Ways of infection

  • fecal-oral. In the midst of the disease viruses are excreted with the feces;
  • water. Adenovirus not sensitive k hloru, so the child can catch it, sip of water in the pool or from the tap.

As the majority of viruses, to adenovirus in humans formed a strong immunity, but there is a possibility to be ill due to another type of adenovirus.

In a human body, the virus migrates to the body, until it reaches the lymph nodes, epithelial cells and intestinal lymphoid formations. Then he begins to actively proliferate, penetrating into the DNA of cells and disrupting their work. Less than a day new viruses are formed in the destroyed cells of the body. Since the release of new adenovirus into the bloodstream ends incubation period, there are the first symptoms of the disease. The infection affects the nasal mucosa, tonsil, eye shell, spreading the bronchi and alveoli. Sometimes the virus breaks bowels, liver, spleen. In rare cases, the infection gets to the brain, it provokes edema, after which death occurs.

Since the individual features of adenovirus may be part of other diseases, it is impossible to diagnose disease. The doctor suggests adenoviral infection on the basis of such features:

  • conjunctivitis;
  • catarrh of the respiratory organs;
  • proliferation and inflammation of the mucous tissue of the pharynx;
  • polyadenylation;
  • heat;
  • priority, in which there are signs of.

To confirm the diagnosis the doctor prescribes the child a number of analyzes, namely: swab from the nose, smear of the conjunctiva, RTGA, RSC, IFA, REEF, İEM. Such assays also sometimes prescribed for influenza, diphtheria, acute respiratory diseases, different types of SARS, to insure, that viral infection adenovrusnaya.
