Whooping cough cases in China surged more than 20-fold in the first two months of 2024 compared to the same period in 2023, highlighting the ongoing risk of this highly contagious respiratory disease in the country.
Chinese health authorities do not mandate or provide booster shots for whooping cough, leading to concerns about waning vaccine-induced immunity as children reach adolescence. Discussions are ongoing to consider updating the vaccine or adjusting the immunization program.
After a decline during the Covid pandemic, whooping cough infections rose to almost 40,000 cases annually in 2022 and 2023 in China. Factors such as Covid disruptions, waning immunity, and genetic changes are seen as contributors to the increase.
