The First Few X (FFX) Cases and contact investigation protocol for 2019-novel coronavirus (2019-nCoV) infection
This protocol has been designed to investigate the First Few X cases (FFX) and their close contacts. It is envisioned that the FFX 2019-nCoV investigation will be conducted across several countries or sites with geographical and demographical diversity. Using a standardized protocol such as the protocol provided here, epidemiological exposure data and biological samples can be systematically collected and shared rapidly in a format that can be easily aggregated, tabulated and analyzed across many different settings globally for timely estimates of 2019-nCoV infection severity and transmissibility, as well as to inform public health responses and policy decisions. This is particularly important in the context of a novel respiratory pathogen, such as 2019-nCoV.
Symptom diaries should be provided to each close contact, for them to record the presence or absence of various signs or symptoms for a minimum of 14 days after the administration of the initial contact questionnaire (Form B1 in the app). The symptom diary template provided below is generic. In the context of a new virus with uncertain clinical presentation and spectrum, symptom diaries may be broadened to include vomiting, diarrhoea, abdominal pain, etc., as relevant, and may be altered to include symptom data for longer than 14 days. In the event the contact develops any of these symptoms, ask him/her to inform your local public health team.
Using the WHO original protocols, Dimagi's team of software engineers and implementation specialists built this into a CommCare application. Expand the box below for a high-level diagram of the CommCare application workflow.
