- When the disease/exposure causing the outbreak is unclear, in the first hours or days following an alert, use the T0 (T”0” stands for time 0) to collect patient data.
When there is no specific case investigation form to investigate the event available, because of other than infectious hazards or new/emerging disease.
SYNDROME Case investigation form

EXPOSURE case investigation form

T1 - Unknown disease case investigation form
