In ferrets, nasal drops seem to prevent COVID infection

New York Times: Nasal Spray Prevents Ferret Covid Infection, Studies Find

A nasal spray that blocks the absorption of the SARS-CoV-2 virus completely protected the ferret it was tested on, according to a small study published Thursday by an international team of scientists. This study, limited to animals and not yet peer-reviewed, was evaluated by several health professionals at the request of the New York Times. If the spray, which scientists have described as non-toxic and stable, proves to work in humans, it may offer a new way to combat pandemics. The daily splits on the nose act like a vaccine.

New York Times: Children Produce Weaker Coronavirus Antibodies, Study Results

A new study published Thursday suggests that children infected with the coronavirus have fewer antibodies and their types that are weaker than adults and resolve the infection much faster. Other studies suggest that the overly strong immune response may be due to people who have become severely ill or died of Covid-19. A child’s weak immune response, paradoxically, may indicate that the virus defeats the virus before it causes havoc in the body, a severe coronavirus-induced disease, Covid. It can help explain why the child is mostly immune to the symptoms. It may also indicate why the virus is unlikely to spread to others. (Mandabili, 11/5)

Philadelphia Inquirer: Llama “Nanobodies” May Bring COVID-19 Treatment, Pitt Scientist Says

Can Rama’s Wally hold the key to COVID-19? The immune system of black-coated animals living on farms in Massachusetts was induced to produce “nanobodies” (small antibody cousins) that neutralize coronavirus in laboratory experiments, the University of Pittsburgh said. Scientists reported Thursday. Powerful proteins are still being tested in other animals to measure their ability to prevent COVID-19, and Pitt’s research team has a solid time frame for when they could be tested in humans. I didn’t. (Avril, 11/5)

NPR: blood clots, stroke, rash. Is COVID-19 a vascular disease?

With the widespread destruction of COVID-19, whether it’s a strange rash on the toes or a blood clot in the brain, researchers are increasingly focusing on how the new coronavirus interferes with blood vessels in the body. As scientists become more familiar with the disease, they will focus on the vasculature, a network of more than 60,000 miles of arteries, veins, and capillaries in the body to understand and control the widespread disease. I found a cure that I can do. The most harmful effect. (Stone, 11/5)

The Washington Post: Loss of odor from Covid can distort odors and taste

Jennifer Spicer thought the days of feeling the influence of covid-19 were over. The fever, chills, and severe malaise that restored her body in July had long disappeared. And her sense of smell and taste slowly returned to the excitement of the self-proclaimed “foodie.” “I thought I had recovered,” said Spicer, 35, an infectious disease specialist at Emory University School of Medicine in Atlanta, who was exposed to the new coronavirus through the patient. Her senses weren’t completely restored, but she was eating and drinking “completely normal” again. “I felt a lot of relief,” she said. But that relief lasted only until Friday night in late October, when she drank a sip of freshly poured red wine. “It tasted like gasoline,” Spicer said. (Chu, 11/5)

NBC News: Covid-19 Can Exacerbate People’s Tinnitus

29-year-old Rebecca Edgar has a hard time hearing her talk to her toddler from the backseat of the car. Most nights she struggled to fall asleep and was involved in a cycle of worry that her tinnitus might grow, recognizing that this stress exacerbated her symptoms. “Tinnitus has been constant for the past two decades, and it’s arguably the worst tinnitus ever,” said Edgar of Essex County, southeastern England. “I’m very scared because I’m deaf in one ear and catching Covid-19 can destroy the rest of my hearing.” (Sullivan, 11/5)

ABC News: Working in the office rather than remotely can double the risk of COVID: CDC

Employees in the office are more likely to be infected with the new coronavirus if they commute to work on a regular basis rather than working from home, according to a new report. According to a study released Thursday, public health investigators investigating the potential exposure of employed adults to COVID-19 found that workers who were positive for COVID-19 were negative. We found that we were almost twice as likely to report that we were commuting to work on a regular basis compared to our employees. As part of the Centers for Disease Control and Prevention’s weekly morbidity and mortality reports. (Schumaker, 11/5)
