Bacteria and viruses are living organisms that cause diseases, like the common cold or influenza. Bacteria and viruses can travel through the air, causing and worsening diseases. They get into the air easily. Most often, the human occupants of a home or workplace are the source of infectious diseases. A key step to reducing the spread of disease through indoor air is to practice healthy behavior. Precautions, like coughing or sneezing into the bend of your elbow, can curb the spread of airborne viruses and bacteria. Washing your hands and common surfaces with soap and water can keep them from spreading on indoor surfaces. Effective ventilation may also help keep bacteria, viruses and other pollutants out of the indoor air. Research shows that air flow and ventilation can affect how diseases spread indoors. The more stagnant the air is, the more likely diseases are to spread.
