There are many questions and few answers after President Donald Trump announced that he and first lady Melania Trump have tested positive for the coronavirus.One thing is for sure: The ripple effects from Trump’s diagnosis are extensive.The president said he and the first lady will isolate following their confirmed positive coronavirus test. That means Trump’s visit to Florida on Friday for a scheduled Make America Great Again rally is off. He was also scheduled for a roundtable with supporters in Washington on Friday. That is now canceled.Only one event now remains on Trump’s schedule for Friday: A phone call on COVID-19 support to vulnerable seniorsAlso, senior Trump aide Hope Hicks is isolating at home after she is confirmed to have the virus. It is unclear if other staffers who were in contact with Hicks and the president have also come down with the virus. Both Trump and Hicks were seen on Wednesday in Marine One in close contact with other staffers including Jared Kushner.With a now confirmed outbreak of the coronavirus inside the White House, a number of senior staffers, Secret Service agents, aides and others may be required to quarantine. How the White House will function with a president in isolation and senior staff in quarantine remains in question.But the president’s physician showed optimism that Trump can continue his duties as president.Dr. Sean Conley said, "Rest assured, I expect the President to continue carrying out his duties without disruption while recovering and I will keep you updated on any future developments."The CDC says that for those with confirmed coronavirus cases, isolation is necessary for 10 to 20 days.“For most persons with COVID-19 illness, isolation and precautions can generally be discontinued 10 days after symptom onset and resolution of fever for at least 24 hours, without the use of fever-reducing medications, and with improvement of other symptoms,” the CDC said. “A limited number of persons with severe illness may produce replication-competent virus beyond 10 days that may warrant extending duration of isolation and precautions for up to 20 days after symptom onset; consider consultation with infection control experts.”There are also questions on how this impacts Joe Biden’s campaign. Biden shared a stage with Trump on Tuesday, and senior staff of both candidates sat in the audience for Tuesday’s debate.Also, questions on what role Vice President Mike Pence will be forced to play in the coming weeks is in question. 2511

This week, experts are sending warnings to those considering seeing people outside their household without quarantining first. One aerosol expert weighs in on just how dangerous the holiday could be."My simplest advice is it is not a good idea to meet with people outside of your household for a holiday meal. That’s the most important message that can be underscored, and the reason for that is there are multiple ways this virus can be transferred,” said Alex Huffman, an aerosol expert and associate professor at the University of Denver. “The closer you are increases the chances of that, but aerosols can come out of your mouth and mix into the room. The longer you're in that room, the more chance you have of getting sick.”Huffman says time, ventilation and proximity have a big impact on whether coronavirus droplets can spread and infect others."When you breathe and talk, the louder you talk, droplets and aerosols come out of your mouth. So, traditionally, droplets are on the bigger side, aerosols are on the smaller side," said Huffman.With no mask on, these droplets can land on the faces of people around you or on their plates."And so, the biggest danger with the Thanksgiving meal or holiday meal or any meal specifically, restaurants included, are that you have to take off your mask to eat and that is why eating together indoors is so dangerous," said Huffman.Huffman demonstrated how fast droplets can spread in the air by showing how quickly food coloring can spread in water. He also analyzed the risks of eating a Thanksgiving meal in person, taking commonly-used models and applying varying factors that come into play when eating with people outside of your household."And then, I used the same model to say, ‘What happens if we meet for holiday meals?’ Let's say we have 10 people. We all eat for two hours. We all don't have masks on, and then, we ran different scenarios. If it was a small room, a large room, a medium-sized room and then estimate the amount of risk that would be from aerosol," said Huffman.Matching with community transmission rates, Huffman estimated that the probability of each person at the table having COVID-19 was about 5 percent."If it's a small room, everybody has something like a 15 percent chance of getting infected, even if we had no idea if anybody was infected or not. If it's a big room, it's a little bit less than that," explained Huffman.Ventilation also comes into play, which is why experts are advising that if you really are planning to meet with family this holiday, do it outside. Opening windows and doors also helps. Huffman also has some tools people can use, such as a carbon dioxide monitor or you can create your own box fan air filter."On the back, this is a furnace filter that’s also 20 inches and so you tape them together so they're well-sealed. You turn it on high and you blow the air through this filter and that removes the particles in the room that could potentially contain virus in it," said Huffman.Still, Huffman and other medical experts agree this won't completely eliminate the risk of spreading COVID-19. The safest thing to do is stay home and avoid celebrating Thanksgiving with people who are not part of your household. 3230

They call it "The Game." But one of the fiercest rivalry college football games will have to wait a few more weeks due to the massive Camp Fire burning in Northern California. Due to the poor air quality in the Bay Area from the Camp Fire, Saturday's Stanford/California football game has been postponed until Dec. 1. The game will take place one day after the Pac 12 championship game, but both teams have already been eliminated from contention. As of Friday, the Camp Fire has killed at least 63, and hundreds are missing. The game, which was going to be held on California's Berkley campus, is just one of many college sporting events being postponed this weekend due to poor air quality. "We have been carefully tracking air quality in Berkeley and the Bay Area over the past week, relying on the best data and guidance available to us from medical and environmental experts," California's Athletic Director Knowlton said. "The forecasts we have received show a minimal chance of the improvement necessary to hold the game on Saturday. While we would have preferred to play the Big Game on its scheduled date, once we realized that air quality would likely not return to acceptable levels, we made the decision to postpone for the health and safety of our student-athletes, coaches, gameday staff, students, band and spirit groups, alumni and fans."Berkley is located roughly 150 miles from Paradise, which was the epicenter of the Camp Fire.  1481

Those looking to make a smaller carbon footprint when they eat out or order food have a new option. Panera announced this week they will label items on their menu that have a low impact on the climate as “Cool Food Meals.”Panera is partnering with the World Resources Institute to identify climate-friendly entrees, with a low impact on the climate. The company says about 55 percent of their entrees have the “Cool Food Meal” designation.“At Panera, we are passionate about keeping the customer at the heart of everything we do, and that includes giving our guests choices to lower their impact on climate change through the food they eat in our bakery-cafes,” said Niren Chaudhary, Chief Executive Officer, Panera Bread in a press release. “Understanding the impact of what we eat on the environment is one way we can all take a small step toward combating climate change.”The World Resources Institute says they recommend Americans try for 3.59 kg CO2e at breakfast, and about 5.38 kg CO2e for lunch or dinner.These benchmarks represent a roughly 38 percent decrease from current averages, which will help the country meet environmental standards established in the Paris Agreement on climate change.In general, plant-based foods have a lower impact on the environment than meat or daily products. However, it’s also about moderation.The WRI looks at entree ingredients to determine its carbon footprint accounting for emissions during the agricultural supply chains and land used to produce the meal.Some of the items that get the new designation include Panera’s broccoli cheddar soup, Fuji apple chicken salad, and Mediterranean bowl.Roughly 25 percent of greenhouse gas emissions are from agriculture and related deforestation, according to WRI. 1760
