Those numbers might seem pretty high, but they are nothing compared to recent reports from Brazil, where the World Health Organization (WHO) recently declared that “it expects Brazil will have more than 2,500 babies born with a severe birth defect known as microcephaly if current trends continue in the Zika virus outbreak.” We’ll talk more about what microcephaly is and the damage it can do, but for now it’s important to understand that with the summer Olympics in Brazil only weeks away, there is a lot of fear in the air around this disease, which could spread rapidly throughout the world and do some serious damage to pregnant women and their babies.

While there is still a lot we don’t know, there are a few things we do know, and if you are pregnant, hoping to become pregnant or of childbearing age you need to listen up and take precaution. Here are some important facts about the Zika virus you need to know to protect yourself, your family and the future of your family.
