Seems I've missed out on a lot of discussion. Besides, I think I was in demand here. Here I am.
Hope, that was the first thing which crossed my mind. If he is suffering from dehydration, weakness etc, why check for malaria? Then read that he is shivering, has fever with chills etc. Malaria and dengue are such diseases that are suspected first and foremost when a person comes with fever- especially in a country like India. Even in our govt. hospitals, if you go with fever and shivering, first thing the doctor suspects is malaria- it is that common. Always.
And so I understand they are going according to the symptomatology.
i.e. fever with chills.
But yeah, dehydration and overexertion are not causes of his condition- they are just factors that have alleviated it to a bad extent- the body's immunity has suffered and he caught the disease (if it is indeed malaria/dengue).
Again, malaria/dengue does not develop suddenly in a minute. According to a report that I read, Sushi fainted and had to be taken to hospital. My question- when he already had fever, why was he shooting? If he fainted, it means his condition was really pathetic.Sushi boy has clearly been careless about his health. He deserved a whack from his Mom.
Hope that helps, Hope
