s in all, if there are others
who may contract measles in the house), and after leaving his room
should stay in the house a week longer. The principal danger after an
attack of measles is of lung trouble--pneumonia or tuberculosis
(consumption)--and the greatest care should be exercised to avoid
exposure to the wet or to cold draughts.

=GERMAN MEASLES= (_Roetheln_).--German measles is related neither to
measles nor scarlet fever, but resembles them both to a certain
extent--more closely the former in most cases. It is a distinct
disease, and persons who have had both measles and scarlet fever are
still susceptible to German measles. One attack of German measles
usually protects the patient from another. Adults, who have not been
previously attacked, are almost as liable to German measles as
children, but it is rare that infants acquire the disease. It is a
very contagious disorder--but not so much so as true measles--and
often occurs in widespread epidemics. The breath and emanations from
the skin transmit the _contagium_ from the appearance of the first
symptom to the disappearance of the eruption.

=Development.=--The period elapsing after exposure to German measles
and before the appearance of the symptoms varies greatly--usually
about two weeks; it may vary from five to eighteen days.

=Symptoms.=--The rash may be the first sign of the disease and more
frequently is so in children. In others, for a day or two preceding
the eruption, there may be headache, soreness, and redness of the
throat, the appearance of red spots on the upper surface of the back
of the mouth, chilliness, soreness in the muscles, loss of appetite,
watering of the eyes. Catarrhal symptoms are most generally absent, an
important point in diagnosis. When present, they are always mild.
These preliminary symptoms, if present, are much milder and of shorter
duration than in measles, where they last for four days before the
rash appears; and the hard, persistent cough of measles is absent in
German measles. Also, while there is sore throat in the latter, there
is not the severe form with swollen tonsils covered with white spots
so often seen in scarlet fever. Fever is sometimes absent in German
measles; usually it ranges about 100 deg. F., rarely over 102 deg. F. Thus,
German measles differs markedly from both scarlet fever and measles
proper. The rash usually appears first on the face, then on the chest,
and finally covers the whole body, in th
