Abstract There are no robust data on the real onset of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and spread in the prepandemic period worldwide.
We investigated the presence of SARS-CoV-2 receptor-binding domain (RBD)–specific antibodies in blood samples of 959 asymptomatic individuals enrolled in a prospective lung cancer screening trial between September 2019 and March 2020 to track the date of onset, frequency, and temporal and geographic variations across the Italian regions.
SARS-CoV-2 RBD-specific antibodies were detected in 111 of 959 (11.6%) individuals, starting from September 2019 (14%), with a cluster of positive cases (>30%) in the second week of February 2020 and the highest number (53.2%) in Lombardy.
This study shows an unexpected very early circulation of SARS-CoV-2 among asymptomatic individuals in Italy several months before the first patient was identified, and clarifies the onset and spread of the coronavirus disease 2019 (COVID-19) pandemic.

不知道可以google雖然我還是覺得這整噗聊的都很好笑就是了不過名詞是真的可以不用發問了忽然好平靜那怕中國消滅的這個病毒也是一樣的
因為想要噁心中國不需要任何理由嗎這邊先利申：不能投票，不支持現在的台灣政府和執政黨，
老實講台灣怎樣不關我的事就跟iPhone一樣那中國是什麼，因為美國有自己也要搞一個嗎
