Following treatment for a "possible" infection, Thailand's palace confirmed on Monday (Aug. 1) that King Bhumibol Adulyadej has been hospitalised in the country's capital. Among the monthly updates given on the 88-year-old royal's health, a report also stated that he'd recently been monitored for a build-up of cerebrospinal fluid.
The world's longest reigning monarch is currently residing at the Siriraji hospital in Bangkok and crowds of well-wishers have gathered outside in support of their king.
A statement from the palace read: "In the month of July 2016 a low fever was present. Blood tests showed a possible infection and physicians therefore had to administer antibiotics. After the treatment His Majesty's condition showed some improvement."
He has been admitted to hospital several times over the past couple of years, and was last seen in public on 11 January when he spent time visiting his Bangkok palace.
Last month the king was treated for hydrocephalus, or water on the brain, and a lung and knee infection. Following the successful operations, the palace said: "The medical team has continuously monitored the condition of the cerebrospinal fluid throughout the month of July to be satisfactory."
Most Thai people have never known life under another king or queen, and the country has strict laws protecting its royals from insults or threats. Royal defamation is a crime punishable by up to 15 years in prison.
