Marcelo Castro On Zika

Brazil's Health Minister Marcelo Castro said on Monday that the Zika epidemic in his country is worse than believed because in 80 per cent of the cases the infected people have no symptoms.

Brazil's health minister says the country is sending some 220,000 troops to battle the mosquito blamed for spreading a virus suspected of causing birth defects - but he also says the war is already being lost.
