Some common viruses found in humans are coronaviruses, enteroviruses and RSV, notes the Maine Center for Disease Control & Prevention. Other common viruses are rhinoviruses, human parainfluenza viruses and rotaviruses. Viruses are found all around the world and cannot be killed by antibiotics. They most often cause respiratory and digestive diseases.
Coronaviruses comprise a large family of viruses that are spread through the air. They typically cause respiratory diseases such as Middle East Respiratory Syndrome Coronavirus, or MERS-coV. Severe acute respiratory syndrome, or SARS, is another disease caused by a coronavirus. As of 2015, the last known SARS case occurred in 2004, states the Maine Center for Disease Control & Prevention.
Some forms of the common cold are also caused by coronaviruses. However, the most common virus family that causes the common cold is the rhinovirus. A rhinovirus can spread between people through the air or by direct contact. In the United States, adults experience an average of two to three colds per year, notes the National Institute of Allergy and Infectious Diseases.
One common virus family that causes digestive illnesses is the rotavirus, notes the University of Rochester Medical Center. Rotaviruses can spread through infected food and water. They cause severe diarrhea, especially in children. In the United States, rotavirus infections are highest in the winter. Worldwide, approximately 500,000 children die each year from rotaviruses, notes the University of Rochester Medical Center.
