The correct answer is option 1, Beriberi. Beriberi is not an insect-borne disease.
Let`s analyze the other options to better understand:
Option 2, Kala azar, also known as visceral leishmaniasis, is a disease caused by the bite of infected sandflies. So, kala azar is an insect-borne disease.
Option 3, Malaria, is a mosquito-borne disease caused by the Plasmodium parasite. When an infected mosquito bites a person, it transfers the parasite into their bloodstream. Therefore, malaria is an insect-borne disease.
Option 4, Plague, is primarily spread by fleas that have bitten infected rodents, such as rats. The bacteria that cause the plague are carried by fleas and can be transferred to humans through flea bites. Hence, plague is an insect-borne disease.
In conclusion, when analyzing the options, we can see that option 1, Beriberi, is not an insect-borne disease.
