What are the specific symptoms of adenovirus pneumonia in infants and young children?

Adenovirus pneumonia is relatively common among infants and young children. Many parents and friends do not understand the symptoms of this disease well, and it is often ignored, causing the disease to worsen. So today, the editor will share with you the specific symptoms of this disease. Let’s watch it together!

Diagnosis of adenovirus pneumonia Adenovirus pneumonia perspective

The diagnosis should be made based on the epidemic situation and combined with clinical practice. The differences between typical infant adenovirus pneumonia and common bacterial pneumonia in the early stage are:

① Most cases have persistent high fever at onset or soon after onset, and antibiotic treatment is ineffective;

② From the 3rd to the 6th day of the disease, neurological symptoms such as drowsiness and lethargy appear. Drowsiness sometimes alternates with irritability. The face becomes pale and gray, and the liver is significantly enlarged. Complications such as heart failure and convulsions are likely to occur later. The above symptoms suggest that adenovirus pneumonia not only involves the respiratory tract, but also affects other systems;

③ Lung signs appear later, usually with moist rales appearing after the 3rd to 5th day of illness, the area of ​​lesions gradually increasing, dullness to percussion and decreased breath sounds, and wheezing and dyspnea becoming increasingly severe on the second day of illness;

④ The total white blood cell count is low, with most patients not exceeding 12×109/L (12000/mm3), and the neutrophil count not exceeding 70%. The alkaline phosphatase and tetrazolium blue staining of neutrophils are significantly lower than those in cases of purulent bacterial infection, but will rise again if purulent bacterial infection occurs;

⑤X-ray examination of the lungs may reveal large flake-like shadows, most commonly in the lower left area.

In short, during this epidemic season, when infants and young children develop severe pneumonia and their X-ray and blood test results are consistent, a preliminary diagnosis can be made. Units with the conditions can conduct rapid diagnosis of the virus. Currently, immunofluorescence technology (the indirect method is more applicable than the direct method), enzyme-linked immunosorbent assay and specific IgM assay can be used. However, these three methods cannot type adenovirus, which is their shortcoming. Routine throat swab virus isolation and double serum antibody testing are only suitable for retrospective diagnosis in the laboratory.

Through the editor’s sharing above, do you have a clear understanding of the symptoms of this disease? Therefore, in the future care of infants and young children, we must be careful. If any adverse symptoms are found, we should seek medical attention in time to avoid delaying the disease.
