. Six countries are considered to be endemic for Asian HPAI H5N1 virus in poultry (Bangladesh, China, Egypt, India, Indonesia, and Vietnam) H5N1 is a type of influenza virus that causes a highly infectious, severe respiratory disease in birds called avian influenza (or bird flu) What is H5N1? 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. Egy Ázsiában megjelent törzs világszerte terjed , madarak tízmillióival végzett és százmillióik leöléséhez vezetett, hogy terjedését megfékezzék
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

Influenza Virus Vaccine, H5N1 is for use in adults and children who are at least 6 months old. Influenza Virus Vaccine, H5N1 works by exposing you to a small dose of the virus, which causes the body to develop immunity to the disease. This vaccine will not treat an active infection that has already developed in the body SUMMARY Pandemic influenza virus has its origins in avian influenza viruses. The highly pathogenic avian influenza virus subtype H5N1 is already panzootic in poultry, with attendant economic consequences. It continues to cross species barriers to infect humans and other mammals, often with fatal outcomes. Therefore, H5N1 virus has rightly received attention as a potential pandemic threat L'epidemia da virus H5N1, iniziata alla fine del 2003 nel sud-est asiatico, ha coinvolto sinora più di 150 milioni di volatili. Oltre che in Vietnam , Thailandia , Cambogia , Laos , Indonesia , la malattia è stata individuata in Corea , Giappone , Cina , Russia , Kazakistan , Mongolia HPAI H5N1 is thus a poultry disease. Currently, it remains extremely difficult for HPAI viruses to infect people, but there is a serious concern the virus may evolve to allow rapid human to human transmission and mortality. Wild birds can also be infected with, and killed by, HPAI viruses but in population terms this is rare Other articles where H5N1 virus is discussed: influenza: Pandemics and epidemics: This same virus, H5N1, reappeared among chicken flocks in Southeast Asia during the winter of 2003-04, again infecting some people fatally, and it has reappeared periodically since, primarily in wild birds, domestic poultry, and humans.

H5N1 virus was first detected in China in 1996 where it caused the death of a number of geese. After undergoing reassortment to obtain new genes, it surfaced in Hong Kong in 1997 where it became widespread in live poultry markets
The transmission of H5N1 virus to humans is by direct contact with infected birds and poultry, close contact with their secretions or contaminated fomites. There is no evidence that people have been infected with bird flu by eating safely handled and properly cooked poultry. After a mean incubation period of 2-5 days, infection onsets with high. Influenza A(H5N1) virus can be cultured using cell lines (Madin-Darby canine kidney cells and LLCMK2 cells) that are routinely used for the detection of influenza viruses.

About 50 percent of the infected models became ataxic, bradykinetic and had postural abnormalities ABSTRACT. Avian influenza virus (H5N1) emerged in Hong Kong in 1997, causing severe human disease. In recent years, several outbreaks have been reported in different parts of Asia, Europe and Africa, raising concerns of dissemination of a new and highly lethal influenza pandemic That was certainly the case in late 1997, just after China's assumed sovereignty over Hong Kong, when the territory was hit by an outbreak of the H5N1 virus known as bird flu Avian flu (sometimes called bird flu) is a respiratory disease that usually infects birds, not people. There are different types of avian flu, such as H5N1 and H7N9. People rarely get bird flu, but when they do it usually happens after contact with infected birds (such as chickens, turkeys, geese, pigeons, and pheasants) A highly pathogenic avian influenza A (H5N1) virus has crossed the species barrier to cause deaths in humans in Asia and poses an increasing threat of a pandemic.
