Hi! I'm so glad you posted this thread! We are getting married in Playa del Carmen and having our elderly parents with us then for our honeymoon staying in Tulum and traveling to Akumal/Coba etc. So, being that I'm in public health (I'm a trainer/educator) I decided to do some research as you did on the CDC website! You're right, it's a little contradictory but that last paragraph made me realize that we just need to really be good about the prevention measures but not have to take the malaria pills. I traveled to Guatemala back in the 90's and I was the only one in my group who decided to be cautious and take the pills. It turns out I didn't really need them as we were sticking to the tourist routes, but man those pills made me SO SICK! I was so dizzy, nauseous, and tired that it started to affect my trip, so I stopped taking them.
I think we'll be ok! Too bad we'll just be missing you in that area! We'll be coming back home the week before your wedding date.
Good luck and don't feel bad about worrying abou this! Being in public health, I've convinced myself I've had all the tropical diseases
