What symptom is virus cold

summary

Most people don't know about viral cold, and few people encounter it. However, we still need to understand that viral cold is a common disease, including common cold, influenza and viral pharyngitis. It is mainly transmitted through the nose through air or hand contact. Influenza is an acute respiratory infectious disease caused by influenza virus. The virus exists in the patient's respiratory tract and is transmitted by droplets when the patient coughs and sneezes. Because of its strong infectivity, difficult to control the route of transmission, fast transmission speed and wide range of transmission, it is difficult to control and has great harm, and even severe cases (severe pneumonia, respiratory failure, etc.) will appear. Common cold is caused by rhinovirus, coronavirus and parainfluenza virus. The infectivity of common cold is much weaker than that of influenza. It often occurs individually. When the body's resistance decreases, it is easy to get sick. Let's share some experience.

What symptom is virus cold

First: cold is a non communicable disease, seasonal is not obvious, patients generally do not have fever or moderate fever, no shivering, few or no systemic symptoms, course of 1-3 days, few complications such as otitis media, pneumonia and encephalitis. Influenza is a class C infectious disease with obvious seasonality. Most of the patients have high fever of 39 ° C-40 ° C, accompanied by shivering. The course of disease is 3-5 days. The systemic symptoms are obvious, such as headache, muscle soreness, fatigue, and complications such as otitis media, pneumonia, encephalitis, etc.

Second: hemogram, white blood cell count decreased, lymphocytes increased, combined with bacterial infection, white blood cell count and neutrophils increased.

Third: the antigen was detected by immunofluorescence or immunoenzyme staining, and the antigen was detected by immunofluorescence or enzyme labeled influenza virus immune serum staining. It is helpful for early diagnosis.

matters needing attention

Antibiotics are used to resist bacteria and have no effect on viruses, so the abuse of antibiotics has no therapeutic effect when it produces toxic and side effects. In addition, the abuse of antibiotics will lead to the emergence of a large number of drug-resistant strains. Experts suggest that, in general, it is not appropriate to take antibiotics on your own unless you have a cold with yellow pus, nasal discharge and fever; when you have severe cold symptoms or complicated with other symptoms, you should see a doctor in time, and choose antibiotics under the guidance of a doctor when you have bacterial infection or complications.
