The boundary between contagious and non-contagious infectious diseases is not perfectly drawn, as illustrated classically by tuberculosis, which is clearly transmissible from person to person, but was not classically considered a contagious disease.he non-contagious category of infections usually require a special mode of transmission between persons or hosts. These include need for intermediate vector species (mosquitoes that cause malaria) or by non-casual transfer of bodily fluid (such as transfusions, needle sharing or sexual contact).
Chlamydia pneumoniae is considered to be contagious between people. Generally the infectious agent may be transmitted by saliva, air, cough, fecal-oral route, surfaces, blood, needles, blood transfusions, sexual contact, mother to fetus, etc. Chlamydia pneumoniae, although infectious, is not a genetic disease.It is not caused by a defective or abnormal gene. The contagious disease, Chlamydia pneumoniae, can be transmitted: 1  from person to person by saliva, air, coughing, contact, surfaces, fecal-oral route, etc.bout contagion and contagiousness: Contagion and contagiousness refers to how easily the spread of Chlamydia pneumoniae is possible from one person to another. Other words for contagion include infection, infectiousness, transmission or transmissability.
