Question

Raju’s friend, Kamal got infected with chicken pox. He was afraid to go near him, but
his father told him that he won’t get infected with chicken pox again. Raju was surprised
to know this

Answer 1

Because once if we get chicken pox while being 1 or two years old, you won’t be affected again. But it is also normal to not get chicken pox in this period too. If this happens, you have a chance to get it later. So this is what happened to Kamal. But it seems that Raju already had chicken pox when he was 1 or 2 years old. So it is not going to happen to him again.
