What is bird flu in humans and why should we be concerned?

 

The avian flu It is transmitted from animals and humans through saliva, mucous membranes, and their feces. This dangerous infection, which has its point of similarity with the pandemic from Coronavirus, it can occur when the virus enters through a person’s eyes, nose, or mouth. The virus is usually present in the air and is inhaled by a person when they touch something containing the virus and then touch a hole in the body.

According to experts, some human infections with some avian-influenced viruses have been recorded, most often after unprotected contact with infected birds or surfaces contaminated by avian flu.

In recent times, very few cases of the spread of bird flu from one person to another have been reported. Despite this, given the potential for avian flu to change and acquire the ability to easily infect people, monitoring human infections and person-to-person spread is vital to public health.

What are the symptoms of type A bird flu?

As a general rule, the symptoms of bird flu in humans can be divided into mild and severe and included cases of conjunctivitis, flu-like illnesses, which are often accompanied by abdominal pain, nausea, diarrhea, vomiting, severe respiratory diseases, changes neurological and compromise other organs.

Asian origin H7N9 viruses and HPAI Asian H5N1 viruses have been responsible for the majority of human cases infected with the virus to date worldwide, including most cases of severe illness and more. cases of death.

How is bird flu detected?

Avian influenza cannot be diagnosed solely by clinical signs and symptoms, but requires laboratory testing. This is usually diagnosed by taking a sample from the upper respiratory tract (nose or throat) of the affected person.

This test is then sent to the laboratory, where any of the avian influenza A viruses will be looked for through a molecular test. In critically ill patients, taking specimens and samples from the lower respiratory tract may lead to the diagnosis of influenza A infection. However, patients who are not very ill or have already recovered, can be difficult to reach. to detect the virus.

How is bird flu cured?

Experts recommend a neuraminidase inhibitor for the treatment of mild bird flu infections in humans. CDC released guidelines on avian influenza for healthcare professionals and laboratory personnel, including guidelines on the use of antiviral drugs to treat human infections with novel influenza viruses associated with other serious illnesses.

These analyzes of the virus have led to the conclusion that the virus is susceptible to oseltamivir, peramivir, and zanamivir. However, the antiviral resistance of the H5N1 and H7N9 viruses of Asian origin isolated from some cases in humans has been evidenced. Therefore, monitoring of antiviral resistance among avian influenza viruses is vital and continuous.
