The operation timeframe was initially three months, mainly to provide relief to persons and communities affected by the Dengue outbreak. However, the scenario has become increasingly complex due mostly to the government's additional restrictions to curtail the spread of the COVID-19 disease. Such measures have resulted in the National Society having to pause in executing some activities.

The St. Lucia Red Cross, in line with its humanitarian mandate, has revised and updated the approved plan of action to focus efforts on providing relief to the population. This proposal includes the following activities:

  • To provide 100 households with safer barrels.

  • To complete the distribution of mosquito nets and repellents to households; and

  • To conduct a lessons-learned workshop.

The St. Lucia Red Cross will extend the operation by one month. The new operation end date is 31 March 2021.
