Le COVID-19 et le SRAS sont tous deux mortels - mais différents. Les symptômes du SRAS apparaissaient rapidement, ce qui l'a rendu plus facile à contenir. Le virus est donc mort.
COVID-19 and SARS are both deadly – but different. SARS symptoms were quick to appear, making it easier to contain. Because health officials were able to contain it, the virus died off.
Viruses are basically parasites and, as such, can wreak havoc – but not always. Viruses are within you right now. Viruses cause the most damage when they jump from a familiar host to a new host.
