Italian man was positive 28 times in a row after his death. Is the virus really so tenacious?

It is said that the source of infection in Italy may be a man in his forties with a history of diagnosis from Shanghai to Italy. The reason is that the man's family has been diagnosed, and he is also the first contact diagnosed in Italy. So this person probably brought the virus. Not long ago, rescuers salvaged a male body off the coast near the Italian city of Chieti. According to the epidemic prevention regulations, the man should be tested for nucleic acid. But I didn't expect the man's body to be positive for 28 consecutive tests. It is normal for the deceased to be tested positive for COVID-19 virus before his death, but the problem is that the deceased was not tested positive for COVID-19 virus before his death.

Before the corpse began to decompose, there was no further examination method, and the results did not change. However, the man's nucleic acid test has been negative and there are no uncomfortable symptoms, so it is likely to bring the source of infection of Italian virus. But there is a theory that this person heals himself. Strong resistance, may be asymptomatic, but it will infect patients 1 during the onset period, and it will be negative after conscious examination. This discovery also triggered a new study of COVID-19. The male corpse found in central Italy was positive for nucleic acid 28 times every 4 1 day, indicating that the epidemic situation in COVID-19 was terrible.

Similarly, those involved in the disposal of COVID-19's body were also warned not to contact the dead infected people in COVID-19. Through investigation, the identity of the deceased began to be exposed. The deceased was from Ukraine. Less than a day after his death, he and his friends went swimming in the sea. At that time, the weather was terrible. Shortly after entering the water, my friend couldn't find anyone else and had to ask the police for help. When he was found, he was sandwiched between rocks and showed no signs of life. Simply put, this virus is very cunning.

Even if it is negative, he may bring the virus to Italy. Finally his family was diagnosed. But this is unlikely. Because the probability and time of virus survival in vitro are relatively small, the probability of infection to others is also very low. So it is very unlikely that this person is the source of infection. However, the source of infection has been in an uncertain state and is now under study.
