Question

Matching pair of vector and disease is
A. Sandfly-Plague
B. Culex-Filariasis/Elephantiasis
C. Body Louse-Typhoid
D. Housefly-Yellow fever

Answer 1

Hint: A disease that results from an infection transmitted by blood-feeding arthropods, such as mosquitoes , ticks, and fleas, to humans and other animals. Dengue fever, West Nile Virus, Lyme disease, and malaria are examples of vector-borne illnesses.

Complete Answer:
- For any species or genus of flying, biting, blood-sucking dipteran (fly) found in sandy areas, sandfly (or sand fly) is a colloquial term.In North Africa, cutaneous leishmaniasis, a sandfly-transmitted disease; Leishmania infantum = green, Leishmania major = blue, Leishmania tropica = red;
- Various sandflies spread leishmaniasis, a disease caused by many members of the genus Leishmania.
- Culex is a mosquito genus, most members of which are vectors of one or more big bird, human, and other animal diseases. The diseases they carry are arbovirus infections, such as West Nile virus, Japanese encephalitis, or St. Louis encephalitis, filariasis and avian malaria.
- A hematophagic ectoparasite louse is a body louse (Pediculus humanus humanus, also referred to as Pediculus humanus corporis) that infests humans. This is one of three lice of this kind, the other two being the head louse and the pubic louse.The cutaneous disease Pediculosis corporis, marked by severe itching, may be caused by body lice.
- The housefly (Musca domestica) is a fly of the Cyclorrhapha suborder. Houseflies are a pest that disturbs individuals at leisure and at work, but they are despised mainly because of their food contamination habits. They alternate with feeding on human foods between breeding and feeding in dirty areas, during which process they soften the food with saliva and deposit their faeces, posing a health risk.

Thus the correct answer is option (B) Culex-Filariasis/Elephantiasis.

Note: About 17% of all infectious diseases are caused by vector-borne diseases, causing more than 700,000 deaths annually. Either parasites, bacteria or viruses may cause them.
