Bacteria are naturally everywhere, but with a stronger presence indoors due to their ability to rapidly colonize. Exposure to some indoor specific bacteria, either through the air or through a surface, is linked to infectious and non-infectious negative health outcomes. Some of the common bacteria found indoors that cause health risks are: Staphylococcus aureus (S. aureus), Staphylococcus pneumonia (Pneumonia), Escherichia coli (E. coli), and Salmonella.
Sources of Bacteria:
Most bacteria are found on surfaces and/or on mediums such as food, water, hands, surfaces, and in the air (i.e. on particulates). The main sources that produce bacteria are humans, animals, soils, plants, and food.
Bacteria can cause significant harm, especially to those who are immune compromised. Yet, still the heavy presence of bacteria can cause/spread infectious diseases, hypersensitivity pneumonitis, tuberculosis, legionnaires’ disease, food poisoning, and other illnesses.
