The disease is most prevalent in the cold weather. It dies down when the real summer heat sets in and people sleep more out of doors at night, thus lessening overcrowding. Of the 123 cases reported, 65 or 52.84% proved fatal. Ever since the severe outbreak of this disease, which occurred in 1917, a supply of serum, made at the Bacteriological Institute from the local strains of meningococcus, is kept in stock. This serum gives very good results when used early in the disease.
