The US Ambassador to Guyana Sarah Ann Lynch and the British High Commissioner Greg Quin have both tested negative for COVID-19.
The two underwent the test on Thursday after news broke that the Foreign Minister, Hugh Todd had tested positive.
Both diplomats had one on one meetings with the Foreign Minister the day before his positive test was revealed.
The two diplomats also held meetings with the President and other key government officials in the past week and also attended the inauguration ceremony at the National Cultural Centre. More than 800 persons attended that indoor event.
With their negative test results, the two Heads of Mission and their Deputies are still expected to remain self-quarantined for the coming days.
