Viral Diseases:
This being a viral disease, producida por el virus Orthomyxoviridae, gender Influenzavirus A y B, which affects the respiratory, digestive and nervous system of a large number of birds.
Classical avian plague, now known as avian influenza, is a highly contagious viral disease that can affect the respiratory, digestive, and nervous systems of chickens and other birds.
Symptoms may vary depending on the virus strain and can include lethargy, difficulty breathing, diarrhea, a drop in egg production, and high mortality in the most severe cases.
Prevention involves strengthening biosecurity measures, avoiding contact with wild birds, and acting quickly at the first sign of any suspicion.
The EFSA has created an interactive map with up-to-date information on avian influenza cases in the EU; it allows users to check and see the extent of a disease’s spread and serves to raise awareness among poultry farmers, breeders, and hobbyists that the threat is real.
We have put all the means at our disposal to ensure the health of our poultry.
Three ways of reading gives us the map:
– Maps showing the locations of outbreaks in affected regions or countries vary depending on the classifications of the main bird categories.
– If we select, for example, “Poultry,” we will see some subcategories of poultry such as:
In the representation, it appears in the map window, which informs us of the subtype of avian influenza that have been marked previously in settings, as a (H5N8, H5N1, H5N5…), with color codes.
If you zoom in on the map, you can see the country, department, and region; when you click on a colored marker, the corresponding information will appear.
The map is updated by EFSA (European Food Safety Authority), established in 2002, as this interactive map is generated using data from international, national, and regional health authorities in the various EU countries.
Virus detection of the highly pathogenic avian influenza in Europe
It is convenient to follow the directions of the diagrams (in Spanish or English), for all viruses, explaining what steps we should take and how infected poultry could transmit avian influenza to humans.
It is unlikely that the people from infection with the avian influenza virus, but this can happen. People can become infected when sufficient avian influenza viruses enter their eyes, nose or mouth, or when inhaled.
This could happen when the virus is present in the air in droplets or perhaps in the dust), and people breathe it in, or when they touch something that containing the virus and then touch their mouth, eyes, or nose.
Most cases of infection of avian influenza in people have been having unprotected contact with infected birds or contaminated surfaces.
However, there are no reported cases of infection of avian influenza in humans to the proper handling of poultry meat or eating meat poultry or poultry products thoroughly cooked.
Cases of avian influenza in humans have ranged from mild to severe. Signs and symptoms of avian influenza infection in people may include fever (temperature of 37.8 °C, 100 °F, or higher) with a feeling of fever, cough, sore throat, runny or stuffy nose, muscle or body aches, fatigue, headaches, red eyes (or conjunctivitis), and difficulty breathing.
Other possible symptoms are diarrhea, nausea, and vomiting. As is the case with the influenza (flu) seasonal, some people have a high risk of illness severity if they contract an infection of avian influenza. Among these people include pregnant women, people who have weakened immune systems and those of 65 years or more.
Usually, the cases of infection by avian influenza virus in humans can be treated with the same prescription drugs that are used to treat infections with seasonal influenza viruses in humans. These drugs are called “antiviral drugs for influenza”.

Outbreaks of avian influenza occur among birds from time to time. When outbreaks of deadly avian influenza occur in poultry, the country’s Ministry of Agriculture works with the pharmaceutical industry and other partner countries to contain the outbreak and prevent it from spreading to other birds. The Centers for Disease Control and Prevention work to protect public health during these outbreaks.
The risk to the public from avian influenza outbreaks is low; however, because other avian influenza viruses have infected people, it is possible that these viruses could infect humans.
The risk depends on the exposure. It is believed that people who do not have contact with infected poultry or contaminated surfaces have very low risk or no risk of infection. It is believed that people who have close contact or prolonged, unprotected, with infected birds or polluted environments have a greater (though probably still low) risk of infection.
Infections of influenza (flu) avian in people are rare, but possible. The majority of the reported cases of infection of avian influenza in people have been having unprotected contact with infected birds or contaminated surfaces.
