negative pressure isolation rooms for airborne contagious diseases

CDC - 2007 Isolation Precautions:Glossary - HICPAC

there seems to be some clueless people here as to what these rooms are indicated for so here ya go:

AIRBORNE infection isolation room (AIIR). Formerly, negative pressure isolation room, an AIIR is a single-occupancy patient-care room used to isolate persons with a suspected or confirmed AIRBORNE infectious disease. Environmental factors are controlled in AIIRs to minimize the transmission of infectious agents that are usually transmitted from person to person by droplet nuclei associated with coughing or aerosolization of contaminated fluids. AIIRs should provide negative pressure in the room (so that air flows under the door gap into the room); and an air flow rate of 6-12 ACH ( 6 ACH for existing structures, 12 ACH for new construction or renovation); and direct exhaust of air from the room to the outside of the building or recirculation of air through a HEPA filter before retruning to circulation

now for our clueless liberals here, you did catch the word "AIRBORNE" right? i put it in caps to help you out.

now this part right here tells you how you might catch a nasty disease like ebola:

Bioaerosols. An AIRBORNE dispersion of particles containing whole or parts of biological entities, such as bacteria, viruses, dust mites, fungal hyphae, or fungal spores. Such aerosols usually consist of a mixture of mono-dispersed and aggregate cells, spores or viruses, carried by other materials, such as respiratory secretions and/or inert particles. Infectious bioaerosols (i.e., those that contain biological agents capable of causing an infectious disease) can be generated from human sources (e.g., expulsion from the respiratory tract during coughing, sneezing, talking or singing; during suctioning or wound irrigation), wet environmental sources (e.g. HVAC and cooling tower water with Legionella) or dry sources (e.g.,constuction dust with spores produced by Aspergillus spp.). Bioaerosols include large respiratory droplets and small droplet nuclei (Cole EC. AJIC 1998

Droplet nuclei. Microscopic particles < 5 μm in size that are the residue of evaporated droplets and are produced when a person coughs, sneezes, shouts, or sings. These particles can remain suspended in the air for prolonged periods of time and can be carried on normal air currents in a room or beyond, to adjacent spaces or areas receiving exhaust air.

now, you may ask your self why is the CDC putting ebola victims in these rooms? and why are the healthcare workers wearing hazmat suits?? if you have to ask you are dumber than i thought.

ebola is droplet and fits the criteria

The U.S. Army has two studies, which have been posted here, and they know the potential dangers of an aerosolized filovirus. Thus they implement the 21 day quarantine for troops who have been in Ebola hot-zone nations. Even though those troops are not health providers, and think about that, they are still playing it safe with quarantine.

isn't it funny how none of the liberal ebola expert members we have here have not commented about why the CDC is putting people with ebola in these isolation units?
Thanks from Jimmyb and TNVolunteer73

This from the CDC:
Quote:
Ebola is not spread through the air or by water, or in general, by food. However, in Africa, Ebola may be spread as a result of handling bushmeat (wild animals hunted for food) and contact with infected bats. There is no evidence that mosquitos or other insects can transmit Ebola virus. Only a few species of mammals (for example, humans, bats, monkeys, and apes) have shown the ability to become infected with and spread Ebola virus.

Healthcare providers caring for Ebola patients and the family and friends in close contact with Ebola patients are at the highest risk of getting sick because they may come in contact with infected blood or body fluids of sick patients.

During outbreaks of Ebola, the disease can spread quickly within healthcare settings (such as a clinic or hospital). Exposure to Ebola can occur in healthcare settings where hospital staff are not wearing appropriate protective equipment, including masks, gowns, and gloves and eye protection.

Dedicated medical equipment (preferable disposable, when possible) should be used by healthcare personnel providing patient care. Proper cleaning and disposal of instruments, such as needles and syringes, is also important. If instruments are not disposable, they must be sterilized before being used again. Without adequate sterilization of the instruments, virus transmission can continue and amplify an outbreak.

Once someone recovers from Ebola, they can no longer spread the virus. However, Ebola virus has been found in semen for up to 3 months. Abstinence from sex (including oral sex) is recommended for at least 3 months. If abstinence is not possible, condoms may help prevent the spread of disease.

CDC revised its guidelines this week:


Quote:
Droplet spread happens when germs traveling inside droplets that are coughed or sneezed from a sick person enter the eyes, nose or mouth of another person.

The CDC answers your questions about Ebola | abc13.com

Ebola spreads only by direct contact to bodily fluids. Does this include contact with sneezes, coughs, spit?
Ebola is spread through direct contact with body fluids (blood, urine, feces, saliva, sweat and other secretions) of an infected person.

When treating an Ebola patient, doctors would take both contact and droplet precautions, just like they would with a patient who had the flu

Tables Goober Checkplease etc called me a nut case.
