- There are no longer any cases of deadly smallpox in the world becausearrow_forwardThe World Health Organization has announced the complete eradication of smallpox and is working to the eradication of measles and polio. Why would vaccination be more likely to eradicate a viral disease than a bacterial disease? Why can polio be eradicated but not influenza? Give reference.arrow_forwardYou compared epidemiological data from two different outbreaks. You found that the outbreak caused by Virus-123 in City A spread much more rapidly than the outbreak caused by Virus-678 in City B. Briefly describe three factors that might have differed between these outbreaks.arrow_forward
- In 2019, a couple died from plague after eating uncooked rodent spleen (a delicacy where they were traveling). Any exposure to fleas can lead to plague, but it is most commonly transmitted by fleas from rodents/prairie dogs/squirrels. For the decades it has been known about, Ebola (and many of these other hemorrhagic viruses) have been contained to rural villages. After 2000, they began to spread into urban areas, from which they can launch into epidemics and pandemics. The index (first) case of Ebola in urban areas of Congo (May 2018) was the first sign of an urban Ebola epidemic that raged for more than a year, with about 2000 confirmed cases. Which symptom set characterizes these viruses in particular? high fevers sore throat clotting problemsarrow_forwardWhen doctors first discovered that the virus was Zika, they felt relieved because Zika outbreaks had always been mild in the past. True Falsearrow_forwardConsidering that CMV infects 50% of the adult population in the United States and 100% of the population in many other countries, why is there so little Cytomegalovirus disease in the world?arrow_forward
- On 17 August 2022, the Ministry of Health of the Democratic Republic of Congo (DRC) reported a confirmed case of Ebola virus in the Beni district of North Kivu province. As an epidemiologist, describe the steps you would recommend to prevent further spread of the virus in the local area,as well as to neighboring countries.arrow_forwardHere are three different methods that were used to protect people from smallpox: 1. Blowing ground-up scabs into a person’s nostrils.2. Scratching fluid and puss from smallpox pustules into a person’s skin.3. Injecting a virus related to the smallpox virus. a. What does each method have in common with the others? b. What is one difference between the three methods?arrow_forwardIn the 1960s when polio vaccines were first administered in the United States the oral polio vaccine (OPV) was used. Explain why since 2000 the CDC now recommends the use of the injected polio vaccine (IPV) instead of the OPV.arrow_forward
- Why can bird flu H5N1 infect humans?arrow_forwardWhich of the following statements reflects the pathogenesis of influenza virus? A-The virus frequently establishes persistent infections in the lung B-Viremia is common C-The virus enters the host in airborne droplets D-Viral infection does not kill cells in the respiratory tract E-Pneumonia is not associated with secondary bacterial infectionsarrow_forwardWhich of the following is NOT true about human plague (Yersinia pestis infection)? Which option is the answer? 1. None of the other four answers (All are true about human plague) 2. Infected fleas’ gastrointestinal tract is blocked by Y. pestis growth, causing them to regurgitate and infect a new host when they bite 3. Painful swollen lymph nodes are called “buboes” 4. Usually acquired in the US from bites of fleas that have fed on infected urban rats 5. Yersinia pestis infection of lymph nodes can sometimes spread to the lungs, causing secondary pneumonic plaguearrow_forward
