Mexico strives to be among the top destinations for health and wellness tourism in the world, and its close proximity and cost savings of up to and even over 50% for surgeries and medical procedures when compared to the same procedures in the US make it a popular destination indeed. It also boasts more than 100 certified hospitals by international standards of the Joint Commission International, alternative medicine such as hydrotherapy, temazcal and thalassotherapy, amongst others. This led the government and private companies to invest during the review period in hospitals and hotels in main cities such as Monterrey, Puebla, Ixtapa-Zihuatanejo, Puerto Vallarta, Queretaro, San Luis Rio Colorado, Riviera Maya, Tijuana and Mexico City. The purpose is to increase and improve infrastructure to offer high-quality services in order to attract more health and wellness tourism and increase its permanence in the country. Some of these projects are known as Health City or Medical City and include all services that patients and their families would need (accommodation, transportation and attractions, amongst others).
