When a person has died of epidemic cerebro- spinal meningitis, polio-myelitis, diphtheria or smallpox, no person except the undertaker and his assistants, the clergyman and others permitted by the director of public health shall enter the house until after the funeral and until after the warning placard has been removed. If the funeral is held elsewhere than at the last residence of the deceased, the funeral may be public; provided, that only those members of the immediate family may attend, who, in the opinion of the director of public health, are free from infection, and to whom he has given permission to do so. (Ord. 5869)
