The Centers for Disease Control and Prevention updated its international covid-19 travel advisory system Monday, designating its highest-risk category for extreme scenarios. As of Monday, the CDC dropped all countries from its “Level 4” category, now labeled “Special Circumstances/Do Not Travel.” About 120 destinations now have a Level 3 advisory — including Australia, the United Kingdom, Italy and many other popular European destinations — for “high” levels of the coronavirus, while 12 destinations sit at Level 2. Another 55 are designated Level 1, its lowest-risk level. (Diller, 4/18)

A global analysis of nearly 6 million COVID-19 deaths over 2 years reveals that 6% more occurred on weekends than on weekdays in all countries except Germany, according to data to be presented at the annual congress of the European Society of Clinical Microbiology and Infectious Diseases (ESCMID) Apr 23 to 26 in Portugal. ... The study authors said the higher weekend death rate may have been due to lower hospital efficiency, uneven staffing levels, a different mix of personnel expertise, variable hours, reduced capacity, or delays in reporting.

More than 80 countries have put restrictions on imports of U.S. poultry products out of fear of bird flu spreading from American farms to their shores. During the bird flu outbreak of 2014-2015, roughly half as many countries barred U.S. poultry. But those bans applied to any American poultry. This time, more nuanced trade policies parse their import restrictions to poultry from specific counties or regions in the U.S. where a highly contagious form of bird flu has been detected. “There is a large reduction in the size of restricted zones from past outbreaks,” Mike Stepien, a spokesman for the U.S. Department of Agriculture’s Animal and Plant Health Inspection Service, wrote in an email to Harvest Public Media. “Previously, several countries restricted the entire United States, and many countries implemented state-wide restrictions.” (Peikes, 4/18)
