Kowloon District IV-Mongkok.
This is a small district and consequently the number of rats examined from the district is also small. The chart and table, however, present some interesting features.
It will be noticed that the period of the 40th to 47th weeks of 1903 was the one of most intense rat plague, nine infected rats being reported out of 81 examined giving a percentage of 11-1 for the whole period. Yet no human cases were recorded either during the eight previous weeks, the period itself, or during subsequent seventeen weeks.
The small epidemic endured for ten weeks only, but during this period only two rats were found infected.
