The new House of Insulation, built in the neighborhood of Parque Patricios ("Barracks Hospital"), was renamed in 1904 in memory of Francisco Javier Muñiz, an Argentine military doctor in the mid-nineteenth century, naturalist, paleontologist, Senator, and Dean of the Faculty of Medicine.

Its technical name is "Porteño Care Centre and National Reference Regional Infectious-Contagious Disease".

All infectious disease are diagnosed and treated at this hospital to include tuberculosis, pneumonia, botulism, leptospirosis, tetanus, leprosy, among others.

The hospital built a pavilion for inmates due to the high rate of infection of the AIDS virus in the national prisons.
