Hello from the Fun Math Club!

With the onset of the Coronavirus pandemic, I find myself in the office (my home) with time to do things I haven’t had time to do before. Although a blog was very low on my to-do list, I decided to start one so that I can eventually talk about Fun Math Club plans, thoughts, and other math-related topics. However, the primary motivation for starting this blog arose a few days ago. I was trying to find out how fast COVID-19 was spreading in our community, Santa Clara county, but I couldn’t find a source on the web that historically tracked the data. So I searched for posts over the last month and pieced together data starting from Feb 28. The chart below shows the status as of today, Mar 22.

The projection is based on the most recent 5-day moving average of percent daily increase in COVID-19 cases (as reported by the County of Santa Clara Public Health Department). This graph is a grim reminder of the absolute urgency to flatten the curve. If you’re not convinced by the graph above, consider this: at the current rate of increase by end of April, there would be more than 50,000 cases in Santa Clara county. On the brighter side, the data may also overstate the growth rate due to a lack of testing. I certainly hope so.

Since I haven’t seen this graph for Santa Clara county, I decided to start my blog to provide a medium to share the graph on a regular basis (daily or as time/memory permits) so that others can see how our community is doing fighting the pandemic spread.

I end today’s post with two pleas and a wish: follow shelter-in-place guidelines, social distance, and stay healthy.
