There are more than 153,000 hospital beds, 121,000 physicians and 37,000 dentists (ratios comparable to developed nations). The relatively high access to medical care has historically resulted in mortality patterns and trends similar to developed nations': from 1953 to 2005, deaths from cardiovascular disease increased from 20% to 23% of the total, those from tumors from 14% to 20%, respiratory problems from 7% to 14%, digestive maladies (non-infectious) from 7% to 11%, strokes a steady 7%, injuries, 6%, and infectious diseases, 4%. Causes related to senility led to many of the rest. Infant deaths have fallen from 19% of all deaths in 1953 to 3% in 2005.
