Anosmia, a Hidden Sign for COVID-19? A Case Report and Literature Review

Karen ChristelleNani Draman


Background The coronavirus disease 2019 (COVID-19) is an ongoing viral pandemic that is actively affecting 210 countries worldwide, with a total of more than 1.5 million cases and 106 000 deaths. Symptoms associated with COVID-19 are mainly fever, cough, dyspnea and sore throat. The current indication for COVID-19 testing includes presence of these symptoms with a positive history of travel to affected countries or contact with COVID-19 patients. Anosmia has been recently reported anecdotally over the past weeks as an emerging symptom of the COVID-19 but has yet to gain recognition as a symptom for COVID-19 by the World Health Organization (WHO) and Centre for Disease Control and Prevention (CDC). This case report highlights a case of isolated sudden onset of anosmia as a presenting symptom of COVID-19 and relevant literature review supporting the incidence of anosmia in COVID-19. This is a first case report of anosmia in COVID-19 occurring in pregnancy.Case Presentation A 30-year-old pregnant lady at 11 weeks of gestation presented with sudden onset of anosmia for one day with no other accompanying symptoms. She had just recovered from a mild cold a day prior to the development of anosmia. She had a history of travel by land t...Continue Reading

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Hereditary Sensory Autonomic Neuropathy

Hereditary Sensory Autonomic Neuropathies are a group of inherited neurodegenerative disorders characterized clinically by loss of sensation and autonomic dysfunction. Here is the latest research on these neuropathies.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Landau-Kleffner Syndrome

Landau Kleffner syndrome (LKS), also called infantile acquired aphasia, acquired epileptic aphasia, or aphasia with convulsive disorder, is a rare childhood neurological syndrome characterized by the sudden or gradual development of aphasia (the inability to understand or express language) and an abnormal electroencephalogram. Discover the latest research on LKS here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.


Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.

Regulation of Vocal-Motor Plasticity

Dopaminergic projections to the basal ganglia and nucleus accumbens shape the learning and plasticity of motivated behaviors across species including the regulation of vocal-motor plasticity and performance in songbirds. Discover the latest research on the regulation of vocal-motor plasticity here.
