Why 72 Hours?

Frequently, there have been questions about the 72 hour quarantine. Here is the latest science on that (06/22/20):

Testing was conducted by applying the virulent SARS-CoV-2 virus (the virus that causes COVID-19) on five materials held at standard room temperature and humidity conditions. The materials tested included typical library items items, i.e. paperback and hardcover books, paper pages inside a closed book, plastic book coverings, and DVD cases, which were provided by Columbus Metropolitan Library. Results show that the SARS-CoV-2 virus was not detectable on the materials after three days of quarantine. The evaluation demonstrates that standard office temperature and relative humidity conditions typically achievable by any air-conditioned office space provide an environment that allows for the natural attenuation of SARS-CoV-2 present on these common materials after 72 hours. https://www.webjunction.org/content/dam/WebJunction/Documents/webJunction/realm/test1-report.pdf
