In-home COVID-19 tests without contact tracing is ‘bad public health’

Cornell University
22-Apr-2020 11:10 AM EDT, by Cornell University

The Food and Drug Administration approved the first in-home test for the novel coronavirus, which will allow patients to swab their own nose using a testing kit sent LabCorp and mail it in an insulated package back to the company. The test will be available in most states.

Isaac Weisfuse, a medical epidemiologist at Cornell University with more than 25 years of experience in public health at the local and national levels, says that while in-home testing will help reduce the potential risk for transmission, there is still a critical need for contact tracing.

Weisfuse says:

“The availability of a new in-home COVID-19 test will expand testing options and reduce the need for travel to medical appointments, saving time and the potential risk of transmission. The test will be initially be offered to exposed or symptomatic health care workers and emergency personnel only. Consumers need to be aware of some limitations of the test. For example, it will test for active infection in order to establish a diagnosis, but not to document resolved prior exposure, which would require an antibody test. There is also a possibility of both false positives and false negatives and is therefore considered less reliable than the standard test administered by health care personnel.  

“LabCorp should work with public health authorities to emphasize the critical need of contact tracing for anyone who tests positive. Any positive test without contact tracing is bad public health because it misses an opportunity to reduce the spread of the virus. The test carries a $119 out of pocket cost. Even with subsequent reimbursement, given the current economic situation, this initial cost may put it financially out of reach many who could benefit, and ultimately limit its use.”

COVID-19 Pandemic Drinking: Increases Among Women, Black Adults, and People with Children
Research Society on Alcoholism

Risky drinking has been a public health concern in the U.S. for decades, but the significant increase in retail alcohol sales following COVID-19 pandemic stay-at-home orders in particular raised red flags for alcohol researchers. New research has assessed changes in alcohol drinking patterns from before to after the enactment of stay-at-home orders. These results and others will be shared at the 44th annual scientific meeting of the Research Society on Alcoholism (RSA), which will be held virtually this year from the 19th - 23rd of June 2021 due to the COVID-19 pandemic.
