As an infectious disease epidemiologist, could you elaborate on that? What is it that makes it so contagious?

As an infectious disease epidemiologist, could you elaborate on that? What is it that makes it so contagious?
- Fomite 8y agoA couple reasons: - While it enters via the lungs, the virus emerges in the trachea, which positions it really well to be aerosolized through coughing. This aerosol and droplet transmission is really efficient. - Measles is relatively stable in the environment, so lingers for a fair amount of time. - It also appears to have a relatively small infectious dose. Other highly contagious diseases, like norovirus, share fairly similar properties - you make a lot of virus, it hangs out for awhile, and you don't need to come in contact with much of it. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4997572/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4997572/
