Diagnosis & Treatment
Diagnosis is generally made by history and physical examination and confirmed by laboratory studies, such as blood tests (ELISA antigen test) and culture of nasopharyngeal swab; X-rays of the chest (only for complications).
- To relieve nasal congestion, use salt-water drops (1 teaspoon of salt to 1 quart of water);
- To relieve a sore throat, gargle often with warm or cold, double-strength tea or salt water or commercial products;
- Use a cool-mist humidifier to increase air moisture. This thins lung secretions so they can be coughed up more easily. Don’t put any medicine in the humidifier, it does not help. Clean humidifier daily;
- To avoid spreading germs to others, wash your hands frequently, especially after blowing your nose or before handling food;
- Use warm compresses or heating pad for aching muscles.
- For minor discomfort, you may use non-prescription drugs, such as acetaminophen, cough syrups, nasal sprays or decongestants;
- Do not take aspirin. Some research shows a link between the use of aspirin (especially in children) during a virus illness and the development of Reye’s syndrome (a type of encephalitis);
- An antiviral drugs, amantadine or rimantdine, for seriously ill persons or for those at greatest risk from complications may be prescribed.
Rest is the best medicine. If you are in good health, rest helps your body fight the virus.
- Appetite is usually lacking. You may just want liquids at first, then progress to small meals of bland starch foods (dry toast, rice, pudding, cooked cereal, baked potatoes);
- Drink at least 8 glasses a day (especially if you have a high fever). Extra fluids, including fruit juice, tea and non-carbonated drinks, also help thin lung secretions.
- Bacterial infections, including bronchitis or pneumonia;
- These can be especially dangerous for immuno-compromised patients, chronically ill persons or those over age 65.
Spontaneous recovery in 7 to 14 days if no complications occur. If complications arise, treatment with antibiotics is usually necessary, and recovery may take 3 to 6 weeks.
