Symptoms
-
According to KidsHealth.org, viral lung infections cause a cough that produces small amounts of mucus, a low-grade fever, wheezing, muscle aches and exhaustion.
Warning
-
You can catch a viral lung infection from an infected person who sneezes or coughs near you, or with whom you've shared eating utensils or cups.
-
Time Frame
-
The incubation period---the time between exposure and the appearance of symptoms---varies from less than a day to nearly a week. Duration of the illness also depends on the virus causing it. You may be sick for as little as seven days, or as long as a month, says KidsHealth.
Treatment
-
Antibiotics are typically not given for viral illnesses, although your doctor may prescribe such medication for pneumonia. Fluids and rest are recommended, with over-the-counter remedies for fever and body aches. A hospital stay is indicated if symptoms include a high fever or respiratory distress, says KidsHealth.
Prevention
-
Vaccinations may prevent viral lung infections, and are recommended if you have asthma or chronic illnesses that compromise your immune system, reports KidsHealth. Antiviral medication may also be available.
