00:00A deadly threat may be creeping into the UK, and it's no bigger than your fingertip.
00:04For the first time ever, scientists have found mosquitoes in Britain that can spread deadly
00:08tropical diseases.
00:10The Egyptian and tiger mosquitoes, known carriers of Zika, Dengue fever, and chikungunya, were
00:16discovered in Kent and near Heathrow Airport.
00:19But don't panic just yet.
00:20Experts say these were isolated cases, likely arriving via cars or cargo from Europe.
00:26So far, there's no proof they've established themselves in the UK.
00:29But here's the real concern.
00:31As climate change warms the country, and winters get milder, the UK could soon become a perfect
00:36breeding ground.
00:38Tiger mosquitoes already thrive in parts of Europe, and they may be active in southern
00:42England within 50 years.
00:44If these bugs settle in and the temperatures rise just enough, deadly viruses could begin
00:48to spread, right here at home.
00:51It's not a crisis yet, but it's a wake-up call, because when it comes to climate and disease,
00:56the world is more connected than we think.
