64. What is commonly used as a method of early detection to improve situational awareness, especially in the context of bioterrorism? A. Preventive surveillance B. Preventive syndrome C. Syndromic prevention D. Syndromic surveillance

93) Human intervention a. Like using antiviral to vaccinate individuals b. The dose of the vaccine can treat the disease c. Can increase the severity of the viral disease d. Like using antiviral to treat the viral disease

Which of the following is NOT true about Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) and the disease it causes? Which option is the answer: 1. During Coronavirus Disease (COVID-19), a person is the most highly infectious for others during the period of peak viral load and symptoms 2. As it is transmitted through the global human population, the virus is highly genetically stable and does not change 3. Some people who become infected with SARS-CoV-2 will not develop signs and/or symptoms of disease 4. The severity of disease varies greatly, depending on age and/or underlying predisposing conditions 5. Emerging SARS-CoV-2 variants may sometimes be more transmissible than previous strains

The epidemiological or disease triangle is a model of disease causation that proposes three factors contribute to an outbreak – an agent that causes the disease, a susceptible host, and an environment that brings the host and agent together. Some general changes within these three factors that may cause an infectious disease to emerge include:     A. changes in populations or behavior of reservoir hosts or intermediate hosts   B. microbial genetic mutation and viral genetic recombination or assortment    C. environmental factors such as an increase in precipitation   D. all of the above    E. none of the above

You are working in a pathology lab studying the virus Examinaria in mice. You collect the following information about two competing Examinaria strains, Aggressive and Mild: 1. Aggressive always out-competes Mild within a mouse for a payoff of 1. 2. Mild co-exists with Mild in a host for a payoff of 12. 3. Mild always loses to Aggressive for a payoff of 0. 4. Aggressive competing with Aggressive in a host leads to early death of the mouse and a payoff of only 14. Make a payoff matrix to solve this game. Based on the payoff matrix, is there one best Evolutionarily Stable Strategy (ESS) in this game? Yes, Aggressive is the ESS Yes, Mild is the ESS No, Mixed ESS

There are multiple epidemiologic study designs.  Study designs can be categorized as an experimental or observational design.  What is the primary difference between the two? (Choose the one best answer)      1. In an experimental design, the outcome/disease is assigned 2. In an observational design, the outcome/disease is assigned 3. In an experimental design, the exposure/treatment is assigned 4. In an observational design, the exposure/treatment is assigned 5. They are both epidemiologic study designs without a distinct difference

Discuss 2 notable case studies of specific health care institutions in the US that extensively utilize robots and AI. Please also include the sources where the information was obtained.

topic: Zika Virus write summary on a virus and its tropism for specific hosts, tissues, or cells. For example, you may want to discuss: the distribution/expression of the relevant cell surface receptor or other factors modulating viral entry, or you may want to focus on the environment in a specific niche that makes it conducive for infection by the virus. You can also choose to research a tangential topic like how tropism is considered in vaccine development. thank you-

Please answer both asap
