Table 3

Dengue outbreak response: activities and limitations.

Key component of vector control activities*Extent to which activities were undertaken in Nepal in 2010Reasons for problems identified and how to improve

Entomological surveillanceLimited—few surveys were undertaken in 2006 and one in 2010 at the beginning of the outbreak, only 122 houses included in one municipality.Due to poor human resource capacity, only two entomologists in Nepal.

Routine search and destroy of vector habitats campaignNot in place. No routine vector control.Dengue new and emerging, not previously seen as a threat. Coordination poor in 2010.

Emergency search and destroy of vector habitats campaignWell run programme through community mobilisation, particularly in Chitwan and Rupandehi. Community received programme well. Not in all vulnerable areas.Expand programmes to more vulnerable areas.

Awareness campaignThorough programme run by district public health office and good role of the media.
Not enough IEC materials and reactive rather than anticipatory.
Need to ensure that awareness campaign is started earlier, before rainy season. Plans to include schoolchildren in future campaigns.

Water treatment by insecticideNot done in Nepal.Insecticides not available.

Insecticide treated netsNot utilised in Nepal. Some nontreated nets available through malaria programme.Funds not available.

Fogging (insecticide spraying in public areas from vehicles)Undertaken in some districts in Nepal. Repeated several times as high public demand.Contentious issue over effectiveness. Educate community over low effectiveness. Need advice from other organisations to maximise effectiveness.

Water container coversWidespread use in Nepal, part of search and destroy and education campaign.

Improvement of water supply and sanitationNot done in Nepal. Poor coordination with district office and WASH cluster.

Interagency coordination
“Multisectoral Dengue Action Committee” setup
Poor. No NGO/INGO collaboration. Poor link and slow communication between central and periphery.
Meetings held with central level and municipality, little evidence of further multisectoral action.
More municipality meetings planned.

IEC: information, education, communication; WASH cluster: water, sanitation, and hygiene sector; NGO/INGO: nongovernmental organisation/international nongovernmental organization.
