Another member suggested I post this here as well as travel hope it helps people to stay safe.
Thomson Holidays and First Choice Holidays do not recognise Cape Verde as having Zika Virus (despite 4000+ cases) so you may find you have trouble getting refunds/ changing your holiday - I'm currently in this situation would have no problem going if I wasn't 25 weeks pregnant.
They won't change my flights until the FCO put out a specific warning for Cape Verde. Staff in shops also giving out its "safe as far as they are concerned" advice.
So please be wary if pregnant and check all advice before traveling or booking. Trying to get their attention via twitter but seems to be falling on deaf ears any retweets greatly appreciated twitter.com/HareDawn/status/691344415592468485
I've already decided I'll not go whatever happens but want to help awareness for all pregnant women
