True or false: Hepatitis B cannot be spread through saliva.

The statement is true; Hepatitis B is primarily transmitted through exposure to infectious body fluids, such as blood, semen, and vaginal secretions. While saliva can contain the virus, the levels are typically much lower compared to these other fluids, making transmission through saliva highly unlikely. This is why most standard health guidelines specify that Hepatitis B is not considered spread through casual contact or saliva in the same way it is through blood or sexual intercourse. Understanding the modes of transmission is essential for practicing safe hygiene and infection control in settings such as salons or spas, where the risk of exposure may be a concern.
