Dengue fever, a fast-growing disease

Dengue fever is a global public health concern, and recently an alarming upsurge has been observed in Brazil. In January 2024, over 11,200 cases were reported in Rio de Janeiro, almost half the total for the previous year, highlighting the severity and extent of the epidemic. This situation is exacerbated by climatic factors such as El Niño and climate change, favoring a proliferation of Aedes mosquitoes, vectors of the disease. Before traveling to a high-risk area, whether affected by this infection or not, take out international health insurance!

Do I need health insurance to travel to Brazil in 2024?

For those planning to travel to Brazil or other dengue-affected regions, preparation is essential. The absence of symptoms in three quarters of those infected, and the similarity of symptoms to those of a mild flu in the remainder, make dengue particularly treacherous. Severe forms of the disease, though rare, can lead to severe complications, underlining the importance of proper medical follow-up. In this context, international health insurance becomes an invaluable asset. Not only does it guarantee coverage of medical expenses in case of need, it also offers real peace of mind, knowing that medical assistance is available 24/7. In countries where dengue fever is endemic, and particularly in Brazil with the current situation, being covered is not only recommended, it’s a necessity.

Is dengue fever considered a serious illness?

Dengue fever is indeed considered a serious disease, especially in its severe forms. It is caused by the dengue virus, transmitted to humans by the bites of infected mosquitoes, mainly of the Aedes species. There are four serotypes of the dengue virus, and infection with one of them confers lifelong immunity against that specific serotype, but only partial and temporary immunity against the other serotypes.

The majority of dengue virus infections are asymptomatic, or manifest as mild symptoms that may include:

– Fever,
– headaches,
– Muscle and joint pain,
– fatigue,
– Nausea and vomiting,
– Skin rash.

These symptoms can be similar to those of other diseases, making diagnosis difficult without specific tests. In most cases, there’s nothing to worry about: recovery occurs spontaneously about ten days after the onset of infection.
However, a small proportion of infected people may develop severe forms of the disease, known as severe dengue or dengue hemorrhagic fever. These severe forms can lead to life-threatening complications, such as shock, internal bleeding and vital organs ceasing to function properly. Severe dengue often requires hospitalization and intensive medical care.

How can I prevent and be covered against dengue fever?

According to the World Health Organization, 40% of the world’s population is exposed to dengue fever. Prevention remains the best defense against dengue, mainly through minimizing the risk of mosquito bites, by adopting measures such as :

– Avoid stagnant water to prevent mosquito breeding.
– Apply repellents to skin and clothing.
– Wear covered clothing to protect against bites.
– Be extra vigilant at peak mosquito activity times, such as sunrise and sunset.

However, given the uncertainty and risks inherent in traveling to affected areas, international health insurance provides an extra layer of security. It covers not only medical treatment, but also repatriation and access to medicines that may not be available locally. With the launch of a vaccination campaign in Brazil to control the epidemic, and the announcement of a promising single-dose vaccine for 2025, there is hope for the future. However, until these vaccines become widely available, prevention, combined with comprehensive health insurance, remains the safest strategy for travellers to Brazil.
