Mosquito invasion: Spain faces rising health threat<\/p>\n
Spain\u2019s sunshine might draw in the tourists, but it\u2019s also rolling out the welcome mat for some of the deadliest mosquitoes on the planet. Experts warn invasive species are spreading fast, and they\u2019re not just bringing itchy bites but the risk of serious foreign diseases like dengue, chikungunya, Zika and West Nile fever.<\/strong><\/p>\n Why mozzies are moving in<\/p>\n Forget long, cold winters. With summers starting earlier, winters turning mild, and just a dash of humidity, Spain is fast becoming mosquito heaven. \u201cIn general, the combination of heat and water is very positive for all mosquitoes,\u201d said entomologist Roger Eritja, of citizen science platform Mosquito Alert<\/a>, as quoted by El Peri\u00f3dico.<\/p>\n They thrive in the tiniest puddles, such as rainwater trapped in plant pots, buckets or even an abandoned bottle cap. Eritja explained: \u201cTheir presence is very related to the water present in small containers in homes.\u201d<\/p>\n Most Read on Euro Weekly News<\/p>\n The deadliest species<\/p>\n Top of the danger list is the tiger mosquito (Aedes albopictus), notorious for spreading nasty tropical viruses. Once a summer nuisance, it is now hanging around longer. \u201cWe can say that, in recent years, there seems to be an extension of its activity period into late autumn and early spring, probably due to mild temperatures,\u201d Eritja warned.<\/p>\n But the tiger is not alone. Spain is now home to three invasive biters. Here\u2019s the danger list: <\/p>\n And it is that last one that gives experts sleepless nights. \u201cFrom a health perspective, the tiger mosquito and especially the yellow fever mosquito are concerning, as they are excellent transmitters of dengue, chikungunya, Zika and other viruses,\u201d Eritja said. The real danger kicks in when someone infected abroad comes home. One bite later, and the virus can spread into the local mosquito population. This can be disastrous. <\/p>\n Climate change: Friend or foe?<\/p>\n Global warming is giving mozzies a major leg-up. Warmer temperatures speed up their life cycle and allow them to thrive in cooler months and higher altitudes. It is what scientists call \u201ctropicalisation,\u201d Spain turning more like the tropics, minus the palm trees.<\/p>\n But before you start picturing a biblical plague, there is a twist. If temperatures soar too high, mosquitoes suffer too. \u201cA strong rise in temperatures harms them as much as humans,\u201d Eritja pointed out. For now, though, the gradual warming trend is working in their favour.<\/p>\n Not all mozzies are equal<\/p>\n Spain actually has more than 60 mosquito species, and most of them don\u2019t tend to bite people. Some prefer wetlands and appear only in spring and autumn, when floods give them breeding grounds. Others, like the tiger and the common house mosquito, are the ones turning your patio into a battlefield.<\/p>\n Tech takes the sting out<\/p>\n The fightback is under way. Spain\u2019s Mosquito Alert project with the Spanish Health Ministry<\/a> has rolled out a new artificial intelligence system called AIMA, which can identify invasive species in less than five minutes from photos snapped by the public. Since 2023, citizen sleuths armed with smartphones have helped confirm the tiger mosquito in 156 municipalities, while the Japanese mosquito has been spotted creeping into parts of Asturias, Cantabria and the Basque Country. With more than 27,000 observations logged in two years, the app has become a vital early-warning tool for health authorities. Every image helps build a live national risk map. When it comes to mozzies, the public really are the eyes on the ground.<\/p>\n The unstoppable march<\/p>\n And the map is filling up fast. First spotted in Spain in 2004, the tiger mosquito has now been confirmed in a jaw-dropping 1,763 municipalities, according to a recent special report by Spanish news outlet Antena 3 Noticias<\/a>. <\/p>\n Once confined to the Mediterranean coast, it has marched north and inland, thriving in areas once thought too cold. From Catalonia to Madrid, Murcia to the Basque Country, and even the Canary Islands where a specimen was recently found in Tenerife, its spread has been practically unstoppable. Experts admit it is an invader that never leaves. \u201cWhere it settles, it establishes itself permanently,\u201d said Eritja, now co-director of the Servei de Control de Mosquits del Baix Llobregat. With 80% of the Mediterranean coast already colonised, health chiefs warn the only option left is to limit numbers, not dream of eradication.<\/p>\n Protect your patch!<\/p>\n Keep an eye on water around the house. That innocent-looking saucer under your flowerpot might be less garden chic and more five-star nursery for killer mozzies.<\/p>\n Don\u2019t give tiger mozzies a home. Empty water from pots, buckets and bottles, and report any sightings on the Mosquito Alert app. Spain\u2019s health depends on all of us keeping these bloodsuckers in check.<\/p>\n\n
