Immunitet:
"It is not clear today whether and how long the immune system maintains the memory of the coronavirus. The uncertainties are due to the fact that we have known this virus for a few months and that it takes time to check whether or not it remains immune and for how long. Furthermore, the success of a vaccine to reduce the spread of COVID-19 may depend on the duration of immunization. Research conducted so far on other coronaviruses, such as those that cause the common cold and that of SARS, seem to indicate the capacity of our immune system to track the infection. For some coronaviruses, immunity lasts just under a year, a period that could be acceptable to imagine future annual vaccination campaigns, as is already the case for influenza (which is caused by viruses other than coronaviruses). Immunity license In recent weeks in Italy and other western countries have spoken of serological tests as a means of providing an "immunity license", to distinguish who has already been infected and has passed the viral infection (even if asymptomatic) from those who are still exposed. In this way it could theoretically be guaranteed
MCOMST01-0 Press Release September 10, 2019 pag. A resumption of working activities and a lightening of restrictive measures, allowing those who are now immune to return to work and to move more freely.In reality, it seems difficult today to imagine that with serological tests an effective and reliable for this "immunity license": both because we do not yet know if and how much we remain immune after passing the coronavirus infection, and because the tests available so far do not offer completely satisfactory reliability margins (presence of false positives and false negative yet not fully ascertained) .Specificity of a diagnostic examination The specificity of a diagnostic examination is defined as the ability to correctly identify healthy subjects, that is, not affected by the disease or the condition that we intend to identify. If a test has excellent specificity, then the risk of false positives is low, that is, of subjects who, although presenting anomalous values, are not affected by the pathology that is being researched. The sensitivity of a diagnostic test is defined as the ability to correctly identify sick subjects, that is, those affected by the disease or condition that we intend to identify. If a test has excellent sensitivity, then the risk of false negatives is low, that is, of subjects who, although presenting normal values, are still affected by the pathology or condition they are looking for. In summary: HIGH SPECIFICITY = high probability that a subject healthy test negative; = low probability that a healthy subject will test positive; HIGH SENSITIVITY = high probability that a sick subject will test positive; = low probability that a sick person will test negative"
