उत्तर
are vectors for many diseases
Explanation:
Vectors are living organisms that transmit infectious diseases from animals to humans or from humans to humans, without themselves being affected by the disease. Mosquitoes are the blood-sucking insects that ingest disease-producing microorganisms during a blood meal from an infected host (human or animal) and later inject it into a new host during their subsequent blood meal. Mosquitoes are the vectors for a large number of diseases such as dengue, malaria, filariasis, brain fever, chikungunya, yellow fever, etc.
