Yulia Skripal's health 'improving rapidly' after nerve agent attack

Yulia Skripal, 33, and her father were found slumped on a bench near a shopping center in Salisbury.

London (CNN)The health of the daughter of a former Russian double agent poisoned in a nerve agent attack in the UK is "improving rapidly," according to the hospital treating her.

Sergei Skripal and his daughter Yulia, 33, were poisoned on March 4 after being exposed to what the British government says was a military-grade nerve agent. They had been hospitalized in a critical condition since the attack.
"I'm pleased to be able to report an improvement in the condition of Yulia Skripal. She has responded well to treatment but continues to receive expert clinical care 24 hours a day," Dr. Christine Blanshard, Medical Director for Salisbury District Hospital, said in a statement.
    Sergei Skripal, 66, remains in a critical but stable condition but Yulia is "improving rapidly," the statement said.
      The Skripals were found slumped on a bench in an outdoor shopping complex in Salisbury, England. They had no visible injuries, according to police.
      The update on Yulia's condition comes a day after police said they believed the Skripals first came into contact with the nerve agent at Sergei Skripal's home in Salisbury.

      Front door pinpointed

        Police have identified the highest concentration of the nerve agent to date as being on the property's front door, London's Metropolitan Police said.
        "Traces of the nerve agent have been found at some of the other scenes detectives have been working at over the past few weeks, but at lower concentrations to that found at the home address," the police statement said.
        Police believe the Skripals first came into contact with the nerve agent at Sergei Skripal's home in Salisbury, pictured on March 6.
        Detectives plan to focus their investigation around Sergei Skripal's Salisbury home for the coming weeks and possibly months, the statement said. Yulia was visiting her father at the time they were poisoned.
