Inform
“Inform” — timely reporting — is the third step of the “3I
system”. Thus, health care workers should promptly report the location
where a patient is found and diagnosed to the appropriate hospital
department, supervisor, and law enforcement officials. Clear reporting
schemes must be developed and alternatives must be available in the “3I
system”. Thus, when suspected cases of COVID-19 are identified in
China, direct online reporting is required within 2 hours, specimens are
collected for PCR analysis, and the suspected individuals are
immediately transferred to designated hospitals using safe
transportation. These procedures have greatly reduced the number of
missed cases.
