Symptoms of H1N1 flu


Swine Flu is threatening us again in India with another outbreak. Check the swine flu symptoms here if you are in doubt.

If you or a member of your family has a fever or high temperature (over 38°C/100.4°F) and two or more of the following symptoms, you may have H1N1 flu:

  • unusual tiredness 
  • headache
  • runny nose
  • sore throat
  • shortness of breath or cough
  • loss of appetite 
  • aching muscles
  • diarrhoea or vomiting

It makes sense to have a working thermometer at home, as an increase in temperature is one of the main symptoms. If you are unsure how to use a thermometer, go to How to take someone's temperature.

What to do

If you have flu-like symptoms, stay at home, take plenty of rest and use over-the-counter painkillers to relieve symptoms. If you are concerned, contact your GP, who will determine the most appropriate action to take.

High-risk groups

For most people, H1N1 flu is a mild illness. Some people get better by staying in bed, drinking plenty of water and taking over-the-counter flu medication.

However, some groups of people are more at risk of serious illness if they catch flu.

It is already known that you are particularly at risk if you have:

  • chronic (long-term) lung disease
  • chronic heart disease
  • chronic kidney disease
  • chronic liver disease
  • chronic neurological disease (neurological disorders include chronic fatigue syndrome, multiple sclerosis and Parkinson's disease)
  • immunosuppression (whether caused by disease or treatment)
  • diabetes mellitus

Also at risk are: 

  • patients who have had drug treatment for asthma within the past three years
  • pregnant women
  • people aged 65 and older
  • young children under five

For most people, the illness appears to be mild. 

For a minority of people, the virus has caused severe illness. In many of these cases, other factors have been identified that are likely to have contributed to the severity of the illness. 

Where complications do occur, they tend to be caused by the virus affecting the lungs. Infections such as pneumonia can develop.
