Pertussis in Latin America: current situation and future vaccination challenges

Area of Science:

• Infectious Diseases
• Epidemiology
• Public Health

Background:

• Pertussis (whooping cough) is a major cause of vaccine-preventable deaths in children under five worldwide.
• While well-studied in developed nations, the epidemiology of pertussis in Latin America remains largely unknown.
• This lack of data hinders effective control strategies in the region.

Purpose of the Study:

• To review and synthesize recent literature on pertussis epidemiology in Latin America and the Caribbean.
• To identify critical issues including disease awareness, surveillance, and vaccination challenges.
• To provide a comprehensive overview of the current pertussis burden in the region.

Main Methods:

• Systematic review of published literature on pertussis in Central and South America and the Caribbean.
• Analysis of epidemiological data, disease awareness, surveillance systems, and vaccination strategies.
• Identification of research gaps and future directions.

Main Results:

• Pertussis continues to cause significant morbidity and mortality in Latin America.
• Disease awareness and epidemiological surveillance are often inadequate.
• Vaccination challenges, including access and vaccine effectiveness, require further investigation.

Conclusions:

• Urgent need for improved pertussis surveillance and disease awareness in Latin America.
• Addressing vaccination challenges is crucial to reduce the burden of pertussis.
• Further research is needed to fully understand and control pertussis in the region.
