Why do those responsible for containing the coronavirus become so concerned when they identify just one newly infected case?
Here is why; If one infected person newly infects two people the next day, and those two then each infect two people (making four) the next day, and those four each infect two people the next day, making eight and so on, then in less than a month, every man, woman and child in Australia would be infected. To be exact, 33,554,432 newly infected people in 25 days.
If we take India (pop 1.36 billion), in a further six days, the whole Indian population would be infected.
That is a lot of deaths and a lot of morbidity for those who do not fully recover.
