The policy change was made at the request of doctors at hospitals specially designated to treat the new coronavirus, which often causes pneumonia. Tests for COVID-19, the respiratory disease caused by the new coronavirus, were producing accurate results only 70%-80% of the time, the doctors said.
Reuters reported last month that a sharp spike in the incidence of pneumonia in Moscow had fuelled concerns about the reliability of official data on the number of cases, which at the time was well below levels seen in other European capitals. "In some cases, the tests give false negative results, and the proportion of such results is significant," Protsenko was cited as saying.
