The dynamics of how a new virus transmits through human populations are not well understood. One theory is that it is being transmitted from human to human through exposure to mosquitoes at workplaces. If this proves to be true, installing mosquito nets at workplaces would provide employees with sufficient protection against the new virus. The scientific evidence does not yet indicate whether this hypothesis is correct. During an epidemic in a foreign country, a Canadian researcher working under the auspices of an institution eligible for Agency funding proposes a research protocol that aims to test this hypothesis. The methodology essentially consists of recruiting employees working for different employers, randomly assigning them to Group A (using mosquito nets) or Group B (control group not using mosquito nets), and assessing the relative effectiveness of mosquito nets by observing the incidence of the virus in these two groups. (please answer all questions by YES or NO).n order to facilitate the consent process, the researcher plans to exclude all employees who are minors and may need parental consent to participate. Based on the provided reason, would the exclusion of this group from the study be ethically acceptable?

Consider the situation where, in the course of the research, definitive scientific evidence becomes available that the virus can be transmitted from human to human, but not through mosquitos. Do you believe that the researcher should continue the study as initially approved by the REB?

t is known that roughly 5% of the general population carry a certain virus. A health researcher believes that among caucasian males the percentage is actually lower. Which of the following will provide the most convincing evidence to support the researcher’s suspicion? Out of 25 randomly chosen caucasian males, 1 male carries the virus. Out of 70 randomly chosen caucasian males, 3 males carry the virus. Out of 6,000 randomly chosen caucasian males, 288 males carry the virus. Out of 6,000 randomly chosen caucasian males, 240 males carry the virus.

An illness caused by a certain virus includes fever, rash, joint pain, red eyes, and headache. The virus is transmitted to people by infected mosquitoes. Symptoms quickly occur within three to twelve days after contracting the virus. There is no vaccine for this virus.Which description best explains the reproductive cycle of this virus?Ask Studybuddy (Login to use)Group of answer choicesLytic, because the virus is transmitted by mosquitoesLysogenic, because there is no way to vaccinate against itLytic, because of the quick incubation timeLysogenic, because the virus causes a fever
