Science: US reports first severe bird flu case: How worried should humans be?

 


The United States has reported its first severe case of bird flu, signaling a notable escalation in the current avian influenza outbreak. A 65-year-old Louisiana resident is in critical condition after exposure to an infected backyard flock.

The case, associated with the H5N1 strain of bird flu, marks the nation's first severe human infection, according to the Centers for Disease Control and Prevention (CDC).

"CDC confirms the first severe case of H5N1 bird flu in the U.S.," the agency announced. "While the source of the infection remains under investigation, it has been established that the patient was exposed to sick and dead birds in backyard flocks."

A Louisiana resident has been identified as the first U.S. case of bird flu linked to a backyard flock. In France, a court has convicted Gisele Polycot's ex-husband in a mass rape case. Meanwhile, Wisconsin officials have released the identities of the victims in the Abundant Life Christian School shooting.

An older Louisiana resident is hospitalized with a "severe" case of avian influenza after exposure to a backyard flock, according to the Centers for Disease Control and Prevention (CDC). This marks the first case among 61 individuals infected with the H5N1 virus in the U.S. this year to exhibit symptoms beyond "mild." The H5N1 strain involved differs from the one affecting dairy farms and some poultry flocks, which is thought to have originated from wild birds earlier this year.

And in the other hand California has declared a state of emergency following the confirmation of a severe H5N1 bird flu case, marking the first such case reported in the United States. The Centers for Disease Control and Prevention (CDC) confirmed on Friday, December 13, that a patient in Louisiana has been hospitalized with a severe avian influenza A (H5N1) infection.

Investigations revealed that the patient had contact with sick and dead birds in backyard flocks, making this the first U.S. case of H5N1 linked to backyard flock exposure. Authorities have not identified any evidence of person-to-person transmission in this case.
