Tuolumne Covid-19 Cases by Age
Tuolumne Covid-19 Cases by Age
  • The no-cost state testing site is open at the Calaveras County Fairgrounds Tuesday – Saturday 7am to 7pm. Appointments can be scheduled ahead of time at: Appointments are strongly recommended as walk-ins are extremely limited.
  • Wondering about face shields? People who are exempted from wearing a face covering due to a medical condition, who are employed in a job involving regular contact with others should wear a non-restrictive alternative, such as a face shield with a drape on the bottom edge, as long as their condition permits it. Here’s what that looks like. Using a face shield without an apron or using a smaller, partial shield is inadequate as it still allows for droplets to escape from the wearer.
    They should only be worn by those who meet the state medical exemption and the CDC does not recommend use of face shields for normal everyday activities or as a substitute for cloth face coverings. A link to the state face covering document is here. More helpful info about cloth face coverings:
  • In regard to antibody testing, Public Health cannot speak to the accuracy of the tests being offered by commercial laboratories and we are not currently making a recommendation for the testing. Individuals should contact their healthcare provider to determine if testing is recommended. It is important to note that the relationship between antibody presence and immunity is not currently known. This means that if a person tests positive for antibodies, it does not necessarily mean that the person is immune to COVID-19. It is unknown if people who test positive for COVID-19 antibodies are at risk of infection. Also, antibody tests have not been shown to definitively diagnose or exclude SARS-CoV-2 infection.

It is important that people continue to follow prevention guidelines to help prevent the spread of COVID-19, including:

  • Practice physical distancing at all times. Keep 6 feet space between yourself and others who are not part of your household. Stay in your household bubble!
  • Wear a face covering in public.
  • Wash your hands thoroughly and frequently.
  • Avoid gatherings of any size with people who are not part of your household.
  • Stay home if you are sick.
  • Avoid unnecessary travel, and limit your outings to essential tasks.
