Speaker Notes Hepatitis B is a serious liver infection caused by the hepatitis B virus (HBV). In today’s presentation, we will discuss the cause, transmission, symptoms, and prevention of Hepatitis B.

• Hepatitis B virus (HBV)
• Double-stranded DNA virus
• Hepadnavirus family
• Cannot replicate on its own

Speaker Notes Hepatitis B is caused by the hepatitis B virus (HBV). HBV is a small, double-stranded DNA virus belonging to the Hepadnavirus family. This virus is unique because unlike most DNA viruses, it cannot replicate on its own inside a host cell.

Transmission of Hepatitis B

• HBV is transmitted through contact with infected body fluids
• Blood
• Semen
• Vaginal fluids
• Saliva (in high concentrations)

Speaker Notes HBV is transmitted through contact with infected body fluids. The most common ways to get hepatitis B are:

• Contact with infected blood, such as from a needlestick injury or from sharing needles or syringes with someone who has hepatitis B
• Sexual contact with an infected person
• From an infected mother to her newborn baby during childbirth or shortly after birth

Slide 4

Populations at Risk

• Infants born to mothers with HBV
• People who have multiple sexual partners
• Men who have sex with men (MSM)
• People who inject drugs
• People who receive frequent blood products or blood transfusions
• Healthcare workers
• Travelers to areas with high HBV rates

Speaker Notes Certain populations are at higher risk of contracting Hepatitis B. These include:

• Infants born to mothers with HBV: Because of shared bodily fluids during childbirth or shortly after birth.
• People with multiple sexual partners: Increased risk of exposure to infected bodily fluids.
• Men who have sex with men (MSM): Higher risk of exposure during sexual contact.
• People who inject drugs: Sharing needles and syringes with infected individuals.
• People who receive frequent blood products or blood transfusions: Risk associated with blood products.
• Healthcare workers: Risk of needlestick injuries or exposure to infected body fluids.
• Travelers to areas with high HBV rates: Particularly if engaging in activities that could increase exposure to bodily fluids.

Slide 5

Signs and Symptoms

• Acute Hepatitis B:
  • May not experience any symptoms
  • Fatigue
  • Loss of appetite
  • Nausea and vomiting
  • Abdominal pain
  • Dark urine
  • Jaundice (yellowing of the skin and whites of the eyes)
• Chronic Hepatitis B:
  • Often no symptoms
  • May experience fatigue, weakness, or abdominal pain

Speaker Notes The signs and symptoms of Hepatitis B can vary depending on whether the infection is acute (short-term) or chronic (long-term).

• Acute Hepatitis B: Some people with acute hepatitis B may not experience any symptoms at all. However, some common symptoms include fatigue, loss of appetite, nausea and vomiting, abdominal pain, dark urine, and jaundice (yellowing of the skin and whites of the eyes). These symptoms typically appear within 1-6 months after exposure to the virus.
• Chronic Hepatitis B: Many people with chronic hepatitis B don’t have any symptoms. However, some people may experience fatigue, weakness, or abdominal pain. It’s important to note that chronic HBV infection can lead to serious liver damage, including cirrhosis (scarring of the liver) and liver cancer.

Diagnosis of Hepatitis B

• Blood tests
• HBsAg test: Detects the presence of the hepatitis B surface antigen, which indicates current
