China says a surge in respiratory illnesses is caused by flu and other known pathogens

China: Flu, other known pathogens cause recent respiratory illness clusters; WHO requests data; Chinese authorities advise people to wear masks, focus on preventing spread in crowded places.

A surge in respiratory illnesses across China that has drawn the attention of the World Health Organisation is caused by the flu and other known pathogens and not by a novel virus, the country's health ministry said on November 26.

Recent clusters of respiratory infections are caused by an overlap of common viruses such as the influenza virus, rhinoviruses, the respiratory syncytial virus, or RSV, the adenovirus as well as bacteria such as mycoplasma pneumoniae, which is a common culprit for respiratory tract infections, a National Health Commission spokesperson said.

The ministry called on local authorities to open more fever clinics and promote vaccinations among children and the elderly as the country grapples with a wave of respiratory illnesses in its first full winter since the removal of COVID-19 restrictions.

“Efforts should be made to increase the opening of relevant clinics and treatment areas, extend service hours and increase the supply of medicines,” said ministry spokesman Mi Feng.

He advised people to wear masks and called on local authorities to focus on preventing the spread of illnesses in crowded places such as schools and nursing homes.

The WHO earlier this week formally requested that China provide information about a potentially worrying spike in respiratory illnesses and clusters of pneumonia in children, as mentioned by several media reports and a global infectious disease monitoring service.

The emergence of new flu strains or other viruses capable of triggering pandemics typically starts with undiagnosed clusters of respiratory illness. Both SARS and COVID-19 were first reported as unusual types of pneumonia.
