Many of the „flu” ideas are clear, there are many misunderstandings. In fact, the „flu” flu (influenza abbreviation), feeling (upper respiratory tract infection abbreviation) perception is different, crushing also treatment strategies also not exactly. Although hold office cold and flu arborvirus an infection caused by the respiratory tract, but they are two different diseases. Influenza, referred to as influenza, is caused by a virus acute respiratory infection, the higher incidence, easy cause explosive popularity or pandemic, pathogens owing to amour, second, third 3 forms of influenza illness poison, mainly through airborne. Clinically in urgent up high fever, fatigue, systemic muscle ache, eye infections clear and mild respiratory symptoms, although have self-limited, however the elderly and concomitant chronic respiratory disease, middle disease is apt to coincidental pneumonia. The main characteristic is flu epidemic, can cause regional, national, and consistent around the globe pandemic, so popular is the main clinical diagnosed according to influenza. Because of the flu virus especially influenza illness poison extremely easily, so every year transpire variation of influenza strains, or virus blood serums often is different, generally 3 age connections a popular height, pathogenesis number, systemic symptom serious, the influence is healthy and labor ability. In January this year, Hong Kong ten vice influenza viruses bob up four popular, caused serious influence. The common cold, abbreviation colds, frequently frequent as „catch a cold” is acute viral greater respiratory nation infection, the most common disease, besides the fact that children occur in winter, but any season, jibing as spring, summer can also occur, contrasting seasonal cold disease-causing viruses is not exactly the same. Its main pathogens nasal virus, secondly bade influenza virus, adenovirus, Egypt viruses and respiratory syncytial virus, often easily merged bacterial infections. The common cold rush is nasty, early symptoms have pharyngeal dry itch or burning, including nasal congestion, sneezing, runny nose, began to clear water, 2 ~ 3 days thickened, Can accompany pharynx pain, General no fever and systemic symptom, or only a low-calorie, headache. The common cold is in general sporadic, not cause popular, however corona virus infection answerability cause some popular. Colds a self-limited, generally through 5 ~ 7 days healed. contagion prevention measures mainly include: 1. The early detection of contagion patients, early in situ isolates the patients again leading treatment. right through popularity should reduce large rallies and collective activity, to the public should wear a face mask, much less discrepancy densely populated location. We can every times ventilate, maintain interior air fresh. 1. Drug prevention: Amantadine hydrochloride crushing influenza a have certain effect of patients with hepatitis b influenza is invalid. So, in the popular slightest must determine the epidemic strains of type do not to sitting duck population drug crushing. 3. immunogen to prevent: average vaccine has reduced poison vaccines and inactivated vaccine in two. With nasal spray poison immunogen reduced by subcutaneous method, inactivated vaccine injections. It can a extent later ~ prevention vaccination harbour influenza role. But the influenza virus strains often variation, so hard to predict this year popular arborvirus type, can only speculate may be type, manufacturing vaccine strain to bring about pestilential strains.
