Summary of current WHO Recommendations regarding DDT and disease vector control

7.2 The use of DDT and alternatives for disease vector control

Situation analysis of the production and use of DDT for disease vector control

The selection of malaria vector control interventions should be evidence based and appropriate to the local ecology and epidemiology of the vector borne disease.

the Conference of the Parties in evaluating the continued need for DDT for disease vector control

The WHO position with respect to the use of DDT in activities aimed at disease vector control to interrupt disease transmission is as follows.

Of the responding countries, eight reported use of DDT for disease vector control for the reporting period (2001 2003).

It serves as the larval host for the nematode and acts as the vector by which the disease is spread.

Review of the information collection process for the first evaluation of the continued need for DDT for disease vector control

It fosters the involvement of principal stakeholders, especially local communities and those public sectors whose actions impact vector ecology and disease transmission.

The efficacy of DDT and its alternatives is important information for deciding the actual need for DDT for disease vector control in any local area.

According to the DDT register, three countries have notified use of DDT in disease vector control and one country notified the intention to use DDT if necessary.

In addition, there is a need to strengthen the capacity of countries in gathering and managing relevant data, including the routine reporting activities of disease vector control programmes.

The Stockholm Convention on Persistent Organic Pollutants (POPs) restricts the production and use of DDT to disease vector control in accordance with World Health Organization (WHO) recommendations and guidelines.

Conducive conditions are also created for effective regulation to minimize prevent the private sector's role in creating conditions that support vector borne disease transmission. The scope of IVM is comprehensive.

Furthermore, the system will also be used to facilitate the reporting and the evaluation processes of the Stockholm Convention regarding the use and continued need for DDT in disease vector control.

(e) Conduct of a meeting of experts to consider available information and provide a report to the Conference of the Parties on the continued need for DDT use in disease vector control

In this regard, it is recommended that a well resourced mechanism for reporting and assessment on DDT use for disease vector control, be set up under the auspices of the Secretariat and WHO.

Implication of vector resistance to insecticides

WHO SSC meeting of experts for the preparation of a report to assist the Conference of the Parties to the Stockholm Convention in its evaluation of the continued need for DDT in disease vector control

Ensure long term investments are made to encourage the development of new alternatives and to facilitate their implementation in recognition of the current need of countries to continue the use of DDT in disease vector control.

Insecticide resistance has grave implications for vector control.

This was carried out with due consideration of document UNEP POPS INC.7 INF 21 regarding the guidance and information needed to assist the Conference of Parties in evaluating continued need for DDT for disease vector control.

(iv) Collecting, compiling and generating data needed for the first meeting of the Conference of the Parties, including information necessary to review the continued need for DDT in disease vector control, evaluating the effectiveness of the Convention and

In considering the above options COP is reminded of documents INC7 4 and INC7 INF 21 regarding the guidance and information needed to assist the Conference of Parties in evaluating continued need for DDT for disease vector control.

WHO (2004) Global strategic framework for integrated vector management.

Thus, the coordinates of the stress vector formula_2 on a plane with normal unit vector formula_3 passing through a given point formula_4 is represented by formula_5And knowing that formula_3 is a unit vector we have math n_1 2 n_2 2 n_3 2 frac T_1

The Intergovernmental Panel on Climate Change has warned us that the range of vector borne diseases like malaria is likely to change thanks to climate change. Kenya has already reported cases of the disease in previously malaria free areas.

In order to ensure that the use of DDT is restricted to disease vector control, there is a need to support countries still using DDT to urgently review and improve their management practices, especially the regulatory and enforcement mechanisms.

1 It is expected that the second evaluation of the continued need for DDT in disease vector control will take place at the third meeting of the Conference of Parties in 2007 since no meeting is planned in 2008.

They are able to respond to gravity, of course, so the shoots are growing against the vector of gravity and the roots toward the vector of gravity.

(d) Field testing of the draft format for country reporting on DDT and for evaluation of the continued need for DDT for disease vector control in cooperation with the World Health Organization (WHO), including conducting an expert consultation on the latter

(c) Invite the World Health Organization to participate actively in the work referred to above and in any other manner that may support the Conference of the Parties in future evaluations of the continued need for DDT for disease vector control.

From other information available to the Secretariat and WHO, the group estimates that in total around 20 countries are still using DDT for disease vector control and five countries have indicated to WHO the likelihood to revert to it if necessary.

Mr. Francis Agyemang Yeboah, School of Medical Science, Kwame Nkrumah University of Science and Technology, Kumasi, Ghana, stressed that changes in both physical and biological factors in the ecosystem affect the distribution and abundance of disease vector organisms and intermediate hosts.

An analogy is the difference between scalar and vector arithmetic.

Rita Calwell very famously traced a very interesting story of cholera into human communities, brought there, not by a normal human vector, but by a marine vector, this copepod.

The Convention further stipulates that commencing at its first meeting, and at least every three years thereafter, the Conference of Parties (COP), in consultation with WHO, will evaluate the continued need for DDT for disease vector control (Annex B, Part II, Paragraph 6).

Countries (both Parties and non Parties) that produce and or use DDT or maintain stocks of DDT for disease vector control were requested to complete the questionnaire for the reporting period of 2001 2003 and to return it by 22 October 2004.

The Expert Group reaffirmed the urgent need for countries to develop action plans to address this issue in order to ensure that DDT use is restricted to disease vector control, as spelt out in paragraph 5(a) of Part II of Annex B.

Another major activity is the establishment of joint WHO UNEP information system to collate information from all available sources (WHO, UNEP, research institutions, countries, etc.) relevant to the production, use and management of DDT and its alternatives and policies in disease vector control.

This was a clustered SMP vector processor architecture, developed from J90 technology.
