DIFFERENT FROM SMALL POX

In the presence of small pox in a community its differentiation from some cases of chicken pox is important but sometimes difficult. One of the most striking differences between the two diseases is that in chicken pox the lesions occur in crops, all the stages of the eruption being present at the same time, while in small pox the lesions are all the same sort at any time. Another difference consists in the distribution of the eruption, in chicken pox most is on the covered parts of the body while in small pox the eruption is most abundant on the exposed parts of the skin, the face, wrists and hands. The presence of a fairly recent vaccination scar is always strong evidence against small pox.
