Adenovirus infection Use Doxycycline
Adenovirus infection belongs to the group of SARS. The disease is accompanied by a loss of lymphoid tissue and mucous membranes of the respiratory system, eyes, intestines and moderate symptoms of intoxication buy doxycycline online.
Causes of adenovirus infection
Disease virus contains double-stranded DNA, which is covered capsid that helps the pathogen to be relatively stable in the environment at low temperatures and drying at room temperature, the virus remains active up to two weeks. The pathogen also exhibits resistance to ether, chloroform, a soap solution, that is, to an alkaline environment, are killed by boiling and under the influence of disinfectants. The virus consists of three pathogens (antigens) (Ar): "A", "B" and "C", which recites several varieties. Various combinations of certain factors make possible the existence of approximately 90 serovars, or variations of adenoviral Viron, of which about six are dangerous to humans.
The source of infection is a sick man: he is released into the environment a virus with nasal mucus and nasal, and in the later stages of the disease - and even faeces. There is a possibility of infection from the virus carriers and that are about 95% of the population. Ways of infection are considered to be airborne and fecal-oral. The maximum susceptibility to the disease showing children aged 6 months to 5 years, during breastfeeding babies under three months have passive nonspecific immunity. For pathology characterized by outbreaks in the cold time of the year due to lower the body's defenses.
The symptoms of adenovirus infection
The incubation period of the disease begins with the exciter contact with the epithelial cells of the mucous membranes and lasts from 1 to 13 days. At this time, the virus attaches to cells and incorporated into their core there is a development of its own DNA of the pathogen due to suppression of cellular DNA, at the next stage, the affected cells are killed. After maturation of the virus and the formation of the mature pathogen begins prodromal period that accompanies all of SARS. The disease continues for 10 to 15 days. A characteristic feature of adenovirus infection is considered to organ damage in a particular sequence: the nose, tonsils, pharynx, trachea, bronchi, conjunctiva, cornea, intestinal mucosa. Also consistent are replacing each other, and the symptoms of adenovirus infection. At the initial stage of the disease can occur acutely or be characterized by the gradual development of symptoms, it all depends on the condition of the body's defenses. Initially marked symptoms of intoxication, for the second and third days are characterized by fever up to high values, swelling of the nasal mucosa, nasal discharge serous then mucous and purulent character. Tonsils blush, they point appears whitish coating, increase in size submandibular and cervical lymph nodes. Further there is organ damage of the upper respiratory tract: the pharynx, trachea, bronchi, develops laringofaringotraheit, then joins bronchitis. The symptoms of adenovirus infection, thus, appear in a certain order and are characterized by hoarseness, dry cough, which replaced the wet comes. There have wheezing, do not disappear after coughing and accompanying inhalation and exhalation. Over time, patients start to bother shortness of breath, with the participation of the muscles intercostal spaces. On examination, it marked cyanosis in the nasolabial triangle, indicating the involvement in the pathological process of the cardiovascular system. Severe manifestations of the disease are most common for young children, which is associated with hyperreactivity reaction lung tissue. In the propagation of infection to the conjunctiva and cornea begins keratoconjunctivitis, which is accompanied by a sharp pain in the eyes, excessive tearing, redness and swelling of the mucous membrane of the conjunctiva, sclera injection. Widespread is also the formation of films on the conjunctival membrane. With involvement in the pathological process of intestinal mucosal hyperplasia occurs it lymphoid tissue, swollen lymph glands in the intestine, which is accompanied by pain in the navel wearing paroxysmal in nature, and pain in the right iliac region. Also, patients concerned about violation of intestinal function.
