Indicators at a glance: Biosecurity and border health

This section summarises the latest Environmental Health Indicators about vector-borne diseases in New Zealand, and international infectious diseases.

Summary

Vector-borne diseases are carried by mosquitos, sand flies or ticks, and can be transmitted to humans. Biosecurity reduces the risk and spread of pests and diseases, including vector-borne diseases.

Infectious diseases can also spread internationally.
