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.
The CDC said it sequenced samples of the virus from the first severe case of bird flu in the country, which was identified in Louisiana last week.
The tests detected mutations that are believed to help H5N1 bind to cell receptors found in the upper respiratory tract of humans. Typically, bird flu viruses target a type of receptor that is rare in human airways, which can help explain why H5N1 rarely infects people and does not spread person-to-person when it does.
The CDC also noted that the mutations were not present in an infected bird on the patient’s property, suggesting they developed after the patient was infected.
‘These changes were likely the result of the virus replicating in the patient during advanced disease, rather than being transmitted at the time of infection,’ the report stated.
Angela Rasmussen, a virologist, posted on the social media site X that the ‘H5N1 situation remains grim’ and that ‘we need fewer humans infected.’
‘We don’t know what combination of mutations would lead to a pandemic H5N1 virus and there’s only so much we can predict from these sequence data,’ Rasmussen wrote. ‘But the more humans are infected, the more chances a pandemic virus will emerge.’
Since the mutations were detected at low levels, the CDC emphasized that the risk to the general public from the ongoing H5N1 outbreak remains low and unchanged.
This type of mutation was previously seen in a separate severe case in British Colombia last month.
So far, there is no evidence the Louisiana patient passed the virus on to others.
The news comes as 65 human cases of bird flu have been confirmed in the U.S. this year, with California reporting the highest number at 36 cases.
Right on time for masks, social distancing…… warp speed 2.0. Let me guess…… 99.2% survivability rate from the “birdie” infection? The vaccine will lessen the effects of the 99.2% survivable illness. However, sudden death from vaccine rises to 25%. Turbo cancers up to 45%. Heart attacks up yo 85%.
More stimulus checks as we are locked down again by “stupid leading the stupid” It’s all to predictable at this point.
ed note–In your list of all the ‘predictables’, you left out the one ‘possible’ that all should be considering right now, which is that this time it will not be a ‘scam’ as it was last time, but rather the real deal.
And as it stands now, the survivability rate for humans infected with H5N1 is not 99.2% as you listed. The actual numbers are 50%+ mortality rate, and all can rest assured that prior to this thing being released from the bioweapons lab in Israel that they made sure to increase that number even higher.
