Flavivirus Infection

Flavivirus infections are caused by a group of single-stranded RNA viruses within the Flaviviridae family, primarily transmitted by mosquitoes and ticks, leading to significant global public health concerns. These infections include diseases such as Yellow Fever, Dengue, Japanese Encephalitis, and Zika virus infection, which can manifest as severe febrile illnesses, encephalitis, or hemorrhagic fever. Endemic in tropical and subtropical regions, particularly in Asia, the Americas, and parts of Africa, flaviviruses pose a major threat due to their potential for outbreaks and emerging variants. The immune response, especially humoral immunity, plays a critical role in protection against these infections. Notably, Zika virus is associated with congenital defects such as microcephaly, highlighting the broad clinical and epidemiological impact of this viral group.
