The Russian military reported 2,090 cases of the coronavirus among its personnel, cadets and civilian employees, according to the country’s defense ministry.

From March through April 26, 874 servicemen have tested positive, the Defense Ministry said Sunday, adding that most of them were either isolated at home or in military hospitals.

Another 971 cases were found among cadets in military academies and schools across the country, and 245 civilians employed by the defense ministry have tested positive. The majority of patients showed no symptoms, the statement added.

Over the past weeks, reports had emerged in Russia’s independent media outlets about coronavirus outbreaks in military academies, including troops who took part in the Moscow rehearsals for the May 9 Victory Day parade.

Last week, the head of the prestigious Kirov Military Medical Academy in Moscow was fired for failing to implement adequate coronavirus measures.

“The academy made errors in implementing preventive measures at the faculty for the training of medics for foreign armies, which led to infection among some cadets,” the defense ministry said, according to state-run agency TASS. “Given that … the head of the academy, Alexander Fisun, was removed from his position.”

The defense ministry did not disclose the exact number of cases at the academy, saying that cases were found in foreign students as well as 55 cases in students of other faculties.

Several thousand servicemen have also been quarantined after they took part in dress rehearsals for the Victory Day parade in the Moscow region as late as April 6. At the time, Russia had officially reported over 6,000 coronavirus cases and Moscow officials had already banned gatherings of more than 50 people.

The massive parade marking the end of World War II in Europe, which usually has around 13,000 troops marching on the Red Square, has since been postponed by President Vladimir Putin.

The defense ministry is still moving ahead with its annual spring draft, with 135,000 army conscripts expected to be called up in May.
