Table 1 Pathogen-specific parameters and estimated impacts of weather-related contact disruption

From: Effects of weather-related social distancing on city-scale transmission of respiratory viruses: a retrospective cohort study

Pathogen Duration of pre-infectious period (days)a Duration of infectious-ness (days)b Number positive samples Median age of infected subjects (years) Percent of infected subjects 18 years or older Estimated basic reproductive number (R0) Estimated reduction in effective contact rate Estimated proportion of infections averted

  1. aDuration of the pre-infectious period (i.e. 1/σ) is the average number of days an individual is in the Exposed (infected but not yet infectious) category in the Susceptible-Exposed-Infectious-Recovered model
  2. bDuration of infectiousness (i.e. 1/γ) is the average number of days an individual is in the Infectious category in the Susceptible-Exposed-Infectious-Recovered model
