On February 2020, the Diamond Princess Cruise, which left Japan, was obliged to stay at sea for 14 days-quarantine after it was found that a Hong Kong passenger had been diagnosed SARS-COV2 pneumonia after disembarking. As a result shocked the world, an outbreak of infection occurred on board; the number of infected people increased rapidly; and about 20% of the population infected. Finally, the quarantine is completely failed and has to be ended officially. The crowd was evacuated back to their own country. The incident can be seen as an experimental model of virus infection in an independently enclosed building, showing powerful air-borne transmission of the virus to pass through public ventilation ducts and crevices in doors and windows. There have trend that no is immune; there have no racial differences and all world people are generally susceptible. The populations of asymptomatic recessive infection are large and are a dangerous infection source. The failure of closed quarantine indicates that evacuation is the best quarantine and protection. To sum up, mistake quarantine = forced infection; ineffective quarantine = condoning spreading; excessive quarantine = wasting resources. The only right way is to evacuate the infected immediately and disperse the uninfected quickly.
