The Hospital Authority today said a 19-month-old patient of Hong Kong Children’s Hospital has preliminarily tested positive for COVID-19 while antibodies were found in his blood specimen.


The 19-month-old boy was admitted to the hospital yesterday for an essential elective surgery.


A health declaration was made upon admission and he did not present with fever or respiratory symptoms.


A nasopharyngeal swab test was performed as a screening measure. The result released last night was preliminarily positive to the virus.


The boy and his accompanying mother were immediately put in an isolation room and then transferred to Queen Elizabeth Hospital for isolation.


Subsequent blood tests of the boy and his mother showed the presence of antibodies. They met the discharge criteria and have been discharged directly from the hospital.


The authority said with the presence of antibodies in their blood specimens, the pair should have acquired infection from the community earlier and have recovered.


Upon discussion with the Centre for Health Protection, it was agreed that there is no risk of transmission to others.


No patients in the same cubicle with the boy nor visitors and staff in the ward are classified as close contacts.


In addition, Princess Margaret Hospital reported two supporting staff members preliminarily tested positive for COVID-19.


One of them involves a patient care assistant who works in the Non-Emergency Ambulance Transfer Service section.


She has not come into contact with any suspected or confirmed COVID-19 cases. Her last working day was on August 21.


Three colleagues who had meals with her are classified as close contacts and need to be quarantined for 14 days.


Another case involves an operation assistant who works in the Accident & Emergency Department.


She had transported a confirmed COVID-19 case in the past 14 days but was not involved in any clinical care or high-risk medical procedures.


While no patients are classified as close contacts, two colleagues, who had meals with the operation assistant, are classified as close contacts and need to be quarantined.
