    The risk of infection among contacts of cases of pneumonic plague varies with intensity of exposure and possibly with environmental factors. During an outbreak of pneumonic plague in Madagascar, investigators measured serum F1 antibodies among contacts and estimated that the secondary infection rate was % (Ratsitorahina ).   SUMMARY Following the discovery of a plague-like disease, due to B. tularense, by McCoy and Chapin in California, W.
