Pneumonia spike in China: What we know so far

A year after relaxing stringent Covid-19 restrictions, China is facing its inaugural winter with a notable surge in cases of respiratory illness. China has initiated monitoring of mycoplasma pneumonia, alongside continued tracking of flu, RSV, and SARS-CoV-2 trends. The World Health Organization recognizes the scarcity of available information but anticipates a rise in respiratory illnesses with the onset of winter.

The WHO, having sought disease-related information from the Chinese government, has verified the absence of any novel pathogens in the reported cases.

The State Council, on the other hand, has foreseen an expected surge in influenza cases during the upcoming winter and spring seasons. It also anticipates sustained levels of mycoplasma pneumonia infections in specific regions. The council underscored the significance of robust reporting mechanisms for infectious diseases, emphasizing that all regions should enhance their efforts to ensure timely and accurate information reporting on such diseases.

Here is all you need to know:

Symptoms of Pneumonia

• Pneumonia is a respiratory infection that inflames the air sacs in one or both lungs, causing them to fill with pus or other fluids. It can be caused by various pathogens including bacteria, viruses or fungi.
• Individuals with pneumonia may experience difficulty in breathing or shortness of breath, especially during physical activity.
• Chest pain is another prevalent symptom, often described as sharp or stabbing and intensified with deep breaths. 
• Fever, sometimes with sweating and chills is a frequent indicator of the body's immune response to the infection.
• Additionally, fatigue and a general sense of weakness may accompany pneumonia as the body expends energy in combating the respiratory infection.

First cases of pneumonia and overcrowded hospitals in China

• On November 21, the ProMED infectious disease monitoring network highlighted a Chinese news report stating that hospitals in Beijing and other areas were grappling with a surge of undiagnosed pneumonia cases. 
• The increase was particularly pronounced among children in the northern areas like Beijing and Liaoning province, leading to longer waiting times in hospitals. This in turn raised alarm about a potential emerging pandemic, prompting the WHO to seek additional information from China on November 22. 
• China is advising vigilance in response to an upswing in respiratory illnesses, especially within educational institutions and healthcare facilities.
• Experts from across the globe have suggested that the surge is most likely due to poor immunity in children due to end of Covid restrictions. The arrival of winters is also one of the major reasons, as per the reports.

Warnings from health authorities

• While the WHO has requested information from China on pneumonia outbreak, Beijing has assured that no critical cases have been detected.
• The WHO has recommended people specifically in the affected areas to follow precautions. This includes, taking precautions against respiratory illness, isolation if affected, wearing a mask and getting tested.
• It has also advised restrictions on travelling to China, considering the current situation.

How can we prepare?

Any country can be prepared for exigency that may emerge from the current influenza situation in China. The main focus should be on monitoring the outbreak of H9N2 avian influenza and respiratory illness clusters among children in China. Adopting measures to reduce the risk of infection and recognizing symptoms early for prompt medical attention can be very beneficial for all the countries.

Here are several steps to help you be prepared:

1. Vaccination: Stay up-to-date with vaccinations, particularly the pneumonia vaccine which protects against specific bacteria that can cause pneumonia.
2. Good hygiene practices: Practice good hygiene by frequently washing your hands with soap and water, especially after coughing or sneezing. If soap and water are not available, use an alcohol-based hand sanitizer.
3. Avoid smoking: Smoking damages the lungs and weakens the immune system, making individuals more susceptible to respiratory infections.
4. Prompt medical attention: If you or someone you know develops symptoms such as persistent cough, difficulty breathing, chest pain, fever, or fatigue, seek medical attention promptly. Early diagnosis and treatment are vital for managing pneumonia effectively.
5. Stay informed: Stay informed about respiratory infections and outbreaks in your community. Follow public health guidelines and take necessary precautions, such as wearing masks in crowded places during respiratory virus seasons.
