WHO Review of chemicals for aircraft disinsection

WHO is undertaking a re-evaluation of chemicals currently used and proposed for use in aircraft disinsection. This aims to assist Member States to implement the International Health Regulations (2005), Annex 5, Specific Measures for Vector-Borne Diseases, which states that where there are methods and materials advised by WHO for disinsection, these should be employed (Annex 5, clause 2) and that States should accept disinsection if methods and materials advised by WHO have been employed (Annex 5, clause 3).

The importance of aircraft disinsection for disease vector control is described in the Bulletin of the World Health Organization.

The current WHO publication on aircraft disinsection dates from 1995. An update regarding the use of pyrethroids in aircraft disinsection has also been published. The advice in these documents is adopted by many countries.

The first stage of this project includes the development of a generic risk assessment model, which is now available for public review.

In parallel, WHO is developing guidelines for efficacy testing of insecticide products for aircraft disinsection. The development of these guidelines is being co-ordinated by the World Health Organization Pesticide Evaluation Scheme (WHOPES).

Once the risk assessment model has been finalized, the next stage of the project will involve the collection and assessment of information on products used and proposed to be used for aircraft disinsection.

WHO would like to invite interested stakeholders who may wish to send information on products to be assessed as part of this project to indicate their interest to IPCSMAIL, and they will be kept informed of developments, timelines etc.
