GENEVA (Reuters) - Singapore has handled its Zika outbreak in a textbook fashion so far, while the United States could see the disease spread beyond Florida despite mosquito-control measures, officials at the World Health Organization said on Friday.

Speaking after a meeting of the WHO's emergency committee on Zika, its chairman David Heymann said the disease continued to constitute an international health emergency although the risk to people attending the Paralympics in Rio de Janeiro this month was low.
