What do you know about infectious disease?
Which of these viral diseases has the most antiviral drugs available to treat it?
-
Sorry, that’s incorrect.
Today there are more antiviral drugs available for HIV than for any other viral disease, transforming an infection that was once considered a death sentence into a manageable chronic condition.
-
Correct!

True or False: Not all microbes are harmful to humans.
-
Correct!
Not all microbes are harmful to humans. In fact, many of them protect us, helping our bodies function properly and competing with harmful organisms in an eternal contest for habitable space in or on our bodies. Although the microorganisms that cause disease often receive more attention, most microorganisms do not cause illness.

Public health officials can identify the outbreak of disease by monitoring certain patterns of behavior through syndromic surveillance. Which of the following is one of the signs used to identify a disease outbreak using this system?
- Level of school and work absenteeism
- Sales of over-the-counter medication
- Number of illness-related 911 calls
- All of the above
-
Sorry, that’s incorrect.
In syndromic surveillance, all of the above are used in addition to other patterns that suggest an outbreak. Despite the emergence of this innovative surveillance method, most surveillance still depends on tracking reported infections.

True or False: The only way public health agencies can deal with infectious disease is to have good surveillance in place, wait for an outbreak to happen in a human population, and then rush to contain it.

By identifying pathogens in the animals where they naturally live and monitoring those organisms as they move from animals into people, it may be possible to prevent deadly new infections of animal origin from entering and racing through human populations.

Which of the following is NOT a type of infectious agent?
-
Sorry, that’s incorrect.
White blood cells are not a type of infectious agent. Part of the immune system, white blood cells fight infection rather than cause it.

True or False: Antibiotics work by introducing an agent that resembles a disease-causing microbe, thus stimulating the body's immune system to recognize it as foreign, destroy it, and "remember" it, so that it can more easily identify and destroy any similar, disease-causing microbes that it later encounters.
-
Sorry, that’s incorrect.
The above describes how vaccines work. Antibiotics work by either killing bacteria or stopping them from reproducing, allowing the body's natural defenses to eliminate the pathogens.
