During the Corona period, an unidentified woman infected 71 people with the epidemic. However, the woman herself was very cautious, yet she infected other people. China's Center for Disease Control (CDC) has shared a study on this matter. Chinese CDC believes that the woman did everything right. After returning from the trip, she quarantined herself in her flat and she doesn't show any symptoms. The woman was also alone in the lift when she went to the flat. According to the study, the woman returned to her residence on March 19 in Heilongjiang, China, from a trip to America. In the test, she came out corona negative, despite this, she quarantined herself in the residence. But shortly after that, her neighbour used the same lift. Apart from this, the neighbour's mother and boyfriend came to attend a party. After this, on April 2, a person involved in that party suffered a stroke. The people involved in the party did not have any contact with any infected person. In addition, the researchers found in their research that the neighbour was infected due to using the lift. Later one of the team members went to the hospital for treatment of strokes. So he infected 28 people. Later, he was taken to another hospital where he infected 20 others.
