Among others, the group included Marion Koopmans, Thea Fisher, Hung Nguyen and Chinese veterinary expert Yang Jungi, who participated in a joint investigation in Wuhan, China.
"We are very pleased with the group of selected experts and look forward to working with them to make the world a safer place," WHO Director-General Tedros Ghebreyesus said .
The team will examine whether the virus was transmitted from animals to humans in the markets of Wuhan or leaked as a result of an accident in the laboratory.
The WHO said the group could be "our last chance" to determine the origin of SARS-CoV-2.
According to Ghebreyesus, it is the study of the causes of new pathogens that is "necessary to prevent future outbreaks."
The previous group published its investigation, but it was criticized for its lack of transparency and access, and for failing to analyze the theory of laboratory leaks in more depth.
As it was reported earlier, the WHO recommended that the elderly people and individuals with weak immune system get the third shot of the vaccine from coronavirus.
