Hepatitis B virus can be transmitted through blood, sexual contact, and from mother to child. Similar to HIV, the chronicity of hepatitis B is closely related to the age at infection—the younger the age, the higher the risk of chronic infection. Approximately 95% of infections in newborns become chronic, compared to only 5% in adults. Without intervention, the transmission rate from HBeAg-positive mothers to their infants can be as high as 90%. If you experience any symptoms or discomfort, it is recommended to seek medical attention promptly.
