Besides, the patient should drink a lot of water every day, eat a light diet, should not eat fatty foods. To prevent allergies, patients should limit foods that cause severe allergies, such as seafood, beef, bush meat or foods to which the patient’s body is already allergic.

Accordingly, the physician may consider giving the patient an antihistamine to help relieve itching, or an anti-allergy medication (eg, Loratadine).

Ibizan health officials have urged tourists to beware of dengue fever.

From May to November last year, there were several outbreaks of dengue on the island. The virus is carried by mosquitoes.

There is still a “moderate” risk that tourists could be infected with the virus this summer, health authorities warn.

What are the symptoms to watch out for and how can you protect yourself?

How many tourists got dengue in Ibiza last year?

Dengue fever is spread by mosquitoes that carry the virus. This disease is common in areas with hot and humid climates. It is not contagious and is not transmitted from person to person.

Six German tourists contracted dengue in Ibiza between May and November last year. A 27-year-old woman, her partner and their 13-month-old daughter were infected in August 2022. Another family – a 37-year-old woman, her partner and their nine-year-old son – allegedly contracted the virus in the same city in October 2022.

The risk of contracting the virus is currently low, but will increase to moderate in summer.

“One of the potential vectors of dengue is the Aedes albopictus mosquito, which is distributed throughout the Spanish Mediterranean and the Balearic Islands, as well as in some inland and northern regions of the country” , a spokesman for the Spanish Ministry of Health said.

“After learning about these cases, the authorities of the Balearic Islands took action: surveillance and control of vectors are carried out, public information is being carried out” , – said the representative of the department.

Symptoms appear between four and ten days after the mosquito bite. If you suspect you have a virus, see your doctor as soon as possible.

Although most people recover without treatment in about a week, about one in 20 people may develop severe symptoms. In this case, you should immediately go to the emergency room. The risk is increased for those who have previously been infected with the virus.

Abdominal pain, vomiting of blood, bleeding from the nose or gums are symptoms of severe dengue.

How can you protect yourself from dengue?

There is a dengue vaccine approved for use in the European Union, but it is only recommended for people who have had dengue once.

The best way to prevent infection is to avoid mosquito bites. Wear long sleeves, use repellent, and sleep under a mosquito net.
