Solution:
A condition in which a person is most likely to fall sick when she is on a four-day fasting as soon as she has recovered from malaria and is taking care of someone suffering from chicken-pox. Because she has not completely recovered from malaria and she is fasting when her immune system is still weak. At this stage her body will not be able to fight against infection and if she is taking care of someone else suffering from chicken pox even she can get infected with chickenpox virus and will fall sick again.
