how do you know if you have chronic or acute hepatitis b?

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.

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.

Hepatitis B is a liver infection caused by the hepatitis B virus. Some people with hepatitis B are sick for only a few weeks (known as “acute” infection), but for others, the disease progresses to a serious, lifelong illness known as chronic hepatitis B.

This test can detect the actual presence of the hepatitis B virus (called the “surface antigen”) in your blood. If a person tests “positive,” then further testing is needed to determine if this is a new “acute” infection or a “chronic” hepatitis B infection.

No. Hepatitis B is a sexually transmitted disease, but it is spread in other ways, too. This is a hardy virus that can exist on almost any surface for up to one month. You can get infected through contact with an infected person's blood or body fluids.

Hepatitis B is caused by the hepatitis B virus, which is spread in the blood of an infected person. It's a common infection worldwide and is usually spread from infected pregnant women to their babies, or from child-to-child contact.

Acute hepatitis C occurs within the first 6 months after someone is exposed to the hepatitis C virus. Hepatitis C can be a short-term illness, but for most people, acute infection leads to chronic infection. Chronic hepatitis C can be a lifelong infection with the hepatitis C virus if left untreated.

Blood tests can detect signs of the hepatitis B virus in your body and tell your doctor whether it's acute or chronic. A simple blood test can also determine if you're immune to the condition. Liver ultrasound. A special ultrasound called transient elastography can show the amount of liver damage.

Unlike hepatitis B and C, hepatitis A does not cause chronic liver disease and is rarely fatal, but it can cause debilitating symptoms and fulminant hepatitis (acute liver failure), which is often fatal.

But when they happen, the symptoms of types A, B, and C may include fatigue, nausea, poor appetite, belly pain, a mild fever, or yellow skin or eyes (jaundice). When hepatitis B and C become chronic, they may cause no symptoms for years.

Acute hepatitis B disease High levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST), within a range of 1000-2000 IU/mL, is the hallmark of this stage of HBV disease, although values 100 times above the upper limit of normal (ULN) can be also be identified.

Serum levels of both HBeAg and HBsAg rise rapidly during the period of viral replication. The presence of HBeAg in serum correlates with hepatitis B virus (HBV) infectivity, the number of infectious virions, and the presence of HBV core antigen in the infected hepatocytes.

Hepatitis is a virus that causes liver inflammation. 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.

Viral infections of the liver that are classified as hepatitis include hepatitis A, B, C, D, and E. A different virus is responsible for each type of virally transmitted hepatitis. Hepatitis A is always an acute, short-term disease, while hepatitis B, C, and D are most likely to become ongoing and chronic.

Inflammation that is sudden is known as acute hepatitis whereas inflammation that lasts longer than six months is known as chronic hepatitis. The hepatitis B virus attacks the liver cells causing them to swell and over time this leads to the development of scar tissue.

VIRAL HEPATITIS 22,23 Hepatitis C can cause transient elevations in liver enzymes (typically ALT), and physicians should consider testing even if repeat liver enzyme testing is normal.

How soon after exposure to the hepatitis B virus will symptoms appear, and how long do they last? If symptoms occur, they begin an average of 90 days (or 3 months) after exposure to the virus, but they can appear any time between 8 weeks and 5 months after exposure.
