The Winter Olympic Games and the Super Bowl can offer fans not just exciting sports spectacles but also important health insights and information— everything from the risks of viruses and the value of hand washing to the dangers of head blows and why Americans may be slowly changing their minds about how they feel about violent recreations.
Let’s start with what can happen when you put more than 2,000 elite athletes from 92 nations in a village setting in Pyeongchang, South Korea. It’s no surprise that contagious illnesses can break out, and in this case the noxious norovirus. More than 100 cases of the highly infectious viral illness at the Olympic site have been confirmed already, and 1,200 people — many of them security guards for the Games — have been quarantined with disease symptoms. (The South Korean military has sent in forces to assist with security, in place of the quarantined guards).
Norovirus, aka the winter vomiting disease, is a gastrointestinal bug with other symptoms including diarrhea, nausea, and stomach pain, according to the according to the CDC. Its symptoms typically start 12 to 48 hours after patients come in contact with the virus. Symptoms might also include headache and body aches. Fever is uncommon. The sickness is highly contagious, spreading when viral particles get aerosolized over large areas. Hygiene becomes key in outbreaks, as public health experts have emphasized and global cruise lines have discovered.
