How does H5N1 influenza spread to people? Why is there so much concern about H5N1 influenza A törzs a HPAI A(H5N1) (az A az A típusra utal, HPAI rövidítés, angolul highly pathogenic avian influenza virus, azaz magas patogenitású madárinfluenza-vírus). A HPAI A(H5N1) sok madárpopulációban jelen van, különösen Délkelet-Ázsiában.

H5N1 is a type of influenza virus that causes a highly infectious, severe respiratory disease in birds called avian influenza (or bird flu). Human cases of H5N1 avian influenza occur occasionally, but it is difficult to transmit the infection from person to person. When people do become infected, the mortality rate is about 60% The H5N1 strain is a fast-mutating, highly pathogenic avian influenza virus (HPAI) found in multiple bird species. It is both epizootic (an epidemic in non-humans) and panzootic (a disease affecting animals of many species especially over a wide area) One virus that causes bird flu is called H5N1. The H5N1 virus can cause severe flu with a high mortality rate. However, according to the Centers for Disease Control and Prevention (CDC),.. Asian HPAI H5N1 viruses have infected the respiratory tract of humans, causing severe illness (e.g. pneumonia and respiratory failure) and death in some people. The majority of human infections with Asian HPAI H5N1 have occurred among children and adults younger than 40 years old As of writing, Chinese officials reported that there are no cases of the H5N1 in humans. The World Health Organization (WHO) states that the bird flu virus can spread to humans but in just rare cases
