NEW YORK (AP) — The Rio Olympics are not likely to have a major impact on the spread of Zika virus, although four developing countries could face a substantially higher risk, according to a new government estimate.
U.S. researchers tried to calculate whether the Olympics in Rio de Janeiro, which is in the midst of a Zika epidemic, will lead to outbreaks that wouldn’t have happened otherwise. The danger is that infected travelers might be bitten by mosquitoes after return to their home nations, which would potentially spread Zika to other people and spark an outbreak.
