In consequence of its insanitary condition, Cairo used to have a heavy death-rate.
North of the cemetery is the prison, a building which replaces a notoriously insanitary gaol used during the republican regime.
These improvements connote the obliteration of the insanitary and overcrowded courts and alleys which were to be found between all the main streets, few in number, connecting the upper and the lower towns.
This unfavourable state of affairs is due to the poverty, ignorance and insanitary habits of the lower classes.
As a consequence of these insanitary conditions the death-rate is very high, and in case of epidemics the mortality is enormous.
