Zika Virus in Bali: Latest Updates, Risks, and Prevention Tips

If you’ve got a Bali trip coming up, seeing a new Zika warning pop up probably wasn’t something you expected.

The CDC put out a new warning for Bali in August 2026 after people tested positive for Zika after returning home from the island. Since then, there’s been plenty of confusion about how serious it actually is.

Here’s what we know about Zika virus in Bali right now, and what you need to know before your trip.

Is There Zika Virus in Bali?

Yes. Zika virus is a current health risk for travellers to Bali, and in August 2026 the US CDC issued a new Zika Travel Health Notice for Indonesia following cases reported in travellers returning from Bali.

That does not mean there’s a widespread outbreak of Zika Virus in Bali

The important distinction is that Zika infections have been detected in people after travelling to Bali, while Bali’s Provincial Health Office said on 24 August 2026 that its surveillance system had not recorded any confirmed local Zika cases at that time.

So, if you’re travelling to Bali, here’s where things currently stand:

• Zika transmission is considered a risk: Recent infections have been linked to travel in Bali.
• There is a CDC travel notice: Bali is covered by a Level 2 notice, which means travellers should take enhanced precautions.
• There is no confirmed widespread outbreak: Bali health authorities have not announced a Zika outbreak.
• Most travellers can still visit: The CDC is not advising the general public to avoid Bali.
• Pregnancy is different: The CDC currently advises pregnant travellers to avoid travel to Bali because Zika infection during pregnancy can cause serious birth defects.

Zika is mainly transmitted by infected Aedes mosquitoes, the same type of mosquitoes responsible for spreading dengue. This matters in Bali because these mosquitoes are present across the island and are active during the daytime as well as around dawn and dusk.

Current Zika Situation: The CDC currently has a Level 2: Practice Enhanced Precautions Zika notice covering Bali after infections were reported in returning travellers. Bali health authorities say they have not detected confirmed local cases through their surveillance system.

Is There a Zika Travel Warning for Bali?

Yes. The US Centers for Disease Control and Prevention (CDC) currently has a Level 2 Zika Travel Health Notice for Indonesia, with the notice specifically referring to cases reported in travellers returning from Bali.

The notice was issued on 7 August 2026.

A Level 2 notice sounds fairly dramatic, but it does not mean the CDC is telling everyone to cancel their Bali holiday. Level 2 means “Practice Enhanced Precautions.”

For most travellers, that means taking extra care to prevent mosquito bites and following precautions to reduce sexual transmission of Zika during and after your trip.

The advice is more serious if you’re pregnant.

The CDC currently recommends that pregnant travellers avoid travel to Bali because Zika infection during pregnancy can cause serious birth defects. Travellers planning a pregnancy also need to follow specific waiting periods after returning home.

What the CDC Zika Notice Means for Bali Tourists

Traveller	Current Advice
Most tourists	Travel is still possible. Take enhanced precautions against mosquito bites.
Pregnant travellers	CDC recommends avoiding travel to Bali.
Travelling with a pregnant partner	Follow CDC precautions against sexual transmission during and after the trip.
Planning a pregnancy	Check the recommended waiting period before trying to conceive after travelling.
Already booked a Bali holiday	Don’t automatically cancel. Check the advice that applies to your circumstances before travelling.

This is also not the same as a general travel warning for Bali. The notice relates specifically to Zika and the precautions travellers should take.

If you’re pregnant, trying to conceive or travelling with someone who is pregnant, take the warning much more seriously and speak with your doctor or travel health professional before travelling.

Are There Confirmed Cases of Zika Virus in Bali?

This is where the current situation with Zika virus in Bali gets a little confusing.

The CDC says Zika cases have been reported in travellers returning from Bali, which means there is evidence that travellers have contracted the virus after visiting the island.

However, Bali’s own health authorities have not confirmed locally detected Zika cases through their surveillance system.

On 24 August 2026, the Bali Provincial Health Office said that monitoring through health departments, hospitals and healthcare facilities across the island had found no confirmed cases of Zika virus in Bali at that time.

That doesn’t mean the risk can be ignored.

Zika often causes mild symptoms or no symptoms at all, which makes infections difficult to detect through normal healthcare surveillance. Cases diagnosed after travellers return home can therefore provide important evidence of transmission.

There have also been several recent cases associated with travel to Indonesia. UK travel health guidance reports that 11 travel-associated Zika cases were detected in France between July 2025 and March 2026, with most associated with travel to Bali and nearby islands.

So What’s Actually Confirmed About Zika Virus in Bali?

• Zika has been detected: Travellers have tested positive after returning from Bali.
• No locally confirmed cases: Bali health authorities had not detected confirmed cases through their own surveillance as of 24 August 2026.
• No declared outbreak: There has been no official announcement of a widespread Zika outbreak in Bali.
• The CDC considers there to be a risk: The evidence was sufficient for the CDC to issue enhanced travel precautions.

💡 Summary: For tourists, the takeaway is fairly simple: there is currently enough evidence of Zika virus transmission in Bali to take mosquito precautions seriously, even though Bali has not declared a local outbreak.

How Common Is Zika Virus in Bali?

There isn’t currently enough reliable data to put an accurate number on how common Zika virus in Bali actually is.

Unlike dengue, which is regularly diagnosed and reported across Bali, Zika can be much harder to track. Many people infected with Zika develop no symptoms at all, while those who do become sick often experience relatively mild symptoms.

That means infections can easily go undiagnosed.

So far, only a small number of Zika cases have been linked to Bali. The CDC put out its new warning after people tested positive for Zika after coming home from Bali, and a handful of similar cases have also been picked up in Europe.

At the same time, Bali’s Provincial Health Office said in August 2026 that its surveillance system had not detected confirmed local Zika cases.

Zika vs Dengue in Bali

For the average tourist, dengue remains a much more commonly reported mosquito-borne illness in Bali than Zika.

Both viruses can be spread by Aedes mosquitoes, so the practical prevention advice is similar:

• Use mosquito repellent during the day as well as at night.
• Cover exposed skin where practical.
• Use air-conditioned or screened accommodation.
• Don’t assume mosquitoes are only a problem around sunset.
• Take extra precautions if you’re pregnant or planning a pregnancy.

The new warning for Zika virus in Bali doesn’t mean loads of tourists are suddenly catching it in Bali. It just means there have been enough recent cases linked to Bali for health authorities to tell travellers to take a few extra precautions.

Should You Cancel Your Bali Trip Because of Zika?

For most people, no, I wouldn’t be cancelling a Bali holiday over this.

If you’re coming over for a normal holiday, the new Zika warning mostly means being a bit more serious about avoiding mosquito bites. Pack a decent repellent, actually use it, and remember that the mosquitoes that spread Zika bite during the day too.

The situation is different if you’re pregnant or trying for a baby. Zika can cause serious problems during pregnancy, so this isn’t something to brush off with a bit of mosquito spray and hope for the best.

The CDC is currently telling pregnant women not to travel to Bali. If that’s you, speak to your doctor before making any decisions about your trip.

For everyone else, Bali is still very much open for business in 2026. Take the mosquito precautions seriously, but there’s no general advice telling tourists to stay away.

💡 Quick summary: If you’re coming for a normal holiday, there’s no need to cancel your trip because of Zika Virus in Bali. Take mosquito protection seriously and enjoy your holiday. If you’re pregnant or planning a pregnancy, that’s when you need to pay much closer attention to the current advice.

Zika in Bali During Pregnancy

This is the part of the Bali Zika warning you need to take seriously.

If you’re pregnant, the CDC currently recommends avoiding travel to Bali. That’s not because Bali suddenly has a huge Zika outbreak. It’s because catching Zika during pregnancy can pass the virus to your baby and cause serious birth defects.

The difficult part is that you can’t judge the risk by how you feel. Plenty of people who catch Zika never get sick, so having no symptoms doesn’t necessarily mean you haven’t been infected.

If you’re pregnant and already have a Bali trip booked, speak to your doctor or midwife before you travel. Show them the current CDC notice so they’re looking at the same advice you’re seeing online.

If you do decide to travel, mosquito protection needs to be something you stay on top of throughout the trip:

• Use mosquito repellent every day, not just in the evening.
• Reapply it as directed, especially after swimming or sweating.
• Wear longer clothing when it’s practical.
• Keep mosquitoes out of your room and use air conditioning or screens where available.
• Remember that the mosquitoes that spread Zika can bite during the daytime.

💡 Quick summary: If you’re pregnant, this isn’t the section of the warning I’d shrug off. The CDC currently says to avoid travelling to Bali, so speak to your doctor before going ahead with your trip.

How Zika Virus Spreads

Zika is mainly spread through the bite of infected Aedes mosquitoes in Bali, which is the same type of mosquito that spreads dengue.

And annoyingly, they’re not just out looking for you at night. Aedes mosquitoes are active during the day, so putting repellent on before dinner isn’t enough.

• Mosquito bites: The main way Zika spreads, through infected Aedes mosquitoes.
• Sex: Zika can be passed to your partner through sex, including after you’ve left Bali.
• Pregnancy: A pregnant woman can pass Zika to her baby during pregnancy.
• Blood: Zika can also spread through infected blood, although this is much less common.

Zika can also spread through sex. Someone who gets Zika Virus in Bali can pass the virus to their partner after returning home, even if they never felt sick themselves.

You can’t catch Zika from normal everyday contact with someone who has it. Sharing food, sitting next to someone, using the same swimming pool or staying in the same hotel isn’t going to give you Zika.

For tourists in Bali in 2026, mosquito bites are the main thing to worry about, which is why preventing them is such a big part of the current advice.

Symptoms of Zika Virus

Most people who catch Zika Virus won’t actually feel sick. If you do get symptoms, they’re usually fairly mild and can easily be mistaken for another virus.

The symptoms normally start 3 to 14 days after being bitten and can last for several days to a week.

These are the most common symptoms of Zika Virus

• Fever: Usually mild.
• Skin rash: Often one of the more noticeable symptoms.
• Red eyes: Also known as conjunctivitis.
• Joint pain: Often affecting the hands and feet.
• Muscle pain: General aches and soreness.
• Headache: Usually alongside some of the other symptoms above.

👉 Source: You can see the full list of symptoms and official Zika health advice on the CDC website.

The problem in Bali is that Zika and dengue can look pretty similar at first. If you develop a fever, rash or joint pain during your holiday, don’t try to diagnose yourself from Google. Get checked at a clinic or hospital, especially if you’re pregnant.

How to Avoid Zika Mosquito Bites in Bali

You don’t need to spend your Bali trip dressed like you’re heading into the Amazon. A few basic habits will cut down the number of mosquito bites you get.

The main one is repellent. Put it on before heading out in the morning and reapply it according to the instructions on the bottle. The mosquitoes that can spread Zika Virus in Bali are active during the daytime, so don’t wait until sunset.

A few things worth doing in 2026:

• Use proper mosquito repellent: Look for one containing DEET, picaridin or another proven active ingredient.
• Apply it during the day: Zika-carrying Aedes mosquitoes aren’t just an evening problem.
• Reapply when needed: Swimming and sweating can mean you’ll need to put it on again.
• Cover up when practical: Long, loose clothing gives mosquitoes less exposed skin to bite.
• Keep your room closed up: Air conditioning, window screens and closed doors all help keep mosquitoes outside.
• Use the mosquito net if your accommodation provides one: Especially if you’re sleeping somewhere fairly open to the outdoors.
• Don’t rely on mosquito coils alone: They’re handy around a villa or terrace, but they’re not a replacement for repellent.

You won’t avoid every mosquito in Bali. The goal is simply to get bitten as little as possible, and these precautions also help protect you against dengue.

Travel Insurance for Zika Virus in Bali

If you get sick with Zika or another mosquito-borne illness while you’re in Bali, travel insurance can save you from paying the full medical bill yourself.

Depending on your policy, that could include a visit to a doctor, tests, medication or treatment at a private hospital.

If you do need medical care, contact your insurer as soon as you can, especially if you’re being admitted to hospital.

My advice:

• Keep your receipts: You’ll usually need them if you’re claiming back medical expenses.
• Ask for your medical records: Get copies of test results, doctor’s notes and anything else related to your treatment.
• Call your insurer for expensive treatment: They may want to approve treatment or deal directly with the hospital.
• Don’t assume cancellation is covered: A Zika warning doesn’t automatically mean you can cancel your Bali holiday and get your money back.
• Check pregnancy cover carefully: Pregnancy, Zika warnings and deciding not to travel can all be treated differently between policies.
• Read the exclusions: Look specifically for infectious diseases, epidemics, government travel advice and cancellation cover.

If you’re buying insurance after the Zika warning for Bali has already been announced, check the wording carefully. An insurer may treat it as a known event, which can affect what you’re able to claim for later.

If you haven’t sorted your travel insurance yet, you can get a quote from World Nomads before your trip. Their policies are designed for international travellers and can include overseas medical cover, depending on the policy you choose.

If You Think You Have Zika Virus in Bali

If you start feeling sick in Bali and you’ve got symptoms that match Zika, go and get checked at a clinic or hospital. Don’t try to work out whether it’s Zika, dengue or something else from your hotel room.

Tell the doctor you’ve been in Bali and explain when your symptoms started. This is even more important if you’re pregnant, trying for a baby or your partner is pregnant.

While you’re waiting to be checked:

• Drink plenty of fluids: Especially if you’ve got a fever.
• Get some rest: Give yourself a couple of quiet days instead of trying to push through your holiday.
• Keep using mosquito repellent: If you do have Zika, preventing more mosquito bites can help reduce the chance of mosquitoes picking up the virus and passing it on.
• Be careful with painkillers: Don’t take aspirin or other NSAIDs such as ibuprofen until dengue has been ruled out. Dengue can increase the risk of bleeding.
• Tell your doctor if you’re pregnant: Don’t leave this detail until the end of the appointment.

There isn’t a specific medicine that gets rid of Zika. Treatment is generally about rest, fluids and dealing with the symptoms, but getting checked matters because dengue and other illnesses in Bali can initially look quite similar.

Medical Help for Zika in Bali

If you think you might have Zika virus in Bali, you don’t need to find a specialist Zika clinic. Go to a proper hospital or medical clinic and tell them what symptoms you’ve got and when they started.

For mild symptoms, a local clinic is a good place to start. If you’re feeling seriously unwell, pregnant, or your symptoms are getting worse, go straight to a hospital.

Some of the main Bali hospitals tourists use:

• BIMC Hospital Kuta: Handy for Kuta, Legian, Seminyak and the airport.
• BIMC Hospital Nusa Dua: A good option if you’re staying around Nusa Dua or Tanjung Benoa.
• Siloam Hospitals Denpasar: A large private hospital within easy reach of most of South Bali.
• Bali International Hospital: Located in Sanur.
• RSUD Bali Mandara: A government hospital in Sanur.

When you get there, mention that you’re concerned about Zika virus. They may also want to check you for dengue since some of the symptoms can look similar.

If you have travel insurance, contact your insurer as soon as possible if you’re admitted to hospital or need expensive tests or treatment.
