India steps up surveillance of influenza cases as 'COVID-like' virus spreads across China

India's National Centre for Disease Control (NCDC) has stepped up its surveillance of respiratory and seasonal influenza cases amid unconfirmed reports of a possible human metapneumovirus (HMPV) outbreak in China.

"We will continue to monitor the situation closely, validate the information, and update accordingly," news agency ANI quoted official sources as saying.

It is also in touch with international agencies over the matter.

China's new system to monitor unknown pneumonia

The sources were quoted as saying that an update from the Western Pacific Region of the World Health Organization (WHO) noted an increase in acute respiratory infections between December 16-22. These include seasonal influenza, rhinovirus, respiratory syncytial virus (RSV), and HMPV.

However, the overall scale and intensity of these diseases in China are lower than last year.

In anticipation of the expected surge of respiratory diseases in winter, China has introduced a pilot system to monitor pneumonia of unknown origin.

Health crisis

Reports indicate that hospitals and crematories in China are struggling with a rise in respiratory illnesses, especially HMPV.

Children's hospitals are particularly inundated with a rise in pneumonia and "white lung" cases.

In late December 2024, Chinese authorities had announced a monitoring system for unknown pneumonia cases to be better prepared than five years ago when COVID-19 first emerged.

Reporting procedures for unknown diseases

Additionally, the National Disease Control and Prevention Administration in China will establish reporting procedures for laboratories.

As part of this new protocol, disease control agencies will verify and handle such cases, media reports said.

Kan Biao from China's disease control authority was quoted as saying that various respiratory infectious diseases are expected during winter and spring but added that the total number of cases this year would be lower than the previous year.
