A three-year-old Chinese boy quarantined in Bangkok after getting off a flight from Wuhan in China with a mystery illness has been given the all-clear and discharged from hospital.
"He had a fever as a result of A H3N2 influenza which is not dangerous," Apichart Vachiraphan, director of Bamrasnaradura Infectious Diseases Institute said on Tuesday.
However, doctors would keep checking his condition, he told a media briefing.
The boy was one of four air passengers quarantined for health checks since Monday following an outbreak of an unidentified respiratory disease in Wuhan.
The other three are Thai nationals, two of whom are female students who have also been quarantined at the institute. The other patient is at a private hospital.
Dr Apichart said a first round of tests on both students came out negative for viral pneumonia. However, one 24-year-old student had the type C flu virus, while the other, aged 22, was suffering from a Respiratory Syncytial Virus (RSV) infection, he said.
The results of the final tests on them will will be revealed on Wednesday, added.
If these prove negative, they will be allowed to go home, he said. The fourth patient in the private hospital has also not tested positive for anything dangerous.
"There's no further reports from the Department of Disease Control and hospitals about other people showing strange symptoms," Dr Apichart said.
Since last month, at least 59 people in Wuhan have been diagnosed with a mysterious infection which is believed to have originated in a seafood market in the city, according to Wuhan health officials.
The virus has not been identified, but officials said it is not bird flu, Middle East respiratory syndrome (Mers), severe acute respiratory syndrome (Sars), or adenoviruses.
