- 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. RhinovirusThere have been recurring cases of mad-cow disease in the United Kingdom since the mid-1990s. Mad-cow disease is caused by a prion, an infectious particle that consists only of protein. In 1986, the media began reporting that cows all over England were dying from a mysterious disease. Initially, there was little interest in determining whether humans could be affected. For 10 years, the British government maintained that this unusual disease could not be transmitted to humans. However, in March 1996, the government did an about-face and announced that bovine spongiform encephalopathy (BSE), commonly known as mad-cow disease, can be transmitted to humans, where it is known as variant Creutzfeldt-Jakob disease (vCJD). As in cows, this disease eats away at the nervous system, destroying the brain and essentially turning it into a spongelike structure filled with holes. Victims experience dementia; confusion; loss of speech, sight, and hearing; convulsions; coma; and finally death. Prion diseases are always fatal, and there is no treatment. Precautionary measures taken in Britain to prevent this disease in humans may have begun too late. Many of the victims contracted it over a decade earlier, when the BSE epidemic began, and the incubation period is long (vCJD has an incubation period of 10 to 40 years). A recent study concluded that 1 in 2,000 people in Great Britain carry the abnormally folded protein that causes vCJD. In spite of these numbers, the death rate from vCJD remains low. It is not clear whether this means that the incubation period for the disease is much longer than previously thought, or whether they may never develop the disease.

- Although the virus that causes smallpox has been eradicated, there are still stocks of the virus, which are kept in labs in the US and Russia. Why may someone argue that these stocks be destroyed?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.Viruses are considered non-living microbes, and yet they are responsible for many major disease outbreaks in humans, animals, and even plants.

- Which of the following characteristics, structures,or processes is common to both bacteria andviruses?(A) metabolism(B) ribosomes(C) genetic material composed of nucleic acid(D) cell divisionWhich of the following statements concerning viruses and human health is false? a-in many diseases caused by viruses, the virus attacks cells as it reproduces b- many viral diseases can be controlled through vaccinations c- some viruses can remain dormant in the body for years before disease symptoms appear d-most viral infections are difficult to treat, but they can be finally destroyed by antibioticsWill it be possible to eradicate many viral diseases in the same way as smallpox? Why or why not?
- According to your own understanding, what do you think makes viruses some of the most common disease causing organisms? Explain comprehensivelyThe first virus studied that led to the term "filterable virus" was rabies?Hana comes from an island town of 2000 people. She goes to the mainland with a friend and there they catch a highly contagious virus. A week after their return to their island-town, 8 people are infected. How many will be affected after another week? If there are 150 bacteria after 2 hours and 900 bacteria after 6 hours, how many bacteria were present initially? How many bacteria are there after 10 hours?
