Malaria Eradication Programme In Socotra Island

• Started in September 2000
• Main vector control measures (An culicifacies)
• Larviciding in the capital Hadibou and the
  surrounding dense populated areas
• IRHS in selected villages

7
ITNs demonstration project In Socotra Island

• January 2002 a demonstration project of
  impregnated bed nets was established in Socotra
  Island to cope with the global strategy of vector
  control
• The objective is to ensure the prevention of
  morbidity especially later during consolidation
  and maintenance phases of the eradication
  programme when larviciding will be gradually
  withdrawn.

Monitoring and Evaluation

• 1. Efficacy and impact on vector
• The insecticide susceptibility status of the
  vector
• The persistence and efficacy of insecticide on
  treated net.
• Vector biting reduction

26

• 2. Impact on malaria
• Data on morbidity and severe malaria collected
  through the existing infrastructure will be
  reviewed in order to assess the impact. School
  surveys in the operation area will be carried out
  at the end of transmission season.
• 3.Meeting with the local inhabitants to evaluate
  their usage of the impregnated nets.

27
Treated bednets contributed to malaria reduction
along with other vector control measures within
the concept of IVC
28
Current situation

• 3500 impregnated bed nets are currently
  distributed in Socotra island to replace residual
  house spraying which was carried out in the
  eastern part of the island at the beginning of
  the transmission season.
• Iconnet is used for impregnation
• it was received free of charge from a local
  private company for trial purpose.
