Because a baby will rarely be born with a small head is no reason to ignore or dismiss a disease that causes babies to be born with small heads.BTW, you do know that mothers in the US have babies with small heads don't you? Come on now I'm hoping you did some research on the subject if you're going to discuss it.As far as diseases go, Zika is one of the mildests. Most people don't know they have it. Some people get a stuffy nose for a few days. The virus dies in a week. It is only dangerous to the babies of women in the earliest stages of pregnancy.
Zika itself was almost wiped out. Then environmentalists rode to the rescue by banning insecticide and saved this virus from extinction.
