BREAKING—U.S. State Department has added at least 116 countries this week to its “Level Four: Do Not Travel” advisory list, putting the UK, Canada, France, Israel, Mexico, Germany and others on the list, citing a “very high level of #COVID19.” 🧵

2) On Monday, the State Department said it would boost the number of countries receiving its highest advisory rating to about 80% of countries worldwide.
Before Tuesday, the State Department listed 34 out of about 200 countries as "Do Not Travel."
3) Other countries in the "Do Not Travel" list include Finland, Egypt, Belgium, Turkey, Italy, Sweden, Switzerland and Spain. Some countries like China and Japan remain at Level 3: Reconsider Travel."
4) Washington has barred nearly all non-U.S. citizens who have recently been in most of Europe, China, Brazil, Iran and South Africa.
On Tuesday, US extended by a further 30 days restrictions in place for 13 months that bar non-essential travel at its Canadian & Mexican borders.
5) Side note - Israel 🇮🇱 being on the restricted countries is very odd. Israel is most vaccinated and has among the lowest cases now. Hmmmm. Any ideas anyone?
