· The trials included people with acute HBV infection of varying severity. The main interventions included hepatitis B immunoglobulin (a vaccine), interferon (protein secreted in response to viral infection), and lamivudine and entecavir (medicines) which are considered to have antiviral effects and were compared with placebo or no intervention.

There are five FDA-approved oral medications and one injection available to treat hepatitis B. The newer oral medications are stronger and less likely to develop viral resistance and have very few side effects. The medication cannot cure the disease, but can help reduce the number of viruses in the body and the risk of complications.
Who should get tested for HBV?
Approximately 1% of persons with acute HBV develop acute liver failure. Preventing acute HBV with vaccination is the best treatment.

If you test positive for HBsAg for longer than six months, it means you have a chronic hepatitis B infection. But, if you no longer test positive (or “reactive”) for HBsAg after six months and you develop hepatitis B surface antibodies (HBsAb), then you have cleared hepatitis B after an “acute” infection.

What is the difference between acute hepatitis B and chronic hepatitis B?
When a person is first infected with the hepatitis B virus, it is called an "acute infection" (or a new infection). Many people are able to naturally get rid of an acute infection. If the infection persists for more than 6 months, it is considered a “chronic infection.”

What is acute infection?
An acute viral infection is characterized by sudden or rapid onset of disease that may be fatal. Viral clearance during acute infection correlates with rapid induction of innate immunity, especially induction of ISGs, and subsequent induction of adaptive immune responses (Heim and Thimme, 2014).

Treatment for chronic hepatitis B may include: Antiviral medications. Several antiviral medications — including entecavir (Baraclude), tenofovir (Viread), lamivudine (Epivir), adefovir (Hepsera) and telbivudine (Tyzeka) — can help fight the virus and slow its ability to damage your liver.

What is the HBV?
Hepatitis B virus (HBV) is a virus that affects the liver. It is usually transmitted by injectable drug abuse, transfusion of infected blood, unhygienic tattooing practices, coming into contact with blood infected with HBV, or by unprotected sex. Acute HBV infection is the period that covers the period immediately after HBV infection. Most people are asymptomatic. About 5% to 40% of people with acute HBV develop symptoms such as jaundice (yellowish discolouration of the eyes and skin), tummy pain, tiredness, nausea, and vomiting. While most people clear the virus after acute HBV infection, the virus remains in others (chronic HBV infection) and causes major health problems (excessive tiredness and eventually may end with liver failure leading to vomiting blood, confusion, and death). Occasionally, people with acute HBV may develop immediate liver failure (fulminant HBV infection). The best way to treat acute HBV is not clear. We sought to resolve this issue by performing this review. We included all randomised clinical trials (RCTs) (clinical studies where people are randomly put into one of two or more treatment groups) published to August 2016. We included only trials in which participants with acute HBV infection had not undergone liver transplantation previously and did not have liver disease due to other viral infections. Apart from using standard Cochrane methods which allow comparison of only two treatments at a time (direct comparison), we planned to use an advanced method which allows comparison of the many different treatments individually which are compared in the trials (network meta-analysis). However, because of the nature of the information available, we could not determine whether the network meta-analysis results were reliable. So, we used standard Cochrane methodology.
