Abstract

The epidemic of dengue which prevailed throughout the State of Texas during the fall of 1885, was unusual in many respects, for example:

1st. In its universality.

2d. In the violence of its symptoms.

3d. In its manifest contagiousness.

4th. In the protracted convalescence of its subjects.

5th. Its hæmorrhagic tendency.

6th. In its numerous sequelæ.

From Galveston, located in the South eastern portion of the State, it spread, in the course of a few months, to its Northern border. During this time almost every city, and many of the country districts within these limits, fell under the epidemic influence of this disease. In the city of Austin about 16,000 cases of dengue occurred during this time, out of a population of 22,000 inhabitants. I am informed that other cities and sections suffered as severely, i.e., had as many cases in proportion to the population as did Austin.
