What is Hepatitis?

Viral hepatitis affects hundreds of millions worldwide. Hepatitis A and E spread through contaminated food/water (vaccine available for A). Hepatitis B and C spread through blood/bodily fluids; B has a vaccine, C is curable with antivirals. Chronic hepatitis B and C can silently damage the liver for decades before symptoms appear, making screening crucial.

Symptoms

  • Fatigue and weakness
  • Loss of appetite and nausea
  • Abdominal pain (right upper quadrant)
  • Dark urine
  • Clay-colored stool
  • Jaundice (yellowing of skin and eyes)
  • Joint pain
  • Fever (in acute cases)

Transmission

Varies by type. A & E: contaminated food/water. B: blood, sexual contact, mother-to-child. C: blood-to-blood (needles). D: requires HepB co-infection

Contagious Period: Varies by type; Hepatitis A: 2 weeks before through 1 week after jaundice appears; Hepatitis B & C: while virus is detectable in blood

Prevention

  • Hepatitis A and B vaccines
  • Safe food and water practices (especially when traveling)
  • Never share needles, razors, or toothbrushes
  • Practice safe sex (condoms)
  • Screen blood products
  • Universal precautions in healthcare settings
  • Hepatitis B vaccination for newborns
  • Screening and treatment programs

Initiatives including A&E blood tests, GP registration testing and free at-home tests have helped to find people who were previously undiagnosed, says NHS England.

Hepatitis C is spread through contact with blood infected with the virus, such as by sharing needles with someone who has it.

Donor blood is already screened for it.

It is a silent disease, meaning people often have no symptoms until much later.

Untreated, it can cause serious and potentially life-threatening liver damage.
