„H5N1 weitet sein Wirtsspektrum ziemlich dramatisch aus, und dabei nimmt es Mutationen auf, die das #Virus in Säugetieren besser funktionieren lassen“, sagte Worobey. Mit dieser gewissen Vor-Anpassung an Säugetiere steige das Risiko für den Menschen. So begännen Pandemien."

As cases climb in the US, do you need another measles shot?
Experts say some children can get vaccinated earlier and adults can get a second dose if the risk is high.Madeline Halpert (BBC News)
The widely accepted theory is that Covid-19 emerged in bats and then jumped to humans, most likely through another animal, or "intermediary host."
As time worn on, scientists have not found a virus in either bats or another animal that matches the genetic make-up of Covid-19, leading some to doubt the theory.

Trügerische Sicherheit: Virenscanner-Apps sind schlichtweg überflüssig
Die Sicherheitsarchitektur von Android/iOS schränkt die Funktionsweise von Virenscanner-Apps stark ein und macht sie im Grunde nutzlos. Schlimmer: Die vermeintlichen Sicherheits-Apps sind Datenschleudern.www.kuketz-blog.de

5 Jahre Corona - Was haben wir aus der Pandemie gelernt? Es wäre ein Fehler, Erkenntnisse aus der Covid-19-Pandemie direkt auf die nächste Krise zu übertragen, meint der Virologe Christian Drosten in dieser neuen Podcast-Staffel. Wie gut ist das Wissen über potenziell pandemische Erreger? Wo stehen wir bei einer nächsten Pandemie womöglich besser da? Daniela Remus und Korinna Hennig aus der NDR Info-Wissenschaftsredaktion sprechen in der ersten von zehn Folgen mit verschiedenen Wissenschaftlern darüber, wie die Forschung vorgeht, wenn ein Erreger mit....

A Louisiana patient is the first person in the US to die as a result of H5N1 infection. The Louisiana health department noted that the person who was infected was over the age of 65 and had underlying medical conditions, which made the person particularly vulnerable to severe disease.

]The ongoing spread of bird flu in the United States has alarmed experts — not just because of human cases causing severe illness, but also due to troubling new instances of infections in cats.

![Instead, the Centers for Disease Control and Prevention (CDC) said the mutations were "likely generated by replication of this virus in the patient with advanced disease," emphasizing that no transmission of the mutated strain to other humans had been identified.
Several experts contacted by AFP cautioned that it was too early to determine whether these changes would make the virus more transmissible or more severe in people.
Angela Rasmussen, a virologist at the University of Saskatchewan in Canada, explained that while the mutation might help the virus enter cells more easily, additional evidence [such as animal testing] would be needed to confirm any effect on transmissibility.
Moreover, similar mutations have occurred in previous critically ill patients without leading to broader outbreaks. "It's good to know we should be looking out for this," Rasmussen said, "but it doesn't actually tell us, [Oh, we're this much closer to a pandemic now]."](https://nerdculture.de/system/media_attachments/files/113/770/318/939/716/868/original/a73dafd158bf2bcd.jpeg "Instead, the Centers for Disease Control and Prevention (CDC) said the mutations were \"likely generated by replication of this virus in the patient with advanced disease,\" emphasizing that no transmission of the mutated strain to other humans had been identified.

A sample of the virus found in a critically ill patient in the United States has shown signs of mutating to better suit human airways, although there is no indication it has spread beyond that individual, authorities report.
An analysis posted by the CDC revealed that a small percentage of the virus in the patient's throat carried genetic changes that could increase the virus's ability to bind to certain cell receptors found in the human upper respiratory tract.
Importantly, the agency noted that these changes have not been detected in birds – including in the backyard poultry flock believed to have been the source of the patient's initial infection.
Earlier this month, officials announced that an elderly Louisiana patient was in "critical condition" with a severe H5N1 infection. And now, a updated @CDCgov technical report on the Louisiana case is out. There are low frequency mutations in HA that indicate adaptation in a human host [specifically this human host].](https://nerdculture.de/system/media_attachments/files/113/770/319/813/726/954/original/3005e6fb2bfe49ce.png "[ImageSource: Centers for Disease Control & Prevention (CDC)]

How the #virus spreads, mutates, and attacks humans
The latest strain is a mutated version of clade I, a form of mpox spread by contact with infected animals that has been endemic in #Congo for decades.
You can see the contrast between those infected in the African region (men and women somewhat evenly) and the rest of the world (almost all men). The variant in Africa can spread through close contact.

"der Ausbruch des #Virus birgt die Gefahr einer #Pandemie. Mehr als 60 Menschen in den #USA haben sich infiziert, v.a. durch Kühe oder Geflügel, die Zahl der Fälle könnte in die Höhe schnellen, wenn sich das Virus so entwickelt, dass es sich von Mensch zu Mensch verbreitet. Die jüngste Nachricht, dass eine Person in Louisiana an der #Vogelgrippe schwer erkrankt ist, zeigt, dass es gefährlich sein kann."

Dies könnte darauf hindeuten, dass das #Virus nach einer #Infektion des Jugendlichen besser in Atemwegszellen gelangen konnte. “Es stimmt mit der Idee überein, dass sich das Virus innerhalb dieser Person entwickelt haben könnte, sagt Hensley."
