There are four types of influenza (flu) viruses: A, B, C and D. Wild aquatic birds, including gulls, terns, and shorebirds, and wild waterfowl, such as ducks, geese and swans are considered reservoirs (hosts) for avian influenza A viruses.

Avian influenza A viruses are classified into the following two categories: low pathogenicity avian influenza (LPAI) A viruses, and highly pathogenic avian influenza (HPAI) A viruses. Highly pathogenic avian influenza viruses cause severe disease and high mortality in infected poultry. Only some avian influenza A(H5) and A(H7) viruses are classified as HPAI A viruses, while most A(H5) and A(H7) viruses circulating among birds are LPAI A viruses. HPAI A(H5) or A(H7) virus infections can cause disease that affects multiple internal organs with mortality up to 90% to 100% in chickens, often within 48 hours. Both HPAI and LPAI viruses can spread rapidly through poultry flocks. Avian influenza A viruses rarely infect people. The most frequently identified subtypes of avian influenza A viruses that have caused human infections are H5, H7 and H9 viruses.

The BioPerfectus Avian Influenza Virus (H5/H7/H9) Real Time PCR Kit is an in vitro diagnostic test, based on real-time PCR technology, for the detection and differentiation of RNA from the Avian Influenza Virus (AIV) H5, H7 and H9. Specimens can be obtained from human nasopharyngeal swabs and oropharyngeal swabs.

• No cross-reaction with other similar symptom viruses
• Internal control ensures that the whole process reliably
• Suitable for more mainstream instrument
