As health officials around the world tack COVID-19 infection rates, two universities in the U.S. have partnered with Facebook to try to predict infections with real-time survey data.Dr. Alex Reinhart, an assistant teaching professor of statistics and data science at Carnegie Mellon University and a member of the Delphi Group, says that as health officials were struggling with testing capacity in the spring, they realized they might be able to predict infections by analyzing social media."They realized that if we could know when people are experiencing symptoms, they probably experience symptoms a few days before seeing a doctor. That's probably a few days before they get test results back and so that could potentially be an early indicator," Reinhart said.The Delphi Group reached out to Facebook, which agreed to help them survey its users."Every day Facebook takes a random sample of their active users that day in the United States and internationally and invites them through a little blurb at the top of their newsfeed that says, 'you can help coronavirus research' if you take this survey, which is voluntary," Reinhart said.Once Facebook users click on the survey button, it takes them to Carnegie Mellon's page for the survey. The University of Maryland also jumped on board with the project and conducted the survey for all international Facebook users.Facebook does not receive any survey data and only refers to the interested participants to the survey links. So far, more than 30 million people have taken the survey.Dr. Frauke Kreuter, who is working with the University of Maryland in Germany on the international side, says she's not aware of another global survey on COVID-19."There are two factors globally, I would say. One, is that many countries do not have good reporting systems and so they rely even more on alternative data sources. And the other one is, you want to compare yourself to other countries, but for that you need to have kind of the same measure in each country," Kreuter said. "And that's what we're lacking with a lot of measures right now because each country does there reporting slightly different."So far, Carnegie Mellon and the University of Maryland have been able to develop heat maps showing coronavirus symptoms across the country and world. Reinhart says they've been on par with COVID-19 infection rates being reported from health officials and says the survey has helped them identify patterns when it comes to mask-wearing and infection rates."In early September, we started asking questions about mask usage and we soon found that there is a striking difference in mask usage across the country," Reinhart said. "At the time, places that had lower mask usage seemed to be having a worse time in the pandemic."Reinhart says the survey results are helping them learn more about the effects of mask mandates. Researchers are hoping to continue the survey as the pandemic evolves — for example, they hope to begin gauging users on vaccine usage and skepticism in the coming months.The data is available for anyone to view and use."It's different from what you can get from cell phone mobility data that we see people use because we get to directly ask people what they're thinking, how they're feeling, what they're experiencing," Rinehart said. "We'd like as many people as possible to discover this data and use it for their own important research questions." 3430

An autopsy has confirmed a man who died after a medical emergency mid-flight last week had COVID-19 and it likely caused his death.The 69-year-old man, identified by the coroner as Isais Hernandez, and his wife were on a United Airlines flight from Orlando to Los Angeles on December 14 when he had a medical emergency. The plane made an emergency landing in New Orleans, and Hernandez later died.The coroner for Jefferson Parish, Louisiana, says Hernandez’s cause of death was “acute respiratory failure, COVID-19,” according to the New York Times.A man trained as an EMT was onboard and began CPR and life-saving measures along with other passengers and flight attendants when Hernandez fell ill.Tony Adalpa tweeted later that he had COVID-19 symptoms after helping Hernandez, and overheard his wife tell paramedics Hernandez had COVID-19 symptoms, including the loss of taste and smell.Adalpa had originally planned on getting the COVID-19 vaccine this week. Instead, he’s waiting for a second coronavirus test result.When the plane landed, United believed the man’s emergency was cardiac arrest, and they allowed passengers to “take a later flight or continue on with their travel plans,” the airline told NBC News.The airline says they were later contacted by the CDC and “are sharing requested information with the agency so they can work with local health officials to conduct outreach to any customer the CDC believes may be at risk for possible exposure or infection," a representative for the airline told CBS LA.United says Hernandez had filled out a questionnaire before boarding the flight, which asked about testing positive for COVID-19 and having symptoms. It is now apparent the man "wrongly acknowledged this requirement,” the airline said.A United spokesperson told the New York Times that as of Tuesday, no other passengers or crew members have tested positive for COVID-19 since the December 14 flight. 1931

As hospitals are becoming overwhelmed with COVID-19 patients, North Dakota is permitting coronavirus-positive health care workers to continue assisting patients.The guidance stipulates that the health care workers must remain asymptomatic and take enhanced precautions in order to stay on the job. This comes as travel nurses are stretched thin as dozens of states are reporting record hospitalizations.Given the situation in North Dakota and elsewhere, it is possible more states will have to follow suit and continue using infected staff members in order to provide care. The CDC has spelled out guidance in these situations.The CDC says hospitals must exhaust a number of other guidelines, including adding travel nurses, postponing elective medical procedures, and postpone elective time off, before going into a crisis staffing situation.“If shortages continue despite other mitigation strategies, consider implementing criteria to allow HCP (health care personnel) with suspected or confirmed COVID-19 who are well enough and willing to work but have not met all Return to Work Criteria to work,” the CDC’s guidance states. “If HCP are allowed to work before meeting all criteria, they should be restricted from contact with severely immunocompromised patients (e.g., transplant, hematology-oncology) and facilities should consider prioritizing their duties in the following order:1. If not already done, allow HCP with suspected or confirmed COVID-19 to perform job duties where they do not interact with others (e.g., patients or other HCP), such as in telemedicine services.2. Allow HCP with confirmed COVID-19 to provide direct care only for patients with confirmed COVID-19, preferably in a cohort setting.3. Allow HCP with confirmed COVID-19 to provide direct care for patients with suspected COVID-19.4. As a last resort, allow HCP with confirmed COVID-19 to provide direct care for patients without suspected or confirmed COVID-19.”North Dakota Gov. Doug Burgum spelled out the challenges facing his state.“Our hospitals are under enormous pressure now,” Burgum said. “We can see the future two, three weeks out, and we know that we have severe constraints.”Despite Burgum’s warning, his state is among the ones not to issue an order requiring masks in public places.In update CDC guidance, the agency says that masks can reduce the viral load for the wearer, in addition to prevent the spread of the virus.Steven Weiser, MD, president of Altru Health System in Grand Forks, North Dakota,, wrote in an op-ed about the toll the virus is having on workers. "Your neighbors in healthcare are pleading with you – they are tired, they are covering shifts for their colleagues who cannot work, they are working in new areas and rallying together to ensure that our promise of providing care to our community is upheld," Weiser wrote. "I ask you, on behalf of our team of healthcare workers, to please take the recommendations... very seriously. This is about protecting our at-risk community members and friends. We need your partnership to stop the spread, now. Doing so will save lives." 3105

ARCADIA (CNS) - Horse-racing fans and animal advocates calling for a ban on the sport were expected at Santa Anita Park Saturday for the biggest day of the park's racing calendar, with the million Santa Anita Derby headlining a 7-race schedule amid an ongoing controversy over a recent spike in horse deaths at the famed track.The Santa Anita Derby plays a major role in determining the favorites for next month's Kentucky Derby.Twenty-three horses have died at Santa Anita since Dec. 26, but two- time Triple Crown-winning trainer Bob Baffert told reporters last week that he remains confident about the level of safety at Santa Anita."If I thought there was a danger out there, I wouldn't even (send) my horses out there so I'm feeling good about what's going on here. But I don't want to jinx myself," said Baffert, who noted that he hasn't had any issues with his horses at the track since the racing season began Dec. 26.RELATED: Horse suffers fatal injuries at Santa Anita track, marking 22nd death since December"We've been under this dark cloud so hopefully we can move forward," he said.Baffert is expected to have two of his top 3-year-old colts -- Game Winner and Roadster -- in the Santa Anita Derby.A small group of protesters was already at the track Saturday, hours before the scheduled first post at noon.Heather Wilson told KTLA5, "We are here because we are speaking up for the horses that don't want to be here. They're not given a choice: They are forced to perform, and they are forced to race. There's nothing normal, there's nothing natural about horse racing, and we are actually calling for it to end."As for future races at Santa Anita, the California Horse Racing Board will hold a special meeting Friday to discuss "possible reallocation of race dates granted to the Los Angeles Turf Club at Santa Anita Park Race Track."Such a move, however, would require approval of The Stronach Group (Santa Anita's parent group) and Tim Ritvo, COO of The Stronach Group, told Daily Racing Forum that Santa Anita fully intends to maintain its schedule of racing through the end of the current meet, June 23.Santa Anita had been closed to racing for most of March in response to the deaths. Racing resumed March 29, one day after the California Horse Racing Board approved restrictions on certain medications administered to the animals. Two days later, the 23rd horse death occurred when 5-year-old Arms Runner stumbled during the Grade 3 San Simeon Stakes on a hillside turf course that requires horses to briefly cross over the main dirt track.On Tuesday, Ritvo said the track will suspend races on the hillside turf course to "look at data" in the aftermath of Arms Runner's death.Also Tuesday, Sen. Dianne Feinstein, D-California, sent a letter to the CHRB urging it to suspend all racing at Santa Anita "until the cause or causes of these deaths can be fully investigated.""I also ask for more information about what the California Horse Racing Board is doing to both investigate this matter and address some of the concerns that these incidents have rightly raised," Feinstein wrote.The CHRB recently approved proposals to strictly limit the use of anti- inflammatory medications on horses. It also approved a much-discussed 50 percent reduction in the allowable amount of Lasix, a diuretic that helps prevent horses from hemorrhaging. Santa Anita officials had initially proposed a ban on Lasix, but struck a compromise with the Thoroughbred Owners of California and the California Thoroughbred Trainers calling for a 50 percent reduction in allowable dosage.Santa Anita officials previously announced a series of other measures being implemented to help bolster safety of the horses, including:Phasing out the use of whips by jockeys;Complete transparency of all veterinary records;Trainers must apply for permission to work a horse (a timed, high- speed training exercise) at least 48 hours in advance;No therapeutic medications of treatments will be allowed without a qualified veterinary diagnosis from a state licensed veterinarian;Significant and strict out-of-competition testing;Increasing the time required for horses to be on-site prior to a race; andA substantial investment by The Stronach Group in diagnostic equipment to aid in the early detection of pre-existing conditions.Between December and February of the previous year, 10 horses died at Santa Anita, compared with eight in 2016-17 and 14 in 2015-16. The track averaged about 50 deaths per year from 2008-18, according to data from the CHRB.The unusually large amount of rain that has fallen over the Southland last winter has been mentioned as a possible factor in explaining the surge in deaths.Former track superintendent Dennis Moore and Mick Peterson of Racing Services Testing Lab were brought in to conduct a thorough analysis of the main track, and officials repeatedly said they found no problems.Saturday's races also include the 0,000 Santa Anita Handicap. 4974
