DIPTHERIA


iae), the Klebs-Loeffler bacillus.
5. Period of Communicability.
Until virulent bacilli have disap-
peared from the secretions and the
LESSONS. The persistence of the ba-
cilli after the LESSONS nave healed
two weeks. In most cases, the
bacilli disappear in four weeks. In
exceptional cases virulent bacilli re
main in the throat and discharges
for from two to six months.
o. Methods of Control
(a) The infected individual and
his environment-
i. Fiacard required. Recognition
of the disease by clinical symptoms
with confirmation by meteorological
examination of discharges.
Q. Isolation. Until two cultures
from the throat and two from the
nose, taken not less. than "a hours
apart, fail to show the presence of
diptheria bacilli. Isolation may be
terminated If persistent diptheria
bacilli prove v%irulent. Where termi-
nation by culture is impracticable,
cases may be terminated with fair
safety as a rule 16 days after onset
of the disease.
FAVUS
l.. Infectious Agent. (Achorion
schoenleinii).
q. Source of Infection. Lessons
of skin. particularly on the scalp.
8. Mode of Transmission. Direct
contact with patient, and indirectly
through toilet articles.
g.. Methods of Control.
(a) The infected individual and
his environment
1. No placard.
g.. Isolation. Exclusion from
school and other public places until
the LESSONS have healed.
GERMAN MEASLES
(Rubella)
/. Infectious Agent. Unknown.
2. Source of Infection. Secre-
ton of the mouth and possibly of
the nose.
L. Placard required.
3. Isolation. Exclusion of the
infected person from school and
from other public places and from
contact with n-on-immune persons,
for eight days from date of onset.
GoNORRHEA
1. Infectious Agent .Gonococcus.
(Neisseria gonorrhoeae).
A.. Incubation Period. One to
eight days, usually three to five
days.
5. Period of Communicating.
AS long as the %gonocuccus persists
in any of the discharges, whether
the infection be an old or a recent
one.
L. No placard. except when pa
tient violates directions of health
officer and professional attendant.
INFLUENZA
1. Infectious Agent. Undeter-
mined.
2. Source of Infection. Probably
discharges from the mouth and nose
of infected persons and articles
freshly soiled with such discharges.
5. Period OF Communicability.
Undetermined. apparently during the
febrile period, or at least for seven
days from onset of clinical symp-
toms.
6. Methods of Control.
(a) The infected individual and
his environment
/. Placard required.
MEASLES
2. Source of Infection. Buccal
and nasal secretions of an infected
individual.
a. Incubation Period. About ten
days.
S. Period of Communicability.
During the period of catarrhal symp-
toms and until the cessation of alb
normal mucous membrane secretions
minimum period of nine days;
from four days before to five days
after the appearance of the rash.
6. Methods of Control.
(a) The infected individual and
his environments
/: Placard required.
2. Isolation. During period of
communicability.
3. Quarantine. Exclusion of non
immune contacts from school and
other public gatherings, and from
contact with children. for fourteen
days from date Of last exposure.
MENINGoCoCCUS MENINGITIS
/. Infectious Agent. Meningoc-
occu; (Neisseria intracellularis).
S. Period of Communicability.
During the clinical course of the
disease and until the specific organ
ism Is no longer present in the
nasal and mouth discharges of the
patient. The same applies to healthy
carriers so far as affects persistence
of infectious discharges.
6. Methods of Control.
(a) The infected individual and
his environment
l.. Placard required.
2. Isolation of the infected per-
son or carrier until the naso-phar-
iynx is free from the infectious agent
as demonstrated by laboratory test,
where such facilities are available,
or for two weeks from date of on
set, or until the temperature has
been normal for one week.
3. Quarantine of contacts until
demonstrated not to be carriers.
where laboratory facilities are avail
able, or for ten days from date of
last exposure.
