Chapter 1, Problem 1SEPT

The physical sensations of a disease that can only be relayed by a patient such as nausea and pain are called O 1) signs O 2) syndrome O 3) symptoms O 4) etiology

Drugs are often given to patients before going into surgery, to dentalpatients with heart disease, or to healthy family members exposed tocontagious infections.a. What word would you use to describe this use of drugs?b. What is the purpose of this form of treatment?c. Explain some potential undesired effects of this form of therapy.d. Define probiotics and list some ways they are used.

which of the following choices lists the periods of disease development in the correct order? a. incubation -illness-decline-concalescence-prodromal b. prodromal-incubation-illness-decline-convalescence c. incubation-prodromal-illness-decline-convalescence e. incubation-illness-decline-prodromal-convalescence

a. During which stages of an infectious disease does the host exhibit signs and symptoms? Is there a correlation between this and when a disease is communicable? b. Why are some viral diseases, like smallpox and polio, no longer seen in the United States? Why are many bacterial disease, like syphilis, no longer a death sentence? Think about how these two types of microbes infect humans. Why might we make an effort to treat viral diseases before infection but continue to treat bacterial diseases after infection? c. Based on the graph below, which pathogen is more virulent: Agent 1 or Agent 2? Explain. 100 Agent 1 LD5 = 400, Agent 2 LD50 = 600 25 100 200 300 400 500 600 700 800 900 1,000 Dose (organisms administered per animal) Percent mortality 75

The study of the causes of diseases is known as etiology. ___________ ____________ ___________ __________

Foodborne pathogens often require the presence of a large number of microbes before an active infection results. These microbes would have a high A.) median infectious dose (ID50). B.) incubation period. C.) virulence. D.) median lethal dose (LD50). E.) mortality.

Describe the four general mechanisms by which microorganisms cause disease.

Which of the following is false about disease burden? a.The burden of disease globally has shifted increasingly toward noncommunicable diseases b.The years of life lost due to diabetes has been increasing c.The years of life lost due to premature death of children has been decreasing d. The burden of disease globally has shifted increasingly toward communicable diseases

Describe the different ways a disease can be transmitted? What impact do we have as human that can support the control of transmission? What tactics, skills and/or techniques will you implement going forward to help control the transmission of microbes in your daily life?
