NIH official discusses "cluster" of Zika virus cases
Dr. Anthony Fauci, the Director of the National Institute of Allergy and Infectious Diseases, sat down with co-anchor of "CBS This Morning" Charlie Rose to discuss the Zika virus.
The CDC has issued an advisory urging pregnant women to avoid travel to the small area of Miami-Dade County in Florida where the Zika virus is being spread by mosquitoes.
"It is not unexpected you're going to see clusters of cases," Dr. Fauci said.
