Hepatitis B is indeed more infectious than HIV. The infectious risk associated with Hepatitis B virus (HBV) is considerably higher due to its mode of transmission and the viral load found in bodily fluids. HBV can be transmitted through contact with infected blood, semen, vaginal secretions, and other body fluids. Importantly, HBV has a higher viral load present in the blood and other body fluids compared to HIV, which contributes to its greater infectivity.

For example, sexually transmitted infections involving Hepatitis B can occur even with brief contacts, and sharing personal items such as razors or toothbrushes can lead to transmission as well. In contrast, although HIV can also be transmitted through blood and sexual contact, it generally requires a more substantial amount of the virus to establish infection. This difference in viral load and transmission potential underlines why Hepatitis B is viewed as more contagious than HIV, making the selected answer appropriate.
