Plague.
A sharp recrudescence of plague occurred during the year, the total cases notified being 1,181.
The last previous epidemic of serious proportion occurred in 1914 when there were 2,146 cases recorded.
The incidence of this disease on the total estimated civil population of the Colony was for the year 1922, 1.78 per 1,000, but if the New Territories be excluded (except New Kowloon), the incidence becomes 2.04 per 1,000.
The following table shows the monthly prevalence of plague for the last ten years.

After a period of 47 days free from plague, a case was notified on November 14th, 1921. A severe epidemic is usually presaged by the occurrence of a few cases during the last few weeks of one year and the first few weeks of the next, even though the numbers for each week be small.
It was therefore expected early in 1922 that plague would be severe during the year.
Fortunately, the number of cases which were recorded, though high, fell short of what might have been expected.
