Virus transmission is the process by which viruses are spread from one person to another, or from one host to another. This can occur through various means, including direct contact with infected individuals, through respiratory droplets, through contaminated surfaces or objects, and through bodily fluids. Understanding how viruses are transmitted is important for implementing effective public health measures to control the spread of infectious diseases. Researchers study virus transmission to identify the most common routes of transmission, risk factors for transmission, and to develop strategies for prevention and control. This research area often involves interdisciplinary collaboration between epidemiologists, virologists, microbiologists, and public health experts.
