Furthermore, hospitals, especially those dedicated to chronic patients, as well as other communities that are not completely closed (such as school and work communities), are also at greater risk of small outbreaks that also affect healthcare professionals.
It is therefore necessary to carry out periodic checks on all healthcare professionals who work in healthcare facilities both to ensure their health and avoid the risk of possible contamination and to prevent the possible transmission of infection from the community to the hospital.
Another essential aspect to prevent infection in such facilities is the control of colonization in admitted patients.
Negativity from SARS-CoV2 should be carefully monitored in these patients prior to their placement in different departments.
On this basis, the study aims to determine the presence of SARS-CoV2 by monitoring with serial nasopharyngeal swabs carried out on healthcare professionals working within the facility and on new patients admitted.
In order to exclude the possibility of false negatives due to low viral load found in the early stages of infection (incubation time) or any exposure that may occur in the days following the execution of the swab, the study will i provide for the repetition of the swab examination, 3 times, at weekly intervals.
In order to verify the correspondence between the presence of IgM and IgG antibodies against the virus and the positivity to the swabs, the healthcare professionals and patients who undergoing nasopharyngeal swab will be previously subjected to the rapid antibody detection test (prick test for IgG and IgM).
