Persistently positive PCR after COVID-19. How to diagnose reinfections? [Spanish]

Persistence of a long-term positive polymerase chain reaction (PCR) test in patients with severe coronavirus-associated respiratory syndrome may interfere with the diagnosis of reinfections, causing false positives of the disease, with the potential implications to determine the need for isolation and, consequently, for Public Health. In these field notes we present the experience of a patient with positive PCR of eight months of evolution to which an erroneous diagnosis of COVID-19 reinfection was made due to a gastrointestinal disease, resulting in a Campylobacter jejuni infection.

[Ethical dimensions of prevention and planning in assisted-living facilities during the SARS-CoV-2 pandemic (Covid-19): a public health emergency.]

The SARS-CoV-2 pandemic (Covid-19) has had a major impact on residents of assisted-living facilities. While it is plausible that the characteristics of these patients and their special clinical fragility have contributed to their greater vulnerability to infection, other related factors cannot be ruled out, such as the quality of management at these centers and the lack of planning for actions taken before and during the health crisis. Both aspects pertain to the field of public health, where the ethics of the common good conflicts with the autonomy of the individual.
