When evaluating and assessing infectious and parasitic occupational diseases we encounter some special features. In particular the following specific features are involved: 1. Assessment and notification of these diseases usually takes place at a time When these diseases no longer persist. 2. A certain infectious or parasitic disease can be recorded and notified as an occupational disease several times consecutively. 3. It is no rational value to assess how long before detection of the occupational disease the pacient was exposed to the risk, i. e. the action of the infectious agent. 4. Infectious and parasitic diseases as a rule do not lead to transfer of the workers from the work he performed so far. 5. The majority of diseases is cured completely. 6. The predominating part of patients is not entitled to damages for lost wages after termination of sick leave. 7. Enlistment of some diseases finto a certain category of occupational diseases is not necessarily unequivocal. 8. It is verv difficult to define more accurately the risk that the worker while doing a certain occupation will contract an infectious or parasitic disease. 9. Under conditions of the present legislativn fit cannot be rnled out that the number of infectious and parasitic diseases accepted as occupational diseases will increase many times even if the frequency of these diseases in the population does not change significantly. 10. In these diseases fit does not make sepse to use the term risk of occupational disease.
