👉 An infection weapon is a biological agent designed to cause disease and harm when introduced into a host, often through vectors like insects or contaminated surfaces. These pathogens are engineered to exploit the host's immune system, leading to severe symptoms and potentially fatal outcomes. The weaponization of such agents involves genetic manipulation to enhance virulence, transmission efficiency, or resistance to treatments, making them particularly dangerous. This concept highlights the dual-use nature of biotechnology, where tools for medical research can be repurposed as weapons, posing significant risks to global health security.
