Smallpox
Of the 25 references for suspected smallpox and supervision of possible smallpox
contacts, 23 of these were arrivals to this country from declared endemic or locally
infected smallpox areas. They were reported to be proceeding to addresses in Islington
and were not in possession of valid international certificates of vaccination.
In accordance with the new regulations regarding international certificates of
vaccination, which came into force on 1st August, 1963, all the arrivals were visited
and kept under surveillance for the required period of time.
One of these references was from the Port of London Health Authority concerning
the s. s. "Devonia" which made an unscheduled stop at the port of Tangier for the
purpose of landing a case of non-infectious sickness. Tangier is an endemic smallpox
area, and on board the s.s. "Devonia" there was a large party of school children,
none of whom landed.
Routine surveillance was carried out in respect of two adults and 32 Islington
school children who were absent from school for any reason during the quarantine period.
Medical advice was sought for two patients suffering from rashes of a type where
it was desirable to exclude smallpox as a possible cause:-
1. A male Nigerian iged 25 years, presented himself one Sunday at a general hospital,
with a rash that had developed that morning, and the possibility of smallpox could not
be excluded. He was seen by the Deputy Medical Officer who considered the case to be
one of chicken-pJx.
A Consultant Physician on the Smallpox panel concurred with this diagnosis and
arranged for the case to be transferred to an infectious disease hospital.
2. The other patient was a male Nigerian aged 27 years, who was also found not to be
suffering from smallpox.
