- The lack of evidence-based data is one of the reasons for the apparent lack of a unified global strategy in handling the present COVID 19 pandemics. Hussain (2020), echoed a proposed pathophysiology of SARS-CoV2 binding to ACE2 with high affinity as a virus receptor to infect humans through spike glycoproteins on the surface of its membrane. Armed with this premise, create a concept map of SARS-CoV2 pneumonia. Start by describing the viral impact on the cells of the respiratory system. Justify GIT manifestations and why the hypertensive elderly patient is particularly considered at greater risk for mortality.Fig. 13.6 shows that closely related lentiviruses have closely related hostorganisms. What does this observation suggest about the ability of lentiviruses to infect a wide variety of hosts?Compare Ebola Virus to SARS-CoV2 with respect to the following parameters: 1. Capsid morphology, genome 2. Host portal of entry 3. Viral receptor binding protein and host cell receptor
- The emerge of the SARS-COV-2 and middle east respiratory syndrome (MERS)-COV illustrate the threat of cross species transmission leading to out breaks in humans. What is the history of transmission of SARS-COV-2 to humans? What animals were involved in the transmission? Could this transmission happen again with other viruses?X is a zoonotic infection first identified in humans in 1970 in the Democratic Republic of Congo. The infection presents clinically with fever, rash and swollen lymph nodes and may lead to a range of medical complications. X was first identified outside of Africa in 2003 and later reported in the United States of America, linked to contact with infected pet prairie dogs. The pets were reportedly housed with Gambian pouched rats and dormice, imported from Ghana. X has also been further reported in travelers from Nigeria to different countries around the world between 2018 and 2021. This resulted in multiple cases of X identified in several non-endemic countries in 2022, including South Africa. 3.1 Explain the clinical symptoms and laboratory diagnosis of infection X( five each)X is a zoonotic infection first identified in humans in 1970 in the Democratic Republic of Congo.

- Discuss the role of each of these factors in the causation of the COVID-19 pandemic. Be specific with respect to the molecular mechanisms responsible for these effects: 1. zoonotic virus origins 2. immunologically naive population 3. SARS-CoV-2 virulence factors affecting transmissibility 4. evolution of immune-resistant virus variants.The SIR model of pandemics (such as COVID-19) considers three variables: S (those susceptible to the disease) I (those infected with the disease), and R (those recovered or removed from the illness). This model has a system of three differential equations, one for the derivative of each variable. We viewed the video entitled "The Coronavirus Curve - Numberphile," and we also rebuilt this model in Geogebra ourselves. That model includes two constants, "transm" and "recov:" use Ct instead of "transm," and use cr instead of "recov." In Geogebra, we could tweak these values. a. In this system, what is the equation for S'(t) = dS/dt? b. In this system, what is the equation for I'(t) = dI/dt? c. In this system, what is the equation for R'(t) = dR/dt? d. Who made this video?Use GEO2R to perform pairwise group analysis of Rabies Virus. Explore and identify the most regulated genes: gene/protein functions of Rabies virus and Define the significance of these genes/proteins in the disease process.
- Discuss how the SARS-CoV-2 virus causes Covid-19 disease became a "new" zoonotic disease and has resulted in a "fast" spreading World-Wide Pandemic. how has it evolute as a zoonotic disease, the mechanism of infection in humans, symptoms of disease, treatment and prevention. Describe how to "flatten" the curve and make the epidemic a "slow" epidemic by acting as a "social" vaccine.← → Review E Bookmark x BIOLOGY (2010) / SECTION 1 / 2 OF 60 Which source would provide the most in-depth information for investigating adenoviruses? OA. A popular magazine having a drawing and photograph of an adenovirus OB. A local newspaper citing methods of protection from adenovirus infection OC. A scientific dictionary defining the word adenovirus OD. A microbiology journal describing the structure and function of an adenovirusSince early 2020 human societies around the world have suffered a viral pandemic and struggled to cope with Covid-19. Provide one example of a policy or response that has been effective and one example of a policy or response that has been ineffective. Propose a policy that should be implemented in the near future.
