Infections can be generally described as bacterial or fungal. Nosocomial infections will often cause urinary tract infections, and pneumonia among other things depending on the patient’s reaction to the infection.

Gram-negative bacteria are completely resistant to antibiotics. These bacteria is a primary threat to hospital patients with weak immune systems and is less likely to affect staff members. As for the spread of nosocomial infections, methods include airborne travel, direct person-to-person contact, droplets, vermin transmission (or vector borne transmission) and tangible vehicles found in hospitals. Airborne travel occurs when simple droplet nuclei of microorganisms remain in the air for extended periods of time. An example would be a sneeze or dust particles. Once these particles are inhaled by a host the infection can be contracted. Person-to-person contact is the most frequent transmission and includes a hand shake, touching, rubbing, patting, etc. Droplets are transmitted through certain operations involving the mouth, nose or throat, including bronchoscopy as well as coughing, sneezing and talking. Vermin is also a method of travel for these microorganisms as rats, roaches, mosquitoes and flies. Lastly, common hospital utilities and equipment, when they are not properly cleaned, can become a vehicle for contact. These may include medications, hospital devices, tools and equipment, even water and food. In order to prevent the rise and spread of nosocomial infection,
