The CDC confirms that there are four main sub-groups of coronaviruses, known as alpha, beta, gamma, and delta that cause the common cold.The Centers for Disease Control and Prevention in its technical brief has said that there are common human coronaviruses, known as alpha(229E), beta(NL63), gamma(OC43), and delta(HKU1). Usually, these types of virus would cause mild to moderate upper-respiratory tract illnesses, like the common cold. It is mentioned that runny nose, sore throat, headache, fever, cough and a general feeling of being unwell are the symptoms of common human coronaviruses.

Similarly, a brief history of the coronavirus states that the first human coronaviruses were identified in the 1960s. There are seven coronaviruses which could cause disease in humans. Four viruses are endemic and usually cause mild to moderate diseases in humans. Further, these types of viruses are found all over the world and are responsible for about 10-15% of common colds.
