Hi doctor,

My father has nagging dry cough for about one month. Our physician has doubted it as allergic bronchitis and the x-ray also justifies the same. As per today, his platelet count is 125000. Is there anything to worry? Or is this a sign of dengue? Myself and my brother have just recovered from dengue. However, my father does not have a fever. Currently, he is on Nebicard 2.5 for BP, Daztor for triglyceride, Bro-Zedex and Montair LC.



Welcome to

  • For dengue, the first and the foremost thing to be present is fever. Dengue is not diagnosed only on the basis of platelet count.
  • Also, mild thrombocytopenia (low platelet) is common in older adults.
  • All you have to check is the trend of platelet count whether it is decreasing or constant over the next few days. If constant, then it is fine.
  • For cough, the treatment is fine. I suggest gargling and steam inhalation as that helps a lot.
  • Get a sputum examination done for gram stain and AFB, if he produces sputum later.

Investigations to be done:

Get platelet count done after two days and four days.

Regarding follow up:

For further doubts consult an internal medicine physician online.--->

Thank you doctor,

Is there anything to worry?



Welcome back to

  • No, there is nothing to worry. Watch the platelet trend and remember there is no possibility of dengue without fever.
  • There are many causes of thrombocytopenia. But, as his other cell counts are normal, he would not be harboring any serious disease.
  • There is no need to panic. Get the tests done and let the medication work.
