Oh God no - they have something that if you work you have access to the social hospital but from what I see and hear, treatment is bare - like when you break your wrist you won't get world class guy putting you back together with pins and screws. An instructor from Aldora broke her wrist in a silly scooter accident - Aldora has a great relationship with International (private) Hospital and I remember it was a few days and Memo intervening before she was seen by the correct people - if that had been the social hospital.......Mexico doesn't have universal health care?
There is another lower level of care for the non employeed, I'm not even sure what they do.
The private hospitals, that is where you need to get to if you have a problem. It is an island of limited size, so in reality, rapid treatment doesn't always happen but the Dr's in the private area are really really good, you just need to pay or have recognized insurance.
