acticed in the United States, Denmark, Great
Britain, and a few other countries, demonstrates in a striking manner the
efficacy of slaughtering and the futility of relying upon quarantine alone
to stamp out the disease.

Inoculation has been adopted in some countries in order to have the disease
spread quickly through the herds, and while this practice has undoubted
value where the disease is indigenous, it is not desirable in this country
and should not be adopted.

As a rule medicinal treatment with a view of curing affected animals is not
to be recommended under conditions prevailing in the United States, where
the disease has not become established, and the first object is to stamp it
out as quickly as possible. Even though most animals would recover, with or
without treatment, it would be practically impossible, while they were
being held for recovery, to prevent the spread of the infection to others.
The disease would be liable to spread faster than it could be cured. As
already pointed out, it has been found impossible to prevent absolutely the
spread of the contagion by the strictest quarantine alone, under the usual
farm conditions. In addition, the affected animals that have passed through
the disease may become a source of further infection as virus carriers for
weeks and months after they have apparently recovered, and are susceptible
of reinfection, as one attack does not confer permanent immunity.

_Foot-and-mouth disease in man._--Foot-and-mouth disease is primarily and
principally a disease of cattle; secondarily and casually, a disease of
man. It is transmissible to man through the eating or drinking of raw milk,
buttermilk, butter, cheese, and whey from animals suffering from
foot-and-mouth disease. It is also transmitted directly, though more
rarely, from the salivary secretions or other infected material which may
gain entrance through the mucous membrane of the mouth. It is doubtful
whether the disease can be transmitted to man by cutaneous or subcutaneous
inoculation, though it is probable that the infection may be communicated
if the virus directly enters the blood through wounds of any kind. Children
are not infrequently infected by drinking unboiled milk during the periods
in which the disease is prevalent in the neighborhood, while persons in
charge of diseased animals may become infected through contact with the
diseased parts or by milking, slaughtering, or caring for the animals.
