Fourth US Bird Flu Case Detected in Colorado Human

From the heart‌ of SALT LAKE CITY, we bring you news of a fresh ⁣human bird flu case in the U.S., this time discovered in a dairy worker from Colorado. This marks the fourth human case ​of the highly pathogenic avian influenza linked to an outbreak among U.S. dairy cows, and it’s the furthest west ⁢the virus has been detected.

Earlier cases were identified‌ in Texas ‌and Michigan,​ as‍ per the data from the Centers for Disease Control and Prevention (CDC). ⁤The CDC made the announcement of this new case on Wednesday. ​The dairy worker, who contracted the infection in April,​ has since received treatment⁣ and made a full recovery.

The H1N5 strain of avian influenza has proven fatal for some people globally. However, in relation to this outbreak, the cases‌ have manifested as pink eye in individuals who work in close proximity with the infected dairy herds.

As of Wednesday, the Department of Agriculture has ⁣reported that 139 dairy‌ herds across⁢ 12 states have tested ⁤positive for bird flu.⁤ These states include Colorado, Idaho,​ Iowa, Kansas, Michigan, Minnesota, New Mexico, ‍North​ Carolina, Ohio, South Dakota, Texas, and‌ Wyoming.

Efforts to Monitor the Spread

The CDC has been diligently monitoring influenza surveillance systems, especially ⁣in the affected states. So far, there has been ⁤no indication of ‌unusual influenza activity in people, ‍including in syndromic surveillance. The CDC has stated that the risk to humans from this outbreak is considered low.

As part of its monitoring efforts, the CDC maintains a wastewater map of the country, showing levels of influenza A detection over the past two weeks. This includes bird flu, but does not distinguish it from other influenza A strains. It also does not specify ​whether the virus samples originated from animals or‌ humans. As the CDC explains, “It could come from a human or from an animal like a bird or an animal product, like milk from an infected cow.”

As reported by NBC, “The CDC recommends that ⁣anyone in contact with dairy ‌cattle‌ wear protective equipment, including safety glasses, waterproof aprons, and ‌boots that can be sanitized.”

Officials from the USDA, ‌Food and Drug Administration, and CDC have⁤ confirmed that while traces of avian flu were found in milk samples from⁣ infected dairy cows, pasteurized milk has been tested and deemed safe for human consumption. Similarly, testing of dairy,⁣ beef, and poultry products has shown that they are safe to eat, provided they are handled correctly and cooked‍ thoroughly, as previously reported by ⁣Deseret News.

Animal Infections

While bird flu is most commonly found in birds, it has also been detected in ‍a range of animals, from⁢ sea lions to bears, and even in Idaho alpacas, North American⁤ river otters, Virginia possums, a couple of Utah mountain​ lions, and a red fox.

As reported by Deseret ⁣News, “Avian influenza in the ‍United States has been detected in big cats, mountain lions, bobcats, brown bears, black ⁢bears and polar bears, bottlenose dolphins, grey seals, harbor seals, ​red ‌foxes, coyotes, fishers, American martens, North American river otters, ​raccoons, skunks, Virginia possums and Abert’s squirrels. There have been outbreaks in cattle ⁣and in ‍mink. But most of the ‌wild mammal infections are considered ‘dead‍ end,’ meaning a mammal ate an infected bird, got infected and died ⁤without contributing to the spread of the virus.”

However, there’s no evidence to suggest‍ that the virus has mutated in a way that would facilitate easy transmission to or among ⁣humans. Health officials are keeping a close eye on the ‌situation. For‍ a pandemic to occur, the CDC stated that “sustained‍ person-to-person spread is needed.”
