- Ebola was a new plague of the 20th century that had a high mortality rate. What is Ebola, what are its origins and how did it manage to spread to Europe and America, especially New York?
Step by step
Solved in 3 steps
- The Ebola epidemic spread to ten countries, but it never officially became what is known as a pandemic. What are the differences between the two terms?Why do you think there are no longer polio cases in the US, but there are some cases of influenza?Why is the Ebola virus considered a serious/dangerous virus?
- Considering 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?How much time does it take for a flu pandemic to infect people all around the world?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 problems
- What is the Coronavirus? Is it a living organism? How does it reproduce? The current vaccines that are being distributed in the United States are made by Pfizer, Moderna, and Johnson and Johnson. Explain how they work and how health officials believe they will aid in the pandemic? What should we expect as more and more people get vaccinated? Will things immediately go back to the way they were before? What is the Delta variant and how is it impeding on getting things back to "normal"?Why is it that Many children still die each year from malaria, but we don't seem to hear the same outcry as the one we had when Zika became widespread? Is malaria being treated seriously like Zika was?In Europe, for several centuries, measles has been a childhood infection that rarely kills. When European settlers came to the New World, however, the measles virus they brought with them killed a large portion of native populations. Explain.
