Adenovirus infection: clinic, forms, treatment
According to research data, adenovirus infection accounts for 3% of adults in the number of other diseases affecting the bronchi, larynx and lungs. In children, the infection rate is even higher: from 12 to 21%.
Adenovirus infection: pathogens
The viruses that cause these diseases first discovered Hubner and Rowe in 1935. They isolated them from the tonsils and adenoids, which were extracted during the operation from healthy children. These infectious agents are called adenoviruses. They consist of particles of polyandral shape (or spherical), which contain DNA, their sizes vary from 80 to 12 MMK. They are characterized by pathogenic effects on human tissue, localization inside the cell nucleus and resistance to adverse environmental conditions.
Adenovirus infection: epidemiology
The reason for its spread are sick people. Pathogens are excreted along with secretions covering the mucosa of the respiratory tract, with feces. Infection occurs very easily, by ordinary airborne droplets.In addition, viruses spread in the same way as pathogens of various intestinal infections. Infection is also possible through the conjunctiva of the eye while swimming in the common pool. Virus isolation can last up to 14-20 days, or even more. Babies from six months to three years are particularly susceptible to infections. Older children and adults are less likely to become infected, since they already have acquired immunity.
Adenovirus infection: clinical forms
The incubation period lasts from four days to a week, less often - longer. Adenovirus infection can occur in several clinical forms. The main ones are pharyngo-conjunctival fever, pneumonia and catarrh of the respiratory tract. Tonsyl pharyngitis, conjunctivitis and keratoconjunctivitis, intestinal form and mesadenitis are less common. Regardless of the type of leakage, the disease is always accompanied by at least a slight pronounced lesion of the larynx or bronchi.
Adenovirus infection: symptoms
Manifestations of the disease depend on the form of flow. For example, with faringo-conjunctive fever, body temperature necessarily increases.There is a lack of appetite, muscle weakness, headache and loss of strength in general.General poisoning of the body is weak. However, babies in the first days of the disease there is a strong vomiting. Persistent symptoms: bronchitis or tracheobronchitis, rhinitis with copious secretions, conjunctivitis, and pharyngitis. Sometimes there are laryngitis and asthma syndrome. The mildest form of infection is catarrh of the respiratory tract. Its main symptoms are rhinitis, bronchitis, pharyngitis and a small fever. The most severe form of adenovirus infection is pneumonia. Severe rales, cyanosis, shortness of breath, and general intoxication are associated with the above symptoms. Sometimes there are convulsions.
Adenovirus infection: treatment
The first is etiotropic therapy. Even when trying to self-cure at the first symptoms of a disease, a person should turn to virocidal drugs, most of which can be taken even at an early age. These are virazol, arbidol, contrycal, oxolinic ointment. This is followed by the reception of immunomodulators (interferon) and immunostimulants (anaferon, echinacea, cycloferon). If there is no improvement after a three-day therapy, go to local and systemic antibiotics.
