From the Humboldt County Joint Information Center:

How do we #FlattenTheCurve and #SlowTheSpread of COVID-19? One tool we use at Humboldt County Public Health is contact tracing. Public Health investigators have been working tirelessly for months to trace the contacts of known COVID-19 patients. With their diligent work, we have been able to slow the spread here in Humboldt County. We will continue to work together with our community to do everything we can to flatten the curve.
