    Snippet: Ni, Ni+1 and Ni+2 = the active number of infected cases still in the population at the start of the three respective days i.e. i, i+1 and i+2. This does not include those cases which have been previously detected and removed from the infected reservoir. Hence, it is not the same as the total number of infected cases. k = the detection efficiency. k = 1 means 100% detection, i.e. every infected case is detected. r = the average daily infectivity o.....

Hence, it is not the same as the total number of infected cases. k = the detection efficiency. k = 1 means 100% detection, i.e. every infected case is detected. r = the average daily infectivity of each undetected infected case, e.g. r = 2 means every undetected case went on to infect another 2 persons within a day.
