Around one million football fans will travel to 12 different cities in Brazil to attend the World Cup due to take place between 12 June and 13 July. The Travel Clinic has issued a warning that they may be facing a risk of Dengue fever.
More cases of this condition have been reported in Brazil compared to the rest of the world between 2000 and 2013. In excess of seven million cases have thus far been reported.
Dengue fever is a viral infection which is transmitted to humans by a specific species of mosquitoes which generally feed during the day.
After the incubation period which could last around three to eight days, the person will experience a headache and fever. A rash will start to develop after three to five days after that, with recurring bouts of fever. The patient may suffer with diarrhoea and vomiting, but this will pass within a few days and there are no serious complications attached to the illness. However, it is possible for it to cause illness that could become life-threatening.
There are no treatments or licensed vaccines available for the illness currently.
Areas, such as Sao Paulo, Porto Alegre, Curitiba, Cuiaba and Brasilia, have a low risk of Dengue fever.
There is a prediction of a chance of the risk exceeding mediocre levels in Manaus, Salvador, Belo Horizonte and Rio de Janeiro.
The cities with the highest risk are Recife, Fortaleza and Natal.
If England reaches the top of their group, they are set to play in Recife on the 29th of June. This places travellers to the game at risk of returning home with Dengue fever.
Travellers who return home and are feeling unwell are advised to seek immediate medical attention.
It is essential for travellers to try and avoid being bitten by these mosquitoes, who are prevalent during the day.
A vaccine is currently being tested, but is not yet available.
The risks can be reduced by air-conditioning, screens, repellents and clothing sprays. Bear in mind to apply your sun cream before you apply the repellents, and re-apply on a regular basis.
