The husband of a British-Iranian woman jailed in Iran believes his wife has contracted coronavirus as he expressed concern at the prison's "refusal to test her".

Richard Ratcliffe called on the Government to insist that Nazanin Zaghari-Ratcliffe was immediately tested for the virus by officials at the Evin prison in Tehran.

Although there are currently no confirmed cases at the prison, Covid-19 has spread rapidly across Iran - with at least 43 dead amid 593 patients identified.

In an update on Saturday, issued through the Free Nazanin Campaign, Ratcliffe said his wife had seen "no improvement" and was suffering with a continual cold sweat and a feeling of nausea.
In a phone call with her family, Zaghari-Ratcliffe said: "For a long time this has not felt like a normal cold.

"These symptoms have lasted almost a week. I know I need to get medicine to get better. This does not go magically."

Ratcliffe said his wife had informed the prison guards of her symptoms and that she suspected she could be suffering from coronavirus, but she is yet to be tested.

Following reports of conditions at the prison on Friday, he said a new batch of disinfectants, gloves and masks were made available to the ward.

"We are concerned by the prison authorities' refusal to test her and the wider suppression of coronavirus inside the Iranian prison system," Ratcliffe said.

"We call on the UK Government to insist that Nazanin is tested for coronavirus immediately and is treated properly.

"We further call on the Prime Minister to take charge as part of his coronavirus efforts to ensure that British Iranians held hostage in Evin prison are diplomatically protected."

On Thursday, Commons leader Jacob Rees-Mogg said that while the Iranian authorities have denied any outbreak of coronavirus at the prison, he would "not always take as authoritative" such remarks.

Zaghari-Ratcliffe was arrested at Tehran's Imam Khomeini airport while travelling to show her young daughter, Gabriella, to her parents in April 2016.

She was sentenced to five years in prison over allegations, which she denies, of plotting to overthrow the Tehran government.

She was later afforded diplomatic protection by the UK Government, which argues that she is innocent and that her treatment by Iran failed to meet obligations under international law.
