Lindsay Lohan has been hospitalised in London with a rare virus.
The actress contracted Chikungunya, a virus transmitted by mosquito bites, in Bora Bora, where she vacationed over the holidays.
The virus causes fever, joint pain and fatigue.
She revealed the diagnosis on her Instagram.
Lohan appeared to have bounced back from the illness days later as she flew to Los Angeles, but it appears the virus is still playing havoc with her health.
She was treated at the King Edward VII, on Wednesday after complaining of a high fever and joint pain.
She was subsequently released by medics.
