Malaysian COVID-19 Anosmia Study (Phase 2) - A Nationwide Multicentre Case-Control Study

Summary

The Malaysian COVID-19 Anosmia Study is a nationwide multicentre observational study to investigate the prevalence and characteristics of olfactory and gustatory/taste disturbances in COVID-19 infection in Malaysia, and to evaluate the predictive value of screening for these symptoms in COVID-19 infection.

This study consists of two phases: the first phase is a cross-sectional study and the second phase is a case-control study. The case-control study is described here (the cross-sectional study is described in a separate ClinicalTrials.gov record).

Patient-Reported Online Questionnaire on Olfactory & Taste Disturbances

This is an online patient-reported questionnaire that examines the presence or absence of olfactory and taste disturbances, the onset of olfactory and taste disturbances in relation to other COVID-19 symptoms, and the temporal evolution of the severity of olfactory and taste disturbances. The occurrence of ear symptoms in COVID-19 infection will also be evaluated in this questionnaire as a secondary outcome. The questionnaire will also have questions relating to the patient's underlying health conditions, risk factors for COVID-19 infection, and demographics.
