The 6 intravenously infected persons again contracted very serious typhus; 5 died.
Of the 6 infected intramuscularly, one person contracted medium typhus. The others had no serious complications, and were not hospital cases.
The surest means of infection to produce typhus in humans is, therefore, the intravenous injection of 2 cc. fresh typhus-infected blood.
