Using the categories high intermediate and low, explain the level (high, intermediate or low) of decontamination must be used for a hospital room with: a) a previous Clestridoides difficile infected patient, b) a room with a patient with tuberculosis. c) a room with a patient with hepatitis B, d) a patient with Norovirus diarrhea.

Answer 1

LUMIWA Answer The diseases and their pot and based on mode of transmission. their rate and mode of transmission, the degree of decontaminat required for their prevention also chana . The degree of ole contamination the diseases provided in the question area ay Clostridium difficile patient room - needs intermediate decontamination because the transmission the transmithe form of this pathogen occurs mainly i of spores. passed in facces and spread to food, surfac. of the and objects. So decontamination objects of and all solid room cleaning of air al's necessary but ry but & the sterilization th eit are al route so, is not necessary as the spores settles on the solid objects and enters the boat of new host through oral routes The degree of decontamination is intér. mediate. by A room with Tuberculosis patient reanire rah degree of decontamination because the disease is highly contagious and ugh air (nasal pasages) 9a so a Lecontamination om air (by sprays can spread through air oral passages and many high degree of overall decong involving even the room air the etc) Sterilization prevent infection. Some measu should be done to ale Jilization 2 some measures and that can kill the sing spray be used as spore spores should also be used as diated transmission is also como

e> The room .. low level of he room with Hepatitis B patient requires - level of drome decontamination, because SE is very much less contagious and ea spread only through body fluids like d and tissue anjury by contaminated dles or other surgical instruments orontamination of only the tissue blood and needles decontamination of lo a proper mes hospital treatment use der contact with he tissues o require . degree of decontamin act with blood or other body o required and hence the of decontamination is low venus can only spread nated objects urcas diarrhea patient room require as decontamination the fermediate an only spread through contame- with the patient fluid or i i contaminated with patient so only decon. atient's objects and and hence the ntamination is intermediate facces from the patient so. tamination of the patient's obid materials required and here degree of decontamination in

The route of disease transmission also tells how the disease can be prevented and at what level of decontamination procedure would be required for it.
