Case-patient F (confirmed case) was a friend of case-patient A, who frequently visited case-patient A during case-patient A's illness.
Within 72 hours of the interview, we visited case-patients at home, where we observed household drinking water sources and storage containers, presence of water treatment products, access to toilet facilities, and the case-patient's handwashing technique.
While bringing the dead body back from hospital by bus, case-patient A's head rested on the thigh of case-patient F. Case-patient G (confirmed case) was the uncle of case-patient A who lived in the same village, and he never visited case-patient A during his illness.
They visited cases, on average, within 3 weeks of hospital discharge (for controls, hospital discharge of the corresponding case subject) and when possible, by the same interviewer.
Hospitalisations and mortality will be recorded by GPs at each planned visiting case report form.
Subjects who could not be classified to one race group using the plurality approach (0.5% of study visit case subjects) and those with missing data (0.02% of study visit case subjects) were classified as "other race/ethnicity" and "unknown race/ethnicity," respectively, and were excluded.
Subjects who could not be classified to one race group using the plurality approach, such as those participants that only report "other" race (0.5% of study visit case subjects) and those with missing data (0.02% of study-visit case subjects) were excluded.
Finally, a total of 91 participants (65%) mentioned visiting case managers at least once per two months, while the remaining 49 (35%) saw them less often or did not use their services.
(Project staff recruiting cases)" Following enrolment of a case, fieldworkers visited the case's community to enrol a matched 'healthy' control (a child whose parents answered 'Yes' to the question 'Is your child well today?').
He also visited two case management sites (Felege Hiwot Hospital and Gondar University Hospital) to gain additional understanding of the operational context and activities of the case management program.
