A small public school in northern California experienced an outbreak of pertussis (whooping cough). Pertussis was observed to develop in 31 of 96 unvaccinated children, 26 of 489 vaccinated children, and 14 of 67 children with unknown vaccination status. Are the unvaccinated students and those of unknown vaccination status at higher risk of pertussis? Calculate the appropriate measure of excess risk for the unvaccinated students versus the vaccinated students and for those with unknown vaccination status versus the vaccinated students (i.e., the vaccinated students are the unexposed). Interpret your results in plain language.

Bordetella pertussis, the bacterial species that causes Whooping cough, has several virulence factors. They include: Filamentous Hemagglutinin (an adhesin), Fimbriae, Pertussis toxin, and Tracheal cytotoxin. Based on what you know about how infections work, what are the roles of these virulence factors? Which are defensive and which are offensive? (you do not have to identify exactly what each of these virulence factors do – but identify what kind of virulence factor they are).

Imagine your class has been hired to secure the network of a relatively small public school system. The system's network(s) includes administrative offices, classroom computers, Web servers, e-mail servers, and other typical features. Your class decides that multiple layers of firewall protection are required. As a group, discuss the firewall options described in this chapter and decide which ones to use. Where would you place each type of firewall, and why?
