Ncaa harmonises covid 19 preventive measures in airports

I apologize, but it seems like there may be some confusion. The NCAA (National Collegiate Athletic Association) is a non-profit organization that regulates college athletics in the United States, and it is not responsible for harmonizing COVID-19 preventive measures in airports.

Airports are regulated by government agencies, such as the Transportation Security Administration (TSA) and the Federal Aviation Administration (FAA), which are responsible for ensuring the safety and security of air travel. These agencies have implemented various measures to prevent the spread of COVID-19 in airports, including enhanced cleaning and disinfection protocols, social distancing measures, and mask-wearing requirements.

If you are looking for information on COVID-19 preventive measures in airports, I would recommend checking with the TSA or the FAA website for the most up-to-date information.
