Consultant tells of battle to prevent deadly outbreak of Sars-like virus
London consultant returns to his home city to share experiences dealing with Sars-like virus

The tests on the 49-year-old man lying ill in St Thomas' Hospital in London last year were confusing.
"The patient tested positive for coronavirus, but he also tested negative for each and every known coronavirus," virologist Tong Cheuk-yan said. "It was then that I started to suspect it might be a new virus."
The Hong Kong-graduated doctor was speaking about the tense situation in which he diagnosed the first patient in England with the deadly new Sars-like virus.
"We could not find a match on his virus," said Tong, a consultant for the Barts Health NHS Trust.
"But we noticed on the very same day that there was a report about a novel coronavirus in Saudi Arabia. We started to suspect it due to the patient's travel history. It was lucky that we … related it to the new virus in the Middle East within 24 hours."
The patient had fallen ill on a visit to his homeland, Qatar, and was airlifted to London. He was treated in a private hospital before being admitted to St Thomas' on September 20.
