Symptoms of the Pandemic influenza are similar to those of seasonal ordinary flu which manifest in fever, running nose, sore throat, headache and fatigue.

There are now over 125,000 laboratory-confirmed cases of swine flu worldwide but the WHO acknowledges the number of actual cases far exceeds that.
