Hepatitis B: Causes, Symptoms, Diagnosis and Treatment

Hepatitis-B

According to the World Health Organization hepatitis B is a serious liver infection caused by a virus called Hepatitis B. So it’s a big health issue worldwide affecting millions of people. In this article we’ll talk about what causes its symptoms and how to prevent it.

What is Hepatitis B?

Hepatitis B is caused by a virus that spreads through contact with an infected person’s blood or other body fluids. It can make the liver inflamed leading to short term (acute) or long term (chronic) problems. Chronic cases can be risky, potentially causing liver cirrhosis or cancer. Hepatitis B is a viral infection that attacks the liver and can cause both acute and chronic disease. The virus is most commonly transmitted from mother to child during birth and delivery in early childhood as well as through contact with blood or other body fluids during sex with an infected partner, unsafe injections or exposures to sharp instruments. The World Health Organization estimated that 296 million people were living with chronic hepatitis B infection in 2019 with 1.5 million new infections each year. In 2019 hepatitis B resulted in an estimated 820,000 deaths mostly from cirrhosis and hepatocellular carcinoma (primary liver cancer). Hepatitis B can be prevented by vaccines that are safe, available and effective.

What is Acute or Chronic Hepatitis B?

Hepatitis B infection may be short lived also called acute. Or it might last a long time also known as chronic.

Acute hepatitis B infection:

In less than six months your immune system likely can clear acute hepatitis B from your body and you should recover completely within a few months. Most people who get hepatitis B as adults have an acute infection but it can lead to chronic infection.

Chronic hepatitis B infection:

Last six months or longer. It lingers because your immune system can’t fight off the infection. Chronic hepatitis B infection may last a lifetime possibly leading to serious illnesses such as cirrhosis and liver cancer. Some people with chronic it may have no symptoms at all. Some may have ongoing fatigue and mild symptoms of acute hepatitis. The younger you are when you get it particularly newborns or children younger than 5 the higher your risk of the infection becoming chronic. The chronic infection may go undetected for decades until a person becomes seriously ill from liver disease.

What are the Symptoms of Hepatitis B?

Symptoms of acute hepatitis B range from mild to severe. They usually appear about 1 to 4 months after you’ve been infected, although you could see them as early as two weeks after you’re infected. Some people, usually young children, may not have any symptoms. It signs and symptoms may include:

  • Scarring of the liver (cirrhosis)
  • Liver cancer
  • Liver failure
  • Reactivation of the hepatitis B virus
  • Other conditions

What is the Prevention of Hepatitis B?

This vaccine is typically given as two injections separated by a month or three or four injections over six months depending on which vaccine is given. You can’t get hepatitis B from the vaccine. The hepatitis B vaccine is recommended by the United States Advisory Committee on immunization practices for adults 19 to 59 years of age who don’t have a contraindication to the vaccine.

  • Treatment can;
  • Slow the advance of cirrhosis
  • Reduce cases of liver cancer
  • Improve long term survival

Most people who start it treatment must continue it for life. It is estimated that 12-25% of people with chronic this infection will require treatment depending on setting and eligibility criteria. The ongoing 2023 update of the World Health Organization’s treatment guidelines will expand treatment eligibility and increase the proportion of people on treatment. In low income settings most people with liver cancer present late in the course of the disease and die within months of diagnosis. In high income countries patients present to hospital earlier in the course of the disease and have access to surgery and chemotherapy which can prolong life for several months to a few years. Liver transplantation is sometimes used in people with cirrhosis or liver cancer in technologically advanced countries with varying success.

What is Screening Healthy People for Hepatitis B?

  • Use illegal injected drugs
  • Are in prison
  • Were born in a country where it is common

HBV-HIV Coinfection:

About 1% or people living with HBV infection (2.7 million people) are also infected with HIV. Conversely the global prevalence of HBV infection in HIV infected persons is 7.4%. Since 2015 the World Health Organization has recommended treatment for everyone diagnosed with HIV infection regardless of the stage of disease. Tenofovir which is included in the treatment combinations recommended as first-line therapy for HIV infection is also active against HBV.
