Fig. 1. — Timeline of close contacts, illness onset, polymerase chain reaction (PCR) test or computed tomography (CT) and hospitalisation for family clusters a, b and c during 15 January 2020 and 9 February 2020. Patient numbering is based on kindred relationship. (a) Index case A (G0) had dinner with four cases A1–4 (G1). It is noticed that the time of illness onset of case A1 (G1) was earlier than that of index case A (G0); (b) Index case B (G0) had close contact with four cases B1, 2, 10 and 11 (G1). B2 (G1) transmitted the infection to six cases B3–6 and 9 (G2) and B11 (G1) transmitted the infection to cases B12–14 (G2). B6 (G2) transmitted the infection to two cases B7–8 (G3); (c) Index case C had a party with six cases C1–6 (G1). Case C6 (G1) transmitted the infection to three cases C7–9 (G2), and case C5 (G1) transmitted the infection to case C10 (G2).

Symbols (meal , vehicle , live together , cleaning ): date of close contact; symbol (facing down arrow ): date of symptom onset, or PCR test/CT scan; symbol (red cross ): date of hospitalisation. Behind red cross symbol is clinical type at the admission.
