1 Average daily ridership and average round trip distance used to calculate weighted average transportation cost. It includes Mass Rapid Transport and Light Rapid Transport systems, bus, and taxi. An average of two family visits per day per inpatient are assumed.

2Estimated by dividing the average cost of one student per year by number of schooling days for each year.

3Estimated using average bill size per notified dengue patient in respective institution type per year.

4Estimated by dividing the household median income by number of calendar years.

5Follows [23] by estimating ambulatory expansion factors using serological information in Singapore from 2004 onwards.

6Conservatively sets hospitalization expansion factor to 1 by assuming perfect diagnosis.
