Answer to Question 1

ANS: D
Antiinfective drugs, such as antibiotics, antivirals, antiretrovirals, and antimalarials, play important roles in controlling infectious diseases. Not only do they permit recovery of the infected person, but they also play a major role in preventing transmission of the pathogens to another. The first step in preventing transmission of tuberculosis and syphilis is to treat the infected person with antibiotics. Because the question asks about further spread, infection in a person has been diagnosed, so education is needed, but it is too late for that person. Adults not in school also are infected with STDs. A stronger, more effective sanitizing agent would not be the most effective strategy to prevent spread of STDs.

Answer to Question 2

ANS: C
Quarantine is an enforced isolation or restriction of movement of those who have been exposed to an infectious agent during the incubation period; this is another method of controlling the reservoir. Quarantine was used effectively during the outbreak of SARS in 2003, when some hospitals required that their staff exposed to SARS patients remain at the hospital until proved to be symptom free at the end of the incubation period. Immunization and screening would not protect the population from exposure to this infectious disease. It is likely that others besides tourists could be exposed or infected by this disease, thus, closing airports would be ineffective in controlling the spread of the disease.
