Where did the new coronavirus appear?
SARS-CoV-2 is a new strain of coronavirus that had not been seen in humans before. The epidemic began in the Chinese city of Wuhan, capital of the Hubei province. At first, the epidemic seemed to be linked to the South China Seafood City market. This market hosts merchants for seafood, poultry, bats, marmots and other wild animals, which indicates a probable animal origin of this virus. The virus was later confirmed to also transmit between humans. Cases have since been discovered in other regions of China and in other countries, often linked to a previous visit of Wuhan. The health authorities of the various affected countries are currently investigating this new coronavirus and the sources of the contamination.
