UK tourists in Canary Islands warned to 'avoid water and trees'

UK tourists in Spain have been warned over deadly disease-carrying mosquitos invading popular islands. Aedes tiger mosquitos were found in containers arriving from Castellón in mainland Spain to parts of the Canary Islands.

Larvae and pupae were also found in olive trees transported to Tenerife. Aedes mosquitos can transmit diseases such as dengue virus, yellow fever virus and Zika virus. Travel Health Pro said: "The risk of insect bites, and possible vector-borne disease, to the traveller will depend on exposure to insects.

"This will be determined by destination, season and rainfall patterns, as well as activities undertaken, length of stay and measures taken to avoid insect bites. Vaccines and tablets are available to help protect against some of the diseases, but may not be suitable for all travellers, placing them at higher risk of disease.

"Avoiding bites from insects and ticks may be the only way to reduce the risk of disease. As dengue is spread by day-biting mosquitoes, particular care with bite avoidance is advised during the day, especially around dawn and dusk."

It added a good way to reduce your risk of a mosquito bite is to "avoid areas of stagnant or standing water, where mosquitoes are likely to breed". The warm and humid climate of the Canary Islands creates an ideal breeding ground for mosquitoes.

With temperatures that remain consistently mild throughout the year, these insects thrive, increasing the risk of disease transmission. Many people infected with Zika virus will not have symptoms or will only have mild symptoms, the CDC in the United States has warned previously.

Symptoms usually last for several days to a week. Zika infection during pregnancy can cause serious birth defects and is associated with other pregnancy problems. Rarely, Zika infection can cause Guillain-Barré syndrome (GBS) or severe disease affecting the brain.
