"The Lombardy outbreak came to light when a 38-year-old Italian tested positive in Codogno, a comune in the province of Lodi. According to his wife, he had met an Italian friend who had returned from China on 21 January, who subsequently tested negative.[20] On 14 February, he felt unwell and went to a doctor in Castiglione d'Adda. He was prescribed treatments for influenza.[20] On 16 February, as the 38-year-old man's condition worsened, he went to Codogno Hospital, reporting respiratory problems.[20] Initially, there was no suspicion of COVID-19, so no additional precautionary measures were taken, and the virus was able to infect other patients and health workers.[21] Later, the patient, his pregnant wife, and a friend tested positive.[20] Three more cases were confirmed on the same day, after the patients reported symptoms of pneumonia.[22] Thereafter, extensive screenings and checks were performed on everyone that had possibly been in contact or near the infected subjects.[23] The 38-year-old man was asymptomatic for weeks, reportedly led an active social life, and potentially interacted with dozens of people before spreading the virus at Codogno Hospital.[20][21] Afterwards, he was transferred to Policlinico San Matteo in Pavia,[24] and his wife to Sacco Hospital in Milan.[25][26] " [1] [1] https://en.wikipedia.org/wiki/2020_coronavirus_outbreak_in_Italy#Lombardy_cluster https://en.wikipedia.org/wiki/2020_coronavirus_outbreak_in_I...
