Until late 1960s the coronaviruses were not recognized as pathogens responsible for human diseases (common cold), and it has been in 2003 when human coronaviruses (HCoVs) recalled worldwide attention with the emergence of the severe and acute respiratory syndrome (SARS), produced by a coronavirus (SARS-CoV) that has infected more than 8000 people, killing about ten percent of them in 32 countries. The increase of research on coronaviruses has soon lead to the discovery of another human coronavirus (HCoV-NL63) which is prevalent in 7% of hospital patients and has been associated with bronchiolitis and, possibly, conjunctivitis.

Human coronaviruses caused the SARS epidemic that infected more than 8000 people, killing about ten percent of them in 32 countries. This book provides essential information on these viruses and the development of vaccines to control coronavirus infections.
