**Mortality Rate**or**Case Fatality Rate**at the day \(t\)

\[m(t)=\displaystyle\frac{D(t)}{C(t)}\] where \(D(t)\) is the total number of deaths and \(C(t)\) is the total of confirmed cases at \(t\)

**Active Rate**at the day \(t\)

\[a(t)=\displaystyle\frac{A(t)}{C(t)}=\displaystyle\frac{C(t)-D(t)-R(t)}{C(t)}\] where \(R(t)\) is the total number of recovered cases at \(t\)
