What cause Avion Flu?

The avian flu, also known as bird flu, is caused by infection with avian influenza viruses. These viruses are found in wild birds and can spread to domestic poultry and occasionally to humans. The most common type of avian influenza virus that infects humans is the H5N1 strain.

The avian flu virus is spread through contact with infected birds, their saliva, nasal secretions, or feces. It can also be spread through contact with contaminated surfaces or objects. The virus can enter the body through the eyes, nose, or mouth.

The avian flu can cause a range of symptoms in humans, including:

* Fever

* Cough

* Sore throat

* Muscle aches

* Joint pain

* Fatigue

* Weakness

* Diarrhea

* Vomiting

* Conjunctivitis (pink eye)

In severe cases, the avian flu can lead to pneumonia, respiratory distress, and death.

The avian flu is a serious disease, but it is important to remember that the risk of infection is low for humans. Most cases of avian flu in humans have occurred in people who have had close contact with infected birds or their environment.

There is no specific treatment for the avian flu, but antiviral medications can help to reduce the symptoms and shorten the course of the disease.
