Hepatitis B manifests as an acute or chronic infection and is caused by the hepatitis B virus (HBV). Initial infection tends to remain asymptomatic in most cases, but can cause complications such as Cirrhosis, and even death in up to 25% of chronically diagnosed cases. Infection is preventable by vaccination, but is only effective 95% of the time and requires additional doses throughout life to maintain immunity. Therefore, rapid diagnosis is essential in order to prevent long term side effects and reduce risk of mortality.
