“…Anosmia has already been reported in the course of SARS and other coronavirus infections; however, it represents a rare occurrence. Interestingly, in COVID‐19 patients ageusia and anosmia are not accompanied by nasal obstruction or other rhinitis symptoms.…”

“…Anosmia has already been described in common coronavirus infections. 15,16 In 2006, Hwang 17 described a case of anosmia that persisted for 2 years after SARS had been contracted. In 2001, Schwob et al 18 and Youngentob et al 19 evaluated the anatomopathological and functional consequences of olfactory bulb line variant mouse hepatitis virus intranasal inoculation in murine models.…”

From the first reports, ageusia and anosmia appear to be frequent clinical features in coronavirus disease 19 (COVID-19) patients. We have performed a survey of the literature, analyzing the possible causes of these chemosensory alterations, which may be useful as a starting point for specific further studies. Dear Editor,The rapid spread of the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) in Europe and America is enabling researchers to acquire a large amount of clinical data.

“…Post viral olfactory dysfunction (PVOD) is a common feature with the observed incidence of 18-45% [30]. Moreover, anosmia has been reported specifically in the course of severe acute respiratory syndrome (SARS) [31] and other coronaviruses [32] infections but it still holds a rare occurrence. Early indications are that the SARS-CoV-2 virus requires ACE-2 and TMPRSS2 to enter cells [33].…”

While the world is fighting against the newly emerged highly contagious coronavirus strain, new evolving ideas regarding symptoms and investigations are reverberating among health care professionals to combat the public health emergency. The study aims to review various presenting symptoms of COVID-19 especially the unusual one and analyzing the importance of olfactory and taste disturbances. 20 studies published recently in the last 1 year were analyzed and discussed for insights into the unusual presentation of symptoms in COVID-19 patients. All the findings and statements in this review regarding the pandemic are based on published information as listed in the references. Most research articles initially focused on fever and respiratory symptoms. Later gastrointestinal symptoms were also taken into consideration. Only 5 studies from the literature have mentioned any smell and taste disturbances after SARS-CoV-2 infection to date. So changing trends can be seen in publications and recognizing these symptoms has important to timely combat this disease. The majority of corona virus-infected patients suffer from mild to moderate severity of the disease. Much hyped up symptoms of the respiratory tract may not be shown by a greater number of patients. So the need of the hour especially in developing and densely populated nations is to recognize unusual symptoms of COVID-19 especially its influence over smell and taste sensation to prevent any delay or misdiagnosis.
