Italian public health authorities diagnosed H9N2 influenza virus infection using laboratory tests that detect the virus&#8217;s genetic material.<\/p>\n<p>What is H9N2 influenza virus?<\/p>\n<p>H9N2 influenza  <a href=\"https:\/\/www.sciencealert.com\/virus\" class=\"lar_link lar_link_outgoing\" data-linkid=\"73053\" data-postid=\"196615\" rel=\"nofollow noopener\" target=\"_self\">viruses<\/a> are influenza A viruses. This large group of viruses includes two of the viruses causing human seasonal influenza (H1N1 and H3N2) as well as many other viruses that infect birds.<\/p>\n<p>H9N2 influenza viruses are classified as &#8220;low pathogenicity avian influenza viruses&#8221;. &#8220;Low pathogenicity&#8221; refers to their ability to cause disease in poultry (avian influenza is a major threat to poultry farming), but it is unusual for H9N2 to cause anything other than mild illness in humans.<\/p>\n<p><img decoding=\"async\" src=\"https:\/\/www.newsbeep.com\/uk\/wp-content\/uploads\/2026\/04\/Chickens-outdoors-on-grass-642x361.jpg\" alt=\"a group of chickens outdoors\" width=\"642\" height=\"361\" class=\"wp-image-196647 size-medium\"   loading=\"lazy\"\/>Avian influenza is a major threat to poultry farming.

This case of H9N2 currently shows no signs of this.<\/p>\n<p>We know that this particular strain of influenza virus would need to acquire mutations in order to become <a href=\"https:\/\/www.bmj.com\/content\/392\/bmj.s605\" rel=\"nofollow noopener\" target=\"_blank\">well-adapted to growing in humans<\/a>.<\/p>\n<p>As a precaution, <a href=\"https:\/\/www.salute.gov.it\/new\/it\/comunicato-stampa\/virus-influenzale-h9n2-identificato-caso-lombardia-attivate-le-ordinarie\/\" rel=\"nofollow noopener\" target=\"_blank\">Italian public health authorities have traced contacts of the patient<\/a> to confirm there was no onward transmission.
