2015 was a nightmare. We went to Mexico for a holiday and both my husband and myself were bitten to death by mosquitos in the first few days, despite precautions. Upon our return to the UK my husband started displaying symptoms, which gradually got worse over 2 weeks. I am a Ward Manager on an acute stroke unit and thought hubby had had a stroke - tests negative. He continued to deteriorate and was unable to mobilise due to loss of sensation in both legs, which then spread to his hands. His BP, Pulse and Temperature were all deranged and eventually had to be admitted to hospital.
Blood tests were done and my hubby had to be moved to a more acute hospital as neurologically he was deteriorating. Eventually he was diagnosed with Guillain-barre syndrome, which can be fatal as it causes your body to attack itself. His kidney, liver and heart function were all deteriorating. Luckily he was given IV medication to counteract the guillain-barre and after a while he started to get better.
We are now a year further forward and he has made a full recovery, but it could have been so much worse if we hadn't acted promptly.
The blood tests done at the 1st hospital weren't sent across to the 2nd, so they did not know that it showed a positive test for yellow fever. He was not tested specifically for Zika, as there wasn't a test here in the UK at that time. There is no connection between Yellow Fever and Guillain-barre, but there is with Zika. His consultant now believes he was infected with Zika, possibly as well or instead of Yellow Fever.
I did not have any symptoms, but at 45 I'm not planning on extending my family, and you would not necessarily get any symptoms, so I too could have been infected without knowing.
I have to say, we've never been bitten by a mosquito whilst going anywhere in the US, and we've been a fair number of times.
I can fully understand the worry and has completely put us off going anywhere south of the states, especially Mexico! I could now have been sat here a widow, but I'm not and we'd never be put off going to WDW.
