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

As America awaits a vaccine for the coronavirus, doctors are encouraging the public to obtain a flu vaccination. While there is hope that social distancing measures in place due to the coronavirus will influence a less severe flu season, public health experts are stressing flu vaccinations in an effort to reduce the burden on medical facilities nationwide.When should you get one?Flu vaccines are generally widely available now, but some public health experts say waiting until October might not be a bad idea.Generally, the flu peaks from December into March. There is a fine balance between getting a vaccine too early and too late, experts say. One concern about getting a vaccine too early is the effects of a vaccine could wear off before the end of flu season.“I usually recommend people get an influenza vaccine in October because we want to make sure that the vaccine lasts for the full duration of the season,” said Dr. Amesh A. Adalja, a senior scholar at the Johns Hopkins Center for Health Security. “However, if a person can only get a vaccine in September or maybe after October, it is important just to get it whenever they can.”Likewise, the CDC’s official guidance says that flu vaccines are recommended by the end of October. The agency says that getting a vaccine in July or August “is likely to be associated with reduced protection against flu infection later in the flu season, particularly among older adults.” The CDC agrees, however, that there is benefit in getting a vaccine as late as January for those who fail to obtain one before the start of the season.Where to get a vaccine?While many doctor’s offices offer flu vaccines, perhaps the easiest place for most Americans is while they’re shopping.Major retail chains such as Target, CVS and Kroger offer vaccines.At CVS and Target, customers can book a vaccination appointment by texting “FLU” to 287898. Target and CVS also accepts walk-in appointments. CVS, which also operates pharmacies at Target stores, says that vaccines are generally free with most insurance providers. The cost for those without coverage ranges from .99 to .CVS said it expects to administer 18 million vaccines to Americans this flu season. CVS also said that it is taking proper precautions to administer the vaccine to customers amid the coronavirus pandemic.“We have reduced the number of touchpoints in the process and implemented new guidelines in accordance with the CDC,” a CVS spokesperson said in a statement. “For example, patients will be given a COVID-19 screening questionnaire and have their temperature taken prior to any immunization. They must also wear a face covering or mask (one will be provided, if needed). The pharmacist or MinuteClinic provider administering the immunization will also use personal protection equipment (PPE), including plastic face shields and will utilize enhanced cleaning protocols between patients.”Kroger said it is also accepting appointments for flu vaccines. For those not wanting to go into a store, Kroger is offering drive thru vaccines, akin to the drive thru coronavirus testing sites. Also at Kroger, flu vaccines are generally free with most insurance providers."With so many health facilities already overburdened due to the COVID-19 pandemic, it is more important than ever for all Americans to get a flu shot," said Colleen Lindholz, president of Kroger Health. "At our COVID-19 drive-thru test sites, we were able to assist thousands of people in getting a test in a short amount of time. By using that model to provide flu shots, we hope to provide more customers with a safe, convenient option to get vaccinated."Who should get a vaccine?Vaccines are recommended for most Americans over the age of 6 months. The CDC said that people with severe, life-threatening allergies to flu vaccine or any ingredient in the vaccine should talk to a doctor before obtaining a vaccine.For those ages 2 through 49 who are not pregnant, a nasal flu vaccine is an option.While a flu vaccine does not prevent all infections, last year’s flu vaccine was estimated to prevent 4.4 million illnesses, 2.3 million medical visits, 58,000 hospitalizations, and 3,500 deaths, according to CDC data. 4210

An alligator was spotted trying to climb the fence at Lely High School in Naples, Florida, Monday morning.Ray Simonsen, a.k.a "Ray the Trapper," was called in to get it.“Gators can climb. That’s why you can find them wherever, whenever," said Simonsen.Simonsen said he wasn’t surprised by what the gator was doing, but by how big it was.“I received a call that there was a 4-foot gator on property. I roll up and I get a big grin on my face, because that 4-foot was 7-foot 6-and-a-half-inch," said Simonsen.But that alligator Simonsen caught wasn’t the only one that got somewhere it didn’t belong on Monday. According to the Lee County Sheriff’s Office, deputies had to respond to the Estero Parc Apartments, because an alligator actually got inside the building.The sheriff’s office posted a picture to Facebook, saying people were in the elevator when the doors opened, and a small gator was there to greet them. 923
