Control of Disease Vectors in Ports: The purpose is to control vector density (i.e., any infectious disease carrier such as rats or mosquitoes) at ports to prevent the spread of communicable diseases. Taiwan CDC has taken the following measures to eliminate the breeding of vectors.
- Placing anticoagulant bait year-round where rats are most active. The bait is replenished every 10 to 15 days to ensure its efficacy.
- Monitoring the parasites and infectious serum of rats in port areas. Captured rats are examined for parasites and blood serum is tested for Rickettsia typhi, plague and hantavirus.
- Eliminating Breeding Sites of Dengue Fever Vectors: Empty containers that are prone to retain water (bottles, jars, tires, etc.) and check monthly to track the breeding of vector mosquitoes.
- Setting Ovitraps: Cloth traps moistened with temephos are placed around ports/airports for mosquitoes to lay eggs. After the eggs hatch, the larvae are killed with insecticide. The traps are replaced monthly, and the number of eggs laid is used for calculating the mosquito index in the port areas.
- Surveying Mosquitoes: Lamps are hung in the selected places for trapping mosquitoes to identify species and track their activities.
