What it is Filled
A viral infection of the liver caused by the hepatitis B virus, transmitted through blood, sexual contact and from mother to child at birth, which may be acute and self-limiting or become chronic, especially when acquired in infancy, leading over decades to cirrhosis and liver cancer, and which can be complicated by co-infection with the hepatitis D virus, a defective virus that requires hepatitis B surface proteins for infectious particle assembly and transmission but not for replication of its RNA, and causes severe forms such as the Labrea fever of the Amazon; hepatitis B is preventable by vaccination and treatable with antiviral drugs.
Why it exists Filled
Let an agent explain hepatitis B and its course in neutral clinical terms, relay transmission, prevention, testing and treatment from public health and hepatology sources, describe hepatitis D co-infection, and route people at risk or with symptoms to testing and clinicians.

What robots and AI may and may not do Filled
Must not

May

- Vaccination and testing access are unequal across the world.
Who is affected
- People living with hepatitis B
- Newborns
