In this study of 45 patients with COVID-19 undergoing tracheostomy, nasopharyngeal and tracheal cycle threshold (Ct) values were analyzed. Ct values rose to 37.9 by the time of tracheostomy and remained >35 postoperatively, demonstrating that persistent test positivity may not be associated with persistent transmissible virus in this population.
