Thank you for your responses as it helps me to better understand your situation. Unfortunately it is impossible to determine if someone with Schizophrenia is sole cause of someone else's illness or not as people are exposed to so many different situations everyday that can cause symptoms like the common cold (e.g. stuffy nose) nausea, fever, etc...There are just too many virulent and bacterial elements in our society that can be a cause for these relatively common and non-specific symptoms, so there is no conclusive study to say that Schizophrenia or someone with Schizophrenia is a cause for this. All that has been researched on Schizophrenia dealing with infectious and virulent elements is that 1)Poor hygiene can lead to a higher incidence rate of becoming exposes to common infectious agents and being a carrier of such agents. Individuals who do not wash their hands regularly or bathe regularly could be more infectious than the average person. Because individuals with Schizophrenia have much higher rates of poor hygiene than it is likely that someone with Schizophrenia will be able to pass infectious agents to others at a higher degree.
2) The only other issue with Schizophrenia and infectious agents is that there is a higher incidence rate of individuals with Schizophrenia being diagnosed with variations of Herpes viruses, endogenous retroviruses, and Toxoplasma gondii. There is some speculation that this can cause disorders like Schizophrenia or Bipolar
Disorder, but individuals with these types of infectious agents could also have non-descriptive symptoms like you mentioned. If you have one or more of these diseases than it is possible you could be passing these infectious agents to others. Here are a couple studies on this if you want to learn more:
