It’s been several weeks since the virus COVID-19 showed up in Singapore. While there has been some evidence of community spread, the Ministry of Health has identified a few known clusters. This chart shows how the confirmed cases are related to each other.

Author’s update (22 February 2020): This visualisation will be updated on a regular basis as the situation unfolds in Singapore. It is also important to note that the Ministry of Health has clarified that #48 is not a super-spreader. The data visualisation has also been updated and tweaked to avoid giving this impression.

Author’s update (7 April 2020): It’s been slightly over a month since we started this story to track the connections among all of Singapore’s COVID-19 cases. On April 1, Singapore's cases went past the 1,000 mark. Just a few days later, the country saw it’s highest single-day spike at 120 new cases. It’s at this point that we’re unable to continue updating this story sufficiently and fully, as there is less information provided on individual cases by the Ministry of Health.

Moving forward, we will continue to keep a close eye on the situation. Stay tuned for more stories about the coronavirus and its impacts.
