We have a Canadian friend who picked up an e coli infection from eating in a restaurant while travelling in Mexico. He went to a "hospital" in La Penita where he was treated unsuccessfully under less than optimal conditions. He wound up hospitalized in Puerto Vallarta where he remained until the insurance company refused to continue to pay his medical bills. Eventually he had to fly back to Canada leaving his truck and trailer behind. Thankfully he's now on the mend.
My wife had an extremely serious asthma attack 2 weeks ago. We live 3 miles from a hospital and I doubt I could have driven her to the ER in time. Calling 911, the EMS ambulance crew had her on oxygen and in the hospital in slightly more time than it took for me to get dressed and find my car keys. She was on a sedated and on a ventilator in ICU for 3 days. One of the first things I thought of was "What if this had happened in Mexico?" It's most likely she would have been lost.
This has changed my feeling about travelling south of the border, especially by RV. We need to remember that "this ain't back home"
Glad you had a good outcome.
