Bulgaria
Travel Destination – Bulgaria
Bulgaria offers a diverse travel experience, from the vibrant capital Sofia to the historic streets of Plovdiv and the beaches along the Black Sea. Travellers can explore monasteries, hike in the Balkan and Rila mountains, or enjoy a mix of European and Ottoman influences in its cuisine and architecture. Healthcare services are generally well developed in major cities, though access may be more limited in rural areas.
For Australian travellers, Bulgaria is considered a low-risk destination for most infectious diseases, but maintaining routine vaccinations, food safety awareness, and general travel precautions remains important.
Health Risks
Pre-travel preparation
Before travelling to Bulgaria, a pre-travel health consultation is recommended ideally six to eight weeks before departure. This allows time to review your vaccination history, assess any underlying health conditions, and ensure routine immunisations are current. Even though Bulgaria has a well-developed healthcare system, travel health preparation remains important because exposure risks can still occur through food, insects, and close contact in crowded environments.
A travel doctor can provide tailored advice based on your itinerary, particularly if you plan to spend time in rural areas, hiking regions such as the Rila or Balkan Mountains, or visiting multiple cities. This is also an opportunity to discuss travel insurance that includes medical care and emergency evacuation, which is important for any international trip.
Food and water hygiene
Bulgarian cuisine includes fresh salads, grilled meats, dairy products, and traditional dishes such as banitsa and shopska salad, which are a highlight of the travel experience. While food safety standards are generally good, travellers can still be exposed to gastrointestinal illness through contaminated food or water, particularly in informal settings or during high tourist season.
Preventative measures include washing hands thoroughly with soap and water before eating, or using alcohol-based hand sanitiser when washing facilities are unavailable. Choosing food that is freshly prepared and served hot reduces risk, as does avoiding foods that have been sitting uncovered or at room temperature for long periods. Raw or undercooked meat, unpasteurised dairy products, and unwashed fruits or vegetables should be avoided or carefully prepared. Bottled water is a common choice for travellers, particularly in rural areas or when water quality is uncertain.
Insect avoidance
In Bulgaria, mosquito and tick exposure is generally seasonal and more common in warmer months, particularly in rural, forested, and grassy areas. The CDC highlights that ticks in parts of Europe can transmit infections such as Lyme disease and tick-borne encephalitis virus, while mosquitoes may contribute to sporadic viral infections in some regions.
To reduce risk, travellers should use an insect repellent containing DEET, picaridin, or oil of lemon eucalyptus on exposed skin, especially when outdoors. Wearing long sleeves, long trousers, and closed footwear is recommended when walking in grassy or wooded areas. Checking the body for ticks after outdoor activities is an important preventative step, particularly around the scalp, behind the ears, and behind the knees. Sleeping in screened or air-conditioned accommodation can also help reduce exposure.

Which shots do I need for Bulgaria?
Hepatitis A
+
Hepatitis A is a viral infection of the liver caused by ingestion of contaminated food or water. It can spread easily in environments where hygiene is compromised and may cause symptoms such as fever, nausea, abdominal pain, fatigue, and jaundice which refers to yellowing of the skin and eyes. Illness can last weeks and, although rarely fatal, may significantly disrupt travel.
Vaccination is strongly recommended for most travellers to Bulgaria who are not already immune. The vaccine is given as a two-dose course and provides long-term protection. Even with vaccination, maintaining good food and water hygiene remains important as an additional layer of protection.
Measles
+
Measles is a highly contagious viral respiratory infection spread through airborne droplets when an infected person coughs or sneezes. It typically causes fever, cough, runny nose, red eyes, and a characteristic widespread rash. In some cases, it can lead to serious complications such as pneumonia or brain inflammation.
Outbreaks continue to occur in parts of Europe, including destinations frequented by international travellers. Because measles spreads easily in crowded environments such as airports, public transport, and tourist sites, ensuring immunity is essential. Travellers born during or since 1966 need to know that they have received two documented doses of a measles-containing vaccine.
Influenza
+
Influenza is a viral respiratory illness spread through droplets and close contact, causing fever, cough, sore throat, muscle aches, and fatigue. It circulates seasonally in Europe, including Bulgaria, with peak transmission typically occurring during the colder months. However, with international travel and a wide range of exposures, transmission can occur year-round.
Annual influenza vaccination is recommended for all travellers, particularly those at higher risk of complications such as older adults, pregnant women, and people with chronic medical conditions. Vaccination reduces the risk of infection and can also lessen the severity of illness if infection occurs during travel.
COVID-19
+
COVID-19 is a respiratory infection caused by the SARS-CoV-2 virus and spreads primarily through close contact and airborne droplets. Symptoms can range from mild respiratory illness to more severe disease involving pneumonia and breathing difficulties.
Travel increases exposure risk due to time spent in airports, aircraft, and crowded indoor settings. Travellers are advised to remain up to date with COVID-19 vaccination in line with Australian recommendations, including booster doses for older adults and those with underlying health conditions. Vaccination helps reduce the risk of severe illness, hospitalisation, and disruption to travel plans.
Routine vaccinations
+
Routine vaccinations protect against a range of preventable infectious diseases that can still circulate internationally, even in destinations with advanced healthcare systems like Bulgaria. These include tetanus, diphtheria, pertussis, polio, and measles. While these conditions are uncommon in Australia due to strong immunisation programs, exposure risks can be higher overseas.
A travel health review can ensure all routine vaccinations are up to date and identifies whether booster doses are required based on age, medical history, and previous immunisation records. Additional vaccines such as hepatitis B may be advised depending on risk factors and itinerary plans. Staying current with routine vaccines is one of the most effective ways to reduce preventable illness during international travel.

Other health risks in Bulgaria
Gastroenteritis
+
Gastroenteritis, often called traveller's diarrhoea, can occur even in countries like Bulgaria where food standards are generally good. It is usually caused by infection from bacteria or viruses that are spread through contaminated food, water, or poor hand hygiene.
Symptoms typically begin within a few days of exposure and may include diarrhoea, stomach cramps, nausea, vomiting, and sometimes fever. Most people's experiences of gastroenteritis are mild, and often resolve within a few days. The main risk during travel is dehydration, particularly in hot weather or when symptoms are frequent. Maintaining fluid intake is essential, and oral rehydration solutions can help replace lost salts and fluids more effectively than water alone.
Prevention focuses on practical hygiene habits such as washing hands before meals, choosing freshly prepared and thoroughly cooked food, and avoiding items that have been left uncovered or stored unrefrigerated for long periods. Bottled water is preferred where water quality is uncertain, particularly in rural locations.
Tuberculosis
+
Tuberculosis (TB) is a bacterial infection that usually affects the lungs and spreads through prolonged close contact with an infected person via airborne droplets. It is not a common risk for short-term travellers to Bulgaria.
The disease develops slowly, and symptoms can include a persistent cough, fever, night sweats, and weight loss. Transmission typically requires extended exposure in enclosed indoor environments, so casual contact or brief travel exposure carries very low risk. Routine precautions such as good ventilation and general health awareness are sufficient for most travellers.
Non-infectious conditions
Crime and unrest
+
As with most international travel destinations, travellers should remain aware of their surroundings in Bulgaria, particularly in larger cities such as Sofia and in busy tourist areas. Petty crime, including pickpocketing, bag snatching, and theft, can occur in crowded places such as public transport hubs, markets, and popular attractions.
Occasional large gatherings, protests or political demonstrations may take place and can become unpredictable. These should be avoided as a precaution, even if they appear peaceful. Travellers are advised to keep valuables secure, avoid displaying expensive items, and use reputable transport services where possible.
Staying informed through official travel advisories before and during the trip is recommended, particularly in the event of local disruptions or public events that may affect transport or access to services. Refer to the Australian Government's Smartraveller website for up to date safety advice and information.
Deep vein thrombosis
+
Deep vein thrombosis (DVT) is a condition where a blood clot forms in a deep vein, most commonly in the legs, during periods of prolonged immobility such as long-haul flights from Australia to Bulgaria. When blood flow slows down due to sitting for extended periods, clotting can occur, particularly in susceptible individuals.
Symptoms of a DVT may include swelling, pain, tenderness, or warmth in one leg, although it can also occur without obvious symptoms. In rare cases, a clot can travel to the lungs, causing a pulmonary embolism, which is a medical emergency.
Reducing risk involves keeping blood circulation active during travel. This includes standing and walking when safe, performing regular leg and ankle movements while seated, and avoiding crossing legs for long periods. Staying well hydrated and limiting alcohol intake can also help. Travellers with additional risk factors such as recent surgery, pregnancy, clotting disorders, or previous DVT may require medical advice before travel and, in some cases, compression stockings.
