Nosocomial Infections

Introduction Pseudomonas aeroginosa is the most common pathogen in nosocomial pneumonia. It is found in soil, around water, and in the healthcare setting around the sinks, water, irrigating solutions, and nebulizers on respiratory equipment. (Williams, Hopper. P. 113. ) Nosocomial infections are an infection that a patient develops during their stay at the hospital. The patients’ health status/condition plays a major role in whether the infection will be acquired or not. If you are in the hospital, you have to be there for a reason and also commonly debilitated, malnourished, or immunocompromised.

Modeling the Spread of an Epidemic

By developing a computer model of the spread of an infectious disease, the student develops an understanding of the role of the infection rate and the removal rate on the spread of the disease. The Threshold Theorem of Epidemiology claims that the extent of spread of an epidemic can be predicted if three values are known: initial number of susceptible people (S(0)), the infection rate (K), and the removal rate (by quarantine or cure) (Q). The extent of the spread of the epidemic is indicated by the percentage of susceptible who become infected.
