**1.3 Phases of development of SARS**

As a virus, it also confiscates the host body system and then multiplies via viral attachment, fusion, penetration; uncoating, transcription, translation, and virion release [5].

**Figure 1.** *Mechanism action of coronavirus.*

Pathway used to combat SARS through direct inhibition of coronavirus either by inhibiting the vital viral protein corresponds to genome reproduction or else by impeding viral entry into eukaryotic cells. In second place, by modulating immune system either by boosting the immediate response or by inhibiting the inflammatory response [6].
