China halts some classes amid school Covid-19 cluster, flu’s return

BEIJING – A number of schools across China halted classes earlier this week to stem the spread of Covid-19 and other pathogens ranging from flu to the norovirus, as the country begins to see a comeback of other illnesses after pandemic restrictions were eased.

Ten second-grade pupils in the same classroom tested positive for Covid-19 last weekend in the eastern e-commerce hub of Hangzhou, prompting local education authorities to suspend their class for four days from Monday. The pupils were most likely infected for the first time, officials said.

Shanghai suspended in-person teaching for an elementary school class after four pupils were diagnosed with the flu and others developed similar symptoms.

Flu cases – and subsequent class suspensions – were also reported in other schools across Zhejiang province, capital Beijing and nearby city Tianjin.

The fresh surges parallel what was seen globally after countries eased Covid-19 social distancing rules that kept other illnesses largely at bay.

The “twindemic”, as the tandem waves of Covid-19 and influenza have been termed, stands to get worse in China, which saw years of some of the world’s strictest measures, followed by one of its fastest pivots back to normal life.

China’s unexpected rush to dismantle nearly all pandemic restrictions in early December 2022 unleashed the world’s biggest Covid-19 outbreak, with nearly 90 per cent of the country’s 1.4 billion population infected in less than two months.

While the reopening wave appears to have ebbed, the government still reports about 10,000 Covid-19 cases each day that are confirmed by laboratory tests.

While lockdowns and mass testing have eased as China moves on from its zero-Covid policy, the authorities still allow schools to halt in-person teaching – either by individual grade level or for the entire campus – to prevent wider outbreaks caused by Covid-19 and other infectious diseases.

It was not unusual for schools to pause classes even before Covid-19, when flu and other pathogens to which children are particularly susceptible triggered student clusters.

Health officials in Beijing said on Wednesday that they were seeing outbreaks of flu and norovirus in February, mostly at schools and kindergartens.

Cases of influenza are also creeping up as pre-pandemic normality returns. China’s flu positivity rate jumped to 3.4 per cent from 0.7 per cent in the week ending Feb 12.

The Chinese Centre for Disease Control and Prevention also warned of outbreaks of norovirus, which causes fever, vomiting and diarrhoea; hand, foot and mouth disease; and chicken pox, all of which might easily erupt in schools as students mingle indoors. BLOOMBERG
