Nicaragua
Travel Destination – Nicaragua
Adventure and culture await in Nicaragua, a country where volcanic highlands rise above tropical rainforests and turquoise Pacific waters lap sandy shores. Colonial architecture, ancient traditions, and dramatic natural scenery combine to create unforgettable experiences, best enjoyed with careful travel health planning before departure.
Health Risks
Pre-travel preparation
A consultation with a travel doctor is strongly recommended prior to visiting Nicaragua. This allows travellers to receive personalised health advice tailored to their medical history and itinerary, whether exploring volcanic craters, kayaking on pristine lakes, or immersing in local culture. Vaccination status can be reviewed, additional immunisations recommended, and prescriptions for necessary medications provided.
Ideally, appointments should be scheduled six to eight weeks before departure, allowing time for multi-dose vaccines. However, even last-minute consultations can be valuable for accelerated vaccination schedules and essential travel health guidance.
Insect avoidance
Mosquitoes and other insects in Nicaragua can spread diseases such as Dengue, Zika, Chikungunya, and Malaria. Transmission particularly occurs in coastal, rural, and low-lying areas. Other insect-borne conditions can include Leishmaniasis, spread by sandflies, New World screwworm myiasis, spread by flies, and Chagas disease, spread by triatomine bugs. Exposure can occur during day or night, depending on the insect and region, making bite prevention an essential component of travel health planning.
Travellers can reduce their risk by staying in air-conditioned accommodation or in rooms fitted with well-maintained window and door screens. When this is not available, sleeping under a bed net provides extra protection. Long-sleeved shirts, long pants, and covered footwear are recommended outdoors, particularly at dawn and dusk when mosquitoes are most active. Insect repellent containing DEET, picaridin, or oil of lemon eucalyptus should be applied to exposed skin, and clothing or gear can be treated with permethrin.
Food and water hygiene
Nicaraguan cuisine is vibrant and varied, featuring fresh seafood, beans, rice, tropical fruits, and traditional street foods. Gastroenteritis is relatively common among travellers and is most often caused by consuming contaminated food or water. Careful attention to hygiene can greatly reduce the risk of travellers’ diarrhoea and other gastrointestinal infections.
Hands should be washed thoroughly with soap and water, or cleaned with an alcohol-based hand sanitiser, before eating. Raw or undercooked foods, particularly meat and seafood, should be avoided, and meals that have been freshly cooked and served hot are safest. Fruit and vegetables are best eaten when they can be peeled, such as bananas, oranges, and mangoes. Drinking water should be bottled, boiled, or properly filtered, and ice should only be consumed if it is known to be made from treated water. Maintaining these precautions is one of the most effective ways to prevent gastrointestinal illness while travelling.
Rabies prevention
Rabies is a virus that can be spread in Nicaragua through bites or scratches from infected animals, particularly dogs and bats. Travellers should avoid contact with animals at all times, including feeding or handling them. Pre-exposure rabies vaccination may be recommended for those planning extended travel, visiting remote areas, or working with animals. Any animal bite or scratch requires immediate medical review. Timely post-exposure treatment is highly effective, as rabies is almost universally fatal once symptoms develop.

Which shots do I need for Nicaragua?
Hepatitis A
+
Hepatitis A is a viral infection that affects the liver and is commonly transmitted through food or water contaminated with the virus. In Nicaragua, the risk of exposure is higher than in Australia, particularly in areas where sanitation and food handling standards may vary. Infection can cause symptoms such as fatigue, nausea, abdominal discomfort, fever, and yellowing of the skin. Whilst Hepatitis A usually causes short term illness, it has potential to lead to prolonged illness, especially in adults. Vaccination is strongly recommended for travellers who have not completed a two-dose course, particularly those travelling outside major cities, staying in homestays, or eating local food frequently.
Typhoid
+
Typhoid a systemic bacterial infection caused by Salmonella Typhi or Paratyphi, and is spread through ingestion of contaminated food or water. Symptoms typically include persistent high fever, headache, weakness, abdominal pain, and gastrointestinal upset, and the illness can be severe without treatment. The risk of typhoid is higher in regions with limited access to clean water and sanitation. A typhoid vaccine, which provides protection for up to three years, may be recommended for travellers staying for extended periods, visiting rural areas, or consuming food outside well-established tourist settings. Maintaining good food and water hygiene remain essential preventative measures.
Hepatitis B
+
The hepatitis B virus infects the liver and is associated with long term complications. Hepatitis B spreads through contact with infected blood or bodily fluids. Transmission can occur through unprotected sexual contact, unsterile medical or dental procedures, tattooing or piercing with unsterile equipment, or sharing personal items such as razors. While many Australians are vaccinated during childhood, not all adults are immune. Hepatitis B vaccination is recommended for travellers to Nicaragua who are planning prolonged stays, may require medical care overseas, or have other specific risk factors. A travel doctor can assess your vaccination history and advise whether immunisation is appropriate.
Yellow fever
+
Proof of yellow fever vaccination may be required for travellers entering Nicaragua from, or transiting through, countries where yellow fever is present. Entry requirements can change, and a travel doctor can provide up-to-date advice on whether vaccination is necessary based on your travel route and itinerary.
Routine vaccinations
+
Routine vaccinations play an important role in protecting travellers from infections that continue to circulate more widely outside Australia. These diseases are less common in Australia due to its strong immunisation program. Diseases such as measles, tetanus, influenza, and COVID-19 may pose a higher risk in Nicaragua due to differing vaccination coverage and exposure settings.
Ensuring that routine immunisations, including measles-mumps-rubella, tetanus, influenza, and COVID-19, are up to date before travel helps reduce the risk of illness. A travel health consultation can identify any gaps in your immunisation history and determine whether booster doses are recommended.

Other health risks in Nicaragua
Malaria
+
Malaria is a serious infectious disease caused by parasites that are transmitted to humans through the bite of infected mosquitoes. In Nicaragua, malaria can be spread in certain lowland and rural regions, particularly along parts of the Caribbean coast. Early symptoms often resemble flu and may include fever, chills, fatigue, headache, and muscle aches. Without prompt diagnosis and treatment, malaria can become severe and potentially life-threatening.
Prevention focuses on avoiding mosquito bites, particularly during evening and nighttime hours. Depending on your itinerary and the regions you plan to visit, your travel doctor may also recommend antimalarial tablets as an additional preventive measure. These medications may be taken before, during, and after travel and can significantly reduce the risk of infection when used correctly.
Dengue
+
Dengue is a viral infection transmitted by mosquitoes that bite during the daytime, particularly in urban and semi-urban environments. It is widespread in Nicaragua and is one of the most common mosquito-borne illnesses affecting travellers. Dengue can cause sudden onset fever, severe headache, pain behind the eyes, muscle and joint aches, and a rash. While many people recover fully within one to two weeks, some infections can lead to more serious complications, especially with repeated exposure.
There is currently no routine dengue vaccine recommended for most travellers, making mosquito bite prevention the primary method of protection. Using effective insect repellent, wearing protective clothing, and reducing exposure to mosquitoes are essential to lowering your risk.
Rabies
+
Rabies is a virus that can be spread in Nicaragua through bites or scratches from infected animals, particularly dogs and bats. Travellers should avoid contact with animals at all times, including feeding or handling them. Pre-exposure rabies vaccination may be recommended for those planning extended travel, visiting remote areas, or working with animals. Any animal bite or scratch requires immediate medical assessment. Timely post-exposure treatment is highly effective, as rabies is almost universally fatal once symptoms develop.
Gastroenteritis
+
Gastroenteritis, often referred to as travellers’ diarrhoea, is commonly caused by food and water contaminated with bacteria. Symptoms usually begin within one to three days and may include diarrhoea, nausea, vomiting, abdominal cramps, and fatigue.
In most cases, gastroenteritis is mild and resolves on its own within a few days. Maintaining hydration is the most important aspect of treatment, and oral rehydration solutions are particularly helpful in replacing lost fluids and salts. Medical attention is recommended if symptoms are severe, prolonged, or atypical. Antibiotics are usually reserved for more severe or persistent infections and for those at risk of complications.
Non-infectious conditions
Crime and unrest
+
Crime rates in Nicaragua vary by region, with petty crime such as theft and pickpocketing more common in urban areas and tourist hotspots. Travellers are advised to remain alert, avoid displaying valuables, and use hotel safes where available. Caution is advised when taking public transport and travelling after dark, particularly in unfamiliar areas.
Travellers should monitor the Australian Government Smartraveller website for advice for Nicaragua before and during travel.
Deep vein thrombosis
+
Deep vein thrombosis (DVT) is a condition in which a blood clot forms in a deep vein, most commonly in the legs. Prolonged periods of immobility, such as during long-haul flights, bus journeys, or road travel, can slow blood flow and increase the risk of clot formation. Symptoms may include leg pain, swelling, warmth, or redness, although some clots cause no symptoms initially.
Travellers can reduce their risk by standing up and moving regularly, performing leg exercises while seated, and staying well hydrated. Those with additional risk factors may benefit from wearing below-knee compression stockings, and should discuss individual prevention strategies with their doctor before travelling.
Safety on the roads and elsewhere
+
From winding coastal highways to rugged jungle tracks, getting around Nicaragua can be part of the adventure, but it also requires careful judgement. Road conditions and driving standards vary significantly, particularly outside major cities. Travellers are advised to use reputable transport providers, wear seatbelts where available, and avoid riding motorcycles unless they are experienced and properly equipped with protective gear.
When hiking or exploring natural areas, suitable footwear, sun protection, and insect repellent are essential, and travellers should remain within their physical limits. Comprehensive travel insurance that covers medical treatment and evacuation is strongly recommended, as access to advanced medical care may be limited in remote areas.
