I visited cuba last week of jan 2016 frm canada.was bitten by mosquitoes though no further symptoms. planning pregnancy now. any zika risk/precaution

Probably safe but...: Zika is not yet known to be in Cuba, but no guarantee; the first evidence might not show up for months. Even if you were infected, viremia (virus in blood that can infect a fetus) probably is gone within a couple of weeks. For maximum safety, maybe delay conception another month or so. Excellent info from CDC and WHO: http://www.cdc.gov/zika/index.html/, http://who.int/topics/zika/en/
