It is less common in mammals and in humans. Avian Influenza was first diagnosed in birds in 1878 in Italy. But H5N1 was only isolated by scientists more than 100 years later, in 1996, in geese in Guangdong province, in southern China. Influenza viruses are divided into Low Pathogenicity (LPAI, mild) and High Pathogenicity (HPAI, severe): Low Pathogenicity: affects birds more mildly and often asymptomatically. The bird mortality rate in this case is low; High Pathogenicity: the disease manifests itself more severely, spreads rapidly among birds and has a high mortality rate among animals.
