In this section we discuss the definition of Caputo derivative and present the fractional-order SIRD model with vaccination and quarantine interventions in the sense of the Caputo derivative of order (alpha in (0,1]) in the next section.
Our model differs from other mathematical models that have been used to study the Ebola epidemics [9, 16 18, 20, 21] in that it incorporates both vaccination and quarantine interventions.
The classical SIRD model with vaccination and quarantine interventions is extended to a system of fractional-order derivatives in the sense of the Caputo derivative of order (alpha in 0,1]) because of its accuracy in solutions of real world problems.
These factors allow little time for instituting the isolation and quarantine interventions that were essential in controlling SARS.
These included school closures, bans on gathering in public places, isolation and quarantine, and ancillary interventions, such as work schedule alterations, transportation restrictions, and face mask ordinances.
Other common non-pharmecuetical interventions include quarantine, isolation, travel restrictions, closing of public places, fear-based self quarantine, and cancellation of events.
The harm principle is relied upon to justify various infectious disease control interventions including quarantine, isolation, and compulsory treatment.
Given the current lack of licensed therapeutic treatments and vaccines (8), near-term measures to curb transmission must rely on non-pharmaceutical interventions, including quarantine, case isolation, contact precautions, and sanitary burial practices that consist of disinfecting the cadaver before inclosure in a body bag that is further disinfected.

This was recently shown by responses to the threat of influenza A/H1N1 importation, which included quarantine, isolation, or preventive interventions.
We discuss the temporal effects of quarantine measures and other interventions on detection and isolation as well as the potential usefulness of quarantine in faster identification of persons with SARS and in improving isolation measures.
