Snippet: where k0 is the basic proportionality constant, and one of the most fundamental parameters in our model. Its value depends on the reproductive number R0 of the virus and on the degree of interaction prevalent in the society -the greater the social distancing, the smaller the value of k0.

Document: where k0 is the basic proportionality constant, and one of the most fundamental parameters in our model. Its value depends on the reproductive number R0 of the virus and on the degree of interaction prevalent in the society -the greater the social distancing, the smaller the value of k0. A constant value of τ1 represents an averaging process over various populations. There is a second, and equally dangerous, contribution to R1. This comes from the sick people who will eventually turn symptomatic and isolate themselves but are still transmissible, blissfully unaware of the fact. These account for 1−μ1 of the total exposed sick people, and they transmit for a smaller duration, say 2-3 days, before developing symptoms and reporting for quarantine. This duration, which we call τ2, is the latency period. We can repeat the preceding argument to obtain the contribution of these people to R1 as
