What are the different types of hepatitis?

Hepatitis A: Acute, spreads through contaminated food/water, vaccine available. Hepatitis B: Can be acute or chronic, spreads through blood/sex, vaccine available. Hepatitis C: Usually chronic, spreads through blood, curable with antivirals. Hepatitis D: Only infects those with Hepatitis B. Hepatitis E: Acute, waterborne, usually self-limiting.

Can hepatitis be cured?

Depends on type. Hepatitis A and E: No specific treatment needed; body clears infection. Hepatitis B: No cure but manageable with antivirals; some cases resolve spontaneously. Hepatitis C: CURABLE with 8-12 weeks of direct-acting antiviral pills (cure rate >95%). Early detection through screening is key.

Who should get tested for hepatitis?

CDC recommends: All adults get tested for Hepatitis C at least once. Hepatitis B screening for those born in high-prevalence countries, people with HIV, injection drug users, men who have sex with men, pregnant women, and those with elevated liver enzymes or risk factors.

How do I know if I have hepatitis?

Many people have no symptoms, especially early on. When symptoms occur: fatigue, nausea, loss of appetite, abdominal pain, dark urine, clay-colored stool, joint pain, jaundice (yellowing of skin/eyes). Chronic hepatitis can be asymptomatic for years while causing liver damage. Screening is essential.

Can I get vaccinated against hepatitis?

Hepatitis A vaccine: 2-dose series, recommended for all children and at-risk adults. Hepatitis B vaccine: 2-3 dose series, recommended for all children and unvaccinated adults. Combined Hepatitis A+B vaccine available. No vaccines exist for Hepatitis C, D, or E (Hepatitis E vaccine available in China only).

How is hepatitis transmitted?

Hepatitis A & E: Fecal-oral route (contaminated food/water). Hepatitis B: Blood, semen, vaginal fluids (sex, needles, mother-to-child). Hepatitis C: Primarily blood-to-blood (sharing needles, contaminated medical equipment, rarely sexual). Hepatitis D: Same as B (requires Hepatitis B co-infection).
