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.

- 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

Hydropericardium hepatitis syndrome, Israel
An epidemic of fowl adenovirus serotype 4 (FAdV4), which causes hydropericardium hepatitis syndrome (HHS), is ongoing across Israeli poultry operations, with 48 confirmed farm-level outbreaks across multiple regions and cross-border detections in Palestine. The outbreak, initially driven by vertical transmission from a single infected breeder flock, has shifted to predominantly horizontal spread, complicating containment. Authorities have issued a mandatory nationwide vaccination order for all breeder flocks, but the extent of spread and the incomplete eradication of the source population raise concerns about prolonged transmission into subsequent production cycles.
