Net mapping project

Net mapping project CORE Group Fall
meeting October 7, 2009
The Net mapping project was prepared by John
Milliner, USAID/AFR, PMI Team, at the request of
the Alliance for Malaria Prevention
2
LLINs

• Long Lasting Insecticide treated bednets
• Proven intervention for malaria control
• Integral part of many malaria programs in Africa
• World Bank
• Global Fund
• UNICEF
• PMI
• among others

3
Universal Coverage
Covering everyone in Africa at risk to malaria
with a LLIN by December 30, 2010
4
Net mapping project

• This project was developed to address several key
  questions for the malaria community
• How many LLINs are currently in Africa?
• Where are they?
• When were they delivered?
• What nets are worn out or are in need of
  replacement?
• How many?
• Where are they?
• When do they need to be replaced?
• How close are we to Universal Coverage?
• How many more nets do we need?

5
Net mapping project
We are now in a position to answer these
questions.

Net mapping project

• Project designed as a top down approach
• Builds on manufacturer deliveries
• Limited number of manufacturers
• Incentives established to encourage
  participation
• confidentiality
• win win data sharing

7
Net mapping project

• Assumptions on data collected from
• manufacturers
• Manufacturer deliveries by country is a true
  reflection of the number of LLINs in sub-Saharan
  Africa
• Sumitomo, A-Z, Vestergaard-Frandsen, Clarke,
  BASF, Intection/BestNet, Tana Netting, are the
  only manufacturers of LLINs and no other LLINs
  are available in sub-Saharan Africa
• All nets delivered to a country were distributed
  in that country with very little cross border
  movement

8
Net mapping project

• Assumptions on net replacement
• Life of a net
• Polyester nets last 3 years
• Polyethylene nets last 4 years
• Very little agreement on this issue

9
Net mapping project

• Assumptions on population and universal coverage
• Malaria at-risk population estimates in 2010 by
  country were obtained from Bob Snow, et al from
  their work on the MAP project
• Universal coverage defined as 1 LLIN per 2
  persons at-risk
• Adjustments for other interventions such as IRS
  or ITNs

10
Net mapping project

• Methodology
• Determine the number of LLINs currently in each
  country using manufacturer delivery data
• Determine the number of LLINs already worn out
  and in need of replacement based on type of net
  and when they were delivered
• Determine the number of LLINs needed to reach
  universal coverage based on malaria at-risk
  population
• Calculate the number of new LLINs needed to reach
  universal coverage based on
• Requirements for new nets need available
  replacements

• Results for sub-Saharan Africa

• Map 1 Progression of LLIN deliveries 2004 2008
  in Africa
• Map 2 -Cumulative LLINs for 2004-2008 period in
  Africa
• -Progress toward universal coverage

Net mapping project
As of June 30, 2009 the number of available LLINs
in sub-Saharan Africa represents 52 of the total
required for Universal Coverage
23
Net mapping project
As of June 30, 2009, we will need 232M new LLINs
in sub-Saharan Africa to reach Universal Coverage
by December 30, 2010
24
Net mapping project

• Conclusions to date
• This project has developed a methodology to help
  establish a base of knowledge on nets.
• We now know
• How many nets are in sub-Saharan Africa
• Where they are
• When they were delivered
• When do they need to be replaced
• How many more nets we need
• Where we need them

25
Net Mapping Project

• Conclusions for the Core Group
• Global focus to get these nets to the countries
• Huge need for effective local distribution
• Community-based NGOs can have a significant role
• BCC is also necessary for effective utilization
