Public Health Responses

Ongoing mosquito larvae surveillance and monitoring on Rarotonga, Aitutaki and the outer islands, as well as monitoring of adult mosquito traps at risk areas such as the hospital and airport on Rarotonga.
Continuing larvacidal application every two weeks; awareness raising; and regular reporting/update to key stakeholders and health staff.
Another clean-up campaign for Rarotonga is due, and awareness and promotion is underway this week, with inspections (Tutaka) to follow next week starting Monday the 12 of August 2019, for one week. Again the focus is to rid mosquito breeding/resting places in the community, especially around the homes and public places.
