Bird flu, what it is and what are its risks to humans. “The real danger would be a leap in species.”

A protection zone and a monitoring zone have been set up by Lazio region to outbreak Bird flu check before Asl Roma 3 On a poultry farm Ostia. Protection zone “with a radius of 3 km from the breeding site of the influenza outbreak” and a control zone “with a radius of 10 km”. But what is bird flu? What are the risks of infection experienced by humans? The Higher Institute of Health explains it clearly, and also provides answers to frequently asked questions on its website.

Bird flu, what is it and what are its risks to humans

“Bird influenza was first identified in Italy more than a century ago, and is a disease caused by a type A influenza virus,” the ISS explains: “It spreads all over the world, and bird flu has completely different manifestations, from mild to severe forms. Pathogenicity and infectiousness that generate acute epidemics.White ducks, which have been identified as a source of infection for farmed poultry, are considered nature reserves for different subtypes of avian influenza virus.In Asian countries, a prominent role in the spread of the virus has been identified in the sale of live poultry to markets.Moreover Viruses can be transmitted from one company to another through mechanical means, contaminated tools and implements, machinery, feed, cages, or even operators’ clothing.”

The presence of the H5N1 virus in chickens, according to the Higher Institute of Health, identifies two major risks to human health. The first is the risk of direct infection if the virus passes from chickens to humans. In some rare cases, in fact, avian influenza viruses succeeded in infecting men who had been exposed to high amounts of the virus.” The second danger “is that the virus, under appropriate conditions, can mutate into a new virus that has the ability to easily transmit itself from one person to another. To become truly dangerous to humans, these viruses must acquire the ability to easily pass from one human being to another, that is to do what is calledSpecies LeapWhich hasn’t happened yet. The emergence of a new virus may cause an influenza epidemic throughout the world.” However, the virus is not easily transmitted from birds to humans. Transmission from chicken to human “requires very close contact, and the main modes of infection are direct contact with infected poultry or surfaces and objects contaminated with poultry faeces.”

But who are the people most at risk? According to the Higher Institute of Health, “Anyone who keeps poultry or butchers them may come into contact with sick animals. People who carry live poultry and veterinarians are also likely to be at risk. The recommended precautionary measures for these occupational groups are annual vaccination against human influenza and washing their hands.” with soap and water after contact with poultry.More recommendations, such as the use of individual protection measures, apply only to workers in areas where H5N1 or other highly pathogenic avian viruses have been isolated.
