Over the years, host countries and cities have had to deal with a variety of concerns, problems, or criticisms, and Rio de Janeiro is no exception. Separately or collectively, a variety of issues might pose risks to the health, safety, and general well-being of athletes and their families, team personnel, and spectators participating in or attending the 2016 Games. Chief among these are the Zika virus, public safety threats, security concerns, and environmental conditions. This book also discusses the possible implications of hosting the Olympics for Brazil and the issue of doping.
