§ 101. Varioloid.
This is a modification of small-pox. The eruptive fever is milder than in small-pox, and the suppurative fever is generally wanting; the pustules appear in the same order as in small-pox, are frequently very numerous and confluent, sometimes filled only with lymph or quite empty, the scurfs are not as thick and hard as those of the real small-pox, and the skin is not disfigured, but exhibits for a time an efflorescent appearance. There are cases, however, where varioloid is as violent and dangerous as small-pox.
The treatment is the same as that of small-pox.
