The total number of infected subjects was 13.
The variable diarrhea had a denominator of 7 due to missing data among infected subjects.
The variable “overall symptoms” was defined as a subject with at least one symptom, not including fever. To be classified as an overall symptom, fever had to be associated with at least one other symptom. For example, a subject with fever and headache was classified as being overall symptomatic; however, a subject with only fever was not considered overall symptomatic.
A WBC shift was defined as an increase in granulocyte production with an abnormal granulocyte count, i.e., >72% of the total WBC count.
