Abstract: The first confirmed death from coronavirus infection occurred on 9 January 2020. On January 23, 2020, the Wuhan center was placed in quarantine, where all public transport in Wuhan and Wuhan were suspended. The nearby cities of Huanggang, Ezhou, Chibi, Jingzhou and Zhejiang have also been quarantined since 24 January 2020. Coronavirus 2019-nCoV was identified in Wuhan, Hubei Province, China, after people developed pneumonia without a clear cause and for which existing vaccines or treatments were not effective. The virus shows evidence of person-to- person transmission, and the transmission rate (infection rate) appears to have escalated in mid-January, from other cases than those reported by China so far. The first cases of coronavirus in Romania and the Republic of Moldova were confirmed on February 26 and March 7, 2020 respectively. Keywords: coronavirus pandemic, quarantine, number of deaths, number of diseases JEL classification: C 30

1. Introducere The 2019–20 coronavirus pandemic, also known as the Wuhan coronavirus, outbreak of Chinese pneumonia or Wuhan pneumonia began on December 12, 2019 in downtown Wuhan, China, when a group of people with pneumonia of unknown cause appeared, was mainly related to the stall owners who worked at the Huanan fish market, who also sold live animals. Subsequently, Chinese scientists isolated a new coronavirus, called 2019-nCoV, which was found to be at least 70% similar in the sequence of SARS-CoV genes. [1] [2] Coronavirus 2019-nCoV was identified in Wuhan, Hubei Province, China, after people developed pneumonia without a clear cause and for which existing vaccines or treatments were not effective. The virus shows evidence of person-to- person transmission, and the transmission rate (infection rate) [3] appears to have escalated in mid- January, from other cases than those reported by China so far. [ 4] The first cases of coronavirus in Romania and the Republic of Moldova were confirmed on February 26 [5] and March 7, 2020 [6] respectively. On March 11, 2020, the World Health Organization declared the coronavirus outbreak a pandemic. [7] The first suspected cases were reported on 31 December 2019, [17] the first cases of symptomatic disease occurring just over three weeks earlier on 8 December 2019. [18] The market was closed on 1 January 2020 and people who showed signs and symptoms of coronavirus infection were isolated. More than 9,930 people, who came into close contact with potentially infected people, were initially monitored. Following the development of a specific diagnostic chain polymerization reaction test for infection detection, the presence of 2019-nCoV was subsequently confirmed in 41 people in the Wuhan cluster, [19] two of whom were subsequently reported as married couples, one of whom had not been present on the market and three other members of the same family working at the market's seafood stands. [20] [21] The first confirmed death from coronavirus infection occurred on 9 January 2020. [22] On January 23, 2020, the Wuhan center was placed in quarantine, where all public transport in Wuhan and Wuhan were suspended. The nearby cities of Huanggang, Ezhou, Chibi, Jingzhou and Zhejiang have also been quarantined since 24 January 2020. [23] [24]
