After 1 week, this asymptomatic group was reassessed and 10 out of thirteen developed symptoms, resulting in their reclassification as presymptomatic. Likewise in Singapore, 243 cases comprising of seven clusters could be explained by presymptomatic transmission . In 4 of these clusters, the exact date of transmission could possibly be determined to lead to the conclusion that transmission occurred 1-3 days earlier than signs appear within the supply patient. These circumstances show that viral shedding can occur prior to the onset and absence of symptoms, thus complicating the containment of this COVID-19 pandemic.
