Swine flu signs and symptoms in humans are similar to those of other flu strains:
- Sore throat
- Runny or stuffy nose
- Body aches
Swine flu symptoms develop about one to three days after you're exposed to the virus and continue for about seven days.
When to see a doctor
It's not necessary to see a doctor if you're generally healthy and develop flu signs and symptoms, such as fever, cough and body aches. Call your doctor, however, if you have flu symptoms and you're pregnant or you have a chronic disease, such as emphysema or a heart condition.
