Kim Jong Un's henchmen were seen weeping as they were told the North Korean leader had been "seriously ill".
His fanatical cronies, who were clad in military uniforms, broke down in tears as the tyrant's sister shared news that he had suffered a "fever".
Kim Yo-Jang claimed her despot brother didn't "lie down even for a second while thinking of only of his responsibility for the people."
She said: "The victory gained by our people is a historic event that once again showed the world the greatness of our state, the indomitable tenacity of our people and the beautiful national customs we are proud of."
Footage showed members of the audience with tears streaming down their faces after the younger sibling's fiery speech.
She went on to threaten South Korea with "extermination" for having spread the virus into their isolated nation.
Speaking after his sister, Kim went on to declare North Korea had achieved a "shining victory" over Covid-19.
He also called for lockdown and containment measures to be eased as he claimed the country had only lost 74 North Koreans to coronavirus.
He hailed it as an "unprecedented miracle in the history of the world health community", state media reported.
The multitude of lies were revealed in a party workers' event in Pyongyang for a "national meeting for reviewing the emergency anti-epidemic work".
The outbreak was first announced in the country on May 12 this year.
Kim Yo-jong also blamed the outbreak of Covid-19 in the country on contaminated leaflets sent over the border by South Korea.
She claimed South Korea was behind the leaflets and the North would issue an armed response if they did not stop.
South Korea roundly rejected the claim.
Activists in South Korea are known to send balloons over the border with leaflets that contain criticisms of Kim Jong-un, but it is unlikely that they caused an outbreak of Covid.
There were large gatherings in April this year and the country also opened its borders to freight traffic from China in January.
The state's official death toll from Covid stands at 74, described by Kim as an "unprecedented miracle in the history of the world health community."
This is unlikely and there have been reports of around 4.8 million cases of fever, but not described as Covid.
The country is known to have a lack of testing kits available and claimed to have not recorded a single case of the virus in the first two years of the pandemic.
World Health Organisation (WHO) emergencies chief Michael Ryan said in June: "We assume the situation is getting worse, not better.
"We have real issues in getting access to the raw data and to the actual situation on the ground."
The dictator added: "The victory gained by our people is a historic event that once again showed the world the greatness of our state, the indomitable tenacity of our people and the beautiful national customs we are proud of."
Experts do not believe the country's healthcare system is good enough to stand up to the threat of Covid due to poor equipment, a lack of vaccines and minimal intensive care units.
