Severe case of H5N1 bird flu detected in US, CDC confirms
A recent report from the U.S. Centers for Disease Control and Prevention has confirmed the hospitalization of a patient with a severe case of H5N1 bird flu in Louisiana. This marks the first known instance of a severe human infection associated with the H5N1 virus in the United States.
The CDC announced the confirmation of this case on Friday, highlighting the significance of this development. While the agency acknowledged that sporadic cases of severe H5N1 bird flu illness in humans are not unexpected, it emphasized that the risk to the public remains low.
The genetic analysis of the virus isolated from the infected patient revealed that it belongs to the D1.1 genotype, which has been previously identified in wild birds and poultry in the U.S. This genotype has also been linked to recent human cases in British Columbia, Canada, and Washington state.
Unlike the B3.13 genotype, which has been associated with cases in dairy cows, multiple states, and some poultry outbreaks, the D1.1 genotype represents a distinct strain of the H5N1 virus. The CDC noted that there have been a total of 61 reported human cases of H5 bird flu in the U.S. since April, underscoring the ongoing vigilance required to monitor and respond to emerging infectious diseases.
The emergence of a severe human infection linked to the H5N1 virus underscores the importance of continued surveillance and preparedness efforts to mitigate the spread of bird flu. The CDC’s prompt identification and response to this case reflect the agency’s commitment to protecting public health and safety.
As the investigation into this case continues, health officials are closely monitoring the situation to prevent further transmission of the virus. The public is advised to remain vigilant and follow recommended precautions to reduce the risk of exposure to bird flu.
