Which of the following is true regarding hbv – Delving into the intricacies of hepatitis B virus (HBV), this comprehensive exploration unravels the multifaceted nature of this infection, encompassing its transmission, symptoms, diagnosis, treatment, and preventive measures.
HBV, a prevalent liver infection, poses significant health concerns worldwide. Understanding its diverse aspects is paramount for effective management and prevention strategies.
HBV Transmission
Hepatitis B virus (HBV) is primarily transmitted through contact with infected blood or bodily fluids. The virus can be present in saliva, semen, vaginal fluids, and breast milk.
Risk factors for HBV transmission include:
- Unprotected sexual contact with an infected person
- Sharing needles or other drug paraphernalia
- Occupational exposure to infected blood or bodily fluids
- Contact with contaminated blood products
- Mother-to-child transmission during childbirth
HBV Symptoms
Symptoms of HBV infection can vary depending on the stage of the infection. In the acute phase, symptoms may include:
- Nausea and vomiting
- Abdominal pain
- Dark urine
- Fatigue
- Jaundice
In the chronic phase, symptoms may be less severe or absent. However, chronic HBV infection can lead to serious complications, such as:
- Cirrhosis
- Liver failure
- Liver cancer
HBV Diagnosis
HBV infection is diagnosed through blood tests that detect the presence of viral antigens and antibodies. Serological markers used in HBV diagnosis include:
- Hepatitis B surface antigen (HBsAg)
- Hepatitis B core antigen (HBcAg)
- Hepatitis B e antigen (HBeAg)
- Anti-HBs antibody
- Anti-HBc antibody
- Anti-HBe antibody
Early diagnosis is crucial for effective treatment and to prevent the development of complications.
HBV Treatment
Treatment for HBV infection typically involves antiviral medications, such as:
- Tenofovir
- Entecavir
- Lamivudine
- Adefovir
Antiviral medications can suppress viral replication and improve liver function. Adherence to treatment regimens is essential to achieve optimal outcomes.
HBV Prevention
HBV vaccination is highly effective in preventing infection. The vaccine is recommended for all infants, children, and adults who are at risk of exposure to the virus.
Other preventive measures include:
- Using condoms during sexual activity
- Avoiding sharing needles or other drug paraphernalia
- Practicing safe injection techniques in healthcare settings
- Proper handling and disposal of blood and bodily fluids
