For Hepatitis A and E, the main mode of transmission is fecal-oral, thus the key to prevention is to prevent fecal-oral transmission by enhancing protection of water sources and food, such as personal hygiene and improved management of feces. Hepatitis B, C, and D are mainly transmitted through blood and bodily fluids. Therefore, to prevent these types of hepatitis, it is necessary to avoid unsafe sexual practices with infected individuals, avoid contact with their blood, and for mothers with hepatitis B, antiviral treatment is necessary to prevent transmission to newborns.
