The bird flu virus, avian influenza A, is divided into two main categories: Highly pathogenic avian influenza (HPAI) causes more serious illness in chickens and is more likely to kill them. Low pathogenicity avian influenza (LPAI) causes less serious illness in chickens and is less likely to cause death.

Most of the people who get bird flu have had close contact with infected birds or with surfaces that have been contaminated by the birds’ saliva, mucous, or droppings. It is also possible to get it by breathing in droplets or dust that contain the virus.

What was the bird flu pandemic?

The first outbreak of human infection by avian influenza viruses (H5N1) was observed in 1997 in Hong Kong. Since then a large number of outbreaks have been reported in different parts of the world. In fact, the spread of avian influenza H5N1 in various species including humans has lead to a current pandemic threat.

Is bird flu curable in humans?

Studies suggest that antiviral drugs developed for human flu viruses would work against bird flu infection in humans. The H5N1 virus, however, appears to be resistant to at least two of the drugs, amantadine and rimantadine.

Is bird flu A virus?

Avian influenza refers to the disease caused by infection with avian (bird) influenza (flu) Type A viruses. These viruses occur naturally among wild aquatic birds worldwide and can infect domestic poultry and other bird and animal species. Avian flu viruses do not normally infect humans.

When did bird flu end?

The virus continued to kill chickens and to occasionally infect and sometimes kill people. But as the years passed, the number of human H5N1 cases subsided. There has not been a single H5N1 human infection detected since February 2017. This is the good news.

Is H1N1 a bird flu?

In the spring of 2009, scientists recognized a particular strain of flu virus known as H1N1. This virus is a combination of viruses from pigs, birds and humans that causes disease in humans. During the 2009-10 flu season, H1N1 caused the respiratory infection in humans that was commonly referred to as swine flu.

What happens if we get bird flu?

Bird flu symptoms in humans can vary and range from “typical” flu symptoms (fever, sore throat, muscle pain) to eye infections and pneumonia. The disease caused by the H5N1 virus is a particularly severe form of pneumonia that leads to viral pneumonia and multiorgan failure in many people who become infected.

What was FLU 1957?

In February 1957, a new influenza A (H2N2) virus emerged in East Asia, triggering a pandemic (“Asian Flu”). This H2N2 virus was comprised of three different genes from an H2N2 virus that originated from an avian influenza A virus, including the H2 hemagglutinin and the N2 neuraminidase genes.

Which flu is worse A or B?

Type A influenza is generally considered worse than type B influenza. This is because the symptoms are often more severe in type A influenza than in type B influenza. Type A influenza is more common than type B influenza.

Are Spanish flu and swine flu the same thing?

When humans became infected with the 1918 pandemic flu, which was originally a bird flu, we also passed it on to pigs. “One branch of the 1918 flu permanently adapted to pigs and became swine influenza that was seen in pigs in the US every year after 1918 and spread around the world,” says Taubenberger.

Does egg contain bird flu?

Although sick birds will normally stop producing eggs, eggs laid in the early phase of the disease could contain the virus in the egg-white and yolk as well as on the surface of the shell. Proper cooking inactivates the virus present inside the meat and eggs, the FSSAI said.

Where did Ebola come from?

Ebola virus disease ( EVD ) is a severe disease caused by Ebola virus, a member of the filovirus family, which occurs in humans and other primates. The disease emerged in 1976 in almost simultaneous outbreaks in the Democratic Republic of the Congo ( DRC ) and Sudan (now South Sudan).

How is bird flu prevented?

Avoid close contact with infected or suspected birds and animals, specially their droppings, saliva and other secretions. Avoid consuming raw / uncooked / partially cooked poultry products such as chickens and eggs. Cooking (half an hour & 700C) kills the bird flu virus. It makes food safe.

The designation “H1N1” indicates unique traits, which exhibit characteristics that identify the virus to the immune system and allows for attachment and replication of the virus. The “H” (hemagglutinin) and the “N” (neuraminidases) are both proteins that are found on the outer shell or envelope of the virus.
