Zika Question

Hey ladies! My husband is going to Ecuador in March on a mission trip. I was supposed to go but we decided it would be best for me to stay home after we found out I was pregnant. This was before we even heard about the Zika virus. The CDC released a statement recently that basically says if a man travels to a Zika-affected area and has a pregnant partner he should abstain from sex or use a condom until the baby is born. This is scary to me. We need advice... Should he go or should he not? Thanks!
