What is Flu?

Influenza, commonly known as the flu, is caused by RNA viruses and affects the respiration system of most mammals, birds and human beings. The infection causes fever, cough, headache, nausea and tiredness. In most cases, vomiting and diarrhea accompanies the illness.

Causes of Flu

The commonest types of viruses that cause the flu are the influenza viruses. They are divided into three types and designated the codes A, B and C. While types A and B are responsible for most epidemics of illness around the world, C usually causes a very mild illness with no big symptoms. It is a scientific fact that types A and B are responsible for most hospitalization and deaths in the world. Influenza viruses have the ability to mutate with time. This helps the virus beat the immune system of human beings.

Medication for Flu

Since flu is one of the most common diseases for the human race, there are a few effective and time proven drugs which are designed to reduce the burden of pain. Some good drugs are Vicks Nyquil, Theraflu and Oscillo. Action 500 and nose block ointments are effective to cure body aches and running noses. Flu medication contains pain killers that induce drowsiness in the body. Therefore, care should be taken to take the correct amount or dosage.

Prevention of Flu

The important fact about flu remains that it is a communicable disease. Absolute isolation is essential to keep the patient from giving the illness to others. Anti-viral vaccines have to be administered to the people around the patient to ensure that it does not spread. If the patient’s household contains young children and people above the age of 55, care should be taken to prevent the disease from spreading to them by quarantining the patient from them. People with immune-deficiency syndrome and diabetes and asthma have to be vaccine-administered. Further, good healthy habits like washing your hands with soap and water frequently and covering your coughs and sneezes can help reduce the infection.
