Zika Spurs Golfer Rory McIlroy to Pull Out of Rio Olympics
Irish golfer Rory McIlroy says he won't go to the Olympic Games in Rio de Janeiro, Brazil because he is concerned about the Zika virus.
He is the highest-profile athlete yet to withdraw from Rio over severe birth defects and other health concerns linked with the mosquito-borne virus, and his announcement Wednesday is expected to increase debate about holding the games during a public health emergency, The New York Times reported.
Other athletes who have pulled out of the games scheduled to begin in six weeks include American cyclist Tejay Van Garderen and golfers Marc Leishman of Australia and Vijay Singh of Fiji.
U.S. men's volleyball coach John Speraw said he plans to preserve sperm for a possible future pregnancy before traveling to Rio, and Spanish basketball star Pau Gasol said he was considering the same thing, The Times reported.
Olympic officials say the athletes' risk from Zika is minimal.

Harmful Algal Bloom Reporting System Launched by CDC
A new national reporting system for harmful algal blooms has been launched by the U.S. Centers for Disease Control and Prevention.
The system will collect data from public health agencies on harmful algal blooms and human and animal illnesses they cause.
Harmful algal blooms are becoming more common and severe due to climate change, farming practices, storm and wastewater runoff, and other environmental causes, the CDC said.
Algal blooms can produce toxins that get into water, air and food, and severely deplete oxygen in bodies of water. Along with posing a threat to the local enviornment, these toxins can cause a number of health problems in people and animals.
"Breathing in these toxins can cause coughing or respiratory problems, and swimming in water with a harmful algal bloom can cause skin rashes or other symptoms. People also can get sick from eating fish or shellfish or drinking tap water contaminated with the toxins," according to a CDC news release.
