In fact, the „flu” flu (influenza abbreviation), feeling (upper respiratory tract infection abbreviation) concept is different, prevention further treatment methods also now not exactly. although be cold and flu virus infection caused by the respiratory tract, but they are two altered diseases.
Influenza, referred to as influenza, is caused by a virus uttermost respiratory infection, the higher incidence, easy cause explosive popularity or pandemic, pathogens for amour, second, 3 three types of influenza illness poison, mainly through airborne. Clinically grease urgent up high fever, fatigue, systemic muscle ache, eye infections clear and mild respiratory symptoms, youngsters have self-limited, but the elderly and concomitant chronic respiratory disease, heart disease is well-suited to concurrent pneumonia. The main characteristic is flu epidemic, contract cause regional, national, and even worldwide pandemic, therefrom popular is the principal clinical diagnosed according to influenza. as a result of of the flu virus especially influenza illness poison extremely easily, thus every year happen variation of influenza strains, or arborvirus blood serums commonly is different, generally 3 dotage in a popular height, pathogenesis number, systemic symptom serious, the influence is fit and labor ability. In jan this year, Hong Kong showy vice influenza viruses appear four popular, caused viperous induce.
The common cold, abbreviation colds, commonly ordinary as „catch a cold” is acute viral upper respiratory tract infection, the inimitably common disease, although occur in winter, but any season, such as spring, summer can also occur, different seasonal bloodless disease-causing viruses is not exactly the same. Its main pathogens nasal virus, secondly bade influenza virus, adenovirus, egypt viruses besides respiratory syncytial virus, often easily merged bacterial infections. The common cold violation is nasty, early symptoms have pharyngeal dry itch or burning, including nasal congestion, sneezing, liquid nose, started to clear water, 2 ~ 3 life thickened, Can accompany pharynx pain, General no feverishness and systemic symptom, or only a low-calorie, hot water.

We can every times ventilate, maintain interior temperament supplementary.
2. Drug prevention: Amantadine hydrochloride crushing influenza a have certain effect of patients with hepatitis b influenza is invalid. So, in the popular early must determine the pestilential strains of type don’t to unsafe population drug prevention.
three. Vaccine to prevent: common vaccine has reduced poison vaccines and inactivated vaccine in two. With bone spray poison immunogen reduced by subcutaneous method, inactivated vaccine injections. It fault a duration later ~ prevention vaccination with influenza role. But the influenza virus strains commonly variation, hence hard to predict this year popular arborvirus type, can only speculate can also be type, manufacturing vaccine strain to close epidemic strains.
