Question

(a) Summer
(b) Winter
(c) Rainy season
(d) Spring season

Answer 1

Hint: Malaria is a mosquito- borne infectious disease. It is a life-threatening disease, which is caused by the bite of an infected Anopheles mosquito. Infected mosquitoes carry the Plasmodium parasite.

Complete step by step answer:
Malaria is more common in rainy seasons as most of the mosquitoes breed in waterlogged and damp places in the rainy season. Malaria is a mosquito- borne infectious disease caused by many species of the parasitic protozoan microorganisms known as Plasmodium. Symptoms of malaria are chills, fever, and sweating, usually occurring a few weeks after being bitten. P. falciparum is the sort of malaria that's presumably to end in severe infections and if not promptly treated, may cause death.

Additional information:
The factor which can cause malaria are:
- Bitten by a malarial vector (Anopheles stephensi)
- Use of shared and infected syringes.
- Organ transplantation.
- Transfusion.
- From an infected mother to a newborn baby during birth.
The precautions to eradicate malaria are:
- Spraying insecticides to kill adult mosquitoes.
- Preventing the stagnation of water.
- Spraying light oil or kerosene on the stagnation of water to kill the larvae.
- Make use of mosquito nets to protect ourselves against mosquito nets.
- Raise larvivorous fish Gambusia in tanks, ponds, and lakes, and other water bodies.
So, the correct answer is ‘Rainy season’.

Note: A non-chemical vector control strategy includes the genetic alteration of malaria mosquitoes. Advances in gene-splicing technologies reduce the lifespan of the mosquito or create it more immune to plasmodium. Sterile insect technique is a genetic control technique whereby huge numbers of sterile male mosquitoes are reared and released.
