage, some adults may not have received vaccination and some immunity can wane over time.
Vaccines to review include tetanus, diphtheria, pertussis, and measles, with hepatitis B considered depending on individual risk factors. A pre-travel consultation provides an opportunity to assess vaccination history, administer any required boosters, and ensure protection aligns with both Australian guidelines and the specific risks associated with travel to Iran.

Other health risks in Iran
Gastroenteritis
+
Even in a country with relatively good sanitation standards such as Iran, travellers may still develop gastrointestinal illness. Gastroenteritis is most commonly caused by consuming contaminated food or water, particularly in settings where food handling or storage practices are inconsistent. Symptoms typically include diarrhoea, abdominal cramps, nausea, and sometimes vomiting, with onset usually within 24 to 72 hours.
Maintaining hydration is the cornerstone of treatment, ideally with oral rehydration solutions. Most cases are self-limiting, but medical care should be sought if symptoms are severe, persistent, or associated with dehydration or fever. Preventive measures remain essential and include careful hand hygiene, selecting freshly prepared and well-cooked food, and avoiding untreated water or high-risk foods.
Rabies
+
In Iran, rabies remains present and is maintained in both domestic and wild animal populations, meaning exposure risk exists even though human cases are relatively uncommon.
Rabies is a viral infection of the central nervous system that causes progressive inflammation of the brain and is almost always fatal once symptoms develop. It is primarily transmitted through bites or scratches from infected animals, most commonly dogs, but also other mammals.
Travellers should avoid contact with stray or unfamiliar animals, even if they appear healthy. The overall risk to most travellers is low, but it increases with activities such as trekking, cycling, or visiting rural and semi-rural areas where animal contact is more likely. A travel doctor can advise whether pre-exposure vaccination is appropriate based on individual travel plans.
Any potential exposure, including bites, scratches, or saliva contact with broken skin, requires immediate medical assessment. Rabies is almost always fatal once symptoms develop, making prompt treatment essential.
Tuberculosis
+
Tuberculosis (TB) is a bacterial infection caused by Mycobacterium tuberculosis that primarily affects the lungs and is spread through airborne droplets when an infected person coughs, speaks, or sings.
The risk to short-term travellers to Iran is generally low, but increases with prolonged stays, close contact with local populations, or time spent in healthcare or crowded indoor environments. Symptoms of active TB may include a persistent cough, fever, night sweats, and weight loss. Travellers should avoid close contact with individuals who are visibly unwell and seek medical review if symptoms develop during or after travel.
Dengue
+
Dengue is a mosquito-borne viral infection transmitted through the bite of infected Aedes mosquitoes. It can cause fever, headache, muscle and joint pain, and occasionally more severe complications.
In Iran, dengue is not widely established but localised outbreaks have been seen in recent years. Travellers spending time outdoors, particularly in warmer regions or seasons, should take precautions to avoid mosquito bites. Preventive measures such as insect repellent, protective clothing, and screened accommodation are effective in reducing risk.
Middle East Respiratory Syndrome
+
Middle East Respiratory Syndrome (MERS) is a viral respiratory illness caused by a coronavirus, first identified in the Middle East. Transmission is not fully understood but can occur through close contact with infected individuals or exposure to camels, which are considered a reservoir.
Cases have been reported in the region, including Iran, although the overall risk to travellers is low. Symptoms can range from mild respiratory illness to severe pneumonia, with fever, cough, and shortness of breath being common presentations.
Travellers should avoid contact with sick individuals and practice good hand hygiene. Those visiting farms, markets, or areas where camels are present should avoid direct contact with animals and consume only properly cooked food products. Any respiratory illness during or after travel should prompt medical assessment, particularly if there has been relevant exposure.
Non-infectious conditions
Crime and unrest
+
Safety conditions in Iran can change, and travellers should remain aware of local developments. Refer to the Australian Government’s Smartraveller website, for advice on whether to travel, and what degree of caution to take, with higher levels of risk in certain regions due to security concerns and the potential for civil and international unrest.
Petty crime such as theft can occur, and travellers should still take standard precautions, including keeping valuables secure, avoiding isolated areas at night, and remaining alert in crowded public spaces. Demonstrations may occur and can escalate unpredictably, so they should be avoided. It is important to monitor official advice and follow local authorities’ guidance throughout your stay.
Altitude sickness
+
Iran’s varied geography includes high-altitude regions, particularly in the Alborz and Zagros mountain ranges, where elevations often exceed 2,400 metres. Travellers visiting mountainous areas or undertaking trekking may be at risk of altitude sickness if ascending too quickly.
Acute mountain sickness can present with headache, fatigue, dizziness, nausea, and reduced appetite. Symptoms often improve within one to two days if further ascent is paused. In more severe cases, altitude illness can progress to life-threatening complications affecting the brain or lungs, requiring urgent descent and medical care.
Gradual ascent, adequate hydration, and awareness of early symptoms are key preventive strategies. A travel doctor can advise on whether preventive medication is appropriate for higher-risk itineraries.
Deep vein thrombosis
+
Long-haul travel from Australia to Iran, often involving extended periods of immobility, increases the risk of deep vein thrombosis (DVT). DVT occurs when blood clots form in deep veins, usually in the legs, and can lead to serious complications if the clot travels to the lungs.
To reduce risk, travellers should move regularly during flights, perform leg exercises while seated, and maintain adequate hydration. For those with additional risk factors, such as a history of clotting disorders, recent surgery, or prolonged immobility, compression stockings or individualised medical advice may be recommended prior to travel.
