The results of the study were published in the British Journal of Dermatology. Researchers tested biopsy samples from patients with atypical skin diseases who had not been diagnosed in the last few months of 2019 and found that the patient was infected with the new coronavirus, and her symptoms were red patches on the skin and slight sore throat. In addition, the patient was tested positive for new coronavirus antibodies in a serum test in June 2020. Researchers at the University of Milan believe that this is currently the earliest case of new coronavirus infection found in Italy.
The leader of the research team, Gianotti from the University of Milan, told the media that in the next study, samples of new coronavirus infections earlier than November 2019 may be found. He said that the study found that some patients infected with the new crown virus only showed symptoms of skin diseases, so they wanted to know if any of the skin disease patients before the outbreak of the new crown virus had been infected with the new crown virus.
Previously, researchers have detected the new coronavirus in urban wastewater samples from the northern cities of Milan and Turin in December 2019. In November 2020, researchers from the National Cancer Institute in Milan, Italy and other institutions published a paper in the country’s “Journal of Oncology” saying that the new crown virus may have spread in Italy as early as September 2019, which is more than the first case of new crown confirmed in Italy. The case was a few months earlier.
