The SARS- epidemic occurred in the Guangdong Province of Southern China in November 2002 and had spread over >30 countries resulting in 774 deaths [25]. The disease transmission was most likely associated with a zoonotic occurrence in the wild animal markets in China. Bats are considered to be the reservoir hosts for coronavirus. It was reported that civet cats were the intermediate hosts that contacted bats before being sold in the animal market [25]. Soon after the isolation of SARS-CoV, SARS-CoV-like viruses were found in Himalayan palm civets and raccoon dogs, with 99.8% nucleotide homology for human SARS-CoV [26]. SARS-CoV transmission is mainly through direct contact person-to-person, through respiratory droplets, with an incubation time of 2 to 11 days after exposure [20].
