During the last considerable epidemic at the turn of the century, I was a member of the Health Committee of London Borough Council, and I learned how the credit of vaccination is kept up statistically by diagnosing all the revaccinated cases (of smallpox) as pustular eczema, varioloid or what not---except smallpox.
Why is it that wellnesses are not as contagious as illnesses--generally speaking, but also especially regarding taste? Or are there epidemics of health?
