Biosecurity

This section is about health effects related to biosecurity and border health. 

Vector-borne diseases are carried by mosquitoes, sandflies 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. Border health protection aims to limit and respond to the international spread of infectious diseases.
