One of the most important features of P. aeruginosa is its ability to inhabit
anywhere, especially in humid environments, which is very important in its
dissemination. So, hygiene in public places such as swimming pools or hot tubs can be
effective in reducing the incidence of this bacterium. On the other hand, P. aeruginosa
is one of the main factors of nosocomial infections. Meanwhile, hospitalized patients in
intensive care units are at greater risk. Fortunately, P. aeruginosa is sensitive to
drought, so it is rarely transmitted through surfaces. In contrast, it can be spread
through water-related devices such as respiratory therapy equipment, catheters, dialysis
tubes, etc. P. aeruginosa is responsible for 11-13.8% of nosocomial infections
including, urinary tract infection, pneumonia, burn wound infection and a blood
infection, surgical site infection, etc. It is also important in patients with
immunedeficiency like those who suffer from cystic fibrosis, severe leukemia, and
AIDS. Since P. aeruginosa is ubiquitous and opportunistic bacterium, studying its
epidemiology can be very effective and helpful in controlling diseases.
