Can fungal infection cause a false herpes 2?

Yes, certain fungal infections can potentially lead to false-positive results for herpes simplex virus type 2 (HSV-2) in some diagnostic tests. This is primarily due to cross-reactivity in serological tests, where the immune response to a fungal infection may mistakenly trigger a positive result for HSV-2 antibodies. However, such instances are relatively rare, and confirmatory testing is often recommended to ensure accurate diagnosis. Always consult a healthcare professional for proper testing and interpretation of results.
