Emerging data suggest that healthcare workers (HCWs) may be at increased risk of Covid-19 in break rooms when consuming food or when in the presence of others without a mask.1-4
In a study of over 700 HCWs screened for SARS-CoV-2 by PCR at a university hospital, staying in the same personnel break room as an HCW without a medical mask for more than 15 min and consuming food within 1 meter of an HCW were significantly associated with SARS-CoV-2 infection.1 Consumption of food in break rooms by personnel was thereafter “forbidden” in this facility. Interestingly, 28% of infected personnel in this study lacked symptoms at the time of testing.
A recent outbreak at a Boston hospital involving both patients and HCWs months after institution of strict infection control measures (including universal masking of visitors and HCWs and PCR testing of all patients on admission) traced the outbreak to a variety of factors, including HCWs eating in crowded work rooms.2,3
A CDC study of risk factors among adults 18 years or older with Covid-19 in the community identified dining at a restaurant as significant risk factors for Covid-19.4
Transmission of SARS-CoV-2 during eating or drinking is not surprising because masks cannot be effectively worn during food consumption. Combine eating or drinking with talking, laughing and suboptimal ventilation system and we have all the elements of perfect storm for transmission of Covid-19 during food breaks.
Bonus Pearl: Did you know that, in addition to dining at a restaurant, patients with Covid-19 without known close contact with infected persons have reported higher likelihood of going to bar/coffee shop? 4
