Coronavirus: Studies leave question of ‘airborne’ COVID-19 transmission unanswered

The public should view the new China airborne virus study with caution, because the PCR test cannot distinguish viable virus from genetic fragments that aren’t infectious, said Andrew Noymer, an epidemiologist at the University of California at Irvine. “The test for viable virus is a much-more-painstaking cell culture test, which the present study did not perform,” Noymer said.
