COVID-19 pandemic: Impact of lockdown, contact and non-contact transmissions on infection dynamics.
Category: Article Summary
Topic: Modeling and Prediction
- Roy adapted the classical epidemic modelling framework and incorporated a direct person-to-person contact and indirect airborne and fomites-driven transmission parameters to assess the effectiveness of lockdown. To be effective, the models suggest that considerable reduction in both contact and non-contact transmission rates over a long period is required. The author concludes that any premature withdrawal of lockdown can lead to a quicker, sharper and higher secondary peak and recommends exit policies from lockdown using accurate time-series data on infection cases and transmission rates.
