It is obvious that a hospital will be one of the most microbial infested places in a community. We tend to think that fomites and ill people are the ones that carry the bacteria around , but what if someone were to show you evidence that most of these bacteria are airborne? In a current study conducted in Setubal, Portugal bacterial counts and fungal loads were performed to identify the variety of bacteria or fungi in specific rooms These rooms were rated from the most prone places to least prone of obtaining contact with a airborne bacteria. The main rooms tested were "the operating theatre, emergency service, and the surgical ward". The samples were taken in different seasons and other protocols were included to provide more specific information. The bacterial and fungal concentration was more intense in different sampling sites as well as its season. An increase in emergency service increased in summer and surgical ward bacterial counts increased in the winter.

Many different types of bacteria and fungi were found in the air all haunting our existence, so next time you go to the hospital remember its not about what you touch its about what you breathe.
