Here is the Spanish version text that was sent to me - I assure you I don't have the time or interest to make this stuff up - just sharing what was shared with me and seems to go along with other reports I am getting from friends who still live on the island. And I personally know of twelve residents that have tested positive and have presented with mild to severe symptoms in 2021. Dr. Julio (one of the island's beloved veterinarians) has been hospitalized and on a ventilator for a couple of weeks now. He has improved, but still in fragile condition.
Having just been on the island, and spoken with some people who have been directly affected, I know you're being 100% honest and candid about what's going on. The person I want to share this info with has always dismissed anything about Cozumel I share from Scubaboard because he doesn't think it's trustworthy. I've explained that the info I've gotten is from people who live on the island - but like I said, he just dismisses it, saying "what would they know?". (I did find a link with the announcement - in Spanish - and he speaks passable Spanish.)
This will really impact people's visit. There will be logistical questions like 'do I need my actual vaccination card or will a picture of it be ok?'. If I'm not vaccinated, how do I prove I've had my test within the past 72 hours, and will there be a +/- number of hours leeway? Will this mean a negative test upon arrival at a resort will suffice for the entire visit, or will they want one every 72 hours while you're staying there? I guess if you leave the resort for any excursion you'll need an updated test?
This would not have been a big deal for us, but for anyone who is not vaccinated, this could be complicated. And of course, it adds to what the people in Cozumel will have to figure out while dealing with such incredible challenges already.
