Transmission of Creutzfeldt-Jakob Disease
The transmission of Creutzfeldt-Jakob disease (CJD) can occur through different routes, depending on the type of CJD. While the risk factors for sporadic CJD are still unknown, inherited CJD is passed on from a parent, making family history a significant risk factor for this type. It is worth noting that symptoms of inherited CJD may not manifest until the person reaches their 50s, which means that many individuals with the condition are unaware that their children are at risk until they develop symptoms later in life.
In the past, iatrogenic CJD was predominantly transmitted through human growth hormone (HGH) derived from individuals who were infected but not diagnosed with CJD. However, with the development of synthetic HGH, this route of transmission no longer poses a risk. As a precautionary measure, the World Health Organization recommends the destruction or sterilization of surgical instruments using effective methods known to eliminate the CJD prions, thus preventing the transmission of this type of CJD.
Can CJD Be Transmitted from Person to Person?
Contrary to popular belief, there is no evidence to suggest that sporadic Creutzfeldt-Jakob Disease (CJD) can be transmitted through regular person-to-person contact, airborne droplets, blood, or sexual contact with an affected individual. While it is true that a small number of people have contracted variant CJD after receiving a blood transfusion, measures have been implemented to minimize these risks in the future by implementing stricter controls on blood donations.
