A patient is feeling the onset of the flu, by feeling fatigue . 2. There was a of bubonic plague back in the 14th century. 3. This is a disease that have isolated infections in a particular population. 4. The patient came in with manifestations of rabies. This is described as what type of disease. . 5. You are working with a patient who has influenza, you must wear a mask if working within 3 feet due to droplet precautions. This is an example of what type of disease . 6. These are routinely detected in a population or region. . 7. If you do not wipe correctly after a bowel movement, this may introduce E. coli into the urogenital tract. This is an example of . 8.

2.3 Infectious Cycles and Disease Transmission Please read the short passage and fill in the blanks with the appropriate words that explain how epidemiologists describe diseases in a population. Drag word(s) below to fill in the blank(s) in the passage. Epidemiologists study the movement of diseases in a population. They describe [blank] diseases that are constantly in a(n) [blank]. These diseases are generally seen at a [blank] rate. When several cases appear over a short time, a(n) [blank] is declared; if it spreads and affects people throughout the [blank], it is called a(n) [blank]. etiologic individual community endemic vector zoonotic world epidemic high low pandemic

Influenza A virus is the most pathogenic of the human influenza viruses. Its envelope encloses a protein complex (vRNP) and eight, single-stranded, negative RNA (the complement of a positive RNA strand that can be transcribed by a ribosome) segments (vRNA). Each segment encodes one or two proteins that support viral replication. On the outer surface of the envelope are proteins that recognize and bind to host receptors. A. Annotate the representation below to briefly describe each process associated with a numbered label. B. Describe influenza A viral replication as a process regulated by either positive or negative feedback and justify your selection. The human-acquired immunodeficiency syndrome (AIDS) and many cancers are cause by double-stranded RNA retroviruses C. Contrast the processes of viral replication of HIV and influenza A virus. D. Explain the difference in the effects of infection by HIV and influenza A virus on host genetic variability. E. Measured mutation rates for influenza A virus and HIV are nearly identical (Sanjuan et al., Jour. Virology, 2010). Explain this observation even though host error-checking operates in one of these replication modes
Identity and discuss a bacterial disease that caused a historically important plague or epidemic. What is the modern distribution of this disease? a. Bubonic plague caused by Yersinia pestis was a pandemic that occurred in the 14th century. In modern times, there are only about 100 cases of bubonic plague each year. The bacterium responds well to modern antibiotics. b. Bubonic plague caused by Yersinia enterocolitica was a pandemic that occurred in the 14 th century. In modern times, there are about $1,000$ to $3,000$ cases of bubonic plague each year. The bacterium responic plague modern antibiotics. c. Pneumonic plague caused by Yersinia pestis was a pandemic that occurred in the 14 th century. In modern times, there are about $1,000$ to $3,000$ cases of pneumonic plague each year. The bacterium responds well to modern antibiotics. d. Bubonic plague caused by Yersinia pestis was a pandemic that occurred in the 14th century. In modern times, there are about $1,000$ to $3,000$ cases of bubonic plague each year. The bacterium responds well to modern antibiotics.
