ABSTRACT

Human respiratory illnesses can be caused by the coronavirus family of viruses. The virus's surface features spikes that resemble crowns are what give them their name, "corona." The virion of coronaviruses has a spherical form with a diameter ranging from 80 to 120 nm. It is surrounded by trimers of the Spike protein (S), which are referred to as spikes. Hemagglutinin esterase (HE) is also involved in the creation of the so-called "crown" in the HCoV-OC43 and HCoV-HKU1 coronaviruses. According to Kline, low-grade fever appears to be one of the most prevalent early indicators of COVID-19, although not everyone will experience a temperature. Headaches, aches in the muscles, appetite loss, and loss of taste or smell are among other possible symptoms. Symptoms may develop two to fourteen days following exposure.
