The exact extent to which a person with SARS CoV2 infection can transmit the infection to other is uncertain. The potential for SARS-CoV-2 transmission begins before the onset of symptoms and decreases thereafter. Infected people are more likely to be contagious in the early stages of the disease, when the level of viral RNA in the upper respiratory tract is highest. The duration of viral RNA clearance is variable and may increase with disease severity. In some people, viral RNA can be detected in the respiratory tract a few months after the initial infection. However, detectable viral RNA does not always indicate the presence of the infectious virus and there appears to be a threshold below which the infectivity is unlikely. Prevention and limitation measures are essential in both healthcare and the community. Medical personnel must apply additional precautions to protect themselves and prevent the transmission of the disease during medical care. This paper aims to study the incidence of the IgM and IgG antibodies anti-SARS CoV2 in healthcare professionals. The determination of antibodies was made on request, both to see the immunization of people who went through the disease and to evaluate asymptomatic personnel (they came in direct contact with confirmed people).
