Contact tracing as an essential prevention tool for the spreading of COVID-19 among healthcare workers

AbstractHealthcare workers, since the beginning of the COVID-19 pandemic, have been universally recognized as especially susceptible, with infection risks higher than the general population. Therefore, it is important to apply infection prevention and control measures in healthcare institutions to limit infections associated with the provision of healthcare services. In this contest, contact tracing, in fact, is an essential public health measure to fight the COVID-19 pandemic, with active case finding and testing, and physical distancing. Globally, new weekly cases and deaths are decreased, but WHO emphasizes that cases and deaths should be interpreted with caution because several countries have been progressively changing COVID-19 testing strategies, resulting in lower overall numbers of tests performed and consequently lower numbers of cases detected. Health personnel, therefore, work at a high-risk department and this has been associated with a 2.13 times higher risk of COVID-19 compared to the general departments of any hospital and, if the healthcare workers had inability to continue working and if there was the possibility of hospitals turning into sources of infection, it could be an interruption in healthcare services. A coordination with the system of surveillance is important that remains in the hospital in order to fight COVID-19 and help restructure the response in the light of detected transmission and guarantee safe hospital care.
