Great Britain's Gabriella Taylor is continuing to receive hospital treatment for an unknown virus which forced her to withdraw from Wimbledon.
Taylor had to retire from her girls' singles quarter-final on Thursday against Kayla Day of the USA.
The 18-year-old from Southampton posted on Twitter on Monday that she has been under observation at the city's General Hospital for four days.
Her agent told BBC Sport Taylor is in a stable condition and improving.
The world number 377 is being kept on an isolation ward in hospital and is waiting for blood tests to reveal more details.
