Influenza, herpes, covid, hiv, ebola Choose one pathogen, briefly and mechanistically explain how its latency works. How is latency helpful to this pathogen? What challenges does it overcome through its latency?

What was the important use of telemedicine during Covid 19 pandemic period?

Describe the pathogen that causes “The Flu”. What happens you get the flu and how did you most likely acquire it. Explain how the causal pathogen is different from many other pathogens in terms of why it can cause epidemics and pandemics and why you need an annual vaccine. Define the terms antigenic shift and antigenic drift and explain how they are related to this disease.

A few years ago researchers identified another protein involved in cell invasion by P. falciparum, Rh5.  PfRh5 is required in red blood cell invasion.  It binds to a specific protein (basigin) in red blood cell membranes and it shows almost no variation among P. falciparum strains.  What part(s) of this story is/are important relative to our discussion on malaria vaccines?  Option C: PfRh1 appears to be invariant All three of these observations (A-C) are crucial Option A: PfRh1 is required for cell invasion, i.e. no alternative pathways Option B: PfRh1 binds to basigin Options A and C

During the 2015 Ebola outbreak in West Africa, Ebola aid workers like Abdul Lebbie engaged in a practice called contact tracing. These contact tracers locate and isolate (through quarantine) individuals who may have come into contact with an infected individual. Contact tracing is an attempt to reduce the RO of a disease by: reducing the infectious period reducing the transmission rate reducing the virulence increasing the infectious period O increasing the transmission rate

Please compare and contrast the Severe Acute Respiratory Syndrome (SARS), the Middle East Respiratory Syndrome (MERS), and Coronavirus (COVID-19) pandemic death numbers hitherto. Are the deaths comparable? If yes or no, why?

Explain why a different influenza vaccine is necessary every year. How is this different from the development of pandemic versions? Please include in your answer the terms antigenic shift and antigenic drift.
