How do We Know It’s Swine Flu?

This illness is not well demarcated from many other respiratory illness, like sore throat, other influenza viral sickness, tonsillitis etc.

All above mentioned conditions would have fever and pain in throat in common, making it difficult to diagnose the condition.

Diagnosing swine flu is difficult on the basis of symptoms. You get suspicious of having this illness if you have high fever and chills with any two of the following symptoms:

  • Cough, which is persistent, with or without any sputum
  • Difficulty in breathing
  • Use of extra muscles while breathing, like those of the neck, the ones between the ribs
  • Running nose
  • Pain or soreness in throat
  • Aches in different muscle groups of the body and joints. Commonly, the knee joint is affected.
  • Vomiting or watery diarrhoea
  • Headache

If you are a heart patient, an asthmatic or have any other underlying medical condition, it may get exacerbated.

      Pneumonia can take 15 to 20 days to resolve. It would depend upon the immune status of the patient, his age and nutritional status.

    I was diagnosed with influenza A yesterday. Almost 103 over the last 4 days, ibuprofen brings it down to 100-101’s but then it spikes up. I’m 65, asthmatic with a history of pneumonia x5, the last pneumonia I went septic. I’m coughing to the point that my intercostal muscles hurt like hell. The ER doc yesterday didn’t suggest a CXR; said my lungs were clear. I’m on day 5 with this virus. I would think I would have felt slightly better by now. With my history, I’m concerned about this turning into pneumonia. Thoughts on my next steps here?
