Influenza!!!
Jun 30, 2008Influenza, commonly called flu, is an acute respiratory illness. It is caused by a virus which attacks the lining of the air passages, the nose, throat, windpipe and lings, leading to inflammation. The virus is usually passed form one person to another through the air, and the illness often breaks out as an epidemic, quickly spreading from town to town and country to country. The epidemic conditions usually last for a period of four to six weeks before they ease off.
Every few years a new strain of flu appears that spreads so rapidly those precautions cannot be developed in time. This can lead to pandemics – international epidemics – which threaten millions of lives.
Symptoms:
Many people confuse flu with the common clod. Both colds and flu are caused by a virus nut the symptoms of flu are usually much more severe than those of a cold and include a high temperature. Flu also tends to have a more sudden onset than a cold.
Flu symptoms include:
•Fever.
•A cough;
•A sore throat;
•Headache;
•Lack of appetite;
•Severe muscle aches and pains;
•Extreme fatigue;
•Later, a runny nose and sore throat.
The majority of healthy people with flu can treat the illness themselves.
•As a medicine like Paracetamol can relieve the high fever and ache and pains.
•Plenty of bed rest and sleep are needed, in a well-ventilated, warm room.
•Drink such a hot lemon with honey can easy to cough.
•Plenty of juices and water are needed – the fever causes sweating and dehydrates the body.
•Avoid smoking or drinking alcohol.
A doctor may prescribe antibiotics if you develop any complications, such as bacterial infection in the lungs. Antibiotics are not effective against the flu virus itself, which will be dealt with by the body’s own defenses.
There are two antiviral drugs, zanamivir and oseltamivir, which can be used to treat flu. But they are not widely prescribed because they have been shown to reduce the duration of flu by only one day. To be effective, they have to be taken within 36 hours of the onset of flu.
Very serious cases of flu may be referred to hospital for treatment.
