In California we saw a very quick increase of COVID 19 cases, partly because we have such a high population. In my efforts to monitor the situation in my home state I have been following this Los Angeles Times article where they try to track the known cases and deaths.

One of my personal favorite sections is the 'cumulative cases by county' where they created an interactive data table that highlights different counties in the state. This in-depth research helps residents understand how all areas, including their own, are being affected.
