An effective campaign against it, inaugurated at this time, was never abandoned until it was completely eradicated in 1906,--a noteworthy result to achieve in a country like the Philippines.
On March 21, 1902, I was advised that two patients at San Juan de Dios hospital were developing symptoms of Asiatic cholera, and on the following day a positive laboratory diagnosis was made.

Other cases followed in quick succession, and we soon found ourselves facing a virulent epidemic of this highly dangerous disease.

At the outset the mortality was practically 100 per cent.

Unfortunately, there was no one connected with the medical service of the islands who had had practical experience in dealing with cholera, and we had to get this as we went along.
At the time of the outbreak, Governor Taft was in the United States, Acting Governor Wright was in Leyte, the secretary of finance and justice was in Japan, and there were present in Manila only the secretary of public instruction and the secretary of the interior.

As the executive head of the government was absent, and there was no quorum of the legislative body, I of necessity arrogated to myself powers which I did not lawfully possess, appointing employees and incurring expenses without the usual formalities.
On the morning of March 22 I informed General Chaffee that four cases of cholera had occurred in Manila, and requested that an adequate military force be despatched to the valley of the Mariquina River to protect the city water supply from possible contamination.
This request was promptly acceded to, and the guard thereafter maintained proved adequate to prevent infection of the city water, although there are three towns on the river above the intake, and it was the custom of their people to bathe and wash their clothing in this stream.
