Part II GERM DISEASES BY KENELM WINSLOW CHAPTER I =Contagious Diseases= _Scarlet Fever--Symptoms and Treatment--Precautions Necessary--Measles--Communicating the Disease--Smallpox--Vaccination--How to Diagnose Chickenpox._ =ERUPTIVE CONTAGIOUS FEVERS= (_including Scarlet Fever, Measles, German Measles, Smallpox, and Chickenpox_).--These, with the exception of smallpox, attack children more commonly than adults. As they all begin with fever, and the characteristic rash does not appear for from one to four days after the beginning of the sickness, the diagnosis of these diseases must always be at the onset a matter of doubt. For this reason it is wise to keep any child with a fever isolated, even if the trouble seems to be due to "a cold" or to digestive disturbance, to avoid possible communication of the disorder to other children. While colds and indigestion are among the most frequent ailments of children, they must not be neglected, for measles begins as a bad cold, smallpox like the _grippe_, and scarlet fever with a sore throat or tonsilitis, and vomiting. By isolation is meant that the sick child should stay in a room by himself, and the doors should be kept closed and no children should enter, nor should any objects in the room be removed to other parts of the house after the beginning of its occupation by the patient. The services of a physician are particularly desirable in all these diseases, in order that an early diagnosis be made and measures be taken to protect the family, neighbors, and community from contagion. The failure of parents or guardians to secure medical aid for children is regarded by the law as criminal neglect, and is subject to punishment. Boards of health require the reporting of all contagious diseases as soon as their presence is known, and failure to comply with their rules also renders the offender liable to fine or imprisonment in most places.
