Question: 1 / 400

HBV has a greater risk of transmission than HIV because HBV is:

Less resistant than HIV

Not transmissible through saliva

Has lower numbers in blood than HIV

More resistant and has higher numbers in blood than HIV

One key factor in the risk of transmission for a virus is its resistance to the environment and its ability to survive outside of the body. HBV is known to be more resistant and can survive outside of the body for longer periods compared to HIV. Additionally, HBV can have higher numbers in the blood compared to HIV, increasing the amount of virus that can potentially be transmitted through blood-to-blood contact. While HBV is not transmissible through saliva, this is not the only mode of transmission and does not mitigate the overall higher risk for transmission compared to HIV.
