A 5 year old boy has been having fever for 2 days. Dengue IgM and IgG were requested and revealed: IgM = negative
IgG = positive
Question: What will be your advice to the parents?
Notably, dengue fever is normally a viral infection an individual can suffer from due to weather changes, especially when one travels from one place to another. The virus is transmitted by mosquitoes that live in tropical and subtropical areas.
In this regard, a laboratory antibody blood test of IgM and IgG is taken to test the virus.
IgM antibodies are well detected after 7 to 10 days of exposure.
In the above question, IgG is positive and IgM is negative. In this regard, it means that the person had an infection sometimes back like Chikungunya.
