The World Health Organization (WHO) declared an end to its global health emergency over the spread of the Zika virus on Friday, prompting dismay from some public health experts confronting the epidemic. An agency advisory committee said it ended the emergency—formally known as a Public Health Emergency of International Concern—because Zika is now shown to be a dangerous mosquito-borne disease, like malaria or yellow fever, and should be viewed as an ongoing threat met as other diseases are, sometimes with WHO help. - "Zika Is No Longer a Global Emergency, WHO Says," Donald G. McNeil Jr. Why would public health experts be worried about this declaration from the World Health Organization? People will let their guard down and not take precautions to prevent the spread of the Zika virus. People will no longer be infected with the Zika virus but will seek health care anyway. More money will be spent on discovering a Zika vaccine instead of more serious diseases. Communities will promote health awareness outreach about Zika transmission.

A. People will let their guard down and not take precautions to prevent the spread of the Zika virus.

A cholera outbreak has occurred, and the culprit is contaminated drinking water. Which controllable risk factors might have caused this outbreak? Check all that apply. The unsanitary handling of human waste by nearby waterways. The genetic makeup of individuals reporting cholera-related symptoms. The significant difference in reported cases between males and females. The reduction in accessibility to regions that use filtered bottled water. The lack of access individuals with symptoms have to health clinics.

A. The unsanitary handling of human waste by nearby waterways. D. The reduction in accessibility to regions that use filtered bottled water. E. The lack of access individuals with symptoms have to health clinics.

Page 1: Tia is studying the effects of disease on public health. She begins by looking at the spread of hepatitis B. She would like to examine how the causes and the consequences of this infectious disease are related. Help her complete the following flow chart. Page 2: A flowchart. Box 1 reads, Hepatitis B is a pathogen found in bodily fluids. Box 2 reads, Item number 2. Box 3 reads, People spread hepatitis B to others after infection. What did Tia enter in item #2 of the flowchart to further explain the process of a hepatitis B infection? This pathogen spreads through childbirth or close physical contact with an infected person. People with strong immune systems fight hepatitis infections more easily. This pathogen infects people who practice safe food handling practices. Genetic makeup places some people at risk for contracting hepatitis.

A. This pathogen spreads through childbirth or close physical contact with an infected person.

In a small town, Ruben is stunned after reading about the global spread of the Ebola virus. He decides it is time to take action to prevent future outbreaks from occurring within his own community. In 2016, Ruben puts together a pamphlet that educates people about Ebola. To validate his information, he uses the following source: CDC (Centers for Disease Control and Prevention). 2016. "2014-2016 Ebola Outbreak in West Africa." https://www.cdc.gov/vhf/ebola/outbreaks/2014-west-africa/. Accessed June 2016. Why is Ruben confident that this is a reliable source? The source contained advertisements of promotional products. The source focused solely on the global spread of other diseases. The information was provided by a governmental source. The author of this source had limited training in public health and policy.

C. The information was provided by a governmental source.

The World Health Organization reports that more than 70 countries have reported cases of Zika infection. As a public policy expert, you record and publish this information. In addition, part of your job is to create effective strategies that can be implemented to minimize disease outbreak. If the number of cases reported doubled in three months, what is the best immediate action to recommend? surveying and reporting the number of Zika-related cases distributing mosquito spray at future local health fairs instituting a public ban on traveling to and from Zika-prone countries instructing doctors to tell every patient not to travel

C. instituting a public ban on traveling to and from Zika-prone countries

Which pathogen causes influenza? bacteria protozoan virus parasite

C. virus

Giardia infection is an intestinal infection that causes cramps, nausea, and diarrhea. It is caused by a parasite and is one of the most common waterborne infectious diseases in the United States. Tia knows that giardia is a pathogen found in fecal matter. The parasite is often found in streams, swimming pools, spas, and municipal water supplies. To help her community prevent the spread of giardia in the future, Tia wants to suggest a preventive measure to public officials in her community. What preventive measure should Tia share with public officials in her community that effectively targets her goal to prevent the spread of giardia? Research how giardia infects the human body. Monitor trends in the growth of giardia populations. Identify the symptoms associated with this infection. Enact measures to test city pools more frequently.

D. Enact measures to test city pools more frequently.

Page 1: In the United States, people infected with the West Nile virus was recorded from 1991-2008. The accompanying map shows the number of cases reported for those infected with the virus. Page 2: A map of the United notes with a key of various shades of blue that note the average annual cases per 100,000 people with white equaling no cases and the darkest blue equal 2.5 or more. The Midest has the darkest notes. This map represents ___________ West Nile virus over time. The map shows that regions such as the ___________ experienced ____________the West Nile virus after residents were infected with the disease following a mosquito bite.

✔️ the national spread of ✔️ Midwest ✔️ a high transmission of
