Sohan was a very active and a social child. He used to come forward for anybody help. One day he attended a blood donation camp and was ready to donate blood, but his blood test was done and he was HIV+ve. Therefore he was very upset and lost his interest in all activities and remained absent from school for long time. Rajiv, his friend met him and counselled him. He (Sohan) was back at school. a) What sense of responsibility did Rajiv show? b) A HIV+ve person should be isolated. Do you agree with this statement. Justify your answer?

Explanation:

(a) After vis friends comforted him he went back to school.

(b) No. HIV can only be caught by another person of they come in contact with your blood or through sexual intercourse. So it is not possible for others to become infected if they didn't come in contact with the person's blood or have unprotected intercourse. There is no reason for a HIV+ve person to isolate themself from the outside world. They are people just as we are but they only have something that can cause them to be really sick.
