US Democratic presidential candidate Hillary Clinton has cancelled a campaign trip to California after being diagnosed with pneumonia, according to a BBC report.
Mrs Clinton was taken ill on Sunday at a 9/11 memorial ceremony, stumbling as she left the event early.
The candidate’s team said she was diagnosed with pneumonia on Friday and given antibiotics, but had become dehydrated at the New York event.
Her doctor said she was now re-hydrated and “recovering nicely”.
Mrs Clinton was due to leave for California on Monday morning for a two-day trip that included fundraisers and a speech on the economy.
Her personal physician, Dr Lisa Bardack, said: “Secretary Clinton has been experiencing a cough related to allergies. On Friday, during follow-up evaluation of her prolonged cough, she was diagnosed with pneumonia. She was put on antibiotics, and advised to rest and modify her schedule.”
On Sunday, video showed her being supported by aides as they put her into her van after she left the 9/11 ceremony in New York early.
She was taken to her daughter’s flat nearby and her team told reporters she was “overheated”. The candidate re-emerged later on Sunday, telling reporters: “I’m feeling great. It’s a beautiful day in New York.”
She then left for her home in Chappaqua, New York, and on Sunday evening Dr Bardack issued the health update.
Her Republican opponents have queried her physical fitness, with the presidential candidate Donald Trump telling supporters last month she “lacks the mental and physical stamina” to serve as president and fight Islamic State militants.
Mr Trump’s team has not yet made any comment on Mrs Clinton’s pneumonia diagnosis.
Last month Dr Bardack said she was “in excellent health and fit to serve as president of the United States”. She made a full recovery from surgery she underwent in 2012 for a blood clot, the doctor said.
The Clinton campaign has accused opponents of pushing a “deranged conspiracy about Clinton’s health”. Mrs Clinton is 68. Her Republican opponent Donald Trump is 70.
