A Nevada dairy worker who was infected with a new type of avian flu that is different from the version that has spread in the herds of the United States. Since last year he has recovered, federal health officials said Monday.
The disease was considered mild. The main symptom of the person was red redness and irritation, similar to most cases of avian flu associated with dairy cows. The person was not hospitalized and has recovered, according to the US disease control and prevention centers (CDC).
The newest strain had seen before in more than a dozen people exposed to poultry, but this is the first time an infection dates back to a cow. The Nevada dairy worker was exposed on a farm in Churchill County, in the central west of the state, state health officials said.
CDC officials said there is no evidence that the virus has spread from this person to any other person. The agency continues to say that the virus has a low risk to the general public.
Scientists know the avian flu that currently extends through animals, and some people, such as H5N1 type A influenza but there are different strains.
Look | New concerns about avian flu:
California has declared an emergency state on H1N5 avian flu as the virus spreads more widely in dairy herds. While cases are still rare in humans, experts urge those who work with birds and cattle to take precautions.
A version known as B3.13 was confirmed in March after extending to cattle at the end of 2023, scientists said. He has infected 962 her herds in 16 states, the vast majority of them in California.
The newest version, known as D1.1, was confirmed in cattle in Nevada on January 31. It was found in the milk collected as part of a monitoring program initiated in December.
The new case raises questions
That discovery meant different forms of the propagated virus of wild birds in cattle at least twice. Experts said they ask questions about a broader spread and the difficulty of controlling animals and people who work with them.
According to CDC data, at least 68 people in the US. In the USA in the last year, according to CDC data. All but a little handful worked closely with cows or poultry.
Most caught version B3.13. The CDC said previously that version D1.1 had been seen alone in cases in Louisiana and the state of Washington. But on Monday, the agency revealed that the available data indicate that D1.1 last year probably infected a total of 15 people in five states, Iowa, Louisiana, Oregon, Washington and Wisconsin, all related to poultry.
Version D1.1 of the virus was linked to the first death of the United States tied to flu already avian already a serious disease in Canada. A person in Louisiana died in January after developing serious respiratory symptoms after contact with wild and rear birds. In British Columbia, a teenager was hospitalized for weeks with a tracked virus even poultry.
While the risk to the general public is low, CDCs say that aviar flu raises greater threat to people with close or prolonged contact with infected cows, birds or other animals. These people are encouraged to use protection equipment and take other precautions.
