Signs and symptoms

Some of the major signs and symptoms of swine flu are fever, sore throat, cough, chills, body ache, headache and running nose. Signs and symptoms usually appear one to three days after exposure. Signs and symptoms gradually subside in a healthy individual. But in pregnant ladies and patients with associated respiratory infections need advice from medical personnel. The infection is transmitted via inhalation route i.e. with respiration. It does not transmit with food.

Most of the cases of swine flu require only symptomatic treatment. For management of fever paracetamol is prescribed by the doctor. Like wise for sore throat warm saline gargle is advised. Paracetamol is also helpful to alleviate symptoms like body ache and headache.
