Answer 1

because once if anyone had suffered from chicken pox then they never get it again as a chemical antigen or resistance is produced in our body so that it will never come again . if anyone has not given proper vaccine or does not got chicken pox atleast once then they has a chance to get pox.so we should be having care to visit person having pox. if once chicken pox came,passive resistance is produced in ones body which will make body not to suffer from it again
