III.—INFECTIOUS DISEASES.
§ 1.—DISCOVERY AND DIAGNOSIS.
It is well to know that unrecognised cases largely spread infectious diseases.
Discovery.—Mild cases of indisposition or disease excite no particular attention
or are attributed to other than the real cause by parents, guardians, or friends,
and are not submitted to medical examination. When cases of suspected
infectious diseases are discovered there is sometimes considerable difficulty and
delay in making an exact medical diagnosis in certain types of the diseases.
Here bacteriological and additional clinical examination arc brought to bear
upon doubtful types, and to check or confirm the diagnosis.
