| Description |
There are three types of Duck Virus Hepatitis (DHV), which can cause a highly lethal, acute, contagious illness in ducklings, typically under six weeks of age. DHV type 1 is the most common cause of Duck Hepatitis A virus genotypes 1,2 or 3 (DHAV -1, -2, -3). In contrast, DHV type 2 is caused by Duck Adenovirus type 1 (DAstV-1), and DHV type 3 is caused by Duck Adenovirus type 2 (DAstV-2). Vaccines are available for DHAV-1 and DAstV-2. DVH is not considered zoonotic. |
