Concept explainers

Viral Infections

Viruses are abundantly found, minute entities that have genetic material enclosed within a protein coat. The proteinaceous material enclosing the genetic material of the virus is called a capsid. The genetic material could be either DNA (deoxyribonucleic acid) or RNA (ribonucleic acid). A virus is too minute to be looked at with naked eyes and therefore visualized with the help of a microscope. They are acellular entities that require a host for processes, such as replication, transcription, translation and multiplication. Plants, animals, and bacteria act as host wherein the virus reproduce. Viruses cannot multiply outside the host's body and thus are considered nonliving outside the host body.

Last year 68 year old Juana received her influenza vaccination and two days later she showed all the signs and symptoms of having contracted influenza. A year later she refused to receive another influenza vaccine because she believes she will get influenza from the vaccine. Explain to her (1) why her association with the vaccine and getting sick is incorrect and (2) why it is important for her to get the vaccine.
A mother calls the clinic to ask what medication to give her 5-year-old child for a fever during a bout of chickenpox. The nurse’s best response would be: a )“Your child is 5 years old, so it would be okay to use children’s aspirin to treat his fever.”b )“Start with acetaminophen or ibuprofen, but if these do not work, then you can try aspirin.”c )“You can use children’s dosages of acetaminophen or ibuprofen, but aspirin is not recommended.”d )“It is best to wait to let the fever break on its own without medication.”
Your grandmother, age 79, says her physician is recommending she get a flu shot. She states she has always been healthy and asks you why she needs this shot.
Let’s say there are two closely related viruses, let’s call them Guernsey virus and Micro virus. These two viruses only infect epithelial cells. Their surface antigens are sufficiently similar that there are a number of shared epitopes between the two viruses. Choose one of the following: A) If you get infected and successfully recover from one virus, it’s quite possible that you’ll have neutralizing antibodies against the other. B) If you get infected and successfully recover from one virus, you’ll still be susceptible to the other one because the antigens aren’t exactly the same. C) If you get infected and successfully recover from one virus, it’s likely that getting infected with the other virus will be worse because of the common phenomena of antibody-dependent enhancement. D) Not enough information has been given.
When the patient's mother expresses concern about his sister being reinfected with chickenpox, what is the most appropriate response? A) Your concerns are valid, but his sister developed an active natural immunity to chickenpox because she has already been infected. B) Your concerns are valid and there is a high likelihood that his sister will become infected again. We should probably administer the vaccine. C) Your concerns are valid and there is no way to protect his sister from becoming reinfected except to keep her at least 15 feet from your son at all times. D) Your concerns are valid and if his sister is reinfected, her symptoms will be less severe than her initial chickenpox infection.
Mr. Y’s HIV is being managed on a combination drug regimen that includes two nucleoside reverse transcriptase inhibitors (NRTIs) and one protease inhibitor (PI). His viral load is currently 50,000 copies/ mL; 3 months ago, his viral load was undetectable. His CD4+ T-lymphocyte count is 526 cells/mm3, down from 680 cells/mm3 3 months ago. Although he has been following his HAART regimen, he has experienced multiple complications, including several opportunistic infections. In light of his medical history, Mr. Y is especially concerned about his shortness of breath and hemoptysis. 1.What is the mechanism of action of the NRTI drugs that Mr. Y is taking for his HIV? 2. What is the rationale for the use of combined drug therapy in the treatment of HIV?
d) After your immune system subdues the virus, you wake up in sweaty clothes. i) Explain generally why you wake up in that state and ii) describe the steps that occur in your body that result in this response. e) Bats have been implicated as the source of many viruses against which humans have a difficult time mounting an effective immune response. Interestingly, flight plays an important role. i) Describe and explain i) the role that flight plays in creating these kinds of viruses, ii) how the viruses cross over into humans, and iii) why our immune response has a more difficult time mounting an effective response against them 4 Temperature
Which link in the chain of infection is the intervention described below meant to break?

Justine is a 14-year-old who is a star player on her high school's soccer team. The team is currently 17-2 this year and has a chance at going to the state championship. Over the past few days, Justine began feeling ill with noticeable signs of a high fever. Her parents decided to take her to the emergency room to get looked at. The attending physician admitted her to the hospital with an ongoing bacterial infection. It has been several days and the doctors are perplexed that her body is unable to fight off the infection. The doctors take a blood sample and have it sent to the lab for analysis. The lab results indicate that the vacuoles in her white blood cells are successfully trapping the bacteria. However, one specific organelle is malfunctioning; specifically, this organelle is not binding to the vacuoles and therefore cannot release the enzymes necessary to break down the bacterial cell walls. Identify the malfunctioning organelle so doctors can begin providing the proper…
