Influenza
Influenza which is more commonly known as the flu, is an infectious disease caused by RNA viruses of the family Orthomyxoviridae (influenza viruses), that affects birds and mammals. The most common symptoms of the disease are chills, fever, sore throat, muscle pains, severe headache, coughing, weakness or fatigue and general discomfort.
The most frequent symptoms of flu are a sore throat, fever and coughs. More serious cases of influenza can cause pneumonia. This can be fatal especially for the young and the elderly. Although it is often confused with other influenza-like illnesses, especially the common cold, influenza is a more severe disease than the common cold and is caused by a different type of virus.
Ordinarily influenza is spread through the air by coughs or sneezes. Influenza can also be spread by direct contact with bird droppings or nasal secretions, or through contact with contaminated surfaces.
Influenza viruses can be rendered inert by sunlight, disinfectants, and detergents. Frequent hand washing reduces the risk of infection.
If you have the flu, the following is recommended. Stay at home and keep warm, rest, drink a lot of liquids especially water (not alcohol), use over the counter medications, and see a doctor. You must also remain alert for any warning signs that the disease is getting worse. These will include nausea, confusion, dizziness, and abdominal pain.
There are also yearly vaccinations available. These are generally effective in prevention of infection of most strains of flu. For some strains, though the vaccination is limited in terms of availability.
