Anything to aware of for the Zika virus that is suddenly spread within a day? Does it only apply to pregnant women? Should we be cautious towards LO's nowadays?

While pregnant women are vulnerable, I reckon everyone should be wary and take care in this pandemic. Viruses and diseases in general will afflict anyone who has lower immunity and is in a state of vulnerability (pregnant women, sick people, young children). Follow MOH's recommendations and press releases carefully and take care.

The precautions should be extended to everyone. Pregnant ladies are highlighted because of the potential serious complications if someone pregnant is exposed to the virus.
