Following diseases require isolation to break transmission except:
Isolations-Separation, for the period of communicability the cases of a communicable disease.

- Duration of isolation is determined by the duration of communicability of the disease and the effect of chemotherapy on infectivity.
- Period not longer than longest usual incubation period of the disease for which contact with non exposed ones is prohibited. It is applied to such healthy persons who have come in contact with the case of a communicable disease.
