Hosting

Hosting - hosting human pathogens of contagious disease, often in the absence of signs of the disease. Long carriage often supported concomitant inflammatory diseases (angina, colitis, cholecystitis , and others), and parasitic infection.
Possible carrier of pathogens of typhoid, paratyphoid a and b, Salmonella , C and D, bacterial dysentery, cholera, diphtheria, cerebrospinal meningitis, scarlet fever and other Installed virusencyclo number of pathogenic viruses. However, in most cases virusencyclo accompanies hidden, latent flowing disease. From latent flowing viral diseases in which there is a carrier, it should be noted polio, epidemic hepatitis; it is also possible carriers of the virus herpes simplex, adeno, etc. is Not found, the carrier of pathogens of measles, smallpox, typhus, typhoid, Sapa, anthrax.
There are three categories of media: healthy people, convalescents and immune. Healthy carriers (carrier without prior disease) are usually pathogens in a short time.
Among healthy carriers include people that produce pathogen in the last days of the incubation period.
Media - convalescents produce pathogen some time after clinical recovery. More often such carriage short. After some infectious diseases carriage disease becomes chronic and lasts 3-4 months. (diphtheria) and even 10 years or more (typhoid fever).
Immune media - persons who are not sick due to previous illnesses or as a result of effective immunization.
Carrier detect by allocating pathogen laboratory method.
Given interspersed character carriage (fluctuations in the amount of germs), the media can be recognized as free from pathogenic microbe only in the event that two or three studies produced in a row, one after the other for several days, will be with a negative result.
Although the media produce significantly fewer pathogens than the patient, it epidemiological danger as a source of infection is high and depends on the profession of the carrier (carrier of pathogens of any intestinal infection is particularly dangerous if it works in the food industry, media diphtheria bacilli in children's institution), housing conditions, health and hygiene skills, etc.
Prevention of bacteria carriage is achieved early hospitalization of patients, and therefore, the appointment of early rational therapy, discharge patients not previously full clinical recovery.
In order to prevent mass infection by bakterionositeli workers of food enterprises, kindergartens systematically examined for possible hosting.
This preventive work is conducted on sanitary-epidemiological stations.
Treatment bakterionositelej earlier it used to be ineffective.
Currently, the use of antibiotics and bacteriophages allows in many cases to free people from carrying the bacteria. Cm. also Parasitological.
