US Olympic Committee doctor testifies about Zika virus on Capitol Hill


The U.S. Olympic Committee is preparing its athletes and staff ahead of the games in Brazil, a country where Zika virus is spreading rapidly. USOC Doctor Bill Moreau testified about the virus on Capitol Hill Wednesday, saying the committee is considering taking several steps, including pre-treating the clothing of all USOC personnel, and providing bed nets. Health officials now predict they will have a Zika virus vaccine ready for clinical trials by this summer.
