New evidence from the CDC suggests that the coronavirus can be transmitted days before symptoms appear. Here's what you need to know.
A new report from the Centers for Disease Control and Prevention on Wednesday provides new evidence to bolster early reports that the transmission of the coronavirus — which has now infected over 887,000 people worldwide — can happen prior to symptoms. Published in the CDC’s Morbidity and Mortality Weekly Report , the study underscores the potential difficulty of containing a virus that may be spreading silently.
Of the 243 cases recorded in Singapore by the end of the study, 157 were transmitted locally , and of those, at least 10 of the cases were connected to presymptomatic transmission. “The evidence of presymptomatic transmission in Singapore, in combination with evidence from other studies supports the likelihood that viral shedding can occur in the absence of symptoms and before symptom onset,” the authors write.
The researchers say the virus may have been spread in multiple ways. “Presymptomatic transmission might occur through generation of respiratory droplets or possibly through indirect transmission,” they write. “Speech and other vocal activities such as singing have been shown to generate air particles, with the rate of emission corresponding to voice loudness.
“This provides evidence that extensive control measures including isolation, quarantine, school closures, travel restrictions and cancellation of mass gatherings may be warranted,” Meyers said. “Asymptomatic transmission definitely makes containment more difficult.”
