(CNN) The US Centers for Disease Control and Prevention's website has updated, yet again, guidelines for testing people who do not have symptoms of coronavirus. It once again stresses that anyone who has been in contact with an infected person should be tested for coronavirus. "Testing is recommended for all close contacts of persons with SARS-CoV-2 infection. Because of the potential for asymptomatic and pre-symptomatic transmission, it is important that contacts of individuals with SARS-CoV-2 infection be quickly identified and tested," the site now reads. "Viral tests are recommended to diagnose acute infection of both symptomatic and asymptomatic individuals, to guide contact tracing, treatment options, and isolation requirements."
