Mode of transmission of IBR virus is Venereal and Inhalation.
The infectious bovine rhinotracheitis (IBR) virus belongs to the group of herpes viruses. It causes in cattle a severe disease predominantly in the upper respiratory tract.
IBR can be transmitted by direct routes (nasal and genital secretions) and by indirect routes (people and equipment). Once animals are infected the virus hides from the immune system in the nervous system meaning that it can never be removed from the body and thus the animal is infected for life.
