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.
