A guide on Influenza covering signs and symptoms, prevention & treatment.
Influenza, commonly known as "the flu", is an infectious disease caused by an influenza virus.Symptoms can be mild to severe.The most common symptoms include: high fever, runny nose, sore throat, muscle and joint pain, headache, coughing, and feeling tired.These symptoms typically begin two days after exposure to the virus and most last less than a week.The cough, however, may last for more than two weeks.In children, there may be diarrhea and vomiting, but these are not common in adults.Diarrhea and vomiting occur more commonly in gastroenteritis, which is an unrelated disease and sometimes inaccurately referred to as "stomach flu" or the "24-hour flu".Complications of influenza may include viral pneumonia,secondary bacterial pneumonia, sinus infections, and worsening of previous health problems such as asthma or heart failure.
Three of the four types of influenza viruses affect humans: Type A, Type B, and Type C.Type D has not been known to infect humans, but is believed to have the potential to do so.Usually, the virus is spread through the air from coughs or sneezes.This is believed to occur mostly over relatively short distances.It can also be spread by touching surfaces contaminated by the virus and then touching the eyes, nose, or mouth.A person may be infectious to others both before and during the time they are showing symptoms.The infection may be confirmed by testing the throat, sputum, or nose for the virus.A number of rapid tests are available; however, people may still have the infection even if the results are negative.A type of polymerase chain reaction that detects the virus's RNA is more accurate.
