20 interesting facts about Hepatitis B

Hepatitis B is a viral infection that targets the liver and has the potential to cause both acute and chronic diseases. Globally, it’s a major health concern due to its widespread prevalence and potential severity. The virus is transmitted through contact with the blood or other body fluids of an infected person. Despite its potential severity, many individuals remain unaware of their infection status, underlining the importance of awareness, early detection, and preventive measures.

1. Hepatitis B is caused by the hepatitis B virus (HBV).
2. The World Health Organization (WHO) estimates that over 290 million people worldwide are living with chronic hepatitis B infection.
3. Hepatitis B is 50 to 100 times more infectious than HIV.
4. In many cases, hepatitis B can be asymptomatic, meaning people can have the virus and spread it without knowing they have it.
5. Symptoms, when they occur, can include jaundice, dark urine, fatigue, abdominal pain, and fever.
6. Chronic hepatitis B can lead to serious health issues such as cirrhosis or liver cancer.
7. Mother-to-child transmission during childbirth is a common route of infection in endemic areas.
8. Hepatitis B is preventable with a vaccine, which has been available since 1982.
9. The hepatitis B vaccine is over 95% effective in preventing infection and the development of chronic disease and liver cancer due to HBV.
10. There is no specific treatment for acute hepatitis B; care is aimed at managing symptoms and supporting the body’s immune response.
11. Antiviral medications can be used to treat chronic hepatitis B to slow the progression of the disease.
12. Using barrier methods during sexual activity, avoiding sharing needles, and using sterile equipment for tattoos and piercings can reduce the risk of HBV transmission.
13. The liver has the capacity to heal over time, but extensive or chronic damage can be irreparable.
14. Every year, hepatitis B results in an estimated 887,000 deaths, mainly from complications such as cirrhosis and liver cancer.
15. Many countries include the hepatitis B vaccine in routine infant immunisation programmes.
16. The risk of developing chronic disease depends on the age at which a person becomes infected; young children are at a higher risk.
17. Screening of pregnant women for HBV is crucial to prevent the transmission to their newborns.
18. Hepatitis B surface antigen (HBsAg) is a blood test to check for hepatitis B infection.
19. It can take 30 to 180 days for symptoms of hepatitis B to develop after someone is infected.
20. The use of safe and clean blood products can reduce the risk of HBV transmission.

Hepatitis B remains a significant global health threat, but advancements in medicine and increased public awareness have improved prevention and treatment options. Continued efforts to promote vaccination, safe practices, and early detection can further reduce the disease’s impact. As we navigate this challenge, we are reminded of the intricate balance between human health and infectious diseases.
