Both workers had been in contact with cattle before becoming ill. CDC says.

A Michigan dairy worker has become the first to test negative for the highly pathogenic avian influenza strain known as H5N1 after submitting nasal swab results to state health officials.

“This virus is being closely monitored and there are currently no signs of sustained human-to-human transmission.”

Meanwhile, health authorities announced the first confirmed case of human avian influenza in Australia, in a child who had recently travelled to India. he said Wednesday.

The child fell ill in March and suffered a severe infection but has reportedly since recovered.

In April, shortly after the bird flu virus was found in U.S. dairy cows, a Texas dairy worker was treated for bird flu. Officials said the virus had likely been circulating among the cows for four months. The worker suffered eye irritation but has since recovered.

Overall, the Michigan patient marks the third human case of avian influenza reported in the U.S. A poultry worker in Colorado also tested positive in 2022.

In other countries, bird flu cases can be more severe, leading to pneumonia and death.

The CDC said it plans to monitor dairy cows and poultry, and staff who come into contact with those animals, for the virus through the summer.
