BANGKOK Ė The queen mother of Thailand has been admitted to the Chulalongkorn hospital in Bangkok with the flu, the Royal Household Bureau said in a statement on Monday.
Sirikit, who turned 86 on Aug. 12, had fever and cough on Sunday, and her doctors recommended that she be hospitalized, according to the official statement.
After conducting several tests, the hospitalís doctors confirmed that the queen mother had contracted the flu.
In 2012, Sirikit was diagnosed with ischemic cardiac pathology, a condition caused by arteriosclerosis of the coronary arteries, and remained in hospital for four years.
She has made no public appearances since then, although the Royal Household announced in November 2016 that she had returned to the Dusit Palace in Bangkok after being discharged.
Her husband, King Bhumibol Adulyadej, passed away on Oct. 13, 2016, aged 88 years, after reigning for seven decades.
Bhumibol and Sirikitís only son, Vajiralongkorn, was declared the King of Thailand on Dec. 1, 2016, but the coronation ceremony was postponed until the end of the mourning period, and is still to be held.
Vajiralongkorn, also known as Rama X, is the 10th monarch of the Chakri dynasty, founded by Rama I (born Phutthayotfa Chulalok) in 1782.
