Expert verified

a) Cholera b) Polio c) Malaria d) Obesity Answer: d) Obesity

Step by step solution

Examining Cholera

Cholera is an infectious disease caused by the bacterium Vibrio cholerae. It affects the small intestine and can lead to severe dehydration and diarrhea. Since Cholera is caused by a bacterium, it is an infectious disease.

Examining Polio

Polio, or poliomyelitis, is an infectious disease caused by the poliovirus. This virus can spread from person to person and can affect the nervous system, leading to paralysis. Since Polio is caused by a virus, it is an infectious disease.

Examining Malaria

Malaria is an infectious disease caused by a parasite called Plasmodium, which is transmitted through the bites of infected mosquitoes. The parasite multiplies in the host's liver and then infects red blood cells, causing various symptoms such as fever, headache, and chills. Since Malaria is caused by a parasite, it is an infectious disease.

Examining Obesity

Obesity is a medical condition in which excess body fat has accumulated, posing potential health risks. Obesity is not caused by a microorganism; instead, it results from various genetic, environmental, and behavioral factors, such as consuming more calories than being expended through physical activity. Since obesity is not caused by a microorganism, it is not an infectious disease.

Identifying the correct answer

Upon examining each option, we can conclude that Obesity (option d) is not an infectious disease. Therefore, the correct answer is (d) Obesity.
