Frequency of falling ill varies from person to person. It depends on personal factors such as the immunity of a person and environmental factors such as cleanliness in the surrounding in which he/she is living.

c. A person is most likely to fall sick when she is on a four day fast after recovering from malaria and is taking care of someone suffering from chicken pox.
Fasting just after the recovery from malaria would definitely weaken the immune system of the person and would not even help her to fight with any infection if she comes in contact with it. Under these conditions, if she takes care of someone who is suffering from chicken pox, she is more likely to get infected from chicken pox and will fall sick.
