As we shield ourselves in any way possible from the novel coronavirus, there are some parts of the country handling social distancing better than others.“This is a public health problem; it’s not a private health problem,” explained Dr. Bhaskar Chakravorti, who leads the Fletcher Institute for Business at Tufts University. “If I get sick, I could make three other people sick.”Over the past few months, Dr. Chakravorti and his colleagues have been analyzing mobility data from across the country.What did he and his team discover?The top three states who were practicing social distancing the most were New York, New Jersey and Massachusetts. Nebraska, South Dakota, Arizona were among the worst when it came to practicing social-distancing procedures. Dr. Chakravorti says that has led to higher contagion rates in those areas.“In this post-pandemic moment, each state is going in somewhat a different direction as far as how it's managing the pandemic,” he added.In bigger cities with higher rates of infections, the study found that people responded better to restrictions because they could see the impact the coronavirus was having around them. Dr. Chakravorti hopes public health officials use his findings to make more uniform policies nationwide.“This whole issue of COVID has become a political issue, so even the act of wearing a mask has become a political statement,” he said. “You never want to mix politics with anything. You definitely don’t want to mix it with public health. That’s a dangerous combination.” 1534

Hopkins had previously accused fellow USPS employees of changing the date of ballots submitted after the election. 501

  

Authorities in India have decided to hold off retrieving the body of the American national feared killed on North Sentinel Island amid concerns about a possible confrontation with the tribe that lives there.John Allen Chau is believed to have been killed by Sentinelese tribespeople after he visited their island home in the Andaman and Nicobar archipelago in November, breaching local laws strictly prohibiting contact with the isolated people.Indian police say Chau found local fishermen who agreed to take him near the island, before using a canoe the rest of the way. Days later, the fishermen -- who have since been arrested for facilitating his trip -- say they saw the tribespeople dragging his body around the island."We want to avoid direct confrontation with the tribespeople," Dependra Pathak, director general of police of the Andaman and Nicobar islands, told CNN when asked about the latest efforts to retrieve Chau's body. "We do not want to go there and create an unhappy situation."The decision to avoid a direct confrontation with the isolated tribe came after a series of meetings and reconnaissance trips made by the officials. Anthropologists and tribal experts were also consulted.By Sunday, authorities had mapped out the area with the help of the fishermen and observed several members of the tribe walking around the area where eyewitnesses claim to have seen Chau's body dragged and buried.However, despite ruling out any immediate attempts to land on the island, local police would not categorically rule out retrieving the body at a future date. "We are working on it. We'll firm up a plan very soon," said Pathak. 1660

  

BALTIMORE - Food safety experts are warning parents to be mindful when packing perishables like sandwiches and yogurts in your child's lunch.Tanya Brown with the United States Department of Agriculture (USDA) said you're looking at a two-hour window before those brown bag lunches become breeding grounds for bacteria.“You should not put perishable items like bologna sandwiches, turkey sandwiches, cheese or yogurt in a brown paper bag and send a child to school with it,” Brown said.Foods can hit the "danger zone," or temperatures between 40-140 degrees Fahrenheit, when it’s left out of refrigeration over two hours. After four hours, the food item should be tossed.“You want to make sure you put them in an insulated lunch bag with at least two cold sources and those two cold sources could be a frozen water bottle or frozen juice packs or gel packs in there. So, you want to put those perishable items in there and make sure the child does not open the bag and keep opening and closing the bag before lunchtime,” said Brown.If you're sending them with something hot, use a thermos, and warm it up first.“The best way to prepare it is to pour boiling hot water into the thermos first, then discard the hot water and then put the hot soup or stew in there. Make sure it's at 165 degrees Fahrenheit,” Brown said.However, the leading cause of sickness is poor hand washing. Brown said this is an easy problem to solve:“Oftentimes, children don't get an opportunity to wash their hands before they go to lunch and just to trigger their memory put a moist toilette in there or some hand sanitizer to remind them before they start to eat their lunch,” she said.Click here for more information on the danger zone and safe handling of food. 1751
