The same cannot be said of the Borah community, for, on the outbreak of the
epidemic, the whole sect was taken in hand by the headman and removed into
segregation huts outside the city and there kept in insolation. This and the fact that
571 out of a community of 1,500 were inoculated with Yersin's preventive serum
undoubtedly account for the low rate of mortality.
To the Khatri and Khoja castes, both numerically small, to a large extent the
same remarks apply.
The mortality also varies considerably with the day of the disease on which the
patient is admitted.
Of 100 non-inoculated cases from the Brahmapuri Hospital, from May 25th to
June 2nd, admitted-
First    day  ...      ...       ...82 per cent. died.
Second    "   ...      ...        ..66    "        "
Third     "   ...      ...         .95    "        "
Thus the third day is far the most fatal, and this experience has been endorsed at
all the other hospitals.
The general Mahomedan Hospital received patients from the city and the village
of Salaya where the sea-faring community exists, under much the same conditions as
the Hindoos in the city, except that there is less overcrowding, more light, and air.
Treatment.
Treatment-
(a) Preventive.
(b) Curative.
(a) Preventive methods consist chiefly in removal" of the conditions which
favour the development of the disease and, having become established, the limitation
of its spread.
The conditions  favourable  to  the  development of plague  have already been
enumerated.
With regard to the limitation of its spread, the chief considerations are-
(a)  Isolation of the sick under the best circumstances.
(b)  Disinfection  of all articles of clothing or bedding used by the patient and
of the house in which he has lived.
(c)  Preventive inoculation of serum antipesteux prepared by the Pasteur Institute.
On account of the brief period of immunity conveyed by the usual dose of 10 cc,,
it is extremely difficult to prove the value of this method of treatment.
It has not been found possible to inoculate whole communities (every ten days).
The communities object, in which case it is not accurate to ascribe the absence of
plague to the immunising effect of the serum ; nevertheless, it is an extraordinary
fact that, out of 721 persons who have been inoculated once only, up to the present not
a single case of plague has developed. These cases have all been registered and are
composed of different castes living in different places.

Men of Borah community ...     ...     ...         ...	380
Children    "    "             ...      ...      ...    ...	191
Men, women and children of Muska village    		...	110
Men, women and children of Bada village (16 miles	
from Mandvi)     ...         ...       ...      ...     ...	40

It also seems clear that immunisation conveyed by the preventive serum becomes
rapidly less from tenth day to the twentieth day, when it may be said to be exhausted.
Sepoy Jayanak Tulnak, who died from plague, had been inoculated 20 days previously
to the attack.
(b) Curative-(a) General, (b) Special.
