04 Apr 2023

Ministry of Health official reported increases in the number of malaria and dengue cases in Honiara, Malaita, Central Islands, Guadalcanal and Temotu Provinces of the Solomon Islands.

It was suggested that increased transmission may be due to the current wet season.

The official stated that mass spraying for malaria and dengue mosquitoes will be conducted in communities and also at household level.
