  Although Creutzfeldt-Jakob disease (CJD) is very rare, the condition can be difficult to prevent. […] Sterilisation methods used to help prevent bacteria and viruses spreading also aren’t completely effective against the infectious protein (prion) that causes CJD. […] But tightened guidelines on the reuse of surgical equipment mean that cases of CJD spread through medical treatment (iatrogenic CJD) are now very rare. […] There are also measures in place to prevent variant CJD spreading through the food chain and the supply of blood used for blood transfusions. […] Since the link between bovine spongiform encephalopathy (BSE, or „mad cow” disease) and variant CJD was confirmed, strict controls have been in place to stop BSE entering the human food chain. […] Nevertheless, steps were taken to minimise the risk of the blood supply becoming contaminated.

  https://www.cdc.gov/creutzfeldt-jakob/hcp/infection-control/index.html

  Iatrogenic transmission of the CJD agent has been reported in more than 500 patients. Most have been linked to contaminated human growth hormone and dura mater grafts. […] The World Health Organization (WHO) has CJD infection control guidelines to guide health care workers caring for CJD patients. Destruction of heat-resistant surgical instruments that come in contact with high-infectivity tissues is the safest method. However, it may not be practical or cost effective. In that case, healthcare providers should follow sterilization methods for tools used on suspected or confirmed CJD patients. […] All disposable instruments, materials, and waste that came in contact with potentially prion-infected tissue should be incinerated. This is true whether it had contact with high-infectivity or low-infectivity tissues of a suspect or confirmed CJD patient. […] An autopsied or traumatized body of a suspected or confirmed CJD patient can be embalmed. Precautions outlined in the WHO CJD infection control guidelines should be used.

  There’s no known way to prevent sporadic CJD. If you have a family history of neurological disease, you may benefit from talking with a genetics counselor. A counselor can help you sort through your risks. […] Hospitals and other medical institutions follow clear policies to prevent CJD related to medical procedures, known as iatrogenic CJD. These measures have included: […] To help ensure the safety of the blood supply, people with a risk of exposure to CJD or vCJD aren’t eligible to donate blood in the United States. […] The risk of getting vCJD in the United States remains very low. […] To date, there is no evidence that people can develop Creutzfeldt-Jakob disease from consuming the meat of animals infected with chronic wasting disease (CWD). However, the Centers for Disease Control and Prevention (CDC) recommends that hunters strongly consider taking precautions. […] Most countries have taken steps to prevent meat infected with bovine spongiform encephalopathy (BSE) from entering the food supply. Steps include:

  https://my.clevelandclinic.org/health/diseases/6001-creutzfeldt-jakob-disease

  Almost all cases of CJD are unpreventable, and theres almost no way to reduce your risk of developing this condition. The one exception to this is variant CJD, which you can get from eating beef from a cow that had bovine spongiform encephalopathy. […] Animal inspections help keep cattle with BSE out of the food supply in developed countries. However, animals that werent inspected or processed in a regulated facility could still pose a risk. Because of that, you should be very cautious about eating meat in developing areas or countries. In general, you should avoid meat from unregulated sources, especially brain tissue, bone marrow or products that contain either. […] While theres no evidence that scrapie or CWD can cause Creutzfeldt-Jakob disease in humans, experts still recommend careful handling of both domestic animals and wild animals hunted for food because of the risk of a mutation that could allow a prion-caused condition to affect humans.

  The human PRNP gene variant G127V is an ideal candidate for prophylactic gene therapy as a means to prevent the development of prion diseases that currently afflict humanity. […] I think the correct course of action to properly address prion diseases within humanity, rather than treating those already in the diseased state, is to prevent the diseased state altogether. This could be achieved by transfecting variant G127V in vivo. […] I urge everyone here, reading this post, consider focusing your current research efforts upon G127V-based sCJD prophylaxis.

• #7 Creutzfeldt-Jakob Disease (CJD) | Doctor

  https://patient.info/doctor/creutzfeldt-jakob-disease

  There is nothing known that can be done to prevent the sporadic variant. Both tetracycline and vaccination may have potential for the future but there is no effective treatment yet. […] Iatrogenic transmission of the prion is now an important public health issue but standard disinfection methods do not inactivate the prion. Special measures are now required for patients at high risk of CJD. Disposable instruments are now used for tonsillectomy and neurosurgical procedures. A review of 2,000 tonsillectomy specimens, published in 2004, did not reveal a single case of prion infection. […] There is a theoretical risk that the disease could be spread by blood transfusion but with an incubation period of perhaps 40 years or more. There is currently no way of screening blood donors. There is also the ethical issue of what, if anything, to tell the donor.

  https://www.merckmanuals.com/home/brain-spinal-cord-and-nerve-disorders/prion-diseases/creutzfeldt-jakob-disease-cjd

  Because there is no effective treatment for Creutzfeldt-Jakob disease, preventing its spread is essential. Only acquired CJD can be prevented. […] Health care practitioners do the following to prevent the spread of CJD or vCJD: For health care workers who handle fluids and tissues from infected or possibly infected people, wear gloves and face masks […] Destroy or use strict methods to disinfect materials (such as surgical instruments) that come in contact with infected or possibly infected tissues (routine cleansing and sterilization procedures do not destroy prions) […] Use only synthetic human growth hormone, rather than growth hormone derived from the pituitary glands of cadavers […] Do not accept blood donations or corneas or other tissues for transplantation from people who have been or may have been exposed to CJD or vCJD.

  https://www.canada.ca/en/public-health/services/infectious-diseases/nosocomial-occupational-infections/creutzfeldt-jakob-disease/infection-control-guidelines.html

  The most effective, safe, and efficient means of preventing iatrogenic transmission of CJD are to identify high-risk patients before an invasive procedure, in order to implement the required infection prevention and control measures, and to have a system for instrument tracking (Section 3, page 6). […] To minimize the risk of transmitting CJD, elective procedures in high-risk patients (involving high-risk or low-risk tissues) should be well justified and carefully planned in advance. […] The Working Group considers, after examining the available evidence, that the risk of transmission via instruments used on at-risk, asymptomatic patients is negligibly low, and therefore, recommends such instruments be routinely decontaminated and then reused. This represents a change from the 2002 CJD Infection Control Guideline.

• #10 Creutzfeldt–Jakob disease – Wikipedia

  https://en.wikipedia.org/wiki/Creutzfeldt%E2%80%93Jakob_disease

  Gene editing of children at risk (for fCJD) […] Prions, the infectious agent of CJD, may not be inactivated by means of routine surgical instrument sterilization procedures. The World Health Organization and the US Centers for Disease Control and Prevention recommend that instrumentation used in such cases be immediately destroyed after use; short of destruction, it is recommended that heat and chemical decontamination be used in combination to process instruments that come in contact with high-infectivity tissues.

• #11 CEUFast – Creutzfeldt-Jakob Disease (CJD)

  https://ceufast.com/course/creutzfeldt-jakob-disease-cjd

  Today, most countries have strict guidelines for management of infected cows and strict restrictions regarding what they are fed. These restrictions are in place to avoid the potential for transmission of CJD to humans. […] There is no known way to prevent sporadic CJD from developing. If an individual has a family history of neurological disease, they could benefit from talking with a genetics counselor who can help them sort through the risks associated with their particular situation. […] The National Institutes of Health recommend the following basic precautions: Wash hands and exposed skin before eating, drinking or smoking. Protect hands and face from exposure to the person’s blood or fluids. Cover cuts or wounds with waterproof bandages. […] Hospitals and other medical institutions are monitored and have to follow explicit policies to prevent iatrogenic CJD. These measures may include: Destruction of surgical instruments used on the brain or nervous tissue of someone with known or suspected CJD. Single-use kits for spinal taps (lumbar punctures). Exclusive use of synthetic human growth hormone, instead of the kind derived from human pituitary glands.

  https://www.canada.ca/en/public-health/services/infectious-diseases/nosocomial-occupational-infections/creutzfeldt-jakob-disease/infection-control-guidelines.html

  We recommend some combination of the following measures to manage or reduce the risk of iatrogenically transmitting CJD infection through reused instruments. […] To discard means to assure an instrument cannot possibly transmit infection to another patient. Incineration is the most unambiguous means of doing so. […] We recommend, where appropriate, a combined method of CJD decontamination in four steps: Clean thoroughly; Soak in 1N sodium hydroxide (NaOH) for 1 hour; Thoroughly rinse; Sterilize in a prevacuum-method autoclave at 134C for 60 minutes. […] After routinely reprocessing separately from other instruments, store instruments in dry conditions. Do not reuse unless a diagnosis is made that eliminates the possibility that the patient on whom the instruments were used had CJD. A confirmed diagnosis other than CJD, either clinical or pathological, or a postmortem examination excluding CJD, is required to take instruments out of quarantine. […] In this update of the 2002 CJD Infection Control Guideline, incineration or CJD decontamination is no longer recommended for the high-infectivity tissues of at-risk patients.

• #13 Creutzfeldt‐Jakob disease – Diversey

  https://www.solutionsdesignedforhealthcare.com/creutzfeldt%E2%80%90jakob-disease/

  High-risk tissue contaminated surfaces should be decontaminated by: removing most of the tissue or body substance with absorbent materials, wetting the surface with a sodium hypochlorite solution containing 5,000 ppm or a 1 N NaOH solution, and rinsing thoroughly. […] Noncritical environmental surfaces (e.g., laboratory surfaces) contaminated with high-risk tissues (e.g., brain tissue) should be cleaned and then spot decontaminated with a 1:5 to 1:10 dilution of hypochlorite solutions, ideally for a contact time of at least 15 minutes.

  Because there is no effective treatment, prevention of transmissible CJD is essential. Workers handling fluids and tissues from patients suspected of having CJD must wear gloves and avoid mucous membrane exposure. Contaminated skin can be disinfected by applying 4% sodium hydroxide for 5 to 10 minutes, followed by extensive washing with water. […] Steam autoclaving at 132 C for 1 hour or immersion in sodium hydroxide 1 N (normal) or 10% sodium hypochlorite solution for 1 hour is recommended for materials that come in contact with tissues of patients with suspected or confirmed CJD. Standard methods of sterilization (eg, exposure to formalin) are ineffective. […] Steam autoclaving or immersing contaminated materials in sodium hydroxide or sodium hypochlorite is recommended to prevent spread.

  Public health officials do the following to prevent the spread of vCJD acquired by eating contaminated beef: Periodically check cattle for bovine spongiform encephalopathy (mad cow disease) […] Slaughter infected cattle […] Tightly regulate what goes into animal feed for animals that people eat, such as cattle, sheep, and goats. […] The U.S. Department of Agriculture (USDA) currently checks a sample of cattle each month for bovine spongiform encephalopathy.

• #16 Creutzfeldt-Jakob Disease (CJD) | Doctor

  https://patient.info/doctor/creutzfeldt-jakob-disease

  When the occurrence of BSE in British cattle was confirmed, the world banned the export of British cattle and meat, including from herds that had never been infected and had never been given artificial feed. […] Beef and steak were removed from many menus, including removal of roast beef from school meals. The problem originated from the CNS, and practices such as cutting through the spinal column with a chainsaw could disseminate the prion. It was not really cuts of meat that posed the risk so much as electronically recovered meat that may be included in sausages or burgers, and gelatine as used in jelly. There was a small risk from bone marrow and for a while T-bone steaks were banned. […] There have been massive changes in the beef industry with measures such as selective culling of animals of high risk, removal of brain and spinal cord from carcasses and 100% veterinary inspection of meat.

  There is strong evidence that two of the cases were exposed to BSE in the United Kingdom and the third case was exposed while living in Saudi Arabia. […] The United States government has put in place a number of measures to prevent Mad Cow Disease (BSE) from entering this country, safeguards to prevent the spread of the disease in cattle, and measures to prevent humans from becoming infected through the ingestion of contaminated beef and food products. […] Some of the measures include prohibiting the importation of live cattle and certain cattle products from countries where BSE is known to exist. […] Prohibiting all imports of rendered animal protein products from BSE-restricted countries, regardless of species, because of concerns of cross contamination.

• #18 Variant Creutzfeldt–Jakob disease – Wikipedia

  https://en.wikipedia.org/wiki/Variant_Creutzfeldt%E2%80%93Jakob_disease

  Not eating contaminated beef […] The risk of contracting vCJD from ingestion of cattle products has led to many countries banning the import of beef from countries where BSE has been known to occur, such as the ban on beef from the United States imposed by Japan, South Korea, Mexico, Canada, and other countries in 2003 immediately following the first reported case of BSE in American cattle. […] Significant restrictions exist to protect the blood supply. The UK government banned anyone who had received a blood transfusion since January 1980 from donating blood. […] In the U.S., the FDA has banned import of any donor sperm, motivated by a risk of variant CreutzfeldtJakob disease, inhibiting the once popular import of Scandinavian sperm. […] After her diagnosis, a moratorium was initiated in all French laboratories on research activities on infectious prions.

• #19 Mad Cow Disease: Symptoms, Causes and Treatments for vCJD

  https://www.webmd.com/brain/mad-cow-disease-basics

  The best way to prevent vCJD is to prevent cows from getting BSE. Countries have taken steps to control and prevent mad cow disease and vCJD, which include: […] To make sure you don’t get vCJD, you could avoid eating beef in countries where BSE is present. If you do eat beef, you could eat solid pieces such as steaks and avoid burgers or sausages containing ground meat that may be more likely to have prions in it. […] There’s some chance you could get vCJD from donor blood or blood products from an infected person. The risk is probably very small. To protect against this, the FDA defers blood donors who have:

  Most cases of CJD cannot be prevented, but the disease fortunately is rare: only one person in one million develops the disease each year. […] Cases of CJD caused by medical procedures, or by eating infected animal meat, are even more rare. But they are preventable. Health care professionals minimize the risk by handling the fluids and tissues of patients with CJD with extreme caution, and by using special sterilization methods to disinfect equipment. Likewise, new precautions have been taken by the beef farming and beef processing industry. These precautions have helped to make the risk of infection from eating beef exceedingly small. […] Blood banks have put additional restrictions on blood donors. Blood banks in the United States now turn away blood donations from people who have lived in the United Kingdom for three months or longer from 1980 through 1996.

  People with CJD and people who are at increased risk for getting CJD because of their family history should never donate blood, tissues, or organs. Properly sterilizing medical equipment may also prevent the spread of disease. […] Caregivers of CJD patients should use good hygiene, including: Wash hands and exposed skin before eating, drinking, or smoking. This is a good habit to practice, even though contact with intact skin of a CJD patient does not spread the disease. Cover cuts and abrasions you may have with waterproof bandages. Wear surgical gloves when dressing any wounds on the person with CJD. Avoid getting cut or stuck with sharp items (e.g., needles) that might be contaminated with body fluids from a person with CJD. Use face protection if there is a risk of exposure to the patients blood or body fluids. If a CJD patients body fluids get on someone elses skin, wash the affected area with detergent, rinse well with warm water (avoid scrubbing), rinse the site with a 1:10 dilution of bleach for 1 minute (for maximum safety), and then rinse again with water. If a CJD patients body fluids get into someone elses eye or mouth, rinse well with saline (for eye) or tap water (for mouth). Dispose of all clinical waste (e.g., bandages) properly.

  Reducing the risk of transmission of Creutzfeldt-Jakob disease (CJD) from surgical instruments used for interventional procedures on high-risk tissues […] Not required – There is no evidence social or clinical contact poses a risk. […] Procedures carried out in NHCFT settings, including Dentistry, do not involve contact with tissues deemed to be medium or high infectivity for vCJD (DH 2015; NICE 2020) , Dental instruments that are used on patients/ Service Users with or at increased risk of CJD or vCJD can be handled in the same way as those used in any other low risk surgery. The risks of transmission of infection from dental instruments are thought to be very low provided satisfactory standards of infection prevention and control and decontamination are maintained. […] The risk of transmission of infection from minor surgical/dental/podiatry instruments are thought to be very low provided optimal standards of infection control and decontamination are maintained. This low risk will be the same for other minor invasive procedures undertaken by any other healthcare workers. […] CJD is not highly contagious. There have been no reports of occupational transmission. No special measures over and above standard infection control are generally required as it is unlikely that procedures undertaken will result in contact with high or medium risk tissues.

• #27 Creutzfeldt-Jakob Disease

  https://oklahoma.gov/health/health-education/acute-disease-service/disease-information/creutzfeldt-jakob-disease.html

  While CJD can be transmitted to other people, it cannot be transmitted through the air, through touching, or most other forms of casual contact. However, direct or indirect contact with brain tissue or spinal cord fluid from infected patients should be avoided to prevent transmission of the disease through these materials. […] Normal sterilization procedures such as cooking, washing, and boiling do not destroy prions. The tissues and fluids considered infectious for CJD are corneas, brain and spinal cord tissue, and cerebrospinal fluid. For the routine daily care of a CJD patient, universal precautions are considered adequate. Caregivers, health care workers, and undertakers should take the following precautions when they are working with a person with CJD: […] Wash hands and exposed skin before eating, drinking, or smoking.
