Paratyphoid A and B - is acute infectious diseasethat in its manifestations are similar to typhoid fever. Pathogens - motile bacteria of the genus Salmonella, resistant in the external environment, disinfectants in usual concentrations kill them in a few minutes. The only source of infection at paratyphoid A are sick people and carriers of bacteria that only separate them, but they do not get sick, and at paratyphoid in them can be animal (cattle, etc.). The bacteria enter the body with soil particles on poorly washed fruits and vegetables on hand, etc. In addition, particles may be carried small rodents, such as mice. The rise of the incidence begins in July, peaking in September and October. Sensitivity to human bacteria is very high and does not depend on age and sex.

Accompanied by nausea, vomiting, loose stools, as well as a cough and runny nose, possible facial flushing, exacerbation of herpes. The rash usually appears on the 4-7 day of illness, often abundant. In the course of the disease is usually several waves rash. The temperature is increased. When paratyphoid A great opportunity to re-emergence of the disease than the paratyphoid B and typhoid.
The incubation period is much shorter than withparatyphoid A sign of a great variety. When the transmission of infection through the water there is a gradual onset of the disease is relatively easy for him. When bacteria enter along with food, predominant gastrointestinal events (nausea, vomiting, diarrhea), followed by the development and spread to other parts of the process.
When paratyphoid The more frequently than in paratyphoid A and typhoidfever, observed mild to moderate forms of the disease. Re-development of the disease is possible, but is less common. The rash may be absent or, on the contrary, be abundant, diverse, come early (4-7 day of illness).
Treatment of paratyphoid A and B should be comprehensive,including care, diet, antibiotics, and if necessary - drugs that increase immunity. Bed rest is up to 6-7 days of normal temperature, with 7-8 days is permitted to sit, and a 10-11 walk. Food should be easily digestible, sparing the stomach and intestines. During her fever steamed or give to shabby.
Among the leading place it takes antibioticschloramphenicol, which is used up to 10 days of normal temperature. To increase the effectiveness of antibiotics, primarily to prevent relapse, they combine with the means of stimulating the body's defenses.
Prevention paratyphoid A and B is reduced togeneral sanitary measures: improving the quality of water supply, sanitation and sewerage populated areas, the fight against flies, etc. all been ill observed by a doctor within 3 months from the date of recovery..
