Two dairy workers in Michigan could donate bird flu to their cats for animals in May last year, suggests a new study Published on Thursday by Centers for Disease Control and Prevention.
In one household, infected cats could also transfer the virus to other people at home, but restricted evidence hinder determination of possibilities.
The results come from the study, which was to be published in January, but were delayed by detaining the Trump administration in the field of communication with CDC
A single data table from a modern report appeared online two weeks ago in an article on fires in California, and then quickly disappeared. This strange incident caused public health experts to issue a study.
Experts say that the modern article still leaves the main questions unanswered, including how cats have been infected for the first time and whether workers spread the virus to cats and other people in the household, say experts.
“I don’t think we can say for sure whether he is a Cat-Cat, Human or Kota-Coś-Coś cat,” said Jennifer Nuzzo, director of the Pandemic Center at Brown University School of School of School of School of School of School of School of School of School Public health.
Officials in Michigan began studying two households in May last year, when only internal cats showed respiratory and neurological symptoms, and after death positively checked the virus called H5N1. Officials conducted interviews with the owners of cats and household members and offered to test them for a virus.
The owners of both cats were dairy workers. The first agricultural worker did not work directly from the cows, and the farm was not known for infected herds. But the employee announced that many cats of the barn in the farm have recently died. The employee also informed that he had experienced vomiting and diarrhea before the first house of the household fell ill.
The second agricultural worker reported that he was splashed in the face and eyes with milk and experiencing eye irritation. Both employees refused to test.
“This study provides even more evidence that agricultural workers with high-risk exhibitions can refuse to test,” said Dr. Nuzzo.
“To protect people and overtake this virus, we must remove discouragement to testing patients,” she added. “People should not worry that positive testing will cause financial stress or other personal damage.”
In the household of the first agricultural worker, the first cat who got unwell showed reduced appetite, lack of care, abnormal gait and lethargy and quickly deteriorated. She was killed the fourth day of the disease.
The second cat in the household developed a watery discharge of eyes, quick breathing and reduced the appetite four days after the first cat. This cat recovered and was not tested for a virus. The third cat had no symptoms and tested a negative for the virus 11 days after the first cat.
Neither cats nor people in the household drank unpasteurized milk. How cats could be infected is unclear, but experts said that agricultural workers would probably be infected with H5N1 in their workplace and brought a virus to their cats.
“If you love your cat, you’ll probably give him kiss, if he allows you,” said Kristen K. Coleman, a researcher of infectious diseases at the University of Maryland.
Three people in the household – an adult and two teenagers – tested negative for H5N1. Six days after the first cat fell ill, one of the youth fell ill with a cough, sore throat and body pain, and the other reported a cough assigned to allergies.
But because teens were tested overdue – 11 days after the first cat got unwell – it was not possible that they infect the H5N1 they received from cats, said Dr. Coleman.
Later in May, the PET cat in the second household developed bulky neurological symptoms, including anorexia and minimal movement, and died in one day; After death, the cat positively tested the bird flu.
The owner of the cat transported unpasteurized milk, including farms with known influenza birds. According to the study, the owner “did not wear personal protective equipment (PPE) while servicing raw milk; Recurrent exposures were reported to the splash, eyes and clothes; And he did not remove work clothes before entering the house while returning from work. “
The study was noticed that the cat he got unwell was known for “throwing himself at the owner’s work clothes”.
Dr. Keith Poulsen, director of the Veterinary Diagnostic Laboratory Wisconsin Wisconsin Wisconsin Vetelinary Diagnostic Wisconsin Wisconsin Veterinary Diagnostic Diagnostic Laboratory Wisconsin Wisconsin Vetelinary Diagnostic Laboratory, said, may be a source of infection in clothes.
“At this point, I think that their exposure from raw dairy products is a higher risk,” he said. “There is so much virus on milk.”
Of the 24 members of the veterinary staff, who were potentially exposed to infected cats, seven reported symptoms such as nasal congestion and headache. Only five agreed to test; They were all negative.
Dr. Coleman recommended that veterinarians remain vigilant to the possibility of bird flu infection when they see unwell cats. “Pets owners should not rely on posthumous sampling to get a diagnosis,” she said.
