Children have fever and red spots on tongue

In fact, when children have a fever, they will definitely show some different symptoms, and each child's symptoms are completely different. Basically, they are all related to the oral cavity. For example, you will feel some red spots on their tongue, which is caused by fever. Some more serious patients will also have rapid breathing, which will affect the treatment.

This group of diseases accounts for 70%-80% of acute respiratory diseases. Composed of rhinovirus, influenza virus, post-influenza virus, adenovirus, and respiratory syncytial virus. It is caused by ECHO virus, Coxsackie virus, etc., and its clinical characteristics are various manifestations. Symptoms of upper respiratory tract infection are mostly mild while symptoms of bronchiolitis and pneumonia are more severe.

The diagnosis is mainly based on clinical manifestations, white blood cell counts, X-ray examinations, and response to antibiotic treatment. In recent years, due to advances in diagnostic technology, rapid diagnostic methods such as immunofluorescence and enzyme-linked immunosorbent assay (ELISA) can be used to identify the pathogen. Common diseases include influenza, common cold, glandular pharyngeal conjunctival fever, herpetic pharyngitis, bronchiolitis, pneumonia, etc. It must be differentiated from bacterial respiratory tract infection.

2. Severe acute respiratory syndrome (SARS)

The disease first broke out in Guangdong Province, China in November 2002. It is a highly contagious pneumonia caused by a coronavirus with fever and respiratory symptoms as the main manifestations. Severe patients can quickly progress to acute respiratory distress syndrome (ARDS) and die.

For patients with SARS epidemiological evidence of fever, respiratory symptoms and lung signs, as well as abnormal imaging changes such as lung X-ray CT, who can rule out other diseases, a clinical diagnosis of SARS can be made. On the basis of clinical diagnosis, the diagnosis can be confirmed if the secretion SARS coronavirus RNA (SARS COV RNA) test is positive, or the serum SARS COV antibody turns positive or the antibody titer increases by 4 times or more.

SARS COV isolation is the "gold standard" for establishing etiological diagnosis. However, its separation is only allowed in a tightly protected p3 laboratory, and the in vitro cell culture separation method is complex and cumbersome, and is not suitable for clinical laboratories.

As a diagnostic tool, any of the following three conditions can be diagnosed as severe SARS:

① Dyspnea, with a respiratory rate of ≥30 times/min in an adult at rest and accompanied by one of the following conditions: chest X-ray shows multilobar lesions or the total area of ​​the lesions occupies more than 1/3 of the total area of ​​both lungs on the frontal chest X-ray; the lesion area increases by >50% within 48 hours and occupies more than 1/4 of the total area of ​​both lungs on the frontal chest X-ray.

②Obvious hypoxemia, oxygenation index <40 kPa (300 mm-Hg)

③Shock or multiple organ dysfunction syndrome (MODS) occurs.
