(AP) — Researchers are concerned about reports from Britain and South Africa of new coronavirus strains that seem to spread more easily. Scientists say it's unclear if that's true. And for now, they don't think the new strains cause more severe COVID-19 illness or pose any concern for vaccines. Viruses naturally evolve as they move through the population. One strain recently detected in England has a lot of changes to the spiky protein that's targeted by current vaccines. The advice to the public remains the same — wear a mask, wash hands often, and keep social distance to avoid catching and spreading the virus. 627

"The Marjory Stoneman Douglas shooting was a horrible tragedy and it is devastating to think that the loss of innocent lives of students and faculty could have been prevented. As a mother, I cannot imagine the heartbreak and pain the families of the victims and the whole Parkland community have felt every day since February 14, 2018. I want to thank the Florida Department of Law Enforcement and the Broward State Attorney's Office for investigating this tragedy and holding Scot Peterson responsible for his inaction." 529

YOKOHAMA, Japan. – The Centers for Disease Control (CDC) announced Tuesday that travel restrictions have been placed on all remaining passengers and crew of the Diamond Princess, the cruise ship quarantined off the coast of Japan because of a COVID-19 outbreak on board. Under the restrictions, the more than 100 United States citizens still on board the ship or in Japanese hospitals will be prevented from returning to the U.S. for at least 14 days after leaving the Diamond Princess. The restrictions apply to the ship’s other passengers and crew as well. “After disembarkation from the Diamond Princess, these passengers and crew will be required to wait 14 days without having symptoms or a positive coronavirus test result before they are permitted to board flights to the United States,” said the CDC in a press release. If an individual from the cruise arrives in the U.S. before the 14-day period ends, the CDC says they will still be subject to a mandatory quarantine until they have completed the 14-day period with no symptoms or positive coronavirus test results.The CDC says there may be additional confirmed cases of COVID-19 among the remaining passengers on board the Diamond Princess, because of their high-risk exposure.The CDC says these travel restrictions have been put in place to protect the health of the American people. “We continue to believe that the risk of exposure to COVID-19 to the general public in the United States is currently low,” wrote the CDC. “The U.S. Government is taking these measures to protect the Diamond Princess passengers and crew, their loved ones, the traveling public, and communities within the United States.”Sunday night, two charter flights carrying Diamond Princess passengers landed at military bases in California and Texas, starting the clock on another 14-day quarantine period to ensure passengers don’t have the new virus. A total of 14 of those passengers were confirmed to have contracted COVID-19. 1980
