Low risk of dengue infection predicted for foreign visitors to Rio Olympics, shows study
Three months before the opening of the Rio de Janeiro Summer Olympics, a group of researchers used a mathematical model to calculate the risk of dengue acquisition by the 400,000-odd foreign visitors expected to attend. This model was used with success during the last FIFA World Cup, in 2014. Once again a very low number of dengue cases among foreign visitors to the Olympics is likely, according the study.
