At least three people have died, including an alleged gunman, after gunfire erupted at a home in Port St. Lucie in southeastern Florida. Officers on scene said a chilling 911 call came in Monday afternoon, a girl said someone was inside her house shooting people.At about 1:15 p.m. ET Monday, the city’s police department advised the public to stay away from the scene on Morningside Blvd. near Morningside Elementary School. Around 3:30 p.m. ET, officers reported a man and 13-year-old girl found at the home had died. Two others found at the scene were taken to a nearby hospital. An officer was injured, and is expected to be OK. A SWAT Team then made entry into the home and found the suspected shooter dead in an upstairs bedroom. Police say it was a dispute about the alleged gunman's dog that started the incident. 830

ATLANTA (AP) — Protests quickly turned into riots in several U.S. cities over the weekend, with demonstrators squaring off against federal agents outside a courthouse in Portland, Oregon, and forcing police in Seattle to retreat into a station house. Vehicles were set ablaze Saturday night or early Sunday in California and Richmond, Virginia. And a protester who was allegedly armed with a rifle was shot and killed during an anti-police violence protest in Austin, Texas, after a witness says he approached a car that that had driven through the demonstration and the driver shot him. Authorities say someone was shot and wounded in Aurora, Colorado, after a car drove through a protest there. 704

As states across the country grapple with an increase in coronavirus cases and a huge demand for tests, many businesses are looking for other ways to get more mileage out of their supply chain.Like with anything else, supply and demand is a constant struggle. In this unprecedented era, the demand for things like coronavirus tests is so large that public health departments don't have a choice but to figure out ways to make our supplies last. Several states are examining pooled testing. California's Public Health Department says it's to "better leverage testing resources."Pooling is something that blood banks have used for decades to keep their blood supply safe. Dr. Claudia Cohn is the Chief Medical Officer of the AABB, formerly known as the American Association of Blood Banks.“If you have 100 people that need to be tested and if you test each of them, you’ll do 100 tests. If you find that your test is sensitive enough that you can pool together 20 samples at the same time, instead of having 100 tests, you can have five pools of 20,” Dr. Cohn said.Now, if one of those five pools is positive, then Dr. Cohn says, "You’ll need to break it out and test each of those separately. So, let’s say you have one positive person in a pool of 100 people, you either do 100 tests and find one positive or you do five pools of 20, four of those pools will be negative, so you’ve done 4 pools and covered 80 people."The test works by taking a tiny sample from each person who was tested.“When you take a swab from everyone’s nose, you isolate the DNA from that swab,” Dr. Cohn said about the PCR test, which is generally a nose swab. “It’s not a lot, it’s a small amount but it’s enough. Because these tests are very, very sensitive.”Those tests are so sensitive, and they have to be, that pooling can really only work if the test can handle, as in detect, multiple samples at once. The FDA mandates that.“The FDA is quite demanding as they should be in terms of making sure tests work well and are safe,” Dr. Cohn said.And Dr. Cohn says, pooling wouldn't work in an area where there's a large outbreak, which means a large number of people would test positive regardless of pooling. In the blood world, this strategy has been perfected.“You are taking 100 samples and taking a drop from each sample and putting it together,” Dr. Cohn said. “You are testing every single person who comes through. In the blood world safety is before everything."Blood banks test for HIV, Hepatitis C and B and well as COVID-19 antibodies, according to the American Red Cross. And, as this pandemic moves through our communities, Dr. Cohn says our blood supply needs to remain strong.“After that initial spike, it went down again and that was okay because elective surgery had been canceled, so the demand for blood had gone down as well so for a while we were at a good balance of demand and supply. But then elective surgeries opened up and hospitals went back to full service and we’re in a shortage again,” Dr. Cohn said. 3017

ATLANTA — Georgia Gov. Brian Kemp is suing Atlanta to block the city from enforcing its mandate to wear a mask in public and other rules related to the COVID-19 pandemic. Kemp and Georgia Attorney General Chris Carr, in a state court suit filed late Thursday, argued that Atlanta Mayor Keisha Lance Bottoms has overstepped her authority and must obey Kemp’s executive orders under state law. The suit comes a day after Kemp clarified his executive orders to expressly block Atlanta and at least 14 other local governments from requiring people to wear face coverings. Kemp’s order was met with defiance Thursday by Bottoms and other mayors, who said they would continue enforcing their mandates and were prepared to go to court.Kemp has maintained a policy of voluntary use of masks throughout the state. Georgia has seen a significant increase in COVID-19 cases in the past week. In recent days, the state is averaging about 3,000 new cases a day — by far the highest totals since the pandemic began.The CDC recommends that everyone wear a mask in public, particularly during situations where social distancing is difficult. 1133
