Infectious diseases remain a major public health challenge, requiring effective surveillance, prevention, early diagnosis, vaccination strategies, and coordinated healthcare responses. Primary healthcare plays a vital role in controlling communicable diseases through immunization programs, antimicrobial stewardship, outbreak preparedness, health education, and community-based interventions. Emerging infectious diseases, antimicrobial resistance, and global pandemics highlight the need for resilient healthcare systems and innovative disease prevention strategies. This session invites researchers, infectious disease specialists, microbiologists, epidemiologists, immunologists, public health professionals, and healthcare providers to present cutting-edge research, clinical advances, and evidence-based approaches that strengthen infectious disease prevention, vaccination, and global health security.
