BACKGROUND INFORMATION
There are many strains of the avian influenza (AI) virus that can cause varying amounts of clinical illness in poultry. AI viruses can be classified into low pathogenic (LPAI) and highly pathogenic (HPAI) forms based on the severity of the illness they cause. Most AI virus strains are LPAI and typically cause little or no clinical signs in infected birds. However, some LPAI virus strains are capable of mutating under field conditions into HPAI viruses. HPAI is an extremely infectious and fatal form of the disease. The U.S. has had periodic outbreaks of LPAI in a number of states, but has not had an outbreak of HPAI in several years. Poultry producers in the U.S., including Minnesota, routinely monitor for AI.
