Case-based checklist for contact tracing

This checklist is for use by rapid response teams or community contact tracers

As soon as someone is suspected of infection

[ ] Quarantine the family and people living in the same household immediately.

[ ] Send immediate notice to people living in same complex, apartment, chaul or shelter.

[ ] Encourage the identified case to themselves send out a message to everyone in their contact list.

[ ] If the person wishes to stay anonymous till confirmed test results are back; contact list can be taken by the attending healthcare worker, and a message to everyone in the contact list can be sent out anonymously.

[ ] Ask the identified case to draw a route chart for past 14 days; encourage the case to remember interactions with retail shop owners; relatives; police staff; bus, auto or cab drivers; service providers such as delivery guys; hawkers; vegetable vendors; healthcare workers.

Communication to the first and second order contacts

[ ] Remember that the identified case has a right to medical anonymity.

[ ] Inform the first and second-order contacts only the fact that they are suspected of an infection and not who they got the infection from.

[ ] Send a team of doctors and paramedics to counsel the case; contact trace their contacts and collect samples for testing.

[ ] Counsel the suspected case to encourage those who may have been in contact with them to seek medical care.

[ ] Provide guidance on home isolation, telemedicine numbers and emergency service numbers.

[ ] Create a active monitoring chart for the suspected cases where they can record their symptoms. The same can be tracked by Rapid Response Teams.

[ ] If the identified contact is demonstrating severe symptoms; immediately transfer to an isolation ward.

[ ] Do not wait for test results to move symptomatic cases to isolation ward as it would amount huge risk to the individual and to those who may come in contact with the person.

When a health care professional is suspected of infection

[ ] Immediately lockdown the hospital/clinic where the case was identified.

[ ] Record route history of the doctor/nurse/sanitation staff to identify the source of infection.

[ ] Test all associated healthcare workers who were in contact with the source. Mandate 14-day home isolation for healthcare workers, start active monitoring.

[ ] Quarantine staff who were present in the hospital at the same time as source. Enable self-monitoring for quarantined staff.

[ ] Quarantine patients who were present in the hospital at the same time as source. Start active monitoring for quarantined staff.

[ ] Repeat contact tracing exercise for the source.

[ ] Redo infection control training and infection control audit at the hospital.

When a essential services provider or a response team member is suspected of infection

[ ] Route chart is most important here. They may not remember all interactions so identify nodes on the route chart. Nodes are places where a stop may have been made by the identified case.

[ ] Interact with everyone in 1 km radius of the identified node. eg: 1 km around the vegetable market where vendor was supplying; or 1 km around the petrol pump where the person may have stopped.

[ ] If response team member is suspected; screen all the patients who were previously screened by the response team member.
