Is 2019-nCoV the same as the MERS-CoV or SARS virus?
No. Coronaviruses are a large family of viruses, some causing illness in people and others that circulate among animals, including camels, cats and bats. The recently emerged 2019-nCoV is not the same as the coronavirus that causes Middle East Respiratory Syndrome (MERS) or the coronavirus that causes Severe Acute Respiratory Syndrome (SARS). However, genetic analyses suggest this virus emerged from a virus related to SARS. There are ongoing investigations to learn more. This is a rapidly evolving situation and information will be updated as it becomes available.
