LATENESS OF ARRIVAL FOR TREATMENT
It may be noted that the longest incubation period, which is
one hundred sixty-four days, among our cases of hydrophobia
was observed in a patient who reported for Pasteur treatment
forty-six days after being bitten by a dog that was suspected
of rabies (case 1607, serial case No. 1, Table 1). If in the
group of persons that received complete treatment (Table 1)
only the three cases that came for Pasteur treatment within the
first twenty-four hours after the bite are considered, the average incubation period for such cases would be seventy-four days,
which is even shorter than the incubation period of seventyseven days observed in case 9557, Serial No. 6, Table 4, who
reported two days after having been bitten by a dog not suspected of rabies and who received only four antirabic injections.
Although it is realized that there exist differences in the virulence of street virus as well as in the degrees of susceptibility and
resistance of individuals, the results, as pointed out above, are
rather disconcerting. However, the hydrophobia cases here
considered are too few to justify any conclusion.
LOCATION OF BITES
The classification recommended by the Paris Conference on
Rabies under the auspices of the League of Nations has been
followed in describing the location of the bites.
