It is able to indicate which subtype of the virus infected the person; Serology test: finally, this is recommended from the sixth day of symptoms, this test checks the presence of antibodies against the virus in the body. A positive result for IgM indicates an active infection, while a positive IgG suggests a previous infection or convalescence.
