Answer:
Chickenpox is highly contagious viral infection with red rash over entire body as its most prominent feature. It is widely spread throughout the world and is usually more severe in adults, especially in pregnancy, then in children. Persons with chickenpox should avoid contact with other people in order to avoid spreading of the infection, which is the reason why the doctor suggested Sachin to stay at home. Although his friend persuaded him to go to the picnic, Sachin refused, thus reflecting values of listening and respecting authority concerning health issues and acting responsibly in order to prevent infection spreading.
