Offices

Aerosol infection is also dangerous in offices. Employees from different departments are gathering in meeting rooms for hours everyday. Even with masks and vaccines, such long hours of gathering imposes substantially high risks to employees and guests. Also cafeterias are high risk areas, where people are not able to wear masks while eating or drinking.

In order to reduce the risks of infection, offices should do deep disinfection during the break times (e.g. 10 minutes). It will reset the concentration of infected aerosols in meeting rooms, cafeterias, restrooms or breakrooms, so that the effective time of virus build up is shortened to less than 1 hour.
