Confinement: why schools, colleges and high schools will this time remain open

Reasons linked to school dropout and the economy explain this choice in particular.

Avian influenza , known informally as avian flu or bird flu, is a variety of influenza caused by viruses adapted to birds. The type with the greatest risk is highly pathogenic avian influenza (HPAI).

The avian influenza (AI) virus, which is the type A influenza virus adapted to an. avian host, has been an important pathogen for the poultry industry and a drop in egg production are also frequently observed. Although the LPAI virus. may cause mortality in the field, mortality is generally low and may

If avian flu has not yet returned in France, the risk of introducing this highly contagious and fatal virus in birds fell on Thursday from "moderate" to "high" in 46 French departments. So far, no proven case has been recorded in the national territory but "the disease was found in two swans in the Netherlands on October 23," read the statement from the Ministry of Agriculture. Domestic outbreaks have also been confirmed in the Netherlands, Germany and the United Kingdom.

Second federal state affected: swine fever also in Saxony

After Brandenburg, a case of African swine fever (ASF) has now also been detected in Saxony. © Sven Hoppe / dpa Piglets on the farm of a piglet farmer and pig fattening company in a stable. The animal disease, which is harmless to humans, has been confirmed in a wild boar shot in the district of Görlitz, as the Saxon Ministry of Social Affairs announced on Saturday.

chickens and ducks together, selling of live birds, and deficient disease surveillance. To prevent human infection with avian influenza (H5N1), knowledge of avian influenza epidemiology is needed. We therefore describe the epidemiology of HPAI outbreaks in chickens in Bangladesh.

Avian influenza virus H9N2 antibodies were detected in chicken sera from whom the virus were isolated . also anti H9N2 antibodies were diagnosed in serum samples collected from chicken flocks for both egg and meat production in different areas by using HI and ELISA tests and the percentage of

What is avian flu?

Also known as “avian influenza”, avian influenza is a highly contagious viral infection affecting wild or captive birds. Transmitted by the respiratory or digestive tracts, this disease, very pathogenic and potentially fatal for birds, is also transmitted very quickly. "It is a virus that must be taken very seriously," said Jean-Yves Ferré, member of the Cristal network of veterinarians, interviewed by Liberation. It only takes the droppings of a sick, wild animal to enter a farmed animal range for the animals to be contaminated. "

Illustration in 2006, when the Ministry of Agriculture confirmed the contagion of a farm of 11,000 turkeys in Ain, resulting in the death of 400 animals and the euthanasia of others. If the National Health Security Agency (ANSES) recalls that bird flu stem cells can infect "certain mammals and under certain conditions humans", Jean-Yves Ferré nevertheless wants to be reassuring: "On the last three episodes avian influenza in France, we have not observed any case of human contamination. ”

Containment: high schools, license examination centers ... These blockages that affect the country

In 2014, a sentinel chicken surveillance for avian influenza viruses was conducted in aquatic bird habitat near Wuxi City, Jiangsu Province, China. However, wild birds, such as tree sparrows, songbirds, parakeets, and finches, have also been implicated as a source of virus transmission

Avian , swine and other zoonotic influenza virus infections in humans may cause disease ranging from mild upper respiratory tract infection (fever and cough), early sputum production and rapid progression to severe pneumonia, sepsis with shock, acute respiratory distress syndrome and even death.

Which departments are concerned?

On its site, the ministry listed the 46 departments now placed in "high risk zone", including Gers and Landes, the main French producers. "The departments concerned are those which are located in wetlands where birds can land but also the departments which are located in the migration corridors", explains to Libé Eric Cachan, president of the National Union of Poultry Labels of France (Synalaf ). "We are entering a period of migration and the risk of contact between wild and captive birds is particularly high", adds Jean-Yves Ferré.

What are the measures implemented by the producers?

As of Friday, November 6, breeders located in the 46 departments concerned must therefore lock up poultry, or protect them from contact with the outside world by reducing the area of ​​the runs. "By increasing the density of birds per space, we help scare away migrating birds," adds Eric Cachan. Gatherings, competitions and other events are also prohibited throughout the country, as is the "release of game birds", one can read on the ministry's website.

How did the professionals in the sector react?

Drawing lessons from previous epidemics which caused the avian sector to lose tens of millions of euros in 2005, 2016 and 2017, producers now say they are "better prepared". "For the moment, we are calm, no case has been recorded in our territory, it is only a question of preventive measures", affirms Eric Cachan. "To have lived through previous crises, we did not want to have to manage a health crisis in addition to the consequences of confinement", declared for her part to AFP Marie-Pierre Pé, director of the interprofessions of the Interprofessional Committee of the palmipeds with liver bold (Cifog).
