World Health agency advises delaying pregnancy over Zika risk

Millions of couples in 46 countries where the Zika virus may pose a risk have been warned to avoid getting pregnant, according to an updated report from the World Health Organization.
The virus is thought to cause birth defects like microcephaly, which prevents the growth of a baby's head and sometimes its brain. Zika has spread throughout Latin American and Caribbean countries, including the U.S. Commonwealth of Puerto Rico and the Virgin Islands.
