      A Summer Guide to Covid Testing, Symptoms and Treatment

      by

      Experts say cases could rise in the coming weeks. Here’s what to know about symptoms, testing and treatment.As the so-called “FLiRT” variants of the coronavirus continue to gain traction, doctors and researchers are bracing for a potential rise in cases this summer. KP.2, one of these variants, now accounts for 28.5 percent of cases, and data from the Centers for Disease Control and Prevention shows a small increase in Covid-related emergency room visits and positive tests.Here’s what to know about symptoms, testing and treatment if you do fall ill:Symptoms to watch out forThere’s no evidence that symptoms of the FLiRT variants and other recent strains are any different, said Aubree Gordon, an infectious disease epidemiologist at the University of Michigan.The symptoms still include sneezing, congestion, headaches, sore muscles, nausea or vomiting. Many people also report exhaustion and a general “blah” feeling.In general, the more immunity you’ve built up from vaccination or past infections, the milder your next bout with the virus is likely to be. (Though it’s possible to experience more intense symptoms with a new infection than you’ve had in past Covid cases.)The symptoms of Covid can look similar to those caused by allergies or other infections. The best way to tell the difference is to test.When (and how) to testIn an ideal world, experts said, people would take a Covid test as soon as they develop symptoms or learn they were exposed, and then test again a day or two later. But if you only have a limited number of at-home rapid tests, there are a few ways to maximize their usefulness: Test immediately if you have a fever and a cough, said Dr. Davey Smith, an infectious disease specialist at the University of California, San Diego.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

      Up to 70 Percent of People With Asthma and COPD Go Undiagnosed

      by

      Here’s how to tell if you’re one of them.In spring 2020, Jazzminn Hein received an automated phone call from The Ottawa Hospital in Canada, asking if she or anyone in her household had experienced wheezing, shortness of breath or other breathing problems in recent months. The question caught her attention: Just a week earlier, Ms. Hein, then 24, had gone on a stroll with her mother-in-law and newborn only to end up feeling like her chest was burning.“I realized that I had had breathing issues from a very young age,” Ms. Hein said. As a child, she often had to catch her breath on the sidelines during gym class. As an adult, she frequently had to pause after carrying laundry up the stairs. So Ms. Hein pressed “1” to receive a follow-up call from a nurse.A few months later, as part of a study conducted by researchers at the University of Ottawa, a doctor diagnosed Ms. Hein with asthma.Estimates suggest that 20 to 70 percent of people with asthma or another group of conditions called chronic obstructive pulmonary disease that causes similar symptoms, go undiagnosed.To look for patients with those diseases, researchers placed automated calls to more than a million households across Canada asking about breathing issues. Many people hung up. But the research team talked to more than 38,000 people experiencing such symptoms, and ultimately found more than 500 patients, including Ms. Hein, with either undiagnosed asthma or C.O.P.D who could participate in their clinical trial.Roughly half were told to follow up with their primary care provider and received standard care, such as a short-acting inhaler to be used as needed. The other half saw pulmonologists who frequently prescribed better, long-acting medication and worked with an educator who taught patients how to properly use an inhaler and avoid allergens, provided support to quit smoking, gave exercise and weight counseling, and more. These measures could help reduce symptoms, said Dr. Shawn Aaron, a lung specialist at The Ottawa Hospital and a professor at the University of Ottawa who led the research.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

      What to Know About New Covid Variants, ‘FLiRT’: Symptoms, Vaccines and More

      by

      Experts are closely watching KP.2, now the leading variant.For most of this year, the JN.1 variant of the coronavirus accounted for an overwhelming majority of Covid cases. But now, an offshoot variant called KP.2 is taking off. The variant, which made up just one percent of cases in the United States in mid-March, now makes up over a quarter.KP.2 belongs to a subset of Covid variants that scientists have cheekily nicknamed “FLiRT,” drawn from the letters in the names of their mutations. They are descendants of JN.1, and KP.2 is “very, very close” to JN.1, said Dr. David Ho, a virologist at Columbia University. But Dr. Ho has conducted early lab tests in cells that suggest that slight differences in KP.2’s spike protein might make it better at evading our immune defenses and slightly more infectious than JN.1.While cases currently don’t appear to be on the rise, researchers and physicians are closely watching whether the variant will drive a summer surge.“I don’t think anybody’s expecting things to change abruptly, necessarily,” said Dr. Marc Sala, co-director of the Northwestern Medicine Comprehensive Covid-19 Center in Chicago. But KP.2 will most likely “be our new norm,’” he said. Here’s what to know.The current spread of CovidExperts said it would take several weeks to see whether KP.2 might lead to a rise in Covid cases, and noted that we have only a limited understanding of how the virus is spreading. Since the public health emergency ended, there is less robust data available on cases, and doctors said fewer people were using Covid tests.But what we do know is reassuring: Despite the shift in variants, data from the C.D.C. suggests there are only “minimal” levels of the virus circulating in wastewater nationally, and emergency department visits and hospitalizations fell between early March and late April.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

      Biotech Exec Gets 7 Years in Prison for False Claims About Rapid Covid-19 Test

      by

      Prosecutors said Keith Berman falsely claimed he had invented a blood test that could detect Covid-19 in 15 seconds. His lawyer said he had put “genuine effort” into developing such a test.The former chief executive of a biotechnology company who, during the early days of the pandemic, falsely claimed that he had invented a blood test that could detect Covid-19 in 15 seconds was sentenced on Friday to seven years in prison for securities fraud, federal prosecutors said.From February 2020 to December 2020, the former executive, Keith Berman, 70, of Westlake Village, Calif., engaged in a scheme to defraud people into investing in his company, Decision Diagnostics Corporation, by claiming the test could detect Covid using a finger prick sample of blood, prosecutors said.In March and April 2020, Mr. Berman issued 12 “false and misleading” news releases describing the rapid Covid test, which his company called GenViro, prosecutors wrote. Decision Diagnostics’ stock price jumped by more than 1,500 percent during the period, prosecutors said.In reality, prosecutors said, Mr. Berman had “privately confided in a friend the test could not actually detect Covid-19.”Prosecutors accused Mr. Berman, the sole director of the publicly traded medical device company, of capitalizing on people’s fears about the pandemic in an effort to resuscitate the company’s fortunes.Mr. Berman’s scheme resulted in about $28 million in investor losses, prosecutors said. Mr. Berman was indicted in December 2020, and he pleaded guilty in December 2023 to securities fraud, wire fraud and obstruction of an official proceeding.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

      What Is VO2 Max?

      by

      VO2 max has become ubiquitous in fitness circles. But what does it measure and how important is it to know yours?Fitness is full of numbers meant to help you become faster and stronger. There’s your mile run time, your resting heart rate and measures of strength and flexibility. But perhaps the gold standard is VO2 max.A handful of years ago, the test — which tracks how much oxygen your body absorbs — was an obscure tool mainly used by elite athletes. Today, it’s touted by fitness professionals and wellness experts like Peter Attia as being a useful measure for all exercisers.But getting an accurate number requires an expensive and exhausting lab evaluation. And estimates provided by wearable devices might not tell you much. So how useful is it to invest time and money in the full work-up, and how important is knowing your VO2 max?For everyday people who want to be healthy and live a long time, the measurement is “the best piece of empirical information we have on health and longevity,” said Kate Baird, a clinical exercise physiologist and the coordinator of running and metabolic services at Hospital for Special Surgery in New York.The key, she said, is acting on what the data tells you.What is VO2 Max?“VO2 max” is a two-digit number that expresses how effectively your body metabolizes oxygen. The measurement itself is the milliliters of oxygen consumed in a minute per kilogram of body weight.As you exercise, your body needs ever more oxygen. The more you can efficiently consume, the more energy your muscles will have, increasing the time and intensity you can exercise. Generally speaking, someone with a higher VO2 max will be able to sustain a run or an aerobic activity at a given pace longer than someone with a lower VO2 max.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

      How 2 Families Faced a Catastrophic Birth Defect

      by

      Ashlee Wiseman, a waitress at a Sizzler in Idaho Falls, Idaho, was 10 weeks pregnant when a nurse phoned with crushing news: a test of fetal DNA in her blood had found that her baby girl had trisomy 18, a catastrophic genetic abnormality, and was unlikely to survive.Devastated, she called her partner, Clint Risenmay, who was at work. He broke down in tears.Ashlee’s response was different.“A still small voice took over me,” she said. “I’m like, ‘I’m not going to listen to them. There has to be something that can help her. And there has to be someone who can help.’”A social media search led her to Dr. John Carey, a professor emeritus of pediatrics at the University of Utah, who has devoted his life to helping families dealing with trisomy 18. He supports pregnant women who chose abortion, but also helps couples who want to have babies with this rare condition, though most will be stillborn or die within a year.Ashlee and Clint were undeterred. They could do it, they assured Dr. Carey. They would lovingly care for a baby with complex medical needs.The consequences of trisomy 18 are dire. The babies have three copies of chromosome 18 instead of two and, as a result, have serious medical and developmental problems. Nearly all are unable to eat, walk or talk, and all have severe cognitive disabilities. They often need open-heart surgery and feeding and breathing tubes. Many women, after hearing what is in store, choose abortion.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.
