when do hepatitis b symptoms occur?

Symptoms. Signs and symptoms of hepatitis B range from mild to severe. They usually appear about one to four months after you've been infected, although you could see them as early as two weeks post-infection. Some people, usually young children, may not have any symptoms.

These signs and symptoms last for two to 12 weeks. Most acute hepatitis C infections today occur in people who share needles to inject drugs.

Studies published in the last several years have found that transient HBsAg-positivity can be detected for up to 18 days after vaccination (up to 52 days among hemodialysis patients). This does not mean the person is infected with HBV.
1060565
Additional signs and symptoms include splenomegaly, hepatomegaly, lymphocytosis, and liver dysfunction. Fever and lymphadenopathy usually resolve within 2 weeks after onset but can persist for a month, or in rare cases even longer.

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.
874404
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.

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.

Symptoms. The incubation period of hepatitis A is usually 14–28 days. Symptoms of hepatitis A range from mild to severe, and can include fever, malaise, loss of appetite, diarrhea, nausea, abdominal discomfort, dark-coloured urine and jaundice (a yellowing of the skin and whites of the eyes).
877617
Your risk of hepatitis B infection increases if you: Have unprotected sex with multiple sex partners or with someone who's infected with HBV. Share needles during IV drug use. Are a man who has sex with other men.

When signs and symptoms are present, they may include jaundice, along with fatigue, nausea, fever and muscle aches. Acute symptoms appear one to three months after exposure to the virus and last two weeks to three months. Acute hepatitis C infection doesn't always become chronic.

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.

There's no cure for hepatitis B, but there are several treatments that can help with managing symptoms and reducing the risk of long-term health problems, such as cirrhosis. If you have hepatitis B, try to get in for a blood test every six months or so to monitor your viral load and liver health.

Once you are diagnosed with chronic hepatitis B, the virus will most likely stay in your blood and liver for a lifetime. It is important to know that you can pass the virus along to others, even if you don't feel sick.

Hepatitis B Symptoms in Infants and Children The hepatitis B virus mainly affects the liver, and enters the liver cells (called hepatocytes) when in the body. Reproduction of the virus causes death of these cells. The sudden death of a large number of liver cells can cause liver damage or even liver failure.
704019
Most people with chronic hepatitis C virus infection do not have any symptoms or have general, or common symptoms such as chronic fatigue and depression. Many people eventually develop chronic liver disease, which can range from mild to severe, including cirrhosis (scarring of the liver) and liver cancer.

How long after exposure to HBV can HBsAg be detected in an infected patient's blood? HBsAg will be detected in an infected person's blood an average of 4 weeks (range: 1–9 weeks) after exposure to the virus.

There's no cure for hepatitis B. The good news is it usually goes away by itself in 4 to 8 weeks. More than 9 out of 10 adults who get hepatitis B totally recover. However, about 1 in 20 people who get hepatitis B as adults become “carriers,” which means they have a chronic (long-lasting) hepatitis B infection.
