You may be knowledgeable about the USDA stamp of approval to fresh meats that you now buy at the supermarket, but this really is simply not their sole function. They generally inspect chicken farms and test domesticated poultry for the disease.
Only at that moment, according to the Center for Disease Control (CDC), there is no dependence on anybody in the USA to utilize a "flu mask". However, obviously, you will find companies that are capitalizing on American fears arising out of the deaths in small villages and towns throughout Asia and the Middle East.
Some providers will provide you with a flu mask, even but some sell a bird influenza prep kit. If you want to buy a flu mask then you can navigate to https://www.u-mask.eu/flu-masks.
Is a bird flu mask or perhaps even a bird influenza preparation kit actually necessary for the average person living in the USA at this time or anytime in the longer term? No, since the breed of bird flu that has killed people will not exist in the United States.
Other forms of bird flu have been found in poultry in the U.S., but only 1 instance involved an individual and he was a USDA employee doing his job, inspecting poultry farms and taking samples once he contracted a weak bird flu virus. Many USDA employees wear protective clothing.
The U.S. government's bird flu preparation involving the USDA and the USGS includes testing wild migratory birds in Alaska and elsewhere to get a specific virus, H5N1.
While collecting the samples, employees might need to put on a bird flu mask, however, they are aware that the herpes virus doesn't transfer easily from birds to humans. Wild birds are mostly unaffected by herpes.
