LONDON: The novel coronavirus has existed worldwide and broke out whenever and wherever favourable conditions occurred before it emerged in China last December leading to the ongoing global pandemic, an Oxford University expert said.
"I think the virus was already here -- here meaning everywhere. We may be seeing a dormant virus that has been activated by environmental conditions," Xinhua news agency quoted Tom Jefferson, a senior associate tutor at the Centre for Evidence-Based Medicine (CEBM) at Oxford and a visiting professor at Newcastle University, as saying.
"There was a case in the Falkland Islands in early February. Now where did that come from? There was a cruise ship that went from South Georgia to Buenos Aires, and the passengers were screened and then on day eight, when they started sailing towards the Weddell Sea, they got the first case. Was it in prepared food that was defrosted and activated?"
"Strange things like this happened with Spanish Flu. In 1918, around 30 per cent of the population of Western Samoa died of Spanish Flu, and they hadn't had any communication with the outside world," Jefferson added.
"The explanation for this could only be that these agents don't come or go anywhere. They are always here and something ignites them, maybe human density or environmental conditions, and this is what we should be looking for," he stressed.
Last week, Spanish virologists announced the discovery of traces of the novel coronavirus in a sample of Barcelona waste water collected in March 2019, nine months before COVID-19 was identified in China.
The Italian National Institute of Health said last month that sewage water from Milan and Turin showed coronavirus traces on December 18, 2019.
By Tuesday morning, the total number of global COVID-19 cases stood at 11,590,195, while the fatalities rose to 537,429, according to the Johns Hopkins University.
