GENEVA (Reuters) – The World Health Organization is sending a team to China next week to investigate the origins of the novel coronavirus, its head Tedros Adhanom Ghebreyesus told a briefing on Monday.

The United States, the WHO’s largest critic which has said it is leaving the U.N. agency, has called for an investigation into the origin of the coronavirus.

President Donald Trump and Secretary of State Mike Pompeo have said it may have originated in a laboratory, although they have presented no evidence for this and China strongly denies it.
