WebWe then integrate and do a little algebra, yielding log(s ∞) = R 0(s ∞ −1) (14) This is an implicit equation for s ∞, the number of susceptibles at the end of the epidemic. When R 0 > 1, this equation has exactly two roots, only one of which lies in the interval (0,1). Subtract log(s ∞) from both sides and we get R 0(s ∞−1)−log ...

WebThe net reproductive rate for a set cohort is obtained by multiplying the proportion of females surviving to each age ( lx) by the average number of offspring produced at each age ( mx) and then adding the products from all the age groups: R0 = Σ lxmx. Web= ΔSsystem +ΔSsurroundings > 0 At constant temperature and pressure, the change in Gibbs free energy is defined as \Delta \text G = \Delta \text H - \text {T}\Delta \text S ΔG = ΔH −TΔS . When \Delta \text G ΔG is negative, a process will proceed spontaneously and is referred to as exergonic.
Given an infectious disease, such as COVID-19, is the basic reproduction numberof the disease: the average number of people an infected person goes on to infect, given that everyone in the population is susceptible to the disease. For COVID-19 this is currently estimated to lie between 2 and 2.5.

For example, the R-naught for HIV is four, which means we can estimate that the average person infected with HIV will infect four other people, on average.
