As the world sputters amid a global coronavirus pandemic that may have originated from bats in China, researchers released a study on Monday indicating that pigs could transmit a pandemic-level flu strain to humans.The Chinese and British based researchers, who published their findings in the Proceedings of the National Academy of Sciences on Monday, said that G4 EA H1N1 viruses in pigs should be closely monitored in human populations, especially among workers in the swine industry.The researchers said that pigs are intermediate hosts for the strain of influenza, which researchers are concerned could spread to humans. A further concern is that humans could spread the virus to other humans, prompting a pandemic. While the study notes that the virus had spread to workers in the swine industry, it likely has not been transmitted from humans to humans.“G4 viruses have all the essential hallmarks of a candidate pandemic virus,” the team of UK researchers wrote.The researchers said G4 viruses bind to human-type receptors, produce much higher progeny virus in human airway epithelial cells, and show efficient infectivity and aerosol transmission in ferrets.While the study indicates cause for some concern, Martha Nelson, an evolutionary biologist at the U.S. National Institutes of Health’s Fogarty International Center, told Science Magazine the chances of a pandemic from G4 viruses are “low,” but added that no one knew the pandemic risk of H1N1 until 2009.“Influenza can surprise us,” Nelson told Science. “And there’s a risk that we neglect influenza and other threats at this time” of COVID-19.Nelson added to Science that given the warning, it would be ideal to produce a human G4 vaccine as the world still needs to be vigilant on other pandemics besides COVID-19.Domestically, the University of Missouri reviewed the research. 1855

As President Donald Trump and Republicans attempt to reverse the results of last week’s presidential election in Pennsylvania, a significant case often cited by Trump’s supporters has lost steam.The House Oversight Committee, led by Democratic Congresswoman Carolyn Maloney, announced that Richard Hopkins has “recanted” his claim of election fraud in Erie County, Pennsylvania. Hopkins had previously accused fellow USPS employees of changing the date of ballots submitted after the election. 501

At least eight nursing home residents have died in Hollywood, Florida, according to the New York Times and NBC News.The deaths may be due to the loss of the home's air-conditioning after Hurricane Irma struck Sunday, according to CNN affiliate WPLG. The causes of death are still being investigated, Hollywood Police Chief Tomas Sanchez said."We are conducting a criminal investigation (and) not ruling anything out at this time," Sanchez said at a press conference Wednesday. 489

At least 285 U.S. children have developed a serious inflammatory condition linked to the coronavirus and while most recovered, the potential for long-term or permanent damage is unknown, two new studies suggest.The papers, published online Monday in the New England Journal of Medicine, provide the fullest report yet on the condition.The condition is known as multisystem inflammatory syndrome in children. It is considered uncommon and deaths are rare; six children died among the 285 in the new studies.Including cases in Europe, where it was first reported, about 1,000 children worldwide have been affected, a journal editorial said.The federal Centers for Disease Control and Prevention’s case definition includes current or recent COVID-19 infection or exposure to the virus; a fever of at least 100.4 for at least 24 hours; severe illness requiring hospitalization; inflammatory markers in blood tests, and evidence of problems affecting at least two organs that could include the heart, kidneys, lungs, skin or other nervous system.Digestive symptoms including nausea and diarrhea are common. Some children may have symptoms resembling Kawasaki disease, a rare condition in children that can cause swelling and heart problems.At least 35 states have had cases, and they seem to crop up a few weeks after local COVID-19 activity peaks, said Dr. Adrienne Randolph of Boston Children’s Hospital. She is a lead researcher for a multistate study that includes CDC scientists. The second paper involved 99 children in New York state, where the first U.S. cases occurred.Combined, the papers show 285 cases from March thru mid to late May but Randolph said additional U.S. children have been diagnosed in June.Most had current or recent COVID-19 infections but had previously been healthy.About 80% of children in the multistate study had heart-related problems, which included coronary aneurysms — a bulge in a heart artery that can be fatal.“Those need to be followed up,” Randolph said. “This is a life-threatening concern for a lot of patients.”Most affected children had no other health condition but about 30% were obese. The condition also appears to disproportionately affect Latino and Black children and boys.The average age was 8 years old. Researchers don’t know if adults can be affected.___Follow AP Medical Writer Lindsey Tanner at @LindseyTanner.___The Associated Press Health and Science Department receives support from the Howard Hughes Medical Institute’s Department of Science Education.

Attorney General Jeff Sessions ordered a review Friday into how the Justice Department and FBI respond to indications of potential violence after the bureau said it failed to act on a tip about the shooter in the Parkland, Florida, school massacre.A person close to Nikolas Cruz, the confessed shooter, contacted the FBI on January 5 to report concerns about him, the FBI said in a statement Friday. But the bureau did not appropriately follow established protocols in following up on the tip."The information was not provided to the Miami Field Office, and no further investigation was conducted at that time," the statement said.The stunning admission -- which prompted Florida Gov. Rick Scott to call on FBI Director Christopher Wray to resign -- is sure to raise further questions about whether the FBI could have prevented the shooting at Marjory Stoneman Douglas High School, which left 17 dead.  915
