France just raised its bird flu alert to "high" nationwide. Not just France, but Germany too raised alarm over bird flu, and have linked the risk to poultry farms as "high" as cases continue to rise across Europe. The French agriculture ministry said that poultry farms are now required to keep their birds indoors and that authorities must aim "to strengthen surveillance and prevention measures" against the virus. Reuters reported that "This decree was issued following evidence of infection among migratory wild birds in Europe, including France, and the confirmation of several outbreaks in poultry farms. So far, two bird flu outbreaks have been detected on poultry farms and three backyard flocks, the ministry said in the decree. A first case had ben detected in mid-October at a pheasant and partridge breeding farm in northern farm."In Germany too, authorities have raised the risk level after several people came into contact with infected birds and other animals. This has raised the risk of the virus, and the fact that it could mutate and spread much more easily among people. This has also caused a concern among global health experts. Other European countries which have also taken steps to address bird flu include the Dutch agriculture ministry that detected an outbreak on poultry farm, and lead to the culling 71,000 birds and also ordered to keep birds indoors.In recent years, tens of millions of birds have been culled in Europe to prevent the virus from spreading. “The risk to human health in the EU/EEA is currently considered very low,” the European Centre for Disease Prevention and Control (ECDC) said in a press release.What Is Bird Flu?Avian influenza, or bird flu, is a virus that affects birds, especially chickens, ducks, and wild waterfowl. This can spread fast through bird droppings, feathers, and contaminated surfaces. Since it spreads fast, so it can easily sneak into poultry farms, where thousands of birds live close together, and could give the virus the perfect chance to multiply and mutate. Can Humans Get Bird Flu?While humans can get bird flu, the cases are rare. However, when it happens, it usually happens to those who work at poultry farms, or live near to them. Those who handle birds on a day to day basis, like market sellers, or vets are also at a higher risk. However, one of the bird flu strains, the H5N1 is very dangerous and it can cause serious illness in humans if it jumps species. A few signs and symptoms which resemble those of regular flu initially, high fever, cough, sore throat, can sometimes turn extremely severe, leading to pneumonia or breathing problems, which can also be fatal. However, human-to-human spread is extremely uncommon, and health experts say there’s no need for panic.
