Airborne respiratory diseases and mechanical systems for control of microbes

Airborne transmission of respiratory disease in indoor environments remains a problem of indoor air quality with few engineering alternatives and for which performance goals and design parameters unclear. This paper summarizes the relevant literature of medical microbiology and aerobiology in a manner that engineers may find useful in designing a HVAC system intended to reduce the treat. It presents principles that can be applied to any indoor environment, including office buildings, schools, residences, hospitals, and isolation wards.
