What do positive results in a dengue test mean?

Positive results in a Dengue ELISA test indicate the presence of dengue-specific antibodies or antigens in the blood. A positive IgM result suggests a recent dengue infection, as IgM antibodies are typically produced within a few days to a week after infection. A positive IgG result indicates a past infection or a secondary infection, as IgG antibodies appear later and can persist for years. In the case of a positive NS1 antigen test, it indicates an active dengue infection, particularly in the early stages before antibodies have developed. Positive results require immediate medical attention for further evaluation and management. Treatment usually involves supportive care, such as fluid replacement, pain relief, and monitoring for complications. In some cases, hospitalisation may be necessary for severe symptoms. It is also important to notify public health authorities to help control the spread of the virus.
