For better or worse, I've frequently found that government agencies will post information to Twitter well in advance (sometimes days or weeks) of updating the respective web pages. I'd edited the link in today's post to the official SESA web page, but I'm going to change it back, because the official page only shows the current day's totals. I don't see the history as the Twitter feed shows. Once I do, you can verify that the image from the feed is the same as the one in your post.
The SESA Twitter feed does indeed appear to be the official feed (joined Twitter in 2011), as does the feed from the QRoo State Police Chief. For whatever reason, they have not applied or Twitter has not deemed them worthy of being "Twitter Verified" (blue check-mark on their profile). Good for Verifacad getting the CovidMX account verified on Twitter, but in my very cursory check, I didn't see the historical data on that site, either.
While I didn't site the source, the information on the state's road restrictions came from the the QRoo state Chief of Police's Twitter feed, and I later saw the same information posted by Alerta Cozumel.
I do find -- how shall I put this -- the "communication style" of the government to be frustrating. Had I not gone to the grocery a scant two hours before the road closure debacle, we would have had some problems. When I saw the news of movement restrictions in Cozumel this weekend, I didn't immediately post it here. I did IMMEDIATELY go to the grocery, as I was trying to be good and only go once per week, and my day is (was? is?) Saturday. When the news appeared to be consistent when I returned, *then* I posted it here. But my Spanish is not yet to a level where I can get information from an original source. Even then, from I what understand, the "communication style" of the government original sources is to leave some things open to interpretation!
I'm not a professional journalist; this is hopefully a way for some of the forum members to stay connected to the island until they can return. It also gives me something to do. Somewhere in the T's & C's of ScubaBoard, I think there's something about not making any life or death decisions based on anything here. And *especially* not from any thing that I post!
