There is a blood test he can get done which will show if he was infected, but the advice is to leave 6 months between potential exposure and conception, and you left 5 months, so I wouldn't worry too much
The test is about £150 if you want to set your mind at rest
I actually spoke to my GP about being tested and she said at this stage results could show a false negative or positive, so would be inconclusive either way. I'm booked in for an additional scan at 30 weeks to check measurements. I hate this worry!
The 6 month rule doesn't apply in all countries. In Australia for example the advice is to wait 8 weeks before ttc after being to a Zika infected country (a lot of Aussies travel to neighbouring countries in SE Asia where Zika is a significant risk).
We went to Thailand 3 months before conceiving and DH had also been in Singapore. The doctor said test can't detect Zika more than 6 weeks after suspected infection. But even though it's scary the risk is very very small. Brazil has 200 million people and 200,000 Zika cases (total not only pregnant women). That's 0.1%.
Please don't ruin your pregnancy by worrying about this. I know many pregnant people in a country where there are many more cases than Mexico, and no one is even remotely worried about it.
I travelled to said country before getting pregnant 5 months later, and spent my pregnancy worried about it. I am now holding my baby (91st centile head circumference- ouch!) and really wish I hadn't worried.
Think of it this way - if your baby were to have a problem due to zika, it would be the first recorded case in the whole world of transmission after 5 months!!!! How unlikely is that??
Yes. We had this worry. We went to Cuba last June and got pregnant pretty much straight after we got back. I spent a lot of my time pregnant worrying about zika, however he twenty week scan showed normal head measurements and we now have a perfect 17 week old dd. Please try not to worry as you (unlike me ) left it almost 6 months before you got pregnant.
