Influenza
Medical Questions » Influenza
| Name: Influenza |
| Also known as: Flu |
| Debilitating generalized viral infection. Influenza was once thought to be due to ' influences in the atmosphere' , thus giving its name. The various flu virus strains are named after the places where they were first isolated. |
Causes of Influenza
Viral infection by one of the more than 80 known strains of the influenza virus. Spreads by microscopic droplets in a cough or sneeze from one person to another. |
Symptoms of Influenza
Muscular aches and pains, overwhelming tiredness, fever, headache, cough, runny nose, stuffed sinuses, painful throat and nausea. |
Tests for Influenza
None normally necessary, but throat swabs or blood tests can identify the responsible strain of influenza. |
Treatment for Influenza
Can now be cured, but only if the inhaled medication (zanamivir) is given within the first 36 hours of symptoms developing. Otherwise rest and time, aspirin, anti-inflammatory drugs and medications to help the phlegm and cough are given. A light nutritious diet that contains minimal fat, and a higher than normal fluid intake are sensible. Flu can be prevented by an annual vaccination which gives more than 80% protection from contracting the infection, but only for one year. Unfortunately the vaccine does not prevent the common cold, and many people who complain that their flu shot has not worked are suffering from a cold caused by yet another group of viruses. Amantadine tablets will prevent some forms of flu while they are being taken.

Complications of Influenza of its treatment
Can be a very serious disease, but deaths are now rare except in the elderly and debilitated. Secondary bacterial infections of the throat, sinuses, lungs and ears may occur, which can be treated with antibiotics. |
Likely Outcome of Influenza
Influenza normally lasts for seven to ten days. The vast majority of patients recover without complications. |
