General discomfort

Introduction Physical symptoms caused by physical illness, generally headache, insomnia, appetite discomfort, palpitation, chest tightness, etc., people get flu, often showing general discomfort. In general, the discomfort of the whole body is uncomfortable. Human influenza is a human acute respiratory infection caused by influenza A, B, and C viruses. The influenza virus has eight different independent gene segments, which determine the genetic rearrangement of the influenza virus. Gene rearrangement has played a key role in the production of new influenza virions and in the pandemic of human influenza.

Cause

Human influenza is a human acute respiratory infection caused by influenza A, B, and C viruses. The influenza virus has eight different independent gene segments, which determine the genetic rearrangement of the influenza virus. Gene rearrangement has played a key role in the production of new influenza virions and in the pandemic of human influenza.

It is generally believed that pigs play an important role in the formation of this hybrid virus and are considered to be "mixers" because pigs have cellular receptors for both viruses, and both human and avian influenza viruses can infect pigs. After a period of hybridization, a new rearranged virus is produced, which infects people, causing the epidemic of human influenza.

The clinical characteristics are related to the virus strain, age and physiological status of the population, mainly including fever, chills, dry cough, headache, sore throat, general discomfort, fatigue, nasal congestion and salivation. The disease has a short incubation period, is highly contagious, and spreads rapidly. It is harmful to infants, young people and people with weak constitution. Blood tests, chest radiographs, and liver function tests are performed in a timely manner. Conditions allow for vaccination before the high season of influenza.

Differential diagnosis

Clinical attention should be paid to the differential diagnosis of diseases such as influenza, common cold, bacterial pneumonia, infectious atypical pneumonia (SARS), infectious mononucleosis, cytomegalovirus infection, chlamydial pneumonia, and mycoplasmal pneumonia.

1, the common cold: caused by a variety of viruses, mostly sporadic, slow onset, upper respiratory symptoms, systemic symptoms are lighter. Cold, commonly known as cold, also known as acute rhinitis or upper respiratory catarrh, is the main manifestation of catarrhal symptoms in the nasopharynx. Adults are mostly caused by rhinoviruses, followed by parainfluenza viruses, respiratory syncytial virus, echovirus, Coxsackie virus, and the like.

The onset is more urgent. In the early stage, there is dry throat, itchy itch or burning sensation. At the same time or several hours after the onset, there may be sneezing, nasal congestion, and clear watery nose, which will thicken after 2~3 days. May be associated with sore throat, sometimes due to eustachian tube inflammation, hearing loss, tearing, slow taste, poor breathing, hoarseness, a small amount of cough. Generally no fever and systemic symptoms, or only low fever, discomfort, mild chills and headaches. Check the nasal mucosa congestion, edema, secretions, mild congestion of the pharynx. If there is no complication, it usually recovers within 5-7 days.

2, influenza typhoid leptospirosis: multiple in summer and autumn, history of exposure to water, clinical fever, gastrocnemius tenderness, inguinal lymphadenopathy, tenderness, laboratory tests can be detected by coagulation test, if the antibody titer is Increased by 1:400 or more, considering the disease, it can be diagnosed by blood culture.

3, streptococcal pharyngitis: the disease is swollen in the throat, tonsils, purulent secretions, submandibular lymph nodes, WBC neutrophils increased, blood culture ().

4, other viral respiratory infections: such as parainfluenza virus, adenovirus infection to be distinguished by pathogenic examination.

5, mycoplasmal pneumonia: also through the pathogen examination to distinguish.
