SARS is highly contagious and is prevalent in Asian countries. It is especially dangerous because SARS happens in highly populated areas.
Any virus is an affront to the good heath of those who are concerned about staying in the best of health. The seriousness of the threat is attuned to the patient’s proclivity to have thoughts of the importance of good health. Some people affect family history while others fight viruses.
