The Office of the Director of National Intelligence has said that virus 'was not man-made or genetically modified.'
However, it said it was still investigating how the nature-born virus entered the population, and whether it was transferred to humans from animals or accidentally from a sample held by scientists in a lab, the BBC reported.
The statement said, 'The [intelligence community] will continue to rigorously examine emerging information and intelligence to determine whether the outbreak began through contact with infected animals or if it was the result of an accident at a laboratory in Wuhan.'
Covid-19 was first detected in humans in Wuhan, a province of China.
It has since spread across the globe, infecting at least 3.2 million people and possibly many more.
Chinese authorities have rejected the possibility that a lab was source of the outbreak.
