Bali is a top travel destination known for its stunning beaches, vibrant culture, and exciting nightlife. However, travelers should also be aware of potential health risks and diseases that may be present on the island. Taking precautions and staying informed can help ensure a safe and enjoyable trip. Below are some common health risks in Bali.
1. Food poisoning otherwise known as "Bali belly"
Bali Belly is a common issue among travellers caused by consuming unsanitary food or water. Symptoms typically include stomach cramps, nausea, vomiting, and diarrhoea.
Prevention Tips:
- Drink only bottled or filtered water.
- Avoid ice cubes unless you're sure they're made from purified water.
- Eat at reputable restaurants and avoid street food if unsure of hygiene standards.
- Wash hands frequently and use hand sanitizer.

2. Dengue Fever
Dengue fever is a mosquito-borne disease that can cause high fever, severe headaches, joint pain, and rashes. It is prevalent in tropical regions, including Bali. While there is a vaccine available for the dengue virus, its efficiency rate is not as high as one might want, therefore its availability remains limited to high risk area - this means you most likely will not be able to find at home before your trip to Bali.
If you suspect you are infected with dengue, visit a doctor as soon as possible - most patient end up hospitalised for a few days in order to recover properly.
Prevention Tips:
- Use insect repellent with DEET.
- Wear long sleeves and pants, especially during dawn and dusk.
- Stay in accommodations with mosquito screens or air conditioning.
- Remove standing water to prevent mosquito breeding.

3. Rabies
Rabies is a serious viral disease that can be transmitted through bites or scratches from infected animals, particularly stray dogs and monkeys. While the the disease has been mostly eradicated in large parts of the world, it is unfortunately still present in Bali. It usually spreads in more remote areas where animals are not always cared for. But it can, at times, make its way to the more affluent parts of the island.
If you get bitten by an animal in Bali - go visit a hospital right away where they will most probably advise you to get a rabies shot. At no cost wait to visit a medical establishment as, if not treated right away, rabies has a high rate of fatality.
Prevention Tips:
- Avoid contact with stray animals.
- Do not feed monkeys at tourist sites.
- If bitten or scratched, wash the wound with soap and water immediately and seek medical attention.

4. Alcohol and Methanol Poisoning
Consuming alcohol in Bali comes with risks, particularly due to cases of methanol poisoning in counterfeit or locally made spirits. Symptoms include dizziness, nausea, confusion, vision problems, and, in severe cases, coma or death.
In order to save costs, unscrupulous bars or suppliers might "bootleg" their alcohol without proper knowledge if distillation - resulting in concocting a deadly beverage.
Prevention Tips:
- Avoid cheap, unbranded alcohol, especially local arak.
- Purchase alcohol from reputable bars, restaurants, or duty-free shops.
- Be cautious with cocktails and mixed drinks in lesser-known establishments.
- If you suspect methanol poisoning, seek immediate medical attention.

Staying Safe in Bali
While these health risks exist, they can be managed with the right precautions. Ensure you have travel insurance that covers medical emergencies and seek medical attention if you experience any concerning symptoms. By staying informed and prepared, you can fully enjoy everything Bali has to offer without unnecessary health concerns.
