Bird flu virus probably mutated in Louisiana patient, CDC says
The CDC said Thursday its analysis of samples from a Louisiana patient with bird flu showed mutations not seen in samples from an infected backyard flock
CDC: H5N1 mutations in severely ill patient could boost spread, but risk remains low
The genetic analysis of the H5N1 avian flu virus in specimens from the nation's first severely ill hospitalized patient in Louisiana reveals mutations that may enable upper-airway infection and greater transmission, concludes a technical summary from the Centers for Disease Control and Prevention (CDC).
CDC Issues Update on Bird Flu 'Mutations' in Humans
The Centers for Disease Control and Prevention (CDC) has identified mutations in a strain of the avian influenza virus H5N1, also known as bird flu, found in a Louisiana patient.The mutations were discovered after samples from the patient were analyzed,

CDC: Bird flu virus shows mutations in first severe human case
Growing concerns surrounding the transmission of H5N1 bird flu. The CDC reports that samples collected from a severely ill patient in Louisiana showed signs of mutation, as they differ from the samples collected from sick and dead birds believed to have infected the man in the first place.
Virus in Louisiana bird flu patient shows mutations that could increase transmissibility: CDC
The patient was likely infected after having contact with sick and dead birds in a backyard flock, the US Centers for Disease Control and Prevention said earlier this month.
Bird flu mutations in the US's first severe H5N1 case may boost the virus's ability to infect humans
Genetic analysis of H5N1 bird flu viruses from a severely ill patient in Louisiana revealed multiple mutations that may enhance the virus’s ability to bind to human upper airway cells, the Centers for Disease Control and Prevention (CDC) reported on Thursday.
Bird flu virus in Louisiana patient likely mutated to be more transmissible, CDC says
The agency, in its latest update released Thursday, said the mutations were not found in samples taken from wild birds, suggesting the virus changed over the course of the patient’s infection.
Bird flu mutations raise fears of a broader outbreak
Scientists with the Centers for Disease Control and Prevention have identified mutations in H5N1 bird flu infections — in hospitalized patients in Louisiana and British Columbia — that may enhance the virus’ ability to infect humans,
Bird Flu Samples From Very Ill Patient Had ‘Concerning’ Mutations
Tiny genetic alterations could help the bird flu virus enter cells in the upper respiratory tract, the C.D.C. said. But there is no sign that mutations are widespread in nature.
