Introduction

Parasitic diseases are characterized by being infectious and endemic and having natural focal and other transmission features with specific pathogens, including protozoa, helminths, and arthropods. When a pathogen is excreted by a source of infection and invades a new susceptible organism, it experiences the transmission process of staying in the organism while metastasizing to the outside world. The invasion of pathogens and the influencing factors involved in this process, as well as the health resources utilized in controlling transmission, are all covered by modern disease surveillance and are the key elements in strengthening monitoring capacity and improving innovative technologies.
