(b) When she has recovered from malaria and is taking care of someone suffering from
chickenpox.
(c) When she is on a four-day fast after recovering from malaria and is taking care of someone suffering from chickenpox. Why ?
Answer:
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 chickenpox. There are following reasons for this :
- When a person gets a disease like malaria he has loss of appetite, vomiting and high fever. This leads to loss of body fluids and makes body very weak. Under such circumstances if she is on a four day fast, then her defense system will be totally weak and she can even collapse.
- With the weak immune system if she is taking care of someone suffering from chickenpox, then it is more likely that she may also get the disease.
