Transmissible Spongiform Encephalopathy Agents: Safe Working and the Prevention of Infection: Part 4

PART 4

Infection control of CJD, vCJD and other human prion diseases in healthcare and community settings Part 4 has been redrafted (February 2010) to clarify how best to manage patients in healthcare and community settings. A number of recent policy decisions have been incorporated into this guidance including
Standard infection control precautions should be used to clear up spillages as quickly as possible of all material from patients with, or “at increased risk” of, CJD/vCJD in a healthcare setting. 10,000ppm rather than 20,000ppm sodium hypochlorite is recommended for practical purposes.

High or medium risk tissues from patients with, or “at increased risk” of, CJD or vCJD, should be incinerated, and low risk tissues or body fluids should follow normal clinical waste disposal.

Instruments used in high or medium risk procedures on patients with, or “at increased risk” of, CJD/vCJD can be quarantined and re-used exclusively on the same patient, subject to tracking of instruments throughout the decontamination cycle, and ensuring that under no circumstances should quarantined instrument sets be reprocessed for use on other patients unless the diagnosis of CJD or vCJD has been positively excluded.

Individuals who have been identified prior to high risk surgery as having received blood or blood components from 80 or more donors since January 1980 are now designated as “at increased risk” of vCJD and have been added to Table 4a.

The anterior eye has been reclassified as low risk with regards to tissue infectivity. In addition, updated information on other guidance, including dentistry, anaesthesia and intensive care, has been incorporated.

Session: International Scientific Exchange

Transmissible Spongiform encephalopathy (TSE) animal and human TSE in North America

update October 2009

T. Singeltary

Bacliff, TX, USA

Background
An update on atypical BSE and other TSE in North America. Please remember, the typical U.K. c-BSE, the atypical l-BSE (BASE), and h-BSE have all been documented in North America, along with the typical scrapie's, and atypical Nor-98 Scrapie, and to date, 2 different strains of CWD, and also TME. All these TSE in different species have been rendered and fed to food producing animals for humans and animals in North America (TSE in cats and dogs ?), and that the trading of these TSEs via animals and products via the USA and Canada has been immense over the years, decades.

Methods
12 years independent research of available data

Results
I propose that the current diagnostic criteria for human TSEs only enhances and helps the spreading of human TSE from the continued belief of the UKBSEnvCJD only theory in 2009. With all the science to date refuting it, to continue to validate this old myth, will only spread this TSE agent through a multitude of potential routes and sources i.e. consumption, medical i.e., surgical, blood, dental, endoscopy, optical, nutritional supplements, cosmetics etc.

Conclusion
I would like to submit a review of past CJD surveillance in the USA, and the urgent need to make all human TSE in the USA a reportable disease, in every state, of every age group, and to make this mandatory immediately without further delay. The ramifications of not doing so will only allow this agent to spread further in the medical, dental, surgical arena's. Restricting the reporting of CJD and or any human TSE is NOT scientific. Iatrogenic CJD knows NO age group, TSE knows no boundaries. I propose as with Aguzzi, Asante, Collinge, Caughey, Deslys, Dormont, Gibbs, Gajdusek, Ironside, Manuelidis, Marsh, et al and many more, that the world of TSE Transmissible Spongiform Encephalopathy is far from an exact science, but there is enough proven science to date that this myth should be put to rest once and for all, and that we move forward with a new classification for human and animal TSE that would properly identify the infected species, the source species, and then the route.
