Is my son having 'swine' flu?

' Is my son having 'swine' flu?"
Father of a young IT professional who is admitted under my care was asking. He was admitted for fever and cough.He had just come back from a Metro City where there were many cases of Novel H1N1 Influenza A infections.
How can I answer him?
He is sick for 2 days,but not very sick.None of his colleagues or room mates were sick.There is nothing to suspect a severe infection. But can I be sure it is not H1N1 flu?
No, unless I have got a negative test result.
To do the test for this patient I will have to send him to nearby Govt Hospital.The doctor there had informed me that the result is delayed by at least 5 days. By that time the patient would have recovered fully or may be in a critical condition.
Then what is the use of sending for the test?
What should I tell this worried Parent?
I explained that as of now I do not suspect H1N1 flu. I also told him about the delay in getting the result. I said I am confident that he will recover fast.
I hope the patient recovers fast and my dilemmas in diagnosis will soon be over.
