• Researchers into initial cases find first person with symptoms had no contact with market where disease is believed to have originated
  • Call for preparedness against airborne transmission, including fitted respirators and other personal protective equipment
The first person known to have been infected by the Wuhan coronavirus  had never visited the city’s seafood market – regarded as the epicentre of the outbreak
– according to Chinese researchers, who also called for extra precautions against airborne transmission of the disease between humans.

The researchers, seven of whom work at Wuhan’s Jinyintan hospital, designated for patients with the illness, revealed on Friday in The Lancet medical journal that symptoms of the new disease were first reported on December 1 – much earlier than the Wuhan government’s initial announcement on December 31 of 27 cases of the pneumonia-like infection.
