A French-Iranian academic detained in Tehran has returned to her prison cell after a stay in hospital, her lawyer said on Sunday. Said Dehghan said his client Fariba Adelkhah had been taken back to the women’s wing of Evin prison, where jailed mother Nazanin Zaghari-Ratcliffe is being held. Ms Zaghari-Ratcliffe <a href="https://www.thenational.ae/world/mena/nazanin-zaghari-ratcliffe-british-iranian-prisoner-suspected-to-have-coronavirus-1.986292">is suspected to have coronavirus,</a> her family said on Saturday in a statement urging officials at the prison to test her for Covid-19. The British-Iranian dual national said in the statement: "I am not good. I feel very bad in fact. It is a strange cold. Not like usual. I know the kinds of cold I normally have, how my body reacts." Mr Dehghan said authorities had agreed to his call to ban conjugal visits to the prison to prevent the spread of the virus. Ms Adelkhah, who has been held in Tehran since June last year, is due to go on trial on Tuesday on charges including conspiring against national security. The researcher from the Sciences Po University in Paris denies the accusations against her. She was admitted to hospital after her health deteriorated as a result of a six-week hunger strike, which she ended in February. Her lawyer said she returned to her cell despite still complaining of kidney pain. Relatives of <a href="https://www.thenational.ae/world/europe/iran-prisoners-fear-coronavirus-spread-1.984950">inmates at Evin Prison have spoken of their concern</a> at the threat of coronavirus in a country where the infection rate is rapidly growing. Iran is one of the worst affected countries from the outbreak with 978 officially declared cases and 54 deaths. Tehran-based MP Mahmoud Sadeghi, who revealed last week he had been infected by the virus, has urged political prisoners to be released from Evin prison so they can escape the epidemic.
