According to MacVail, in the pre-vaccination period smallpox
was nine times as fatal as measles and seven and one half times
as fatal as whooping cough. To-day in the vaccinated community
its fatality is negligable, in the unvaccinated it is as high
as it was in the Middle Ages. In the city of Berlin, where
vaccination is absolutely compulsory, there is no smallpox
hospital at all; the cases of smallpox in that city being only
a few unvaccinated foreigners. In 1912 the deaths in New York
City were as follow: 671 from measles, 614 from scarlatina, 500
from typhoid fever, 187 from whooping cough and 2 from
smallpox.
