Costs and consequences of large-scale vector control for malaria
 
Published on: 2008-12-17
 
Five large insecticide-treated net (ITN) programmes and two indoor
residual spraying (IRS) programmes were compared using a standardized
costing methodology.
 
Methods: Costs were measured locally or derived from existing studies
and focused on the provider perspective, but included the direct costs
of net purchases by users, and are reported in 2005 USD.
 
Effectiveness was estimated by combining programme outputs with standard
impact indicators. FindingsConventional ITNs: The cost per treated
net-year of protection ranged from USD 1.21 in Eritrea to USD 6.05 in
Senegal.
 
The cost per child death averted ranged from USD 438 to USD 2,199 when
targeting to children was successful. Long-lasting insecticidal nets
(LLIN) of five years duration: The cost per treated-net year of
protection ranged from USD 1.38 in Eritrea to USD 1.90 in Togo.
 
The cost per child death averted ranged from USD 502 to USD 692.IRS: The
costs per person-year of protection for all ages were USD 3.27 in
KwaZulu Natal and USD 3.90 in Mozambique. If only children under five
years of age were included in the denominator the cost per person-year
of protection was higher: USD 23.96 and USD 21.63.
 
As a result, the cost per child death averted was higher than for ITNs:
USD 3,933-4,357.
 
Conclusions: Both ITNs and IRS are highly cost-effective vector control
strategies.
 
Integrated ITN free distribution campaigns appeared to be the most
efficient way to rapidly increase ITN coverage. Other approaches were as
or more cost-effective, and appeared better suited to "keep-up" coverage
levels.
 
ITNs are more cost-effective than IRS for highly endemic settings,
especially if high ITN coverage can be achieved with some demographic
targeting.
