Bird Flu In India 2021: Here’s Everything You Need To Know About

Bird Flu

What Is Bird Flu?

Bird flu is an infectious viral disease that is caused by the Influenza Type A virus. The virus is found usually in poultry birds like chicken or turkeys.

In bird flu, various strains of Influenza Virus affect birds but the flu virus in animals can possibly change and infect humans easily.

General precautions are recommended to avoid the spread of the disease in humans.

Where Is It Originated From?

The first Avian influenza or bird flu was detected in 1996 in geese, in China, and was detected for the first time in humans in 1997 when an outbreak took place in poultry in Hong Kong.

Since then, the pathogenic Avian influenza virus is detected in more than 50 countries in wild birds as well as poultry in Asia, Africa, Europe, and the Middle East.

Canada reported the first human infection with the Asian H5N1 virus in 2014  and was an “imported” case because the traveler recently returned from China.

It is believed that an illegal bird trade or movement of infected poultry or migratory birds can be the reason for the cause of the spread.

The virus was contained after 1997 but re-emerged in various parts of the world recently. The epicenter turned out to be South East Asia and mammals like cats and lions were seem to be infected.

How Does It Spread? How Does It Mutate?

The Deadly virus does not easily infect humans but it’s a close contactor, prolonged contact with infected, sick, or dead birds might result in the infection in humans with the Asian H5N1 virus.

Aquatic Birds like ducks and geese act as a reservoir for the Influenza A virus and are the lead players when it comes to spreading the virus.

Most of the birds may be asymptomatic but spread the symptoms to others.

The birds have the ability to excrete while flying so it is possible that they may spread it anywhere in the world wherever they go. Water Birds who travel or migrate long distances drop the Influenza A virus and it might take place in poultry or terrestrial bird.

In some cases, the virus was seen infecting mammals like cats, dogs, pigs, and horses.

The strains of the virus cause low egg production and various other lenient symptoms in poultry birds but some symptoms might be severe and fatal.

Bird Flu Symptoms And Infecting Regions

Bird flu affects the gut in birds and the respiratory tract in humans.

This might result in lethal respiratory problems like pneumonia or ARDS, Acute Respiratory Distress Syndrome.

Symptoms of bird flu include abdominal pain, diarrhea, sore throat, fever, and cough. According to the Union Health Ministry, the antiviral drug “oseltamivir” is active in fighting against the virus in humans.

Precautionary measures like using PPEs and following hand hygiene in poultry farms are advised by the Ministry.

Is It Deadly?

Although the virus does not easily spread to humans, the close contact with an infected alive or dead bird might increase the chances of the infection in humans.

According to WHO, it is probably not possible for the disease to spread to humans if they have properly prepared and cooked the poultry food.

Since Influenza Type A virus is very sensitive to heat, it dies at extreme temperatures like cooking temperatures.

There is no current evidence that the disease cannot spread to people through properly cooked food but precautions are necessary to be taken.

6 out of 10 confirmed human cases of the H5N1 bird flu have resulted in death since the virus mutates and can be easily transferred from human to human.

The virus has the potential ability to cause a pandemic because it can alter its shape and attack the human cells if transferred from a human to another human.
