(A) Epidemic curve of COVID-19 in Malaysia and time course of reported total cases, Tablighi-associated cases, and lineages based on 115 Malaysian sequences, from the first reported case on 25 January to 20 September 2020. The Tablighi Jamaat gathering in Kuala Lumpur is labelled as “mass gathering, KL”. The different phases of lockdown are shown, comprising the movement control order (MCO), conditional movement control order (CMCO) and recovery movement control order (RMCO). (B) Time course of global reported lineage B.6 SARS-CoV-2 sequences available in the GISAID database (as of 20 September 2020). The timescale of the horizontal axis is the same as (A). Countries with fewer than 5 lineage B.6 sequences are included in “others”, comprising Brazil (1), China (3), France (1), Gambia (1), Guam (3), Hong Kong (1), Iceland (1), Jamaica (1), Japan (4), Kenya (1), Myanmar (1), New Zealand (3), Oman (4), Portugal (2), Saudi Arabia (2), Senegal (1), Sierra Leone (1), South Africa (4), South Korea (2), Slovenia (1) and Turkey (1). (C) The percentage rates of lineage B.6 sequences over total available complete sequences (in brackets) from each country available at GISAID as of 20 September 2020. Asia Pacific countries are colored grey.
