In one African country

I say right away: all events are invented, all similarities with real countries are random.

Although a new virus was already raging everywhere, in one African country no one was worried. Really, why bother people, blood from the blood of a blessed country? The Great Leader announced it himself, and everyone applauded.
Afterword there was decided to test someones, but only those who arrived in the blessed country through the capital's airport. "What else to test other ones, if they have no disease and can not be?" - declared the Great Leader. The people coughed and applauded his wisdom.
Some positive ones were found among arrivals. They were isolated and treated with the best foreign means. Every day there was announced how many people were sick in the capital of a blessed country, and how the country compares favorably with the whole world. The people coughed and applauded.
From those who recovered in these same observations, there was taken blood plasma and it was transfused to the Great Leader and his family in the name of the greatness of the blessed country. What is blood plasma, the people did not know, but applauded the Great Leader, who did not disdain anything in the name of the greatness of his country. People coughed, thinned out, but applauded.
When the epidemic ended and there was nowhere to go for foreign free tests, the entire population was tested. And it turned out that almost every ordinary person had some kind of antibodies to the virus! Here it is, as it happens in a blessed country, where each antibodies are innate. And everyone again applauded the wisdom of the Great Leader, who from the very beginning declared that no illness would take our man.
