Question

Which of the following statements about the development of infectious diseases is correct?

Answer 1

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)
