The author adds that owing to the fact that the city possesses many large and modern
hospitals, which are greatly resorted to by patients from the interior, many of the deaths
from malaria shown as occurring in Rio de Janeiro are of cases that did not contract their
infection in the city.

440. Panama.-Since the commencement of work at Panama there has been an
extraordinary reduction both in the total amount of sickness and mortality, and that recorded
from malaria. Gorgas describing the present conditions, says :
"Our death-rate for the total population on the Zone has fallen from a
maximum of 67.72 per 1,000 in July 1906 to 21.52 in December 1909. The rate
for 1905 was 49.94 ; 1906-48.37 ; 1907-33.63 ; 1908-24.83; 1909-18.19 (per
thousand). The death-rate among employees from disease has fallen from a
maximum of 62.15 in July 1906 to 10.13 in December 1909."
