The main difference between human coronavirus and Covid 19 is that Covid 19 is a novel coronavirus, meaning it is a new strain of coronavirus that has not been previously identified in humans. Human coronaviruses are a group of viruses that cause illnesses ranging from the common cold to more severe diseases such as Middle East Respiratory Syndrome (MERS) and Severe Acute Respiratory Syndrome (SARS). Covid 19 is a new strain of coronavirus that is believed to have originated in animals and has since spread to humans. It is much more contagious than other human coronaviruses and has caused a global pandemic.
