Important COVID-19 Information from BASS Medical Group

This page reflects guidance shared in March 2020, early in the COVID-19 pandemic. Information about testing, masks, and treatment has changed since then. For current recommendations, visit the CDC or your local health department.

As COVID-19 began spreading globally in early 2020, BASS Medical Group prepared for potential community transmission in the United States, including Contra Costa County. Below is the original guidance provided at that time.

How can I protect myself and my family from COVID-19?

In early 2020, prevention focused on basic infection control practices similar to those used for influenza:

Wash your hands often with soap and water for at least 20 seconds
Use hand sanitizer with at least 60% alcohol if soap is not available
Avoid close contact with people who are sick
Avoid touching your eyes, nose, and mouth
Cover coughs and sneezes with a tissue, then wash your hands
Clean and disinfect frequently touched surfaces
Stay home when you are sick

These steps remain part of general infection prevention for respiratory illnesses.

Should I wear a mask in public?

At the time of publication (March 2020), public health guidance did not recommend masks for people who were well. Masks were reserved for:

Patients with respiratory symptoms
Caregivers and healthcare workers

This guidance later changed as more evidence became available and mask supply improved.

When should I contact a doctor about COVID-19?

Early guidance recommended contacting a healthcare provider if you:

Had recent travel to affected areas or contact with someone who had
Developed symptoms such as fever, cough, or difficulty breathing within 14 days

Patients were advised to call ahead before visiting a clinic or emergency department so providers could prepare appropriately.

What were the testing criteria in early 2020?

Testing in March 2020 was limited and coordinated through the CDC and public health departments. Criteria at the time included:

Fever or respiratory symptoms with known exposure to a confirmed case
Severe respiratory illness requiring hospitalization with recent travel
Severe pneumonia without another clear cause

Testing availability expanded significantly later in the pandemic.

Is there a vaccine for COVID-19?

At the time this article was published, there was no vaccine available. Vaccines were developed and became widely available later in 2020 and 2021.

Where can I find current COVID-19 information?

For up-to-date guidance, refer to:

Centers for Disease Control and Prevention (CDC)
California Department of Public Health
Contra Costa Health Services
