It comes after popular holiday spots like Greece have been hit with a wave of new cases of the pest-borne bug this month, two of which resulted in deaths. 2 Mosquitoes that carry deadly West Nile virus are becoming immune to some repellents Credit: Getty 2 The sometimes deadly virus is spread by the Culex mosquito Credit: Getty The virus - which can cause fits and paralysis in severe cases - is spread by the Culex mosquito. After a season of extreme heat and heavy stormy created ideal conditions for the pest to thrive, health officials in the US have now reported that one of the first lines of defence against it no longer seems to be working. Scientists at the Centers for Disease Control and Prevention warned that Culex mozzies NBC news visited have become increasingly resistant to the insecticides that communities use in mass sprays to try to kill the bugs and their eggs. "It's not a good sign," Roxanne Connelly, a medical entomologist with the CDC told NBC news during a visit to a Colorado-based lab that studies the insects. "We're losing some of our tools that we normally rely on to control infected mosquitoes," she went on. Not only are mosquitoes unaffected by a dose insecticide, CDC lab tests showed: those exposed to it are actually living longer. "You want a product that's gonna be able to knock them down, not do this," Dr Connelly told the outlet. However, experiments at the lab have so far not shown that Culex mosquitoes are resistant to mosquito repellent you'd use for outdoor activities and summer evenings. They continue to work well, Dr Connelly said. Brits travelling to Greece this summer were warned to be wary of mozzie bites, after officials at the Greek National Health Care Organisation (EODY) revealed that West Nile virus cases have risen){kind=link}
