April 18, 2020 - Case Count Remains at 52

707-441-5000 ; ; Monday-Friday 8am to 7pm ; Saturday 10am to 5pm

No additional cases of COVID-19 were confirmed Saturday. The total case count remains at 52.

Humboldt County Health Officer Dr. Teresa Frankovich said this slower period in new cases affords residents the opportunity to intensify their preparedness efforts. “As I mentioned yesterday, with the first county-level state modeling received this past week, we are able to review their perspective on COVID-19 projections and relate it to our on-the-ground efforts,” she said. “We will be sharing that information this coming week and talking about what it can and cannot tell us about what may lie ahead.”

The following information is based on the most recent data available for all confirmed cases:

  • Contact to a Known Case: 23
  • Travel-Acquired: 20
  • Community Transmission: 8
  • Under Investigation: 1

For the most recent COVID-19 information, visit or Local information is available at or during business hours by contacting or calling 707-441-5000.

What do the numbers mean? 

  • Total new positive cases—the number of test-confirmed positive cases since the previous report.
  • Total number of positive cases—the number of test-confirmed positive cases since the pandemic began, including people who have recovered from the illness.
  • Total number of hospitalizations—total number of COVID-positive people hospitalized since the pandemic began, including people who have been released.
  • Total number of people tested by Public Health Lab Laboratory—number of people whose sample was tested by the Humboldt County Public Health Laboratory.
  • Total number of people tested by all other sources—total number of tests performed by the Centers for Disease Control and Prevention (CDC), the California Department of Public Health (CDPH), LabCorp and Quest Diagnostics. Non-local labs have a slower turnaround time than our local lab, primarily due to the time it takes local samples to be shipped elsewhere for testing.
  • Public Health Lab test capacity—the approximate number of testing kits that are complete and ready to be administered. This number is decreased by testing and increased as additional supplies are acquired.
  • Public Health Lab turnaround timethe estimated amount of time it takes per testing run. Each run can include up to 20 samples; multiple batches can be run each day.
  • Transmission data
    • travel-acquired—nationally, internationally or regionally
    • contact to known case—an individual found to have been in direct contact with someone who tested positive for the virus
    • community transmission—spread without travel or known contact to any other positive case
    • under investigation—positive case whose means of transmission has not yet been determined.

Notes on patient and demographic data

To protect the identity of people with COVID-19, their specific location of residence will not be disclosed. The Humboldt County Public Health Branch is legally responsible for protecting personal health information, including residence address, specific age, recent travel, the identities and locations of any contacts, the provider of medical treatment, the course of illness and any other information that might identify an individual with or exposed to the virus unless it serves the interests of public health to do so.

Although we understand it is of interest to residents, providing location and demographic information to the general public does nothing to slow the spread of illness. Humboldt County is experiencing untraceable person-to-person transmission, also known as “community spread,” and there is no place that can be considered safe. To reduce your chances of acquiring or spreading COVID-19, avoid travel, wash your hands, keep yourself and your environment clean, follow the shelter-in-place order, and do not leave home for any reason unless it is absolutely necessary to do so.

The following case information is provided daily Monday through Saturday:

  • New positive cases
  • Total positive cases to date
  • Total hospitalizations to date
  • Total Public Health Lab tests to date

  • Public Health Lab test capacity, total and daily, and estimated turnaround time
  • Transmission data

    • soon to be represented instead by region after minimum thresholds of positive cases per region have been reached
  • Gender
  • Mean age
