WHO wants more data after China hospitals overwhelmed by children with pneumonia

THE World Health Organization (WHO) has asked China for detailed information about a surge in respiratory illnesses in children, including pneumonia, as top paediatric medical centres across the country are overwhelmed with patients. 

The WHO cited reports, including one this week from ProMED, which tracks outbreaks of infectious diseases around the world, warning of an “undiagnosed pneumonia in children in northern China”. The international health body has requested additional epidemiological and clinical information and test results from Chinese officials, it said in a statement on Wednesday (Nov 22).

The resurgence of several respiratory pathogens come as China heads into its first winter after easing stringent Covid-19 pandemic restrictions, and appears to have hit children particularly hard. 

“It is unclear if these are associated with the overall increase in respiratory infections previously reported by Chinese authorities, or separate events,” the WHO said. 

Local media have reported a steady rise in infections from a pathogen called mycoplasma among kindergarten and primary school children. While the germ tends to cause only mild colds in older kids and adults with robust immune systems, younger children are prone to develop pneumonia – with symptoms lasting for weeks.

Data from the Chinese Centre for Disease Control and Prevention also showed the influenza positivity rate climbing steadily in October, even as Covid rates continued to trend down following a small peak over the summer. 

Beijing Chaoyang Hospital, China’s top medical centre for respiratory diseases, has seen the mycoplasma positivity rate among children rise to 40 per cent – compared with just 6 per cent among adults – the hospital’s vice-dean Tong Zhaohui said at a briefing in the city last week. Mycoplasma tends to cause major outbreaks every three to seven years, he warned. 

The National Health Commission (NHC), China’s top health regulator and which also oversees hospitals across the country, is boosting local clinics’ capability to treat infections and identify critical illness in a bid to ease pressure on some top hospitals, state news agency Xinhua reported on Thursday, citing an NHC official it did not identify.

While China has a tiered healthcare system with community clinics serving as the primary medical service provider for residents, many patients tend to seek care at prestigious hospitals and medical centres in big cities as a referral is not required.

Already, more people are masking up on Beijing’s busy subway trains, while teachers in the city have pleaded with parents to not send their kids to school should they display any symptoms. 

Potentially fuelling concerns, the most common antibiotic used to treat mycoplasma infections faces higher drug resistance in China versus elsewhere in the world. 

Up to 60 per cent to 70 per cent of adult cases and up to 80 per cent of cases in kids do not respond to the drug, azithromycin, and others in the same class of antibiotics, Yin Yudong, an infectious disease doctor at Chaoyang, told Beijing News earlier this month. 

That has sparked a rush by anxious parents to top children’s hospitals in some Chinese megacities. Local media reports have showed several prestigious paediatric medical centres in Beijing teeming with parents and sick kids, while the time it takes for families to see an emergency room doctor has in some cases stretched to more than seven hours.

The local branches of China’s CDC in Beijing and nearby Tianjin said mycoplasma infections have peaked, while other illnesses such as flu and respiratory syncytial virus are on the rise, state media including CCTV reported. BLOOMBERG
