Argentina Reports Zika Virus Cases in 2025: What Tourists Need To Know And How To Remain Alert!

Published on September 3, 2025

In 2025, Argentina is seeing a sharp rise in Zika virus cases. By second September, the Pan American Health Organization (PAHO) confirmed more than seven hundred infections. That’s a big jump from the five-hundred and sixty-four cases reported for all of 2024. With the outbreak spreading, travelers thinking about a trip to Argentina need to be careful and therefore, checked. Right now, there’s no vaccine or specific medicine to stop the virus, so protecting yourself is more important than ever.

Zika Virus in Argentina: A Growing Concern for Tourists

Zika virus, which is primarily transmitted through the bite of infected Aedes mosquitoes, has raised alarms in Argentina, especially in tourist hotspots. While the United States Centers for Disease Control and Prevention (CDC) has not issued a travel advisory for Argentina, the United Kingdom’s Travel Health Advisory warns of the presence of the virus within the country. Tourists, particularly those expecting to travel in areas where mosquitoes thrive, should remain cautious.

Zika is particularly dangerous for pregnant women, as it can cause serious birth defects in babies born to mothers who have been infected with the virus. The CDC and UK Travel Health Advisory both recommend that pregnant women consult healthcare providers before traveling to affected regions. In addition to this, general health precautions should be observed, such as using mosquito repellent and wearing long-sleeved clothing.

Tourist Destinations Affected by the Zika Outbreak

Though exact locations affected by the Zika virus are not always specified, the regions with higher mosquito populations, particularly those with tropical or subtropical climates, are the areas at greatest risk. This includes key tourist destinations in Argentina where tourists are most likely to encounter mosquitoes, including:

• Buenos Aires: Argentina’s bustling capital city, known for its vibrant culture and historic landmarks, has seen several reports of Zika cases.
• Iguazu Falls: A popular natural wonder located near the border with Brazil, Iguazu Falls attracts thousands of visitors every year, though it is an area where mosquito activity is high.
• Bariloche: Located in the Argentine Patagonia region, Bariloche offers scenic lakes and snowy mountains, but is also a region prone to Zika virus transmission.
• Mendoza: Known for its vineyards, Mendoza also lies in an area where mosquitoes can spread the virus.
• Cordoba: The city of Cordoba and its surrounding areas are important tourist destinations with a large number of visitors each year.

While the virus can spread throughout Argentina, these areas are particularly relevant to tourists. Visiting these sites may pose an elevated risk of mosquito bites, particularly during the warmer months, when mosquito activity peaks.

How to Protect Yourself from Zika Virus While Travelling in Argentina

Given the risk posed by the Zika virus, it is essential for all tourists heading to Argentina to follow proper safety protocols to reduce exposure to the virus. Below are some recommended measures to stay safe:

1. Use Mosquito Repellent

Mosquito repellent containing DEET, picaridin, or oil of lemon eucalyptus is a must. Apply it frequently, especially if spending time outdoors during the day and night when mosquitoes are most active.

2. Wear Protective Clothing

To minimise exposure to mosquitoes, it is advisable to wear long-sleeved shirts, long pants, and socks. Light-coloured clothing is better as it can make it easier to spot mosquitoes.

3. Stay in Air-Conditioned or Well-Screened Accommodations

Ensure that your accommodation has proper mosquito screens or air conditioning to keep mosquitoes out. Avoid staying in open, non-air-conditioned areas, especially in rural or jungle settings.

4. Avoid Peak Mosquito Hours

The mosquitoes responsible for transmitting Zika are most active at dawn and dusk. Try to limit your outdoor activities during these times and stay indoors as much as possible.

5. Keep Mosquito Nets Handy

If you plan to stay in areas where mosquitoes are abundant, consider sleeping under a mosquito net to protect yourself during the night.

Symptoms of Zika Virus and When to Seek Medical Attention

It is important for travellers to be aware of the symptoms of the Zika virus, as early detection can lead to better management of the condition. The most common symptoms of Zika virus infection include:

• Fever
• Rash
• Joint pain
• Conjunctivitis (red eyes)

These symptoms usually appear 2-7 days after being bitten by an infected mosquito. Most cases are mild, and individuals recover without the need for special treatment. However, pregnant women and those who develop severe symptoms should seek medical advice immediately.

Travel Advisory and Government Recommendations

As of now, the Argentine government has not issued a formal travel advisory regarding the Zika virus outbreak, but the PAHO’s warning highlights the ongoing risk. The Argentine Ministry of Health has reiterated that tourists should follow recommended preventive measures to avoid contracting the virus.

The National Institutes of Health (NIH) advises pregnant women to reconsider travel to areas with a risk of Zika virus transmission. Both the CDC and PAHO also recommend that travelers take necessary precautions to avoid mosquito bites, as there is no vaccine or specific treatment available for the virus at this time.

The Impact on Tourism and Health Concerns

The rise in Zika virus cases has raised concerns about its impact on Argentina’s tourism industry. While the government continues to monitor the situation, tourism officials urge visitors to take personal responsibility for their health. Public health campaigns are being launched to educate both locals and tourists on the dangers of Zika and the importance of prevention measures.

While Zika may be a concern for some travellers, it is important to note that millions continue to visit Argentina every year without incident. By following the necessary precautions, tourists can continue to enjoy Argentina’s diverse attractions while staying safe.

Stay Healthy While Discovering Argentina

Argentina is working hard to manage its Zika virus outbreak in 2025, and you can still safely visit. Stay ahead of the virus by using mosquito repellent, dressing in long sleeves and pants, and picking hotels that have good screening on windows and doors. These simple habits let you roam the glowing mountains and street fairs of Buenos Aires worry-free. If pregnancy is part of your travel plan, though, talk to your doctor before you book anything; Zika can have serious effects during pregnancy.

Checking in regularly with trusted health sources, like the CDC, the UK Travel Health, and Argentina’s own Ministry of Health will keep you in the loop. When health websites update, adjust your travel habits. This way you can experience Argentina’s diverse culture and breathtaking scenery, all while looking after your health. Safe travels!
