For each child who dies from pneumonia in an industrialized country, about how many children die from the infection in developing countries?
-
Sorry, that’s incorrect.
Life-saving vaccines and medications aren’t distributed equitably around the world; for each child who dies from pneumonia in an industrialized country, more than 2,000 children die from the infection in developing countries.

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.

Which of the following is needed to help improve the public health situation in developing countries?
- More safe water supplies
- Better sewage treatment and disposal
- Improved food safety and vaccination programs
- All of the above
-
Sorry, that’s incorrect.
All of the above are urgently needed in developing nations. A major barrier to achieving these improvements is the underlying weakness of health systems in resource-poor countries, including a shortage of health workers and a lack of disease surveillance programs.

Which is the vector (animal that carries the pathogen) for West Nile virus?

Sorry, that’s incorrect.
The mosquito is the vector for West Nile virus. The mosquito suffers no ill effects from the virus but transmits it to humans and other warm-blooded creatures (such as crows) when it takes a blood meal.

Which deadly pathogen cannot be found naturally in the wild:
-
Sorry, that’s incorrect.
Smallpox cannot be found naturally in the wild. Smallpox was officially declared eradicated from the globe in 1980, after an 11-year WHO vaccination campaign—the first human disease to be eliminated as a naturally spread contagion. Today, the virus remains only in laboratory stockpiles.

Which of the following is an effective way to protect yourself against infectious disease?
- Keep immunizations up to date
- Wash your hands often
- Prepare and handle food carefully
- All of the above
-
Sorry, that’s incorrect.
All of the above can help prevent infectious disease. Other behaviors, such as exercising caution around wild and unfamiliar domestic animals, avoiding insect bites, practicing safe sex, and being vigilant about disease threats while traveling abroad, can also reduce the risk of infection.
