• “Fun Friday in PreFab! Two DuThermX Mobile Carts ready to be shipped out! …#covid19solutions…#covid19prevention” [Published by your Twitter account on August 21, 2020, https://twitter.com/DubakElectric/status/1296916555683561472]

• “[P]roven best practices in identifying people with elevated body temperature is a key factor in mitigating the threat of illness. Recognizing the seriousness of the COVID-19 virus, Dubak’s world-class team of engineers started working on a safety solution in January 2020.” [Published on your website on April 28, 2020, https://www.duthermx.com/press-release-april]

The DuThermX is offered for sale in the United States without marketing approval, clearance, or authorization from FDA. Accordingly, your product is adulterated under section 501(f)(1)(B) of the Act, 21 U.S.C. § 351(f)(1)(B), because your firm does not have an approved application for premarket approval (PMA) in effect pursuant to section 515(a) of the Act, 21 U.S.C. § 360e(a), or an approved application for an investigational device exemption (IDE) under section 520(g) of the Act, 21 U.S.C. § 360j(g).

There is currently a global outbreak of respiratory disease caused by a novel coronavirus that has been named “severe acute respiratory syndrome coronavirus 2” (SARS-CoV-2). The disease caused by the virus has been named “Coronavirus Disease 2019” (COVID-19). On January 31, 2020, the Department of Health and Human Services (HHS) issued a declaration of a public health emergency related to COVID-19 and mobilized the Operating Divisions of HHS.2 In addition, on March 13, 2020, the Presidential declared a national emergency in response to COVID-19.3 Therefore, FDA is taking urgent measures to protect consumers from certain products that, without approval, clearance, or authorization by FDA, claim to mitigate, prevent, treat, diagnose, or cure COVID-19 in people. As described herein, you offer for sale a product that is intended for use in the mitigation, prevention, treatment, diagnosis, or cure of COVID-19 in people. We request that you take immediate action to cease the sale of such adulterated and misbranded products for the mitigation, prevention, treatment, diagnosis, or cure of COVID-19.

Use of telethermographic devices for the assessment of human body temperature can present potentially serious public health risks. Such risks may include, but are not limited to, the device incorrectly detecting a normal human body temperature when a person has an elevated temperature and incorrectly assessing a person to have an elevated body temperature when they do not. A person with an undetected elevate temperature who was subect to temperature assessment using a telethermographic device may, as a result, be less likely to adhere to infection prevention and control guidelines, such as social distancing and using personal protective equipment. These risks are more likely to be present where telethermographic devices scan multiple individuals simultaneously. Your website, https://www.duthermx.com/, includes statements that indicate that the DuThermX is intended to scan multiple individuals simultaneously, including:

• “How does DuTHERMX work?” In part, the answer states the DuThermX assess “16-40 people simultaneously.” [Published on your website’s “About COVID-19” webpage, https://www.duthermx.com/coronavirus-covid19]

• Chief Operating Officer Nick Dubak stated, “The DuThermX can scan 16 to 40 people at a given time.” [In a promotional video posted by Dubak Electrical Group on Vimeo, https://vimeo.com/412418206]

• “BODY DETECTION, UP TO 30 TARGETS.” [Published in the “DuThermX Product Overview PDF” available on your website, https://www.duthermx.com/systems]

• “BODY DETECTION, UP TO 16 TARGETS.” [Published in the “Technical Specifications” section of the “DuThermX Product Overview PDF” available on your website, https://www.duthermx.com/systems]

You should take action to address the violations cited in this letter. This letter is not meant to be an all-inclusive list of violations that exist in connection with your products or operations. It is your responsibility to ensure that the products you sell are in compliance with the Act and its implementing regulations. We advise you to review your websites, product labels, and other labeling and promotional materials to ensure that you are not misleadingly representing your product(s) as safe and/or effective for a COVID-19-related use for which they have not been approved, cleared, or authorized by FDA and that you do not make claims that misbrand the products in violation of the Act. Within 48 hours, please send an email to COVID-19-Task-Force-CDRH@fda.hhs.gov describing the specific steps you have taken to address these violations, using CMS # 613511 as reference. Include an explanation of each step being taken to prevent the recurrence of any violations, as well as copies of related documentation. Failure to adequately address any violations may result in legal action, including, without limitation, seizure and injunction.

FDA is advising consumers not to purchase or use certain products that have not been approved, cleared, or authorized by FDA and are being misleadingly represented as safe and/or effective for the mitigation, prevention, treatment, diagnosis, or cure of COVID-19. Your firm will be added to a published list on FDA's website of firms and websites that have received warning letters from FDA concerning the sale or distribution of COVID-19 related products in violation of the Act. This list can be found at https://www.fda.gov/consumers/health-fraud-scams/fraudulent-coronavirus-disease-2019-covid-19-products.
