- 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?A fake country of Wathu has been giving a virus treatment tablet for free to poor citizens who exhibit symptoms. The tablet makes somewhat sick people feel a bit better and reduces the death rate of those who are extremely sick. Nobody sells counterfeit pills and no prescriptions are needed for the tablets. Some of the poor Wathu citizens are selling their treatment tablet to richer citizens for $400, which is what the rich citizens would have to pay to the treatment center per tablet. The marginal cost of production is $400. How would prohibiting these voluntary transfers of treatment tablets affect total surplus?1. TRUE OR FALSE:There is strong evidence that the "seeds" for life in this planet might have come from outer space, since evidence for complex organic molecules (e.g. amino acids) has been discovered in meteorites and in outer space. 2. TRUE OR FALSE: Kuru is caused by a neurotropic virus that "homes" or looks for the brain cells. This virus belongs to the same family of viruses that cause mad cow disease, and it is one of the smallest "life forms" in planet earth. 3. TRUE OR FALSE: Over 150 complex organic molecules have been identified in deep space; some of these resemble amino acids. The study suggest that all three environments; outer [deep] space, meteorites and the surface of a planet may all very well lent a hand in the development of life. 4. TRUE OR FALSE: One of the limitations of the current fossil record in our planet is that it is biased in favor of the species that have left hard bony structures and/or had lived for long periods of time. 5. TRUE OR FALSE: To date, we…
- How do emerging viruses arise? by the spread of existing viruses to new host species by mutation of existing viruses by the spread of existing viruses more widely within their host species all of the aboveThe coronavirus pandemic of 2020 is an example of a novel virus appearing in the global human population. A novel virus is a new virus: one that has been neither identified nor studied before.Just last week the Energy Department now seems pretty confident that the coronavirus came from a lab leak: https://www.nytimes.com/2023/02/26/us/politics/china-lab-leak-coronavirus-pandemic.html The textbook discusses how the environment is part of the epidemiologic triangle. What is the epidemiologic triangle? (Figure 10-2, p.210). Why does it matter where this coronavirus started? Do you have any theories about how the virus was transmitted to humans?
- 1. Ebola virus, a dangerous outbreak was found to have occurred due to possible transmission of virus from bats and the contact of contaminated bodily fluids such as blood, urine, etc. Therefore, such a devastating disease outbreak around the world which initially broke in West Africa that along with acute poverty went through lack of proper healthcare, transportation, communication and resources, made it difficult for public health in bringing a quicker solution against it, hence spreading faster. I think to prevent similar pandemics in the future, countries especially with low economies should be prepared with potential resources to combat a health emergency. Moreover, international countries should intervene by investing in African healthcare systems, especially in places suffering from extreme poverty, to build stronger and accessible health care that provides treatment for its residents (Matua et al., 2015). Local Public health officials should visit certain vulnerable places and…An elementary school student comes down with a stomach virus the day after she swims at the local pool. Her father warns other parents at the school that the pool is unsanitary and causes virus to spread. What should the parents conclude? Choose the best answer. The pool is indeed unsanitary and causes viruses to spread. The pool is not unsanitary and does not cause viruses to spread. There is an association between people visiting the pool and increased reports of viruses. There is no association between people visiting the pool and increased reports of viruses. Nothing can be concluded because this is an anecdote.discuss methods used to control vector-borne diseases, specifically mosquitos. 1) Is there one method you think is more beneficial than others when it comes to the controlling and prevention of mosquito-borne diseases? Why/why not? 2) Also, how large do you think is the impact of human environmental change (man's activities) on emerging infectious diseases in animals and man?
- Select all the statements that are true regarding the drug treatments available for infectious diseases.□ Antiviral drugs are harder to develop than antibiotics because viruses must use our cellular machinery replicate. □ Very few anti-parasitic drugs exist because diseases caused by Eukaryotes are extremely rare all over the world.□ Fewer drugs are available to treat Eukaryotic pathogens because their physiology and functions are very similar to our own.□ Development of antiparasitic drugs are a low priority because the diseases they treat tend to occur in poor countries, and drug companies can't make money.□ Antivirals may quit working because rates of viral mutation are very high.□ There are more antiviral drugs than atibiotics because antiviral drugs are very easy and cheap to make.Viruses are considered non-living microbes, and yet they are responsible for many major disease outbreaks in humans, animals, and even plants. Consider the following: How are these non-living microbes able to reproduce without metabolic functions? Can viruses be exploited to help humans fight bacterial pathogens? Which viruses are able to stay dormant in the human body and reactivate later in life or when immune defenses are compromised? What impact might travel outside of the United States have in blood, tissue, or organ donation? Please answer question 1, 2, 3, and 4 if possible, thank you.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? We already have effective vaccines for Herpes. Influenza and CoV have more genes, more complex gene expression, and can undergo genetic recombination or reassortment, while Herpesviruses are more limited. Only humans get Herpesviruses, while animals can get Influenza viruses and Coronaviruses. 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.
