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.

Although those with chronic hepatitis B infection live with an increased risk of developing liver disease later in life, many should expect to live long and healthy lives. Someone with chronic hepatitis B should be seen by a liver specialist every six months, or more often as needed.

A minority of people may develop severe symptoms during acute hepatitis B infection, and in rare cases it can lead to death. After the acute stage (more than six months after infection), many people with chronic hepatitis B have few or no symptoms.

Acute pancreatitis has a sudden onset and short duration, whereas chronic pancreatitis develops gradually and worsens over time, resulting in permanent organ damage.

Symptoms of chronic Hepatitis B can take up to 30 years to develop. Damage to the liver can silently occur during this time. When symptoms do appear, they often are a sign of advanced liver disease. Symptoms for both acute and chronic Hepatitis B can include fever, fatigue, abdominal pain, and jaundice.

All types of hepatitis are treatable but only A and C are curable. Most people with hepatitis A or hepatitis B infection will recover on their own, with no lasting liver damage. In rare cases, people with hepatitis B will develop chronic liver disease, including cirrhosis, liver failure, or liver cancer.

On average, symptoms appear 90 days (or 3 months) after exposure, but they can appear any time between 6 weeks and 6 months after exposure. How long do acute hepatitis B symptoms last? Symptoms usually last only a few weeks, but they can continue for up to 6 months.

Generally, the terms "acute" and "chronic" are used to delineate between effects on the basis of severity or duration. "Acute" effects usually occur rapidly as a result of short-term exposures, and are of short duration. "Chronic" effects generally occur as a result of long-term exposure, and are of long duration.

Acute hepatitis C is a contagious viral infection spread through contact with blood and bodily fluids that contain HCV. The main risk of the acute form of the disease is development into chronic hepatitis C, a more serious form of the disease that can cause liver damage and liver cancer.

How long do acute hepatitis B symptoms last? If symptoms occur, they usually last several weeks, but some people can be ill for as long as 6 months.

Viral hepatitis is an infection that affects the liver. There are at least six different types of hepatitis (A-G), with the three most common types being hepatitis A, hepatitis B and hepatitis C. Hepatitis A is an acute infection and people usually improve without treatment.
1182784
Most people with hepatitis A and B infections have mild or no symptoms. For people who get symptoms, flu-like warning symptoms (called a prodrome) often appear about 3 to 10 days before liver symptoms arrive. Symptoms include low-grade fever, muscle aches, loss of appetite, nausea, vomiting, and fatigue.

Hepatitis A vs. Hepatitis B. While hepatitis A and B both impact the liver, the two viruses differ greatly from one another. Hepatitis B is a blood-borne pathogen; its primary mode of transmission is through direct blood-to-blood contact with an infected person.

HBsAg (Hepatitis B surface antigen) - A "positive" or "reactive" HBsAg test result means that the person is infected with hepatitis B. This test can detect the actual presence of the hepatitis B virus (called the “surface antigen”) in your blood.

Hepatitis B and hepatitis C can also begin as short-term infections but in some people, the virus remains in the body, and causes chronic (lifelong) infection. There are vaccines to prevent hepatitis A and hepatitis B; however, there is no vaccine for hepatitis C.

Different strains of hepatitis exist, including hepatitis A, B, C, and D. The most common types of hepatitis are A, B, and C. Hepatitis A is usually a short-term infection while hepatitis B and C can cause long-term, or chronic, infections. A person can have both hepatitis B and hepatitis C at the same time.
