Typhoid in India: An Age-old Problem With an Existing Solution.

Area of Science:

• Public Health
• Infectious Diseases
• Epidemiology

Background:

• Enteric fever remains a significant global health concern, particularly in regions with poor water and sanitation infrastructure.
• South Asia, especially India, faces a substantial burden of typhoid and paratyphoid fever, yet precise incidence and economic impact data are limited.
• Existing knowledge gaps hinder targeted public health interventions and resource allocation for enteric fever in India.

Purpose of the Study:

• To quantify the incidence, severity, and cost of illness associated with enteric fever in India.
• To provide contemporary data on the disease burden of typhoid and paratyphoid fever.
• To inform public health strategies and interventions for enteric fever control in India.

Main Methods:

• Conducted a multi-site surveillance study within the Surveillance for Enteric Fever in India (SEFI) network.
• Collected data over two years, from October 2017 to February 2020.
• Analyzed incidence, disease severity, and patient-incurred costs of enteric fever.

Main Results:

• Demonstrated a high contemporary disease burden of enteric fever in India.
• Revealed substantial costs of illness, largely borne by patients due to limited universal healthcare coverage.
• Highlighted the ongoing public health challenge posed by typhoid in India, even amidst other health priorities.

Conclusions:

• Enteric fever represents a significant and costly public health problem in India.
• The findings underscore the need for continued focus on typhoid prevention and control.
• Typhoid conjugate vaccines, readily available from Indian manufacturers, present a crucial and accessible tool for mitigating this burden.
