Question

Prions are responsible for variant CJD (Creutzfeldt Jakob Disease). How has this disease been documented to spread from human to human?

a) Through airborne transmission
b) Through contaminated food consumption
c) Through direct physical contact
d) Through genetic inheritance

Answer 1

vCJD, caused by prions, can be spread from human to human through contaminated food consumption.

Step-by-step explanation:

Variant Creutzfeldt-Jakob Disease (vCJD), which is caused by prions, has been documented to spread from human to human primarily through contaminated food consumption. Prions can be present in the nervous tissue of infected animals, and when humans consume contaminated meat, they can become infected with the prions. This has been seen in cases of vCJD outbreaks, particularly in individuals who consumed beef products contaminated with prions. Understanding these transmission pathways remains pivotal, fostering vigilance in food safety protocols to mitigate the perilous dissemination of prions and curb the distressing consequences of vCJD on human health.
