The head of the World Health Organization has praised Brazil's response to the Zika virus outbreak, according to AP. Speaking at a news conference in Rio de Janeiro, Dr. Margaret Chan said she was impressed by the government's commitment to tackling the disease. But she also warned the situation could get worse before it gets better. Chan's comments Wednesday evening came at the end of a two-day visit to Brazil during which she met with President Dilma Rousseff and senior Cabinet ministers to discuss the government's strategy for handling the Zika outbreak. Brazilian researchers suspect Zika is linked to an apparent increase in a rare birth defect. Chan also said the government and the International Olympic Committee are working to ensure people's safety at the Olympic Games in Rio in August.
