HSN1 - a type of bird flu

H5N1 is a type of avian influenza (bird flu), which] to [mutated through antigenic drift into dozens of highly pathogenic varieties, but all current Z genotype H5N1 avian influenza virus. Genotype Z emerged through selection in 2002 from the previous Highly pathogenic H5N1 genotypes [2], which first appeared in China in 1996 and in birds in Hong Kong in 1997 in humans [3]. The "H5N1 viruses from human infections and closely relatedavian influenza virus isolated in 2004 and 2005 are a single genotype, often referred to as genotype Z. [1]

The subtypes of avian influenza have been confirmed in humans, ordered by the number of human deaths have been identified: H1N1 caused Spanish flu, H2N2 caused Asian Flu, H3N2 has caused the Hong Kong Flu, H5N1, H7N7, H9N2, H7N2, H7N3, H10N7.

All avian influenza (AI) viruses are Type A influenza virus of the family Orthomyxoviridae and all known strains of influenza AViruses infect birds. Influenza virus type A HA is divided into subtypes based on the (H) and neuraminidase (N) protein spikes of the virus core. There are 16 H types, each with up to 9 N subtypes, resulting in a potential of 144 different combinations of H and N.

Avian influenza (flu known as avian influenza, avian influenza A, influenza, influenza type A, or genus A flu) is an influence from one type of influenza virus is birds but can infect otherMammalian species.

A flu pandemic is an epidemic of influenza virus on a large scale, as the Spanish flu of 1918. The World Health Organisation (WHO) warns that there is considerable risk of an influenza pandemic within the next few years . One of the strongest candidates is the A (H5N1) subtype of avian influenza.

Myxovirus influenza A viruses usually antigenically variable influenza virus type A and influenza type C, which causesvarious respiratory diseases in humans.

Myxovirus influenza A viruses usually antigenically variable influenza virus type B and type C influenza virus that causes acute respiratory disease in persons

Influenza caused by infection with a strain of influenza virus type C

People should have the vaccination:

People 65 years or more.
Resident of nursing home and other chronic-care facilities.
Adults and adolescentschronic pulmonary or cardiovascular diseases, including asthma.
Health workers, nurses and others who may transmit the infection, the virus people at high risk of complications.

The people, the drugs are less able to fight infections because of an illness are born with it an infection with human immunodeficiency virus (HIV), the long-term treatment with steroids and / or treatment of cancer with X-rays or drugs.

Adultand young people, regular medical follow-up or hospitalization during the previous year due to chronic diseases (eg diabetes mellitus), kidney and blood diseases like sickle cell anemia.

Women who are in second or third trimester during flu season (December to March).
