I didn’t get that from the website; what I read says:

Las Vegas, Nevada ”¢ Thomas & Mack Center - Las Vegas Events, the Local Organizing Committee for the FEI World Cupâ„¢ Finals, and the Thomas & Mack Center, along with the Las Vegas Convention & Visitors Authority and our resort partners continue to monitor COVID-19 and communicate with our local health officials. To date, there are no travel restrictions imposed on the destination. We remain committed to following the protocols and guidance suggested by the CDC and the Southern Nevada Health District, as the safety and health of our employees and guests remains of utmost priority. In addition, the Thomas & Mack Center will maintain its own safety protocols which will include numerous hand sanitizing locations on site.
All the current CDC guidance is about NOT travelling outside of the US to certain countries, limiting exposure to large groups of people and precautions such as washing your hands.
