Asymptomatic SARS-CoV-2 infection in an unvaccinated 97-year-old woman: A case report.

Coronavirus disease (COVID-19) is an infection caused by the newly detected coronavirus, SARS-CoV-2. The majority of individuals will exhibit mild to moderate illness. Older individuals, and those suffering from co-existing diseases have a greater probability of experiencing a serious illness. Moreover, elderly patients have higher mortality rates than younger patients, especially those who are unvaccinated. Asymptomatic infection is mostly observed in individuals who are younger, as younger patients are more likely to exhibit a stronger immune response to the infection; aging is characterized by the decline immune function. In this article, a rare case of an unvaccinated 97-year-old woman is described who was admitted to Laiko General Hospital due to altered levels of consciousness, hypotension and a hematoma of the thoracic region, and tested positive for SARS-CoV-2 nucleic acid in a nasopharyngeal specimen and positive for IgG antibodies against the SARS-CoV-2 spike protein without a history of consistent manifestations, indicating a past asymptomatic infection.
