CHRYSANTHAKOPOULOS, Nikolaos. Histopathology and pathogenesis of coronavirus disease 2019 (COVID-19). Iberoam J Med [online]. 2020, vol.2, n.3, pp.230-234.  Epub Feb 12, 2020. ISSN 2695-5075.  https://dx.doi.org/10.5281/zenodo.3823859.

A severe pandemic of CoronaVirus disease 2019 (COVID-19), according to World Health Organization (WHO), appeared in China in December 2019, and spread rapidly. The majority of the patients had mild symptoms and good prognosis after recovery; however some patients developed severe inflammatory reaction and passed away from multiple organ complications. The novel coronavirus, Severe Acute Respiratory Syndrome Corona Virus 2 (SARS-CoV-2) is a beta-coronavirus and is similar with the Severe Acute Respiratory Syndrome Corona Virus 1 (SARS-CoV-1) and the Middle East Respiratory Syndrome Coronavirus (MERS-CoV). SARS-CoV-2 and -1 have the same host receptor, the angiotensin-converting enzyme 2 (ACE2). The pathogenesis of SARS-CoV-2 infection in humans remains unclear. The immune response is essential to control and reduce SARS-CoV-1 and -2 infections, however, irregular and exaggerated immune responses may lead to the immunopathology of the disease and the lung lesions. This article presents the immunological features of SARS-CoV-2 infection and its potential pathogenesis based on the recent observations of the International literature.
