Dengue Alert in Italy: Prevention, Symptoms & Treatment Tips 2026

Following a recent confirmed case of dengue in Busto Arsizio, a dengue alert has been triggered across Italy. Below, we analyze the current situation and what the Italian National Institute of Health recommends to combat this infection.

Current Situation in Italy

In 2023, Italy reported 362 confirmed cases of dengue. By March 2024, 48 imported cases had already been recorded. Although Health Minister Orazio Schillaci describes the situation as "not alarming," public concern is rising due to the rapid spread of diseases from other countries and continents. In Brazil, for example, dengue cases have reached approximately 1.3 million, with projections of up to 5 million soon, as there are about 20,000 new infections daily. The Lazio Region, following government directives, is responding with 500 vaccine doses arriving and an additional 2,500 in the coming weeks, available for those traveling to high-risk areas.

General Information About Dengue

The Italian National Institute of Health defines dengue as a viral infection caused by four similar viruses (Den-1, Den-2, Den-3, and Den-4). It is transmitted to humans through the bites of mosquitoes that have previously bitten an infected person. There is no direct human-to-human transmission, although humans are the primary host. The virus circulates in the blood of an infected person for 2–7 days, during which a mosquito can pick it up and transmit it to others. In the Western hemisphere, the primary vector is the Aedes aegypti mosquito, though cases transmitted by Aedes albopictus (the tiger mosquito) have also been recorded.

Symptoms and Diagnosis

Dengue causes fever 5–6 days after a mosquito bite, often with very high temperatures. Additional symptoms include:

• Severe headaches
• Pain behind the eyes
• Intense muscle and joint pain
• Nausea and vomiting
• Skin rashes appearing 3–4 days after fever onset

Typical symptoms are often absent in children, making diagnosis challenging. If you experience these symptoms after traveling to an endemic area, seek medical attention promptly.

Prevention and Treatment

The Italian National Institute of Health states that the most effective preventive measure against dengue is avoiding contact with vector mosquitoes. Key practices include:

• Using insect repellents containing DEET, picaridin, or oil of lemon eucalyptus
• Wearing long-sleeved shirts and long pants
• Using mosquito nets and screens on windows and doors
• Applying repellents during early morning hours when mosquitoes are most active

To reduce the risk of dengue outbreaks, the most effective approach is systematic and continuous mosquito control. This means eliminating all standing water near inhabited areas, such as in flower pots, buckets, gutters, and old tires. For severe infestations, targeted treatments may be necessary. For example, if you are dealing with raccoons that create standing water or attract mosquitoes, you can find effective solutions like the best poison for raccoons to manage these pests.

Treatment

There is no specific antiviral treatment for dengue. Management focuses on supportive care:

• Rest and hydration
• Acetaminophen (paracetamol) for fever and pain (avoid NSAIDs like ibuprofen due to bleeding risk)
• Medical monitoring for severe symptoms

Severe dengue requires hospitalization for intravenous fluids and close observation. Vaccination is available for those traveling to endemic areas, but it is not routinely recommended for the general population in Italy.

FAQ

1. Can dengue be transmitted from person to person?

No, dengue is not directly contagious between humans. It is only transmitted through the bite of an infected mosquito.

2. What should I do if I suspect I have dengue?

Seek medical attention immediately, especially if you have traveled to an endemic area. Early diagnosis and supportive care are crucial.

3. How long does it take to recover from dengue?

Most people recover within 2–7 days, but fatigue may persist for weeks. Severe cases require longer hospitalization.

4. Is there a vaccine for dengue in Italy?

Yes, the vaccine is available for travelers to high-risk areas, but it is not part of the routine immunization schedule for the general population.

5. How can I protect my home from mosquitoes?

Eliminate standing water, use mosquito nets, install screens, and apply repellents. For persistent infestations, consider professional pest control services.
