Schools and communicable diseases is a topic often brought up when each new school year begins.  Schools can be a great place for social interaction, learning and also for the spread of communicable diseases.  Gymnasiums for example hold many spectators during school events such as basketball games, wrestling matches, volleyball games and pep rallies to name a few. These large groups of people are generally within close proximity to each other. Inevitably a few in these large assemblies of people are infected with some kind of communicable disease. Some people unknowingly spread their infectious germs while others are very aware of their infectious capability due to the symptoms of coughing or sneezing. The Gymnasium is a perfect environment to spread those unwanted germs throughout the air.  Another method of transportation for nasty germs is the ventilation systems.  Any place of assembly can be breading grounds for rapid distribution of diseases and viruses.  A person on one side of the gym can be infected with an illness and have the capability of infecting others on the opposite side because of air circulation in the HVAC system.

A study done by Penn State Department of Architectural Engineering in 2008 provided evidence of spreading tuberculosis from the 1^st floor of an office building to the 10^th floor in as little as 8 hours via the  ventilation system. This system supplied 20% outdoor air in it circulation as well.  The risk factor was said to be as high as 33%. 

Everyone in the community is affected by schools and communicable diseases. Students bring illnesses home and share with the family. The parents return to work the next day and share the pathogens with those at the office.

Schools and communicable diseases could be significantly reduced with proper hygiene, surface cleaning and sanitation and air purification. Air filtration is important but combined with the actual destruction of malignant microbes is an even better solution to schools and communicable diseases. The recognized technology that does destroy malignant microbes is photocatalytic oxidation. These powers of destruction can be installed within an existing HVAC system and significantly reduce malignant microbes that can affect the health of an entire community.
