ATLANTA, Ga. – The Centers for Disease Control and Prevention (CDC) is warning parents to be on the lookout for symptoms of acute flaccid myelitis (AFM) in children.The public health agency said Tuesday that it anticipates that 2020 will be another peak year AFM, an uncommon but serious neurologic condition that affects mostly children.AFM can progress rapidly over the course of hours or days, leading to permanent paralysis and/or the life-threatening complication of respiratory failure in previously healthy patients, so it’s important to seek medical care as soon as possible.The disease has peaked every two years between August and November in the U.S. since 2014, when the nation experienced the first peak of 120 cases, according to the CDC. There were also peaks in 2016 and 2018.The third and largest peak of AFM occurred in 2018, with 238 cases in 42 states. Most cases were in children (94%) and most patients (86%) had AFM onset during August through November. Most patients had a fever and/or respiratory illness approximately six days before limb weakness onset. Other common early symptoms were difficulty walking, neck or back pain, fever, and limb pain.The CDC says parents and doctors should suspect AFM in patients with sudden limb weakness, especially during August through November. Recent respiratory illness or fever and the presence of neck or back pain or any neurologic symptom should heighten their concern.Experts say enteroviruses, particularly enterovirus-D68 (EV-D68), are likely responsible for these peaks in cases. EV-D68 is the most common virus identified among specimens collected from patients with AFM. However, other viruses can cause AFM and may also be contributing to the biennial peaks.Although AFM symptoms resemble those of polio, all specimens have tested negative for poliovirus.There is currently no specific test, proven treatment or prevention method for AFM.“As we head into these critical next months, CDC is taking necessary steps to help clinicians better recognize signs and symptoms of AFM in children,” said CDC Director Robert Redfield, M.D. “Recognition and early diagnosis are critical. CDC and public health partners have strengthened early disease detection systems, a vital step toward rapid treatment and rehabilitation for children with AFM.”AFM and COVID-19The CDC says AFM is a medical emergency and patients should seek immediate medical care, even in areas with high COVID-19 activity.It’s not known how the COVID-19 pandemic and the social distancing measures may affect the circulation of viruses that can cause AFM, or if COVID-19 will impact the health care system’s ability to promptly recognize and respond to AFM.There is one bright side. If social distancing measures decrease circulation of enteroviruses this year, AFM cases may be fewer than expected or the outbreak may be delayed.Learn more about AFM here. 2901

Australian scientists are searching for the remnants of a meteor which burned spectacularly across the sky in Perth Tuesday night.The unusual phenomenon was caught on camera by multiple spectators, and described as a "fireball" on social media.Curtin University professor Phil Bland told CNN it was "almost certainly" a chunk of asteroid coming through the atmosphere, an event which he said occurs only a couple of times a year. 437

As more and more public spaces open back up, many people are finding themselves a little jumpy when they hear someone cough nearby. Are they sick, is it allergies, is it coronavirus?Chances are, we are jumping to conclusions about those “sick” sounds we find disgusting, according to a recently published study from the University of Michigan and University of California, Irvine.“We find no evidence that perceivers can reliably detect pathogen threats from cough and sneeze sounds, even though they are reasonably certain they can,” said Nicholas Michalak, the study’s lead author and a University of Michigan psychology graduate student.In other words, we humans are not very good at distinguishing the seriousness of a cough or sniffle by the sound of it. In fact, the study found that the more disgusting a person perceived the sound to be, the more likely they were to believe the sound came from an infected person, regardless of whether it did.Previous research has indicated people can accurately diagnose infection in others using other senses, like sight and smell.The research is based on four studies that had participants judge whether a cough or sneeze sound came from people infected with a communicable (easily spread) disease or not. On average, participants guessed four out of ten sounds correctly.“Moreover, there was no evidence that accuracy improved when participants knew the true number of infectious sounds in advance or when participants focused on how clear or disgusting they perceived the sounds,” Michalak said. “Despite this poor overall accuracy, perceivers consistently reported reasonable certainty in their judgments.”The study’s authors theorized that people have a belief that a sound that disgusts them is likely to represent a disease threat - this could lead them to exhibit biases to avoid interactions with others who make disgusting but noninfectious noises, according to Mickalak.The study’s co-authors are Oliver Sng, assistant professor of psychological science at UC-Irvine, and U-M graduate student Iris Wang and U-M associate professor of psychology Joshua Ackerman.Read the full study here. 2150

As novel coronavirus cases soar across the country, states are struggling to keep up with the demand for testing. Some states are reporting big backlogs and difficulty getting tests.“We need to actually continue doing a bunch of work in America to figure out additional approaches to do testing,” said Dr. Bob Kocher.Dr. Kocher is the former co-chair of California's Testing Task Force. The state formed the team back in March to figure out how to get everyone tested. Back then, they were struggling to do 2,000 tests a day. Now, they're doing more than 100,000 a day.“California, and most states, had giant shortages of the world’s most expensive Q-tips, called swabs, that you need to collect the samples and the people who make them couldn’t make more of them,” Dr. Kocher explained. “We worked with companies to 3-D print them and to source those from other places in the world and buy them and bring them to California.”They worked to find labs that could do high-capacity testing and expanded the number of testing sites. But as cases increased across the state and nation, five months into the pandemic, testing turnaround time is an issue.“It’s something I’m concerned about as demand for testing grows everywhere in the country and on the earth, the labs are going to sporadically have backlogs, and over time, they could have backlogs because it’s hard to make more supply of the test,” Dr. Kocher said.Dr. Kocher says it depends on where the test is sent. Some labs have backlogs and it’s a logistics issue. If the lab your test site is using is in another part of the country, it'll likely take longer to get results.In a statement, Quest Diagnostics said, "We are grappling with surging demand that is outpacing capacity. This is due to surging cases of COVID-19 across much of the United States, particularly the West, Southwest and South. We have a prioritization program to help direct testing to patients most in need. Our turnaround time for priority one patients is 1 day on average."In a recent press conference, California's Health and Human Services Agency Secretary Dr. Mark Ghaly said supply chain challenges forced the state to prioritize who gets tested first.“Surges across the nation have created challenges of getting tests processed, not just collected, and ensuring our guidelines not only say who needs to be tested but give guidance to labs on which specimens to process first,” Dr. Kocher said.Right now, priority means those who are hospitalized, healthcare workers, first responders, social service employees, those who are 65 and older and those with chronic medical conditions. But, we simply need more tests.“The challenge with COVID-19 is that each person infects two, three more people and that leads to exponential growth of people who are infected and exponential growth in demand for testing,” Dr. Kocher said. “The companies who manufacture tests have been extraordinary scaling up their capacity to manufacture tests they can grow them by 10, 30 maybe a 100 percent, but the demand for COVID testing is growing 1,000 percent.”The American Clinical Laboratory Association which represents Quest and other labs released a statement saying many labs are getting more test orders than they're able to process in a single day.In a statement, the company said, "We can’t do it alone. Laboratories, diagnostic manufacturers, ordering providers, public health officials, states and importantly, the federal government – including Congress and the Administration – all have a role to play in addressing the challenges hampering our nation’s response to this public health crisis."The test, Dr. Kocher says, only tells you if you're infectious at the time you were tested. It's yet another hurdle for states to tackle."So, we need to figure out what is the mechanism to test people at the right frequency to make us all safe and fell confident in going to work, school, nursing home or being an essential worker,” he said. “It’s really important.”Figuring out what that looks like means looking at new technologies, getting the government involved and working on our manufacturing sector so we have more tests and fewer logistical problems as we consistently try to keep up with the virus that seems to be one step ahead of us all. 4276

At a rally on Sunday, President Donald Trump said that he might fire Dr. Anthony Fauci, his administration's top infectious disease expert, shortly after Tuesday's election.At a rally in Opa-Locka, Florida on Sunday, supporters broke into a "Fire Fauci!" chant as Trump discussed the COVID-19 pandemic."Don't tell anyone, but let me wait 'til a little bit after the election," Trump said.The comments marked the first time that Trump has publicly indicated that he may fire Fauci, who has been the head of the National Institute for Allergies and Infectious Diseases since 1984.Fauci, a member of the White House's corornavirus task force, has consistently been the most plain-spoken Trump administration official when speaking about the challenges the country faces amid the pandemic.Trump has publicly criticized Fauci throughout the pandemic. In October, with COVID-19 cases on the rise, Trump tweeted an attack on Fauci. Days later, during a campaign call, Trump called Fauci a "disaster" and said he and other health experts were "idiots."Polling has shown that Americans consistently believe that they trust Fauci more than Trump when it comes to handling COVID-19.In the past, Fauci has implied that the White House has limited the number of media appearances he can make, and has also said an ad by the Trump campaign took him out of context. 1358
