Expert sounds alarm of ongoing flu activity as cases spike in schools and care homes

The peak of flu season in the city is likely to continue, with an increase in influenza cases reported in schools and residential care homes, according to Centre for Health Protection controller Edwin Tsui Lok-kin.

Speaking in a TV program, Tsui noted that despite the recent figures indicating a decrease in influenza cases in general during the eighth week of flu season, the outbreaks in schools and residential care homes have increased.

Tsui pointed out that the flu activity remained high, especially since the resumption of classes after the Lunar New Year, with a total of 23 related outbreaks recorded last week.

Among the 117 affected individuals, Tsui revealed that over 50 percent of the cases were found in schools.

Tsui added that influenza activity is still elevated, compared to the average of approximately 12 outbreak cases per week from the previous two weeks. 

In addition, Tsui called for public attention to Norovirus, another common virus in Winter, stating a rise in gastroenteritis cases since December. 

He reported 76 outbreaks affecting over 800 individuals, urging the public to maintain good personal, environmental and food hygiene.

As the Norovirus is highly infectious, Tsui warned even a small amount of Norovirus could lead to infection, noting the virus can be transmitted through various channels, including eating contaminated food and contacting infected persons’ vomitus or feces.

Furthermore, a secondary outbreak is likely to occur when vomit occurs in confined spaces with poor ventilation, Tsui added.

As spring is approaching, Tsui advised citizens to be cautious of gastrointestinal inspections, food poisoning, and dengue fever, which most likely occurred during the upcoming rainy period.
