Feasibility of ultra‐low‐volume indoor space spraying for dengue control in Southern Thailand
To assess the feasibility of conducting standard indoor space spraying using ultra‐low‐volume (SID‐ULV) in terms of willingness to pay (WTP) and ability to pay (ATP) and ability to conduct space spraying by local administrative organisations (LAO) in lower Southern Thailand.
Cross‐sectional study. The executive leaders of each LAO were asked to state their WTP and ATP for SID‐ULV. Willingness to pay was measured by the payment card and open‐ended question methods. Ability to pay was calculated using the budget allocation for space spraying and estimated expenditure for SID‐ULV. Ability to conduct the SID‐ULV was assessed by interviewing the spraymen. Average WTP and ATP were calculated and uncertainties were estimated using a bootstrapping technique.
Ninty‐three percent of executive leaders were willing to pay for SID‐ULV. The average WTP per case was USD 259 (95% confidence interval [CI] 217–303). Thirty‐eight percent of all LAO had actual ATP and 60% had ideal ATP. The average annual budget allocated for space spraying was USD 2327 (95% CI: 1654–3138). The amount of money LAO were willing to pay did not vary significantly between their different types, but ATP did. Thirty‐two percent of spraymen could not complete all nine procedures of SID‐ULV.
Although WTP for SID‐ULV space spraying was high, ATP was low, which revealed the flexibility of budget allocation for SID‐ULV in each LAO. The spraymen require training in SID‐ULV space spraying.
