In this summer, those sanatoriums are very busy serving their visitors.

According to Ri Myong Ho, a department director of the Ministry of Public Health, the country has more than one hundred sanatoriums, all of which are located at sites rich in mineral springs.

The sanatoriums mainly serve balneation, fangotherapy and climatic treatments. There citizens take 30-day medical treatment at state expense. If necessary, they can take 45-day treatment with the days of regular leave involved.

In recent years, a number of dwelling houses have been built around sanatoriums for convenience of patients.
