BK 3101

No. 3101 of the Annex to the BKV covers diseases that are transmissible from person to person. These diseases are generally covered by BK No. 3101 if they occur in insured persons who are exposed to a significantly higher risk of infection than the general population as a result of carrying out their professional activities in certain areas.

This mainly applies to staff in inpatient or outpatient medical facilities in human medicine and dentistry, in welfare care facilities and laboratories. In addition, people working in these areas for short periods of time, such as maintenance, repair or disposal, may also be affected. A similar level of risk may also exist in activities in genetic engineering, biotechnology, wastewater and sewage treatment plants.

The pathogens can be absorbed via the non-visibly injured (micro-lesions) or injured skin or mucous membrane (trans-, percutaneous infection as contact or smear infection), via the respiratory tract (aerogenic infection as droplet or dust infection), parenterally (puncture or cut injury) or via the digestive tract (oral infection, smear infection). As a result of ingestion of the pathogen, either local or systemic infections occur after different incubation periods, with or without the appearance of symptoms. The course of the infection involves a process in which several defense mechanisms of the immune system become effective in a way that is typical for each pathogen.

The diagnosis must be confirmed by virological, bacteriological, serological and, if necessary, type-differentiating tests, taking into account the incubation period. For all viruses with existing subtypes, it is possible - via genomic analysis of the viruses of the source of infection and the insured person - to reliably identify or exclude the source of infection. This is also possible for some bacteria by means of restriction enzyme analysis.

Important clinical pictures are:

• Viral hepatitis
  • Viral hepatitis A
  • Viral hepatitis B
  • Viral hepatitis C
  • Viral he patitisD (synonym: delta hepatitis)
  • Viral hepatitis E
  • Tuberculosis
• HIV infection/AIDS

For a reasonable suspicion of the existence of an occupational disease, there must be a temporal connection between the exposure to the pathogen in question and the disease. The disease must develop within a period of time that is within the incubation period. In the case of inapparent diseases, the development of the relevant stage and the possible sequelae of the infectious disease should be considered. The route of transmission and the infectiousness of the pathogen must be taken into account.

Persons who are carriers without being clinically ill themselves can also be considered as a source of infection. If an intrauterine infection or damage to the health of the foetus occurs as a result of an occupationally acquired infection during the pregnancy in question, compensation for the child must be considered in accordance with § 12 SGB VII. Gregg's syndrome - rubella embryopathy - following occupational rubella infection of the pregnant woman, with or without incapacity to work, is a well-known example of this, as are infections with HAV, HBV (risk of infection up to 100%), HCV, HIV, varicella zoster and cytomegalovirus. Infectious diseases that are transmitted from animals to humans or are tropical diseases are covered under BK numbers 3102 or 3104, even if they were acquired during the above-mentioned activities.
