Small pox — Vaccination. 
Because of the high percentage of vaccinated 
individuals in the community small pox is not a common 
disease. 
Occasionally an outbreak occurs in a community 
which has escaped vaccination and a small epidemic 
results. Usually such outbreaks are confined to out- 
lying Malay villages where checking of vaccinations is 
difficult. Energetic action under the Quarantine and 
Prevention of Disease Enactment eliminates the 
disease. 
Typhus and scarlet fever are unknown in Malaya. 
Enteric. 
Enteric fever cannot be said to be prevalent. In 
the Straits the death rate last year was 0.12 per mille, 
in the Federated Malay States it was 0.02. The reason 
for the low figures is probably the purity of the water 
supplies and the comparative absence of flies. 
Measles and Chicken Pox. 
These diseases are not rare but usually the cases 
are mild and the mortality rate low. 
Cerebro-spinal Meningitis, 
From time to time isolated cases occur but never 
has it reached anything like epidemic form. 
Leprosy. 
The number of lepers in Malaya is not known 
but there are 790 isolated in the Straits Settlements 
and about 550 in the Federated Malay States. 
The island of Pulau Jerejak near Penang is' a 
leper settlement which caters for cases from the Straits 
Settlements and the Malay States.
