On the surface, this seems obvious. No need to get graphic here. However, as I thought about this, I wonder if STDs - as they now say Zika is - are really spread by “sucking face” more than anything else. How do they know? And, if my suspicion is correct…is kissing quietly included in the definition as sexual? Maybe someone in the health care profession can enlighten us on how they (CDC or WHO) know what they really know. Or, is some of their base knowledge actually speculative?
What’s the SD? …not STD!
