Dengue: Dengue is a vector-borne disease transmitted by the Aedes mosquitoes. The mosquitoes carry the dengue virus and transmit it to humans through bites.

Typhoid: Typhoid is caused by the bacterium Salmonella typhi and is transmitted through contaminated food and water, not by a vector. It is not a vector-borne disease.

Chikungunya: Chikungunya is also a vector-borne disease transmitted by Aedes mosquitoes, specifically Aedes aegypti and Aedes albopictus. These mosquitoes carry the chikungunya virus and spread it through bites.

Leptospirosis: Leptospirosis is caused by the bacterium Leptospira, which is transmitted through direct contact with water or soil contaminated by the urine of infected animals (like rats). It is not a vector-borne disease.
