indian Opinion Analysis
The study underscores an important dimension in managing public health and disease control strategies-targeting interventions based on susceptibility differences among age groups could be critical for India’s diverse population structure. With a notable proportion of the Indian population being young, such findings may influence planning for healthcare services or preventive measures during outbreaks. Additionally, understanding how juveniles contribute to disease dynamics could inform policies in agriculture and wildlife conservation too.
