Spain holiday warning: Costa del Sol faces deadly mosquito alert – affected areas

Last year, 87 people were affected by the virus in Andalusia, the region where Costa del Sol is located in the south of Spain, and eight were killed. The Andalusian Government has decided to act now as some regions are currently at high risk.

According to health officials, the highest level is recorded in Benahavís, in Malaga. The authorities are implementing prevention plans as well as surveillance and control measures in these regions.

The Nile virus is generally transmitted by mosquitos that bite birds, which carry the virus and deposit it in both humans and horses.

The Centers for Disease Control and Prevention said the “West Nile virus (WNV) is the leading cause of mosquito-borne disease in the continental United States. It is most commonly spread to people by the bite of an infected mosquito. Cases of WNV occur during mosquito season, which starts in the summer and continues through fall,” it stated.

The NHS explained: “Some people develop mild flu-like symptoms, a skin rash and may feel sick. The infection usually goes away on its own without treatment. The virus is not contagious. You only get it from being bitten by an infected mosquito.”

In some cases, the virus can cause a neuroinvasive disease such as encephalitis, meninigitis or poliomyelitis.

Last year’s outbreak, which was the worst Nile virus ever registered in Spain, started in the riverside towns of Coria del Río and La Puebla del Río and then spread to parts of Seville.

It quickly arrived at the coastal resort of Cadiz in August.

Drones were used to spray the areas where the mosquitos had been detected and to kill their eggs.
