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.
CDC Flags Mutations in H5N1 Bird Flu Virus Amid Heightened Surveillance
The Centers for Disease Control and Prevention (CDC) has identified mutations in the H5N1 bird flu virus that may increase its ability to infect humans. These mutations, found in the hemagglutinin (HA) gene,
Bird flu samples show mutations that may make it easier to spread to people, CDC reports
Genetic analysis suggests the bird flu virus has the capacity to mutate in ways that could make it more transmissible to humans, the CDC reported.
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,

The CDC has declared the first “severe” case of H5N1 bird flu in the U.S., according to a press release published Wednesday. The good news? The person who contracted the virus appears to have gotten it from backyard poultry,
Genetic mutations in H5N1 bird flu raise transmission concerns
A genetic analysis of samples from the Louisiana patient who was recently hospitalized with the country’s first severe case of H5N1 bird flu shows that the virus likely mutated in the patient to become potentially more transmissible to humans,
Bird flu virus in 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 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.
Virus in Louisiana bird flu patient shows mutations that could increase transmissibility to humans, CDC analysis finds
A genetic analysis of samples from the patient in Louisiana recently hospitalized with the country’s first severe case of H5N1 bird flu show the virus likely mutated in the patient to potentially become more transmissible to humans,
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.
