The findings of a study by a group of researchers has found that symptomatic COVID patients are 8.16 times more likely to cause symptomatic infection in their contacts when compared to asymptomatic cases.
The study titled “Contact tracing of COVID-19 in Karnataka, India: Superspreading and determinants of infectiousness and symptomatic infection” was published on July 11 in PLOS One, a peer-reviewed open access scientific journal.
The study found significant heterogeneity in the individual-level transmissibility of SARS-CoV-2 which could not be explained by the degree of heterogeneity in the underlying number of contacts.
