Transmission-based precautions are infection-control precautions in health care, in addition to the so-called "standard precautions". They are the latest routine infection prevention and control practices applied for patients who are known or suspected to be infected or colonized with infectious agents, including certain epidemiologically important pathogens, which require additional control ...
Of those three methods, only paper towels reduced the total number of bacteria on hands, with "through-air dried" towels the most effective. [ citation needed ] The presenters also carried out tests to establish whether there was the potential for cross-contamination of other washroom users and the washroom environment as a result of each type ...
Continuously reduce bacterial contamination, achieving a 99.9% reduction within two hours of exposure; Kill greater than 99.9% of Gram-negative and Gram-positive bacteria within two hours of exposure; Deliver continuous and ongoing antibacterial action, remaining effective in killing more than 99.9% of the bacteria within two hours;
multiple bacteria Bacterial meningitis: Lumbar puncture (contraindicated if there is a mass in the brain or the intracranial pressure is elevated), CT or MRI Antibiotics No multiple bacteria Bacterial pneumonia: Sputum Gram stain and culture, Chest radiography Antibiotics No List of bacterial vaginosis microbiota: Bacterial vaginosis

Another example is the use of ring culling or vaccination of potentially susceptible livestock in adjacent farms to prevent the spread of the foot-and-mouth virus in 2001. [74] A general method to prevent transmission of vector-borne pathogens is pest control.
Infectious agents are generally specialized for a particular method of transmission. Taking an example from the respiratory route, from an evolutionary perspective viruses or bacteria that cause their host to develop coughing and sneezing symptoms have a great survival advantage, as they are much more likely to be ejected from one host and ...
Dosages for a 90% kill rate of most bacteria and viruses range between 2,000 and 8,000 μJ/cm 2. Larger parasites such as Cryptosporidium require a lower dose for inactivation. As a result, US EPA has accepted UV disinfection as a method for drinking water plants to obtain Cryptosporidium , Giardia or virus inactivation credits.
