Rising COVID-19 infection rates across much of the United States results in frequent changes to health guidance and requirements. As such, we all need to stay updated on changes in the places we live and work. Below are links to the COVID-19 pages for DC, Maryland, and Virginia. Please use these links to get the most up-to-date information available for the area where you live.


National updates regarding COVID-19 infection and vaccination are also available from the Centers for Disease Control and Prevention.


Office Policies & Procedures

Foxhall Medicine offers telemedicine options for Dr. Kristin Thomas’  patients, when possible. Dr. Joshua Yamamoto is not currently providing telemedicine options to his cardiac patients.   Our offices will remain open during the pandemic for medical visits and lab testing.  We have taken steps to reduce the chance of COVID-19 transmission in our office, and we screen all patients before their visit.

We ask that if you have any symptoms which are potentially due to a COVID-19 infection, you contact the office before you come in.  A complete list of these symptoms is available on the CDC website here:


All patients are expected to wear a mask or other protective face covering at all times while in the office. To maintain social distancing guidelines, we ask that you do not have anyone accompany you to your appointment unless their assistance is required.


COVID-19 Testing

COVID-19 testing requests for Dr. Thomas’ patients will be handled on a case-by-case basis. Referrals for testing will be made as needed.


COVID-19 IgG Antibody Testing

Antibody testing is available for Dr. Kristin Thomas-Yamamoto’s patients who think they may have had a COVID-19 infection at least three weeks ago. The antibody test may indicate that you have previously had a COVID-19 infection, but it cannot be used to diagnose a current infection.

Please contact the office if you are interested in having this test done.


COVID-19 Vaccines

The DC Department of Health has informed us that when a COVID-19 vaccine becomes available, it will be administered according to a risk stratification protocol. Health care workers and high-risk patients age 65 and older will be the first groups to receive the vaccine, and the health department will then provide rules on subsequent administration as they receive more doses of the vaccine.

At this time, the vaccine is only being administered through the Health Department. The vaccine is not currently available in private physician’s offices for use by the general public. If the vaccine does become available in our office, we will inform patients of the availability.
