A. Malaria
B. Filariasis
C. Typhoid
D. Dengue
Solution
The mode of transmission refers to the way that the disease causes the organism to move from one place to another or one host to another. Mostly the microorganisms are transmitted by various ways like food, water, air, contact, vectors. Mosquitoes are hosts that carry germs from one place to another.
Complete Answer:
Mosquitoes are insects that carry germs with them and infect the healthy person when they bite him. Many diseases some death causes are also carried by mosquitoes. They are more present in stagnant water, rainy season, places where neatness is very less.
Malaria is caused by Plasmodium vivax that causes fever and other discomfort. It is transmitted by female Anopheles mosquitoes as they act as secondary hosts.
Filariasis is caused by Wuchereria bancrofti that is also transmitted by the female mosquito. When the mosquito bites, the infection causing agent is transmitted into the blood of a normal person.
Dengue is sometimes fatal disease which is also transmitted by mosquitoes and it is caused by a virus, causing backbone fever.
Typhoid is caused by a bacterium that is transmitted by food and water. The food that is not properly cooked or the water that is not cleaned properly contain the bacteria and cause typhoid fever.
Hence, we conclude that the disease that is not transmitted by mosquitoes is “Typhoid”. The correct answer is option C.) Typhoid
Note:
Only female mosquitoes transmit diseases as they require blood for reproduction. We need to take precautions like mosquito nets and repellants to protect ourselves from diseases and always clean water and cook food with washed ingredients and protect from diseases.
