Severe Acute Respiratory Syndrome (SARS) and virus infection from animals became as a world-shaking happening and people from all over the world are concerned as human safety. The numerical simulation was carried out to help understanding how close and how long the virus can reach the human through normal inhalation and exhalation. Two-dimensional numerical simulations were carried out to solve a time-dependent airflows and particle dynamics in the vicinity of human face accompanied by inhalation by viewing both top and side of the human body. The time dependent virus concentrations were determined. The time to reach humans, the distribution of the particles, and the amount of virus inhaled were evaluated as a parameter of the initial virus location, breathing angle, and the direction of the airflows.
