What is it about?
Our article is about finding out what percent of college students new to campus were carriers of meningococcus (the bacteria that causes meningitis) and whether it increased over the course of a semester.

Why is it important?
It is important because, although meningococcus lives in the back of some people's throats, it is the bacterium that can kill a young healthy college student in 36 hours. It is also important because the value can change over time, especially with the introduction of new vaccines for types ACWY and type B over time. In addition, no recent study had been performed since COVID-19.
Perspectives
The vaccine for types ACWY is much more common for young adults before they attend college, while the type B vaccine is usually just given to young adults with a decreased immune system. The overall carriage value was less than previous studies. There was no student carrier of type ACWY, which supports the possible (and likely) influence of the vaccine. The value did increase over the semester with certain risk factors: being a 2nd-year student, living on campus for the second year, smoking/vaping, kissing and sexual contact.
