As health experts warn about rising coronavirus cases from spread at indoor gatherings, a new website backed by recent research is trying to help people understand just how many people in what size space is risky for infection. Which could come in handy as some people consider small holiday gatherings.It’s more risky to be in a small room compared to a large gym. If people are calm and quiet, it is safer than singing or exercising no matter how distant they are.Given these types of scenarios, and the “rapidly advancing science” of how COVID-19 droplets behave, scientists at the Massachusetts Institute of Technology created the COVID-19 Indoor Safety Guideline application.Here’s an example:An average suburban house that is 2,000 square feet, with 25 people inside wearing cotton masks and talking in a whisper, can reduce their risk of transmission by only staying inside for 4 hours.If those same 25 people, in the same house, are not wearing a mask and are talking normally, the length of time to reduce transmission drops to just 50 minutes.And if those 25 people, in the same house, are singing along to Christmas music, without masks on, that time to safely reduce COVID-19 transmission indoors drops even further to just 8 minutes.If the size of the gathering is only 5 people, and there is still singing, no mask wearing, and it’s still a 2,000 square foot house, it becomes unsafe after just 27 minutes.The MIT website offers users the ability to select room size, number of people and length of time, then using previous research and scientific knowledge of airborne viruses, it predicts the risk of the indoor event. Users can change elements of the situation, like room size, mask wearing, ventilation, etc.Click here to visit the Indoor Safety Guideline website.In a restaurant, to reduce transmission, 50 people without masks and talking normally should stay for only two hours. If the restaurant has 100 people, to reduce transmission risk, they should only remain inside for 64 minutes.The researchers note current general social distancing guidelines (remain 6 feet apart) suggest 138 people would reduce their risk in the same size of space for an indefinite amount of time.Another example, a Boeing 737, the researchers’ model predicts 100 people can be onboard a 737 wearing masks and still reduce their risk of transmission by staying onboard less than 6 hours.The CDC updated their guidance about COVID-19 this fall, acknowledging ongoing research that shows coronavirus droplets “can remain suspended for many minutes to hours (in the air) and travel far from the source on air currents.”The Centers for Disease Control and Prevention also says coronavirus droplets can remain even when an infected person has left the room and can travel farther than six feet. 2800

An outbreak of salmonella infections linked to chicken salad has sickened 65 people in five states, the US Centers for Disease Control and Prevention reported Thursday. No deaths have been reported, but 28 people have been hospitalized.Diarrhea, fever and abdominal cramps are the symptoms of salmonella poisoning. Signs of illness usually occur within 12 to 72 hours and last for four to seven days in most cases.An investigation by the CDC and the US Department of Agriculture linked the outbreak to chicken salad produced by Triple T Specialty Meats Inc. in January and February and sold at Fareway grocery stores in Illinois, Iowa, Minnesota, Nebraska and South Dakota. Most of the sick people are in Iowa.Triple T Specialty Meats has recalled all chicken salad sold at Fareway stores between January 4 and February 9.If consumers purchased chicken salad from Fareway but don't remember the date, they should not eat it, the CDC says. Either throw it away or return it to the store.Even if some of the chicken salad was eaten or served with no ill effects, the CDC advises throwing the rest away in a sealed bag so children or animals cannot eat it. Wash and sanitize countertops, refrigerators or freezers -- wherever the salad was stored.Because foods from animals may be contaminated with salmonella, never eat raw or undercooked eggs, poultry or meat, the CDC says.Most people recover from a salmonella infection without treatment. However, for some, the diarrhea may be so severe that hospitalization is necessary. In rare cases, an infection can lead to death unless a patient receives prompt treatment with antibiotics. 1648

As a massive caravan of migrants treks north, US officials have been negotiating with Mexico about how to handle the caravan should it reach the US border.Officials are weighing the legality of certain steps the Trump administration could take and looking at whether any processes could be changed to speed up the removal of migrants who have no legal basis to remain in the US, according to a senior Department of Homeland Security official.The official says the administration hasn't made any "firm decisions" about how to respond if the caravan reaches the border.Among the topics being discussed with Mexico is whether migrants from the caravan could be held there before entering an official port of entry, the DHS official said. The official said this is already being done to some extent, and described this as a more official process of what is known as "metering," when Customs and Border Protection officers keep immigrants in Mexico to limit the flow into the US. This process has been sharply criticized by advocates, who accuse officials of illegally trying to block immigrants from claiming asylum.A spokesperson for Customs and Border Protection referred all questions on the caravan to DHS.Additionally, the US is negotiating with Mexico about whether migrants from the caravan could be deported there, regardless of their country of origin. This process, known as "return to territory," which was included in President Donald Trump's January 2017 executive order on border security, isn't currently carried out by Immigration and Customs Enforcement, because Mexico would need to agree to take foreign nationals back."A lot of these (options) depend on cooperation and discussions with Mexico," the official said.There were 401 claims for asylum from the caravan that made its way to the US last spring, with 374 of those receiving "credible fear referrals," which is the initial screening to ensure a claim could have merit, according to Citizenship and Immigration Services data.ICE has been talking with contractors to discuss the possible need for additional detention capacity, according to the DHS official. ICE is also preparing for the possibility that it might need more officers at the border, the official said, stressing that while officials are preparing for various possibilities, they have not taken action.DHS has not responded to a request for comment on these policy considerations, but on Tuesday, DHS spokesperson Tyler Houlton tweeted that "stopping the caravan is not just about national security or preventing crime, it is also about national sovereignty and the rule of law. Those who seek to come to America must do so the right and legal way."On Tuesday, another senior administration official said the "administration wants the ability to return whole entire Central American families and also minors after apprehension."This official called the asylum system the "world's largest immigration loophole.""You simply come up to the border, you make a totally fraudulent assertion and it puts you into a legal system that takes more time to play out than we can detain you for, and so it becomes a ticket to catch and release," said the official on Tuesday. 3211

AMES, N.Y. -- In the tiny village of Ames, New York, new homeowners unearthed a secret history that sounds too far-fetched for reality.Nick Drummond and Patrick Bakker are the owners of the Bootlegger Bungalow. They have been living in the rural home for about a year. They were told it was built by a bootlegger, but they didn’t believe it until their recent renovation brought out the truth.“I was in the process of removing this rotted wood skirting that went around the mudroom sort of where the foundation would be if it was a truly finished structure, and as I’m peeling back the boards on one of the sides, all of the sudden all this hay falls out and I was very confused," Drummond said. "And at first I was like ‘oh this must be insulation’ – of course all this is taking place within a few seconds in my head – and then I look and I’m like ‘well wait a second, what’s that glass thing?'""And then I pull it up and I’m looking at this old liquor bottle, and then I’m looking at the other package and there’s these other little tops poking out of the hay, and then I look back at the wall and there’s like the edge of this other package tied up with string and I’m like ‘holy crap, this is like a stash of booze,’” Drummond said.Sixty-six bottles of Gaelic whisky from the prohibition era were hidden for nearly a century within the walls and floorboards of a little shack tacked onto the side of the house, originally used as a mudroom to store coats and shoes.“It was like you found the jackpot," Bakker said. "Like this is what you always want to find in a house.”The bootlegger who lived there was Count Adolf Humpfner. According to newspapers of the time, he was the talk of the town and involved in a lot of scandal. Drummond says he died a sudden mysterious death, leaving all the bootlegger alcohol behind.“I mean, the guy had a buffalo robe," Drummond said. "I don’t even know what that was. But I’m just imagining this tall, heavy set German guy walking around in a buffalo robe surrounded by dozens of cash registers. Ya know it’s fantastic, I love it, I love thinking about that.”As they continue renovating the house, Drummond and Bakker say they want to preserve its incredible history.“Every building has a story to tell," Drummond said. "And it’s really a matter of peeling back all the different parts and pieces and sort of analyzing them. And you’d be surprised by what you can find.”Keeping only a couple damaged bottles, they say they plan to sell the rest to collectors, each one worth something between and ,200.“At the end of the day, we’re just sitting and we’re like ‘we really like the house so much more now,'” Bakker said. 2672
