Concerns about human spread arise as bird flu patient exhibits virus mutations.

Last week, the U.S. Centers for Disease Control and Prevention (CDC) announced that the patient in Louisiana who was hospitalized with severe bird flu illness had a mutated version of the virus.

The possibility of the virus spreading from human to human is suggested by the patient's mutated virus.

The CDC compared the genomic sequences of the H5N1 virus collected from the patient with those of infected dairy cows, wild birds, poultry, and other animals, according to the agency.

The CDC stated that a low frequency mutation was found in the hemagglutinin gene of a patient's sample, which was not present in poultry samples collected on their property, indicating that the changes occurred after infection.

"Although infrequent in humans, low frequency changes have been reported in previous cases of A(H5N1) in other countries and typically occur during severe disease."

Health officials recommend ongoing genomic surveillance in people and animals, taking measures to control bird flu outbreaks in dairy cattle and poultry, and taking precautions to prevent infection when exposed to infected animals or environments.

The CDC maintains that the risk to the general public is still low.

Samuel Scarpino, director of AI and life sciences and professor of health sciences at Northeastern University in Boston, confirmed to Planet Chronicle Digital that the same mutations were not present in viral genomes sampled from backyard birds that presumably infected the individual.

"The presence of mutations in the human patient but not the backyard birds indicates that the mutations developed during the course of the individual's infection."

Planet Chronicle Digital reported on Dr. Marc Siegel's thoughts on the significance of the finding, as he is a clinical professor of medicine at NYU Langone Health and a senior medical analyst at Planet Chronicle.

"Each human infection represents a spin of the epidemic roulette wheel."

The H5N1 bird flu virus found in the Louisiana patient had a mutation that facilitated its entry into the upper airways, but this mutation has been observed previously.

The doctor reported that there have been no reports of the Louisiana patient transmitting the virus to other humans.

Siegel stated that based on previous research, we are aware of the mutations to monitor for their potential to spread among humans.

He emphasized the need for extensive surveillance among domestic poultry and dairy cattle.

Scarpino acknowledged that although the mutations are "worrisome," they "probably do not pose a greater threat to the public."

The individual who was infected with H5N1 from wild birds in Canada experienced similar events, which are mutations that increase the risk in humans, as have occurred during previous H5N1 outbreaks outside the U.S. and Canada, according to the source.

"There is no evidence to suggest that the person in Louisiana spread the infection to others."

The doctor warned that the more people the virus infects, the greater the likelihood of similar mutations occurring and causing a "chain reaction" in humans.

Scarpino stated that each human infection is a spin of the epidemic roulette wheel.

"To eradicate H5N1 infections in agricultural populations and comprehend why wild birds remain infected, we must take proactive measures."
