The new case turned up in Michigan. The worker tested positive with the H5N1 strain of bird flu, one that public health authorities worry could turn virulent in humans. He tested positive for the virus after spending time around cows that were also infected, according to the CDC’s public statement on the matter. The worker was being monitored because he came into contact with animals who were known to be infected. He developed symptoms and immediately contacted local health officials. Medical personnel collected test samples and confirmed the infection.
Initially, bird flu was ruled out when a nasal swab returned negative results. However an eye swab, which was sent to a CDC lab for testing, turned up positive for an H5N1 infection. A second nasal swab was subsequently taken, but it also returned negative results.
Bird flu also turned up in the body of another dairy worker from earlier this year, was discovered when a Texas farm hand bled from his eyes after working with cows that carried the H5N1 virus, as reported by the New York Post.
Previously, health officials believed that H5N1 posed little risk to humans. Now, they’re raising the alarm that a new dangerous pandemic could be on the horizon. To minimize this risk, the CDC is recommending that people avoid, as much as possible, long, close, and unprotected contact with sick and dead animals, including wild birds, poultry, cows, and other domesticated birds. Those who keep or work with livestock are believed to be at elevated risk of exposure.
It would also be wise, the statement continues, to avoid unprotected exposure to animal feces, bedding and litter, and raw and/or unpasteurized milk. The CDC is also advising people to avoid any materials that have been in close proximity with, or been touched by, animals or birds who are suspected, or known, to be carrying the H5N1 virus.
