FLEAS AND FLEA-BORNE DISEASES IN SINGAPORE: DIVERSITY, TRENDS, AND FUTURE DIRECTIONS

Area of Science:

• Veterinary Entomology
• Public Health
• Infectious Diseases

Background:

• Fleas and flea-borne diseases are neglected public health concerns in Singapore.
• Research on vectors like mosquitoes and ticks is more prevalent than on fleas.
• This study addresses the knowledge gap concerning flea-borne diseases in Singapore.

Purpose of the Study:

• To examine trends in flea-borne rickettsiosis in Singapore from 2016-2022.
• To document new flea species and host associations in Singapore.
• To provide a roadmap for future research and public policy on flea-borne diseases.

Main Methods:

• Analysis of epidemiological data for flea-borne rickettsiosis (2016-2022).
• Entomological surveys to identify flea species and their hosts.
• Literature review and synthesis of current knowledge on flea diversity and diseases.

Main Results:

• Flea-borne rickettsiosis cases are predominantly locally acquired.
• Affected demographics include males, migrant workers, and individuals aged 15-34.
• New records include Thaumapsylla breviceps and Ctenocephalides felis from new hosts.

Conclusions:

• Flea-borne diseases, particularly rickettsiosis, pose a significant public health risk in Singapore.
• Enhanced surveillance and research are crucial for effective control.
• The study provides a foundation for targeted interventions and policy development.
