Many people wonder whether a cold in summer is a hot cold? And how to distinguish so many "hot" colds, such as wind heat colds and summer heat colds? In addition, at this stage, influenza (influenza) is rampant in southern provinces. What is the difference between the above cold types and influenza? Yangcheng Evening News reporter interviewed Professor Yi Gao, an expert in respiratory medicine of the Fifth Affiliated Hospital of Guangzhou Medical University, on common problems related to colds. Yangcheng Evening News: is a cold in summer a hot cold? How to treat? Yi Gao: what we call hot cold (wind hot cold), cold cold (wind cold cold), summer hot cold, etc. are classified from the perspective of traditional Chinese medicine, with different clinical symptoms as the main differences. In summer, you may catch cold due to rain, excessive use of air conditioning, etc., which is generally considered to be wind cold. At this time, you will have symptoms such as runny nose and chilly, which can be treated with cold medicine with pungent and warm relieving effect and dispersing wind cold effect; Wind heat colds usually have symptoms such as runny nose, cough, sore throat and so on. Use cold drugs with the effects of cooling the skin and clearing away heat and toxin; The summer fever cold mainly occurs when the humidity is heavy and the temperature is high. It often shows fever, stuffy nose, chest tightness, poor appetite, thick and greasy tongue coating, etc. you can choose drugs with the effects of clearing summer heat, removing dampness and relieving exterior. Consult a doctor before taking medicine and treat according to syndrome differentiation. Yangcheng Evening News: are cold and hot colds common cold or flu? Yi Gao: epidemiological data show that 80% - 90% of colds are caused by viruses, among which viral colds are subdivided into common cold and influenza. Hot and cold colds can generally be regarded as common syndromes in the common cold, so they also include the relevant symptoms mentioned above. Western medicine is generally symptomatic treatment, but at the same time, considering that patients with chronic respiratory diseases such as nasopharyngitis and tonsillitis are also prone to "catch" the common cold, it is necessary to take drugs under the guidance of doctors to avoid aggravation of the disease. Yangcheng Evening News: how to distinguish between common cold and flu? What department should I hang up if I go to the hospital? Yi Gao: common cold is mostly "local" respiratory symptoms, such as stuffy nose, runny nose, sneezing, sore throat, etc., without fever or only mild fever; Influenza mostly has severe "systemic" symptoms, usually high fever (≥ 39 ℃), obvious systemic pain and fatigue, and relatively mild respiratory symptoms. At present, the common cold is generally linked to the "respiratory department" of the hospital; Influenza has obvious symptoms of high fever, and now it is in a special stage of epidemic prevention, so it should go to the "fever clinic" of the hospital as soon as possible. Fever clinics will screen not only covid-19, but also fever caused by influenza virus. In addition, the vast majority of common cold treatment has no special specific drugs, mainly symptomatic treatment and relief of cold symptoms. Influenza can be injected with the corresponding vaccine. In the early stage of treatment, oseltamivir, a specific inhibitor of neuraminidase, is often used for treatment, which needs to be taken under the guidance of doctors. (outlook new era)
