Here's Brazil's Plan for a Zika-Free Olympics

From polluted waterways to terrible planning, organizers of the 2016 Summer Olympics set to take place in Rio de Janeiro have faced plenty of challenges. The latest: the mosquito-borne Zika virus that has been linked to serious birth defects in newborn babies. Authorities in Brazil—home of the largest-known outbreak of the virus, which has spread through Latin America and the Caribbean—have announced plans to prevent Zika's spread during the games, the BBC reports. Measures include:

• Inspections starting four months before the games to wipe out breeding grounds.
• Daily mosquito sweeps during the games.
• Fumigation on a case-by-case basis.

Also, officials say, August is a cooler, drier month, when mosquitoes are less common.
