Nondetection of infectious hepatitis B virus in a human hepatoma cell line producing hepatitis B surface antigen.

abstract：:Dengue and chikungunya fevers are transmitted by the common mosquito vector Aedes and malaria by Anopheles. Concurrent infections are reported due to co-circulation of these pathogens, especially in endemic regions. We report a rare case of triple infection with 3 arthropod-borne pathogens (Plasmodium vivax and the de...
