CHP investigates two epidemiologically linked measles infection cases
The two cases are family members living together. The first case involves a six-month-old baby boy. He presented with fever on June 21, and developed cough, runny nose and skin rash the following day. He was brought to the Accident and Emergency Department of Kwong Wah Hospital on June 23 and was admitted for treatment. His respiratory specimen sample tested positive for the measles virus upon nucleic acid testing.
During contact tracing, the CHP found that the boy’s 29-year-old father also presented symptoms of measles, including fever and cough, on June 20 and developed skin rash on June 23. The CHP arranged the patient to attend the Accident and Emergency Department of Kwong Wah Hospital for isolation and testing on June 24. His respiratory specimen sample tested positive for the measles virus upon nucleic acid testing.
An epidemiological investigation revealed that the baby boy has not yet reach the age to receive the first dose of the measles vaccine, while his father was uncertain whether he had received measles vaccination. One of their household contacts also presented relevant symptoms earlier and has recovered now. Testing is being arranged for this household contact.
The CHP continues to investigate the cases to identify potential sources of infection and high-risk exposure. Initial investigation revealed that no epidemiological linkages have been established between these two cases and other confirmed cases previously recorded in Hong Kong.
The number of measles cases in some overseas countries remains at a high level this year. The outbreaks in North America (including the United States and Canada), Europe and neighbouring areas (including Vietnam, Cambodia and the Philippines) are ongoing due to the relatively low vaccination rate. Furthermore, an increasing number of measles cases have also been recorded in Japan and Australia this year. For those who plan to travel to measles-endemic areas, they should check their vaccination records and medical history as early as possible. If they have not been diagnosed with measles through laboratory tests and have never received two doses of measles vaccine or are not sure if they have received a measles vaccine, they should consult a doctor at least two weeks prior to their trip for vaccination.
