China reveals world's first case of human infection with avian influenza N10N3

In early June 2021 China , he reported the world's first case of human infection with a strain of avian influenza H10N3. The National Commission health care China reported that the disease developed in a 41-year-old man from the eastern province of Jiangsu. The man was hospitalized in late April with a fever, but now his condition is stable enough to be discharged from the hospital.

Avian influenza is an infectious type of influenza that spreads to birds. There are many strains of avian influenza, and most of them are not dangerous for people, but in rare cases, people can also become infected with avian influenza. Strains dangerous to humans are not as easily transmitted from person to person as other respiratory infections. Usually, a person becomes infected when in close contact with an infected animal, alive or dead.

In China, the world's first case of human infection with avian influenza N10N3 has been identified

The virus spreads through body fluids such as faeces, saliva and nasal droplets. Thus, touching an infected bird, contacting its litter or litter, and preparing its meat for food can lead to human infection. The greatest risk of infection with avian influenza is noted in livestock markets. However, a person cannot contract avian influenza by eating well-cooked meat or eggs of an infected bird.

However, although the transmission of avian influenza from person to person is not too common, such cases occur. Like conventional influenza, this virus is transmitted by close personal contact through a suspension of drops in the air. The symptoms of avian influenza are similar to those of other types of influenza. They can include high fever or a feeling of heat, chills, muscle aches, headache and coughing. Symptoms can appear three to five days after infection.^[1]

In Russia, revealed the world's first infection of people with avian influenza H5N8

In Russia, the world's first infection of people with the H5N8 strain of avian influenza virus A. This was announced in February 2021 by the head of Rospotrebnadzor Anna Popova. According to her, the virus cannot yet be transmitted from person to person, but in the future this can happen due to its mutation.

The H5N8 virus was detected in seven employees of a poultry farm in southern Russia, where in December 2020 an outbreak of influenza was recorded among the number of birds. All sick employees, as Popova reported, suffered the disease well, the clinical picture of the course of the disease was very easy, while the researchers managed to record the response of the immune response to infection in all patients.

Since the virus is detected early, it gives time to prepare for its possible mutations when this flu may be able to be transmitted from person to person and prepare test systems and vaccine platforms, Popova said.

In the Russian Federation, the world's first infection of people with avian influenza H5N8 was revealed

Information on the transmission of the virus from birds to humans is sent to the World Health Organization. Scientists from the Vector Center have already placed data from full-genome sequencing of virus A (H5N8) in the international GISAID database with those mutations that allowed it to overcome the interspecific barrier.

Virologist Anatoly Altstein says that there is always a possibility of a new pandemic in the world due to possible mutations of the avian influenza virus. According to him, scientists already have the development of a vaccine for avian influenza, but it is too early to talk about creating a universal drug.

Anna Popova emphasized that the great task of science is to track the interspecific transition of the virus in time, as happened with the discovery in Russia of the world's first case of human infection with avian influenza.

We have examples of swine flu, avian flu, and in time to see the beginning of this interspecific transition is a big task of science. All previous cases, unfortunately, were recorded only when a person began to get sick and hurt seriously, "she said.[2]
