The aim of this technical note is to propose a reliable, fast-adaptable and easy-to-use matrix that accurately classifies risk for contact tracing of healthcare workers with COVID-19 patients. The researchers have created a matrix with the support of the literature and their experience within the university hospital surveillance team. This matrix enables a detailed High / Medium / Low Risk classification of contacts of healthcare workers with COVID-19 cases, covering many different contact situations encountered in a university hospital. Three main headings have come to the fore in health worker contact risk classification: Differences caused by the ventilation of the environment: Indoors, well ventilated indoors, outdoors; direct contact or material sharing; aerosol generating procedure. The matrix is quickly adapted by surveillance team members and is easy to use.
