The Centre for Health Protection (CHP) of the Department of Health is today (June 4) investigating an influenza B outbreak at a primary school in Sham Shui Po, and reminded members of the public who have not yet received seasonal influenza vaccination in the 2018-19 season that they can still receive it for personal protection against seasonal influenza.

     The outbreak involves 28 boys aged 7 to 11 who developed fever, cough and sore throat since May 17. Among them, 27 sought medical attention and two required hospitalisation and have been discharged upon treatment. All are in a stable condition. The respiratory specimens of four children tested positive for influenza B upon laboratory testing.

     Officers of the CHP have conducted a site visit and advised the school to adopt infection control measures against respiratory tract infections. The school has been placed under medical surveillance.

     A spokesman for the CHP said, "To prevent outbreaks of influenza and other respiratory infections, it is of prime importance that students with fever, regardless of the presence of respiratory symptoms, should not be allowed to attend school. They should seek medical advice and avoid school till 48 hours after the fever has subsided. Schools should also measure and record students' body temperature properly."

     Schools are reminded to follow the Guidelines on Prevention of Communicable Diseases on preventive and control measures as well as management of outbreaks, which should be reported to the CHP for prompt follow-up.

     "The latest surveillance data showed that there has been a recent surge in local seasonal influenza activity. Members of the public aged 6 months or above (except those with known contraindications) who have not yet received seasonal influenza vaccination in the 2018-19 season can still receive it for personal protection against seasonal influenza," the spokesman said.

     "Meanwhile, the public should continue to adopt strict personal, hand and environmental hygiene practices against respiratory illnesses and other infectious diseases," the spokesman added.

     The public may visit the CHP's influenza page and weekly Flu Express for more information.
