Entomological Surveillance
Entomological Surveillance

CARPHA recognizes that entomological surveillance in CMS is inadequate not only because of resource constraints, but also because the system of Integrated Vector Management (IVM) is archaic. The reliance of IVM on paper-based data collection and processing, especially as it relates to entomological indices and epidemiological data, cripples the effectiveness of the vector control teams in CMS. The inability to predict increases in vector populations coupled with limited knowledge of the spatial epidemiological trends, often leads to recurrent outbreaks of vector-borne arboviral diseases such as Dengue.

In response, CARPHA is attempting to modernize the data collection and processing capacities of the CMS by implementing Geographic Information Systems to the vector control programmes as follows:

Entomological Surveillance

Training and Implementation of Novel Geographic Information System (GIS) Technology for combatting vector-borne diseases.

The Epi Info for Vector Surveillance App was developed by the Centers for Disease Control and Prevention (CDC) as a Novel GIS tablet-based solution for vector surveillance and control.

In 2018, CARPHA began a regional rollout process by doing a GIS Epi-Info training workshop for 13 CMS (Anguilla, Antigua and Barbuda, Cayman Islands, Dominica, Grenada, Guyana, Jamaica, Montserrat, St. Kitts and Nevis, St. Lucia, St. Maarten, St. Vincent and Trinidad) with a total of 26 persons benefitting from the training. GIS-capable tablets were procured for all the attending CMS. The workshop was held from May 23rd to 25th, 2018 at the Insect Vector Control Division, Ministry of Health, Trinidad.

The Objectives of the workshop were:

  • 1. To strengthen CARPHA Member States’ capacity implementation of GIS technology in entomological surveillance.
  • 2. To do a follow up of the receipt, installation and use of the QGIS platform.
  • 3. To introduce vector control personnel to a novel GIS solution for entomological surveillance.
  • 4. To provide field training in the use of Epi Info App for vector surveillance.
  • 5. To demonstrate the improvement of Integrated Vector Management Systems through implementation of GIS technology.

Integrated Vector Management

The operations of several vector control programs show limited adoption of the PAHO/ WHO IVM strategies. For example, some CMS may have a decentralized vector management system, whereas others utilize the services of non-specific, cross-disciplined health control officers in the execution of activities. However, even in the decentralized system, non-health stakeholders such as agriculture or sanitation are rarely involved. There is also a lack of community involvement in the vector control operations. The CMS require expert advice in restructuring their IVM strategies to be more in line with the PAHO/WHO IVM strategies, thereby improving their ability to effectively manage, prevent and control outbreaks of emerging and re-emerging arboviral diseases.

CARPHA has responded to the IVM needs in the Caribbean through the following:
