Top health officials are considering “pooled testing” as a way to ramp up COVID-19 tests.Here's how it works:Instead of testing each sample individually, labs pool together a certain amount, like 10, in one tube with one test.If it's negative, you double check it, and then you're done.If there's a positive, you break it down either into smaller pools or individually for further testing.“So, there are advantages, mostly cost savings, that's the huge advantage of pooling, also the ability to go through a very large volume of specimens,” said Dr. Thomas Quinn, an infectious disease researcher at National Institute of Allergy and Infectious DiseasesQuinn worked in one of many labs that used the pooling technique during the HIV epidemic in the 1980s. He says the difference between then and now is the tests themselves.Pooling dilutes the samples. The HIV tests were very accurate, so that wasn't an issue, but with COVID-19, the tests aren't as reliable.The other problem is pooling takes more time in the lab, even with robotic equipment helping.“We need to get everyone tested and everyone wants to know what's the result of my test within 24 hours. That's very hard to do with pooling,” said Quinn.Quinn isn't recommending pooling for individual testing right now. He says it could be more useful in big surveys, when it's not an emergency. 1357

Toby the cat has been on quite the adventure in recent weeks.After his owners near Raleigh, North Carolina decided to drop off Toby at a friend's home, Toby left to return to his previous owners, who lived 12 miles away, according to the SPCA of Wake County, North Carolina. Instead of taking Toby back in after his 12-mile trek, the family instead took him to a shelter and requested the staff euthanize the cat. He was then transferred to the SPCA, which is a no-kill shelter.Toby is a healthy 7-year-old feline who has enough energy to walk 12 miles.On the SPCA’s Facebook page, dozens of commenters criticized the owners’ actions, with some offering to adopt Toby.On Monday, the SPCA announced that Toby had found a permanent home.“He has three new siblings (one feline and two human) and a cat-savvy mom to show him what a loving family is really like,” the shelter said on its Facebook page. 920

TIJUANA, Mexico. (KGTV) -- Migrants in Tijuana took shelter from the rain Thursday beneath tarps and in tents as shelters remained overcrowded. Photos taken by 10News show makeshift camps where migrants hid in tents while others shielded themselves with tarps as rain drenched the area. Many of the migrants waiting to claim asylum say they’ve lost hope following a clash Sunday in which hundreds of migrants rushed the border in a show of force. PHOTOS: Migrants in Tijuana take shelter from the rainMeanwhile, Mexico’s President-elect Andres Manuel Lopez Obrador’s government signaled earlier this week that it may be willing to house migrants while they apply for U.S. citizenship. Mexico’s new foreign minister is also putting pressure on the Trump administration to contribute to development projects that would help create jobs in Central America.

There have now been more than 2 million confirmed cases of the novel coronavirus in the United States, according to a database kept by Johns Hopkins University.The U.S. surpassed the milestone early Thursday morning. More than 112,000 people have died in connection with the virus in the United States — all of them coming since February.Across the country, many regions are seeing a gradual increase in cases as states ease lockdown restrictions. Earlier this week, 14 states reported 7-day highs associated in newly-reported cases. Some of those see increases have occurred in rural areas of the country.More than 7.25 million people worldwide have contracted the disease since it was first detected in China late last year. The U.S. continues to lead all countries in confirmed cases, followed by Brazil (about 740,000 cases), Russia (about 493,000 cases) and the United Kingdom (about 290,000 cases).The U.S.also leads all countries in deaths linked to the virus, followed by the U.K. (about 41,000), Brazil (about 38,000) and Italy (about 34,000).Health experts suspect that the true number of people who have been infected with the coronavirus is likely much higher. Many people often experience mild symptoms and never seek out a test. Some countries, like the U.S., were also limited by a lack of testing resources at the beginning of the outbreak.Though there is currently no cure or vaccine for the coronavirus, Dr. Anthony Fauci of the National Institute for Allergies and Infectious Diseases says he hopes the NIH will have a "couple hundred million" doses of a viable vaccine available by the end of the year. 1630
