Brazilian officials vow to step-up "information campaign" to downplay Zika virus fears

Leading American cyclist Tejay van Garderen today withdrew his name from consideration for the Olympics due to concerns he may contract the disease and pass it to his pregnant wife.

Van Garderen, a member of the 2012 Olympic team, who finished fifth at the 2014 Tour de France, was set to form part of the US team for the road race.
