A genetic analysis suggests the bird flu virus mutated inside a Louisiana patient who contracted the nation’s first severe case of the illness, the U.S. Centers for Disease Control and Prevention said this week.

Scientists believe the mutations may allow the virus to better bind to receptors in the upper airways of humans — something they say is concerning but not a cause for alarm.

Michael Osterholm, a University of Minnesota infectious disease researcher, likened this binding interaction to a lock and key. To enter a cell, the virus needs to have a key that turns the lock, and this finding means the virus may be changing to have a key that might work.

“Is this an indication that we may be closer to seeing a readily transmitted virus between people? No,” Osterholm said. “Right now, this is a key that sits in the lock, but it doesn’t open the door.”

The virus has been causing sporadic, mostly mild illnesses in people in the U.S., and nearly all of those infected worked on dairy or poultry farms.

The Louisiana patient was hospitalized in critical condition with severe respiratory symptoms from bird flu after coming in contact with sick and dead birds in a backyard flock. The person, who has not been identified, is older than 65 and has underlying medical problems, officials said earlier this month.

The CDC stressed there has been no known transmission of the virus from the Louisiana patient to anyone else. The agency said its findings about the mutations were “concerning,” but the risk to the general public from the outbreak “has not changed and remains low.”

Still, Osterholm said, scientists should continue to follow what’s happening with mutations carefully.

“There will be additional influenza pandemics and they could be much worse than we saw with COVID,” he said. “We know that the pandemic clock is ticking. We just don’t know what time it is.”

NEW ORLEANS (WVUE) – New census numbers show international immigration was a major driving factor of population growth across the United States, contributing to Louisiana’s first population increase in years.

Nationally, immigration accounted for 84% of the nation’s population growth between last July and this July.

In Louisiana, the population grew by just under 10,000. The numbers reveal that about 23,000 more people moved into Louisiana from other countries than people from Louisiana to other countries.

Louisiana lost a net of 17,000 people to other American states.

On the day after Christmas, immigration activists gathered at the steps of City Hall to send a message to Louisiana leaders.

Rachel Taber with Unión Migrante served as an interpreter for Alfredo Salacar of Mexico.

“For all of the anti-immigrant politicians that are supposedly Christian, we want to remind them that Jesus himself was an immigrant,” Salacar said.

Immigration activists said Jesus didn’t come from the White House, a palace or a mansion along St. Charles Avenue; he was born in a stable as his migrant parents who were forced to flee wandered a foreign country.

Taber said many undocumented families who’ve settled in New Orleans had to flee political tyranny, violence and poverty.

“Louisiana is an incredible place everyone wants to visit because of our rich gumbo of people who made a life here: Cajuns, Sicilians, Germans, Irish, Spanish Islenos, Jewish people, resilient Africans and Indigenous people who kept their culture alive despite so much injustice. This recent wave from Central and Latin America is just the newest flavor to add to the family recipe,” Taber said.

Unión Migrante is fighting against racial profiling and the separation of families.

“That’s not a good use of our resources. We want to see families remaining together,” Taber said.

During Thursday (Dec. 26) night’s Christmas Posada and vigil, the local immigration activist group called on Louisiana leaders to take a more pro-immigration stance. At the Hispanic cultural celebration, they also demanded the federal oversight of the New Orleans Police Department continue.

“We’re not criminals. We are an asset,” said Yareli Andino. “If just one opportunity would be given, I think a lot of things could change.”

This holiday season, they are asking people to open their hearts and homes.

“We contribute, we work, we’re here. We rebuild this community after every hurricane comes and destroys it. We work in your hotels. We work in your homes. I personally work in construction, and I’ve been in the homes of many of these same elected officials,” said Salacar. “We know that threats are coming our way… We have a human right to migrate and it’s disgusting to see politicians not only making money off of immigrants but turning us into a political pawn for their own ambition.”

Taber said, “Taylor Swift weekend, the Super Bowl, and Mardi Gras would not be possible” without immigrants.

Members of Unión Migrante said Jesus’ life is an example of empathy, compassion, peace and humility, displaying a deep love towards our neighbors and those most vulnerable.

In a statement, Sgt. Kate Stegall said, “The Louisiana State Police regularly partners with local, state, and federal law enforcement agencies to enforce laws throughout Louisiana. Additionally, LSP Troopers are assigned to federal task forces, where they focus on enforcing federal laws. In these collaborative efforts, Troopers uphold a high standard of professionalism and ensure respectful and effective interactions.”

In a ride-along earlier this month, ICE told Fox 8 these alleged raids and indiscriminate sweeps couldn’t be further from the truth.

ICE representatives said the federal agency is prioritizing criminals and those who pose a threat to national security.
