CNN —Whether from Miami, New York, Seattle or more, millions of Americans pack aboard cruise ships on vacation. That’s the highest number of norovirus outbreaks on cruises recorded since 2012, with almost half of the calendar year left to go. Still, to prevent the spread of norovirus, Schaffner recommends that cruise passengers take extra precautions and wash their hands thoroughly with soap and warm water. According to data from the CDC’s Vessel Sanitation Program, the number of norovirus outbreaks on cruise ships docking at U.S. ports had years of steady decline after 2015. Overall rates of acute gastroenteritis on cruise ships in the U.S. also decreased from 2006 to 2019.

[1/3] The International Space Station (ISS) is photographed by Expedition 66 crew member Roscosmos cosmonaut Pyotr Dubrov from the Soyuz MS-19 spacecraft, in this image released April 20, 2022. "A weaker immunity increases the risk of infectious diseases limiting astronauts' ability to perform their very demanding work in space. Gene expression in 247 genes in leukocytes was at about one third the normal levels while in space, the study found. Before this paper, we knew of immune dysfunction but not of the mechanisms," said study co-author Guy Trudel, an Ottawa Hospital rehabilitation medicine specialist. Discovering altered gene behavior in leukocytes is "a significant step toward understanding human immune dysregulation in space," Trudel added.

Emily Oster is sitting in the back of a car, checking her Garmin watch as we lurch through rush-hour traffic toward the Holland Tunnel. A self-described expert in data, Oster uses her economics training to dig into studies on things like circumcision and screen time and translate them for popular consumption. There doesn't seem to be much of a gap between the way Oster presents herself in her books and newsletters and the way she conducts her life. Unsurprisingly, economics informs every aspect of the way Oster sees the world. When Oster was a toddler, her mother told a Yale colleague that Oster often talked to herself before falling asleep.

The ultra-wealthy are betting on tech and science breakthroughs to live longer. Longevity expert Dr. Peter Attia explained why preventative care like that still isn't widespread. The ultra wealthy have been shelling out to live longer for some time. In his view, there's a key obstacle standing in the way of your long-term health, ironically: the U.S. healthcare system. Attia's definition of longevity is a function of lifespan, the number of years you live, and healthspan, how well you can live them.

The Expose article says that its central claim is based on a “cherry-picked” list of conditions associated with AIDS and HIV infection. Any increase in the incidence of the listed conditions “would not necessarily be proof that the COVID-19 vaccines cause weakened immune systems,” Mimiaga noted. The claim that COVID vaccines can cause “vaccine-acquired immunodeficiency syndrome” or “VAIDS” has been shared since 2021. Similar claims that COVID vaccines cause HIV infections, AIDS or AIDS-like immune weakening have also been debunked (here), (here). The posts stem from a story that uses unreliable data to falsely suggest a link between COVID vaccines and AIDS-associated diseases and cancers, according to independent health experts.

CNN —A team of researchers excavating mass burial sites in England have detected the DNA of the bacteria that caused the plague in human skeletal remains — and they are the oldest known cases of the disease in Great Britain. The bacterial DNA is thousands of years more ancient than the oldest strain uncovered prior to this latest finding. When it comes to the disease, there is a lot that scientists still don’t know — including how it spread, Swali said. And science may never truly know the severity of the plague 4,000 years ago when it came to humans, Roberts said. And while there are historical records of plague outbreaks, ancient DNA could potentially give us a look even further back, Swali said.

The HPV vaccine protects against the strains that cause most HPV-related cancers. But not every country has the same vaccination options, which is part of the reason WHO has been pushing to change the way doctors give the HPV vaccine. A one-and-done approach to the HPV vaccine could be a huge help around the world, experts say. But she’d also like more people to get the HPV vaccine. So I think that’s really, really important,” Abraham said.

Months prior, Glaser and her team were implementing the school’s Covid-19 testing program, using antigen nasal swab tests. It’s not as simple as just handing those things out at school and having the kids do them,” said Glaser, who oversaw antigen testing programs at some California public schools. For now, Glaser and her colleagues described in a new study the lessons they learned from the Covid-19 dog screening pilot program that they launched in some California K-12 public schools. In comparison, Covid-19 BinaxNOW antigen tests have been shown in one real-world study to demonstrate 93.3% sensitivity and 99.9% specificity. The pilot program within California public schools also has left Edwards with hope for future opportunities in which canines can help detect disease in humans.

The Food and Drug Administration's independent panel of advisors recommended full approval of Pfizer's Covid-19 antiviral pill Paxlovid for high-risk adults 16-1 on Thursday, but flagged potentially harmful drug interactions. The FDA first made Paxlovid available in December 2021 for emergency use in high-risk individuals ages 12 and up. More than half of Paxlovid-eligible Medicare and Veterans Affairs patients are on medications that have drug interactions with Paxlovid, according to an FDA review of safety surveillance data. Roughly 74% of Paxlovid prescriptions were from adult primary care practitioners who may not be experienced with managing the possible adverse drug interactions, the FDA review added. To complete a full course of the drug, patients must take three Paxlovid pills twice a day for five days.

☆ Scientists are modifying catfish with alligator DNA to create hybrids for human consumption

Scientists at Auburn University injected alligator DNA into farm-raised catfish. They hope the new and less disease-prone catfish will one day be sold for human consumption. A group of scientists at Auburn University published a paper in January detailing their efforts to genetically modify catfish with the cathelicidin gene of an alligator. The gene, which was added using CRISPR, heightened disease resistance among the catfish in comparison to wild catfish. However, researchers hope that the alligator and catfish gene-editing can be used in tandem with other catfish breeding techniques to help farmers with their catfish yields.

More than 40 million egg-laying hens have been culled in the U.S. alone, causing the price of eggs nationwide to skyrocket, Lorenzoni said. Months earlier, the “bird flu” outbreak drove the cost of turkey meat to record highs. Poultry can become infected through direct exposure to wild birds but more likely from fecal matter that contaminates the ground around farms or yards. Many migrating birds are not sickened by bird flu, which means it’s not well understood just how widespread it is in the wild, Lorenzoni added. The sun can, for instance, naturally disinfect surfaces while gloomier days help viral particles survive on surfaces contaminated by infected bird poop, Lorenzoni said.

After two years of milder flu seasons, here is a reminder of what the flu is—and what to do if you get it. This flu season hit earlier and harder than those of the past couple of years, doctors say. The reason is likely because of the cyclical nature of the flu and the lifting of Covid precautions such as working from home, wearing masks and having smaller social gatherings, says Robert Frenck , a pediatrician in the division of infectious diseases at Cincinnati Children’s hospital in Ohio.
