Your Son Comes Home from School Complaining That He Is

question 33

Multiple Choice

Your son comes home from school complaining that he is ill. He tells you he thinks he has the flu—he has a sore throat, runny nose, and a cough, and his eyes are very red. Everyone in your family received a influenza vaccine about a month ago, and as the CDC reports that this year's vaccine is approximately 70% effective, you think it is unlikely that your son does in fact have this disease. In addition, your son does not seem to have muscle aches or a headache, which generally occur with flu. Nonetheless, he does look ill and when you take his temperature, you find that he has a fever of 38.9^oC. You take him to see his doctor, because you suspect that while your son likely does not have influenza, he also does not have a common cold.
-You ask the doctor whether there is a vacccine that your children can be given to prevent further adenoviral infections. He tells you

• A) that there is no need for a vaccine because your son can be treated with antibiotics AND that adenovirus infections can be avoided by handwashing.
• B) there is a vaccine against two adenovirus serotypes but this is only given to military recruits AND that adenovirus infections can mostly be avoided by handwashing.
• C) there is a vaccine against two adenovirus serotypes but this is only given to healthcare personnel BUT that adenovirus infections are easily treated with antibiotics.
• D) it is not possible to generate vaccines against any double-stranded DNA viruses AND that adenovirus infections can be avoided by handwashing.
• E) it is not possible to synthesize vaccines for preventing diseases caused by RNA viruses BUT that adenovirus infections can be prevented with prophylactic antibiotics.
