Prevalence of Dysosmia and Dysgeusia in People with COVID-19 at a Tertiary Care Hospital

Abstract

The coronavirus disease 2019 is an infectious disease that affects the sensation of smell and taste. This descriptive study aimed to assess the prevalence of dysosmia and dysgeusia in 400 people infected with COVID-19 who came for screening at Ramathibodi Hospital, Bangkok. Data were collected from medical records. Instruments for data collection included the demographic data form and health data form, such as the history of infection risk factors, testing results for coronavirus 2019, symptoms related to the sense of smell and taste, other abnormal symptoms, and medical conditions. The data were analyzed using descriptive statistics, including frequency, percentage, mean, and standard deviation. The study results found that a sample of 400 people had an average age of 41.54 years, with the majority being 221 females (55.25%). The most significant risk factor for COVID-19 infection was contact or close contact with patients confirmed to have the disease in 316 cases (79.00%). The history of high blood pressure was kbserved in 79 cases (19.75%). Dysosmia was observed in 99 cases or 247.5%; and the percentage of cases with dysgeusia was 11.50% (46 cases). The number of cases with both symptoms was 35 (8.75%). The study results demonstrated that dysosmia and dysgeusia are quite common symptoms in people infected with COVID-19. Therefore, public health personnel can apply the study results as guidelines for evaluating people at risk of developing COVID-19 and will continue monitoring their long-term symptoms.
