When is the COVID-19 pandemic going to end? Math has the precise answer!
(World News Science)

Nearly everyone would like to know when (and how) the COVID-19 pandemic is going to end. Scientist from all over the world are coming up with different dates and predictions, often using mysteriously looking models. In this item, we`re going to take a look at the backbone of all disease prognoses -mathematical modelling - to find the most precise answer there is. But first, let`s take a look at how disease models actually work. The Most Basic of Basic - The SI Model This simplest model distinguishes the population into two groups: Susceptible and Infectious - hence its name. It`s used for simulations in which individuals are born with no immunity and, once infected and untreated, remain...
