Increase in Respiratory Diseases in China; WHO Requests More Information

The World Health Organization (WHO) has requested China to provide information regarding the rise in respiratory diseases and pneumonia among children in the country. The organization emphasized that such requests from countries are a common procedure. Chinese health officials had previously announced on November 13 that the incidence of respiratory diseases in the country has increased. They attributed this rise to the "lifting of COVID-19 restrictions" and the circulation of known pathogens such as influenza, mycoplasma—which typically affects younger children—respiratory syncytial virus (RSV), and the virus causing COVID-19. Both China and the WHO have faced criticism regarding transparency in reporting the initial cases of COVID-19 in Wuhan in late 2019. The WHO stated that groups like the Emerging Diseases Surveillance program (ProMED) have reported clusters of undiagnosed pneumonia in children in northern China. However, it remains unclear whether these cases are related to the overall increase in respiratory infections previously reported by Chinese officials or if they are separate events. The WHO has called for more information regarding the rise in respiratory diseases and the reported clusters of pneumonia in children, and China is expected to respond to this request within 24 hours. The increase in respiratory diseases in China occurs as the country begins its first winter since the lifting of strict COVID-19 restrictions. Epidemiologists suggest that due to COVID-19 restrictions, immunity levels against respiratory viruses may be lower than normal, leading to an increase in infections. For young children, quarantine has delayed their first exposure to common pathogens. Many other countries have also faced a similar rise in respiratory diseases following the easing of restrictions. The WHO had announced in late October that northern China is experiencing an increase in flu-like illnesses compared to the same period in the past three years and has established systems to provide data and information on disease trends on international monitoring platforms. Recently, media outlets in cities like Xi'an in northwestern China have published videos of hospitals filled with sick children. The WHO has advised the people of China to take measures to reduce the risk of respiratory disease transmission. These measures include vaccination, maintaining distance from sick individuals, staying home when ill, testing and seeking medical care as needed, wearing masks when necessary, ensuring good ventilation, and regular handwashing.
