The CDC has recently issued guidance indicating that up to nearly one half of antibody tests are inaccurate.While early indications are that having antibodies offers some protection against reinfection, the CDC said too little is known about antibodies to determine whether it is safe for a person to no longer need to conduct social distancing. Additionally, the CDC said that a positive test should not be used at this time to determine if an individual is immune.The CDC added, “Serologic test results should not be used to make decisions about grouping persons residing in or being admitted to congregate settings, such as schools, dormitories, or correctional facilities.”The CDC said that it recommends providers use multiple antibody tests on patients, and it obtains the most accurate tests available.The CDC said that the prevalence of those testing positive for antibodies among the general population is between 5 and 25, with higher figures coming from areas with localized outbreaks. The FDA has also warned that all antibody tests can produce false results, and that “broad use of the tests, when not appropriately informed by other relevant information, such as clinical history or diagnostic test results, could identify too many false-positive individuals.” 1286

The chicken sandwich war is over. The latest fast food feud is all about mac and cheese.Just weeks after Chick-fil-A rolled out its new mac and cheese side, KFC is debuting a new mac and cheese of its own -- but not as a side dish.KFC is topping its classic mac and cheese side dish with its popcorn chicken to make a bowl of, well, cheesy chicken. Those familiar with KFC's offerings know the mac and cheese bowl is a riff off their original Famous Bowls. Rather than mashed potatoes and gravy, they're serving regular and Nashville hot sauce-coated popcorn chicken over mac and cheese.Earlier this week, Popeyes' announcement of a new chicken sandwich ignited the Great Chicken Sandwich War, which was really just fast food brands arguing on Twitter over who has the best sandwich. KFC was oddly quiet during the brawl, and this announcement may explain why.KFC isn't the only fast food chain turning its attention to mac and cheese. The mac and cheese side dish is Chick-fil-A's first new permanent side on the menu since 2017. Boston Market already chimed in with their thoughts on the dish, implying theirs is superior.KFC's mac and cheese bowls will be available on August 26. The dishes will join the chain's Fill Up menu. 1244

The number of new cases in China has dropped for a second straight day in a virus outbreak that has infected about 45,000 people and killed more than 1,100. While most of the infections have been in China, it has gradually rippled overseas. Thirty-nine new cases were confirmed on a cruise ship quarantined in Japan, bringing the total to 174 on the Diamond Princess. China is struggling to restart its economy after the annual Lunar New Year holiday was extended to try to curb the spread of the virus. Traffic remained light in Beijing and many people were still working at home.In an effort to jumpstart the economy, Chinese President Xi Jinping Tuesday promised tax cuts and other aid to industries hurt by the novel coronavirus outbreak.Xi's announcement comes as companies face increasing losses due to the closure of factories, offices, shops and other businesses in the most sweeping anti-disease measures ever imposed. The measures have disrupted travel and other industries. Some businesses are beginning to reopen but many face heavy losses. Xi said Beijing needs to “maintain stable economic operation and social harmony." 1147

The company that made billions selling the prescription painkiller OxyContin has filed for bankruptcy days after reaching a tentative settlement with many of the state and local governments suing it over the toll of opioids.The filing late Sunday night in White Plains, New York, was anticipated before and after the tentative deal, which could be worth up to billion over time, was struck.But legal battles still lie ahead for Purdue. About half the states have not signed onto the proposal. Several of them plan to object to the settlement in bankruptcy court and to continue litigation in other courts against members of the Sackler family, which owns the company.The bankruptcy means that Purdue will likely be removed from the first federal opioid trial, scheduled to start in Cleveland on Oct. 21. 819
