Table 2.

A summary table of early SARS-CoV-2 introductions into the Kenyan coast stratified based on the most frequent lineages.

Lineage	Introductions (approximate)	Percentage of sequences	Date of initial case	Source	Symptoms	Comments
A	15	6.14	4th April 2020	Household/After entry point	Yes	Returning from Dubai
B	5	1.96	13th April 2020	Household/After entry point	No	Returning from Dubai
B.1	8	74.44	17th March 2020	Local/surveillance	Yes	History of travel
B.1.1.119	4	0.98	13th May 2020	Border/Entry	No	Travel history to Tanzania
B.1.1.33	3	4.42	11th May 2020	Targeted testing	No	Detected during target testing
B.4	2	0.98	4th April 2020	Border/Entry point	No	Two sampled at port of entry, one with travel history to Zambia

Each row represents a major lineage and the date it was first observed from the sequence data and the suspected entry route (source) into the region, and whether the introductory case was associated with symptoms at the time of sampling. A detailed breakdown of all the lineages is shown in Supplementary Table 3.
