Why do scientists worry more about new strains of viruses like influenza and coronviruses as potential causes of deadly human pandemics, but they never talk about the next big Herpesvirus strain deadly pandemic? Which of the statements below helps partially answer that? O We already have effective vaccines for Herpes. O Influenza and CoV have more genes, more complex gene expression, and can undergo genetic recombination or reassortment, while Herpesviruses are more limited. O Only humans get Herpesviruses, while animals can get Influenza viruses and Coronaviruses. O dsDNA viruses aren't very transmissible and even when they are, they're not deadly. Influenza and CoV are RNA viruses which results in having higher mutation rates -- they can more easily jump between host species. Herpesviruses are dsDNA viruses and usually very host specific.

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"?

Some older vaccines used a weakened strain of the pathogenic virus in the injection in the hope that the weakened virus would induce an immune response without causing disease. The virus vectors used in genetic engineering have all the harmful virus genes cut out and replaced with the foreign gene, such as one that makes a protein that is absent in the human patient. Which type of viral vaccine would you prefer to take as the safest option? Why? Some Covid 19 vaccines in development use the adenovirus, a common vector used in gene therapies, to inject the mRNa for the spike protein into human muscle cells. Why might vaccines using a virus vector be more likely to need only refrigeration and not deep-cold storage, given what you know about viruses?
Coronaviridae is a virus “family.” There are actually many different coronaviruses within this group, including less pathogenic virus strains that cause the common cold. Many people in this course have likely been infected with one of these other coronaviruses. A common feature of coronaviruses and other RNA viruses (think influenza virus, HIV, etc.) is that they mutate frequently. This is because the viral enzymes that copy the genome during replication can’t fix mistakes. Given this information, how might we be able to distinguish the SARS-CoV-2 strain from some of the other, less concerning, coronavirus strains?
The novel Coronavirus (COVID-19) is a virus for which no known vaccine is available yet. A person diagnosed with the virus can only be managed with the hope that their immune system will fight the virus. Governments of many countries (including Ghana) are now beginning to accept the reality that until a vaccine is found, ways must be adopted to be able to live with the virus without contracting it. This means that same must be done at the workplace as well. A single person found to have contracted the virus will have a lot of implication on the organisation. This certainly is a source of concern for HR managers in the organisation. i. Explain four (4) of the HR implications should the workforce contract this virus. ii. Apart from the various safety protocols outlined by the W.H.O. and health sectors of various countries, discuss how four (4) of the various HR practices could be employed to help fight this pandemic.
Describe the lysogenic cycle of a virus. What is the difference between the lytic and lysogenic cycle of a virus? What are vaccines? Define the words “Emerging Virus” and “Pandemic”. Give examples of human diseases caused by viruses. What is a prion and viron? Are prion and virons viruses? Give examples of human or animal diseases caused by prions and what organisms are affected.

Which of the following highly contagious viruses is a single-stranded ribonucleic acid (RNA) virus with a helical capsid and envelope and is transmitted by coming in contact with respiratory secretions? "This is a highly contagious respiratory illness transmitted when an infected person coughs or sneezes virus particles into the air," the health department said in a written statement. "It's so contagious that if one person is sick and spreading measles, nine out of 10 people around them who aren't immune will get it, too." Group of answer choices a. Measles b. Parvovirus c. Coxsackie virus A d. Rhinovirus
The National Institutes of Health (NIH) set up a study to determine whether large doses of vitamin C would shorten the length of time it takes to recover from a cold. Three thousand volunteers were split into two groups. For two weeks, members of Group A took 3,000 mg of vitamin C daily. Group B received 3,000 mg of a placebo. At the end of the two-week period, the researchers inserted live cold viruses directly into the noses of all the volunteers. The volunteers in both Group A and B continued to take their daily pills. All the volunteers got colds, and there was no significant difference in the length of time the colds lasted. What is the experimental group in this example? Select the best answer. Group B. Three thousand volunteers. Group A. The live cold virus. Length of time the colds lasted. The vitamin C. Size of pill (3000 mg).
How common is ABV in the USA? In the United States, over half of adults have been infected with ABV by age 40. Once ABV is in a person's body, it stays there for life and can reactivate. Match terms with descriptions based on the text above. You can use an answer more than once or not at all. "Over half of adults have been infected with ABV by age 40." ABV could belong to this group of viruses: A. Human Papilloma Viruses B. Incidence of ABV C. Herpesviruses D. Prevalence of ABV by age 40
You have a discussion among friends about viruses that can cause latent and chronic infections in humans. The first friend says that an example for latent infections in humans are oral and genital herpes caused by herpes simplex virus and that examples of viruses causing chronic infections are Hepatitis C and HIV. The second friend says oral and genital herpes as well as chickenpox/ shingles are chronic infections and that HIV is an example for a virus causing a latent infection. O The first person is correct O The second person is correct
This article highlights a young doctor at Elmhurst Hospital during the beginning of Covid-19 pandemic. Dr. Zikry is quoted as saying: “It’s become very clear to me what a socioeconomic disease this is...”. In addition, the textbook discusses the personal variables and socioeconomic status (SES) that are used to find patterns in disease (pp.112-118). What do you think Dr. Zikry meant by referring to the SES of his patients? Why was it important to find a pattern of personal variables and SES among the of victims of Covid-19 at the beginning of the pandemic?
An outbreak of Ebola between 2014 and 2016 resulted in 28,616 cases and 11,310 deaths in Guinea, Liberia and Sierra Leone. An additional 36 cases and 15 deaths were reported outside these 3 countries. This deadly disease urged the need for extensive research on Ebola to better understand and treat the disease and prevent future outbreaks. Ebola is a - SSRNA virus. What does this mean for how it is converted into proteins? Does this virus require additional machinery to be infectious? Can you hypothesize based on how it replicates in the cell what scientists might hope to target for treatment or prevention of Ebola?
