A paramedic who complained about being forced to work despite contracting coronavirus is in critical condition after he fell from a hospital window in western Russia this weekend, local media reported.

This is at least the third incident in which a Russian healthcare professional has plunged from a hospital building under mysterious circumstances in the past two weeks. The two previous doctors have died from their injuries.

Alexander Shulepov is in critical condition with a skull fracture after falling from the second floor of a rural hospital where he was being treated for Covid-19, the local crisis center told the Vesti Voronezh outlet Saturday.

Shulepov, 37, and his colleague filmed a video on April 22 complaining that the chief doctor of the Novaya Usman village hospital forced him to work despite the fact that he tested positive for Covid-19.

A second video appeared three days later in which Shulepov denied his initial “emotional” claims. His colleague Alexander Kosyakin reportedly faces criminal charges for spreading “fake news” about the virus, which carries a prison sentence of up to five years under a recently passed federal law.

Police have reportedly launched an inspection into Shulepov’s fall from the hospital in the Voronezh region 500 kilometers south of Moscow.

The Voronezh region has confirmed 636 coronavirus cases as of Monday, less than 1% of Russia’s 145,268 confirmed cases. At least 41 doctors and patients at the region’s largest hospital have reportedly been infected with Covid-19.
