Vector-borne diseases - World Health Organization (WHO)
2024年9月26日 · Vectors are living organisms that can transmit infectious pathogens between humans, or from animals to humans. Many of these vectors are bloodsucking insects which ingest disease-producing microorganisms during a blood meal from an infected host (human or animal) and later transmit it into a new host, after the pathogen has replicated.
Disease vector - Wikipedia
In epidemiology, a disease vector is any living [1] agent that carries and transmits an infectious pathogen such as a parasite or microbe, to another living organism. [2][3] Agents regarded as vectors are mostly blood-sucking insects such as mosquitoes.
