A growing debate questions how toxins and environmental exposures contribute to illness. Some researchers argue that chemical stress on cells can cause them to release exosomes—tiny signaling particles the body uses during injury or inflammation. Because exosomes can resemble viruses under a microscope, some claim this overlap complicates diagnosis and may blur the line between toxic exposure and infection. The discussion raises important questions about environmental health, testing accuracy and how the body reacts to stress.
