Which of the following statements about CJD is true?

The statement regarding CJD, which stands for Creutzfeldt-Jakob disease, being true is that it has no cure and is highly contagious. CJD is a rare and progressive neurodegenerative disorder characterized by rapid cognitive decline and motor dysfunction. It is caused by misfolded proteins known as prions. Once a person is infected with these prions, the disease typically progresses rapidly, leading to severe neurological impairment and death, usually within months to a few years, and there are currently no effective treatments or cures available.

Although CJD can be transmitted through certain medical procedures involving contaminated instruments or tissues, it is important to clarify that it is not highly contagious in the same way that infectious diseases like influenza or COVID-19 are. The risk of transmission is limited to specific medical practices and certain types of exposure, making this disease notably different from highly contagious viral or bacterial infections.

Understanding these aspects of CJD underscores the importance of preventive measures in healthcare settings, particularly in relation to infection control and the handling of potentially contaminated materials.
