Amoebic Dysentery - China, 2005-2019.

Area of Science:

• Infectious Diseases
• Public Health
• Epidemiology

Background:

• Amebiasis is caused by *Entamoeba histolytica*.
• Amoebic dysentery is a severe form of amebiasis, monitored by China's National Notifiable Disease Reporting System.

Purpose of the Study:

• To analyze the epidemiological trends of amoebic dysentery in China from 2005 to 2019.
• To identify key demographic and geographic factors associated with amoebic dysentery incidence.

Main Methods:

• Retrospective analysis of national surveillance data.
• Calculation of incidence rates and identification of trends over time.
• Geographic and age-based case distribution analysis.

Main Results:

• A total of 28,229 cases and 7 deaths were reported between 2005 and 2019.
• The annual incidence rate of amoebic dysentery declined significantly from 0.26/100,000 in 2006 to 0.06/100,000 in 2019.
• Most cases were concentrated in southern China and among pediatric populations.

Conclusions:

• Amoebic dysentery incidence has substantially decreased nationwide in China.
• Continued public health interventions are crucial for further control.
• Targeted strategies for southern regions and children are recommended for high-priority interventions.
