IBR and IPV in cattle

Updated 08.01.2024

Norway is regarded as free from infectious bovine rhinotracheitis and infectious pustular vulvovaginitis.

The aim of the surveillance programme for infectious bovine rhinotracheitis (IBR) and infectious pustular vulvovaginitis (IPV) is to document freedom from the infection in Norway according to the demands in ESA Decision 74/94/COL, and to contribute to the maintenance of this favourable situation.

Background

Infectious bovine rhinotracheitis and infectious pustular vulvovaginitis is a disease caused by bovine herpesvirus 1 (BHV-1). The virus affects the upper respiratory tract of cattle causing purulent nasal discharge, hyperaemia of the muzzle and conjunctivitis. Signs of general illness are fever, depression, reduced appetite, abortions and reduced milk yield. The virus may also infect the genital tract and cause pustular vulvovaginitis and balanoposthitis. IBR/IPV is classified as a list B disease in Norway and is notifiable to the Office International des Epizooties.

Norway has not experienced clinical outbreaks of infectious pustular vulvovaginitis since the early 1960s, when two outbreaks were diagnosed in cattle. In 1993, animals in one single herd were found seropositive after primary testing of bulk milk samples. All animals on the farm were slaughtered. Contact herds, dairy herds in the same region and red deer that were shot the same year were found seronegative. Later, BHV-1 infection has not been demonstrated in Norway.

EFTA Surveillance Authority (ESA) has recognised Norway as free from IBR since 1994. Decisions concerning the additional guarantees relating to IBR/IPV for bovines destined for Norway are described in ESA Decision 74/94/COL. Maintenance of the ESA Decisions accepting the IBR-free status of Norway requires annual reports of the surveillance of the disease.

2022

All samples tested in 2022 were negative for antibodies against bovine herpes virus (BHV-1).
