A study of the above table shows that while Typhoid Fever las in recent years not assumed serious epidemic proportions yet the disease is always with us.
It also shows that a large proportion of the cases notified are Chinese,
It is not to be supposed that all Chinese cases of Typhoid are diagnosed as such, as it is a common habit of the Chinese to leave the Colony for their native places when sick,
Many years ago it was thought that Chinese did not suffer much from Typhoid Fever owing to their having acquired more or less immunity to the disease by reason of their so called insanitary habits.
Improved methods of diagnosis both post and ante-mortem have however shown that this disease is common amongst the Chinese in the Colony.
During the last twenty years no outbreak of Typhoid has been definitely traced to contaminated water or milk.
The eating of raw vegetables grown by Chinese methods is a possible source of infection, but the Chinese are not in the habit of eating uncooked food and Europeans soon learn the danger of eating salads.
The more probable cause of the cases is the carrier who either spreads infection by handling food or indirectly through flies which can contaminate food by carrying infective material from the buckets of the dry privies which may have been used by carrier-. It is probable that anti-typhoid innoculation would greatly lessen the incidence of this disease amongst residents in the Colony and all new arrivals who intend to reside here will be well advised to adopt this precaution.
Of the 139 cases of Typhoid which were notified in 1922, 7 Chinese and 6 Non-Chinese were imported.
DIPHTHERIA.
This is a disease which is always with us but has not when the numbers of our population are considered assumed serious epidemie proportions.
In the year under review there were notified 71 cases, 56 of which were Chinese.
There were 32 deaths all but one Chinese and, all but two were under the age of 15 years and of these 14 were between the ages of 1 and 5 years.
The table below gives the number of Diphtheria cases notified during each month of the last ten years,
The table also shows that the disease has its greater incidence
in the cooler months of the year namely October to April,
The numbers of Chinese cases each year are shown below the annual total cases.
