The death rate of this deadly flu may be as high as 8%, which has caused more than 100 seal pups in the Northeastern US waters to die from pneumonia, which may threaten human health. Scientists believe that this H3N8 (H means outer membrane hemagglutinin, N means neuraminidase) dog flu was mutated from horses 5 years ago and transmitted to dogs, which can attack human nasal proteins and human upper respiratory tract mucosa.
influenza A is a respiratory disease caused by myxoviruses and can be transmitted through the respiratory tract of many animals (dogs, chickens, ducks, etc.). Patients usually show symptoms of common flu, and in severe cases sometimes diarrhea and vomiting, pneumonia, respiratory failure and even death. The effective prevention method now is vaccination.
H3N2 influenza is a respiratory disease caused by the H3N2 influenza virus. It can spread through the respiratory tract. Patients usually show symptoms of common flu, but can also cause death. An effective precaution is vaccination.
H3N8 is a subtype of influenza A virus, which is believed to originate from the large-scale human flu of 1889 and 1990. This influenza virus was found in wild ducks in 1997 and was found in 2004. It is transmitted to dogs, and because dogs do not have the natural immunity to the virus, they can easily spread from dog to dog.
