Justify the following statements:
$(a)$ "Availability of proper and sufficient food would prevent infectious diseases."
$(b)$ "The general ways of preventing infection mostly relate to preventing exposure." List three points of prevention of exposure.

(N/A) Yes, this statement is correct.
The immune system requires proper nutrition to function effectively. If an individual does not receive sufficient food and nourishment, the immune system becomes weak and cannot fight off pathogens effectively, making the person more susceptible to infectious diseases.
$(b)$ Yes, this statement is correct.
General ways to prevent exposure include:
$(i)$ For air-borne microbes, we can prevent exposure by avoiding overcrowded living conditions.
$(ii)$ For water-borne microbes, we can prevent exposure by providing safe and clean drinking water.
$(iii)$ For vector-borne diseases, we can prevent exposure by maintaining a clean environment to eliminate breeding grounds for vectors like mosquitoes.
