Explanation / Answer

Elisa test done on two children on day 7 and day 12

Measles is self resolving infection within 10 to 12 days

Child 1 at day 7 igM production and igG production both present

Positive IgM and IgG tests for antibodies detected in an initial blood sample mean that it is likely that the person became infected with virus within recent weeks. ... If the IgG is positive but the IgM is low or negative, then it is likely that the person had an infection sometime in the past.

Child 2 has igM more than igG means he has active infection therefore both are infected but children 2 have active infection

Both igG IgM are produced in primary immune response

IgM peaks in 7 to 10 days and decrease rapidly and in 4 to 6 weeks become undetecteble

IgG production peaks in 4 weeks and persist lifelong giving lifelong immunity
