Our findings provide evidence to develop clinical guidelines that accelerate diagnosis and treatment of MOE to improve patient outcomes.

In patients with COVID‐19, certain medical conditions could result in poorer clinical outcomes. However, the prognostic role of hypothyroidism in COVID‐19 is still unknown. In the present retrospective study, we estimated the prevalence of hypothyroidism in COVID‐19 admitted patients in Tehran, Iran. Among 390 COVID‐19 admitted patients, 21 hypothyroid cases (5.4%) were found, in which nearly 90% were aged 50 years and older. Regarding the effect of hypothyroidism on COVID‐19 mortality, 60 (15.3%) of total patients and 4 (19%) of hypothyroid patients died, and no significant difference was found between the two groups.

The novel coronavirus SARS-CoV-2 infection is spreading worldwide, and there are many reports of acute respiratory distress syndrome caused by this infection. However, asymptomatic lung involvement has not been reported. We hereby present the case of a 44-year-old health-care worker, who was found to be infected with the SARS-CoV-2 virus after a CT-scan performed for an unrelated condition revealed a lesion in the lung field compatible with COVID-19 infection. His condition deteriorated initially, but eventually improved with supportive treatment and the compassionate use of antivirals and antimalarials and is now in a stable condition.
