hemorrhagic. The most dangerous form of smallpox is the
confluent, in which the face and arms particularly are covered
with large pustular areas of a most disfiguring appearance.

The disease called chickenpox, or varicella, has no
relationship to smallpox and does not protect from it, nor does
smallpox protect from chickenpox.

HISTORY OF SMALLPOX

There seems very little doubt that the home of smallpox was
somewhere on the continent of Africa, although it is true that
there are traditions pointing to its existence in Hindustan at
least 1000 B.C. One Hindu account alludes to an ointment for
removing the cicatrices of eruption. Africa has certainly for
long been a prolific source of it: every time a fresh batch of
slaves was brought over to the United States of America there
was a fresh outbreak of smallpox.[2] It seems that the first
outbreak in Europe in the Christian era was in the latter half
of the sixth century, when it traveled from Arabia, visiting
Egypt on the way. The earliest definite statements about it
come from Arabia and are contained in an Arabic manuscript now
in the University of Leyden, which refers to the years A.D. 570
and 571. There is a good deal of evidence that the Arabs
introduced smallpox into Egypt at the sacking of Alexandria in
A.D. 640. Pilgrims and merchants distributed it throughout
Syria and Palestine and along the north of Africa; then,
crossing the Mediterranean, they took it over to Italy. The
Moors introduced it into Spain whence, via Portugal, Navarre,
Languedoc and Guienne it was carried into western and northern
