zalisa [80]

The period of Convalescence is the time during which the person regains health and fully recovers.

Explanation:

  • Diseases that can spread from one person to other  are called infectious disease.
  • Disease development is divided into Incubation period, Prodromal period, period of illness, Decline period, and period of Convalescence.
  • During incubation period the pathogen enters the host body and starts multiplying itself. But the signs of diseases are unnoticeable.
  • Then comes  the prodromal period, when the pathogen keeps multiplying itself and some signs of disease are observed but they are not obvious
  • After the prodromal period comes the period of illness when the patient exhibits obvious signs of sickness.
  • As the period of illness is over the symptoms of disease start to cease and the the number of pathogen decrease in body.This period is the period of decline.
  • Finally comes the period of Convalescence when the person returns to his pre-disease state and is completely healthy. (except irreversible damage caused by the disease)

An unknown white powder is tested by an antibody based detection system. The test does not indicate the presence of anthrax, yet
Volgvan

Answer: The correct answer is option C.

Explanation:

A false negative test is a diagnostic error in which a test shows absence of a disease even when a person is having a disease.

Similarly, in the given question a sample has anthrax spores; however, antibody test fails to show the presence of anthrax. Thus, it is a false negative.

In contrast, false positive error is the error in which the test shows the presence of disease even when a person is not suffering from it.

Sampling error is a statistical error.

Thus, the correct answer is option C.
