A study published this week takes a look at just how quickly Covid-19 test results are getting back, on average.Researchers surveyed more than 19,000 people across every state and the District of Columbia during the last two weeks of July. They asked how long people waited to get back test results.Most people, about 63 percent, are not getting their test results back within the one-to-two day window that is optimal for contact tracing.More than 30 percent of survey participants reported they received test results after four or more days.“Rapid turnaround of testing for COVID-19 infection is essential to containing the pandemic. Ideally, test results would be available the same day. Our findings indicate that the United States is not currently performing testing with nearly enough speed,” researchers said in the report of their findings.The average wait time nationwide was 4.1 days.However, there were disparities in wait times when looking at race. According to the study, Covid-19 test results wait times for Hispanics and Blacks are longer, at 4.6 days and 5 days respectively. Compared to wait times for white respondents, which was 3.9 days according to the study.Researchers said there is little sign the wait time for test results is speeding up. A similar survey conducted in April found that the national average wait time was 4.2 days.This study did not look into the causes of the delay in receiving test results. Other reporting has pointed to limited testing supplies, labs being overwhelmed with tests to run, and the time needed to contact everyone with results.On Monday, Florida’s Gov. Ron DeSantis called some Covid-19 test results “useless” because they are taking too long to come back. He announced his state is converting two testing locations to 15-minute rapid testing locations. 1823

A Pennsylvania woman is mourning the loss of her 12-year-old after claiming that the dog was mauled last week by another dog during a grooming appointment at a PetSmart, WNEP-TV reported. Betty Miller of Scranton told WNEP that after dropping off her dog named Bichon Brewster at PetSmart's grooming salon, she got a call from a veterinarian, who delivered the awful news. Brewster was killed after getting attacked by another dog.After the mauling, Brewster was taken to the Veterinary Referral and Emergency Center, but was dead on arrival. The veterinarians told WNEP that it attempted resuscitation, but failed. Now, Miller is wanting answers as to why this happened. "We called corporate," Miller told WNEP. "They did not reach out to us, and I was very angry about that. Why would you want to bring a pit bull past a small dog who's really just bait? He was bait."PetSmart responded to Miller through a statement to WNEP.  986

A swimmer died following an apparent shark attack near Bailey Island, Maine, on Monday, the Maine Department of Natural Resources confirmed.The agency said that kayakers brought the unidentified woman to shore after swimmers saw she was injured from an apparent shark attack. She was pronounced dead at the scene by EMS responders.Swimmers and boaters in the area were being told to remain cautious following the attack.The University of Florida, which has a database of shark attacks in the United States, has not reported any such attacks from 2010 through 2019 off the coast of Maine. On average, there are 45 shark attacks in the United States a year. But fatal shark attacks are very rare in the US – just seven reported fatalities in the last decade, and three in the last four years.According to the University of Florida, there was a fatal shark attack off the coast of California in May, marking the first US shark attack death in nearly two years. 965

A teacher at Dickson Intermediate School in Tennessee launched an emergency lunch money fund for students after an interaction with one child inspired her to help children in need."As I was walking through the cafeteria one day, I saw a child with no tray and no drink just stopped to build those relationships as teacher do, and just asked are you not eating? Do you need something?" said sixth grade literary teacher Julie Potter. "His comment was mom said we’re out of money so I can’t eat today."Potter told the student to grab lunch, on her.But she said she realized that was a short term solution."I thought if I could just donate just a few dollars to set up an account so the next time, the next child will feel safe enough to go through the line without worrying about pride and be fed," Potter said.So Potter put out a post on Facebook, detailing her interaction with the student and a plan to help others."I share this message to say I would like to set up a special lunch account called 1 in 4," the post read. "This account would be for those students, just a handful and only as needed, we see going without food. An account where we as school staff could quietly say, 'Go through the line and it will be taken care of.'"In just 10 days, teachers and parents have donated to the fund and two students have used the emergency money to eat.And while Dickson Intermediate never turns away a hungry student, officials said this helps further break down barriers."Some are going to feel a little embarrassed or shy about asking for help," said School Nutrition Supervisor Jason Collins. "That’s why I think it’s so important that we focus on building those relationships."According to Feed America about one in four children in Dickson County are food insecure but don't qualify for federal assistance.If you'd like to donate to Dickson Intermediate's fund you can drop money off at the school's front office or mail it to the school. Please specify that your donation is for the 1 in 4 lunch account. 2063

A multistate outbreak of listeria has been traced to a Houston manufacturer's Vietnamese ready-to-eat pork products, the US Centers for Disease Control and Prevention announced this week. Long Phung Food Products has issued a recall of its ready-to-eat pork products, which were shipped nationwide.Four people were hospitalized after eating Long Phung anchovy-marinated pork patty rolls manufactured between May 21 and November 16 and labeled with establishment number "EST. 13561." No deaths have been reported.Listeria is the third leading cause of death from food poisoning in the United States, according to the CDC, and is especially dangerous for anyone with a weakened immune system, over age 65 or pregnant. Symptoms usually occur within four weeks of infection but can take as long as 70 days to appear. In some cases, the first signs of infection are diarrhea or other gastrointestinal symptoms. Typical symptoms that follow include headache, stiff neck, fever, muscle pain, confusion, loss of balance and convulsions.Pregnant women are especially at risk. According to the CDC, they are 10 times more likely to get a listeria infection, and the odds are even higher for Hispanic pregnant women, who are 24 times more likely to get listeria.Although pregnant women typically experience only flu-like symptoms, the danger to the developing fetus is high. Infections during pregnancy can lead to miscarriage, premature delivery or stillbirth.Newborns with listeriosis can develop blood infections, meningitis and other serious and potentially life-threatening complications. Listeriosis is treated with antibiotics.The illness has affected people in Texas, Louisiana, Tennessee and Michigan, but the US Department of Agriculture's Food Safety and Inspection Service said it is concerned that families and businesses may have stored frozen products. The full list can be found on its website.The CDC advises consumers and retailers to throw away or return unused products to the place of purchase, even if they have been consumed without any sign of illness. Shelves and drawers where the pork patties were storied should be washed with warm, soapy water and sanitized. 2184
