Diagnostic chikungunya by realtime rt-pcr
WebJun 13, 2024 · The first marker detected in CHIK infection is the viral RNA, usually by reverse transcription-polymerase chain reaction (RT-PCR). This marker can be identified in samples within 8 days of symptom onset. The infection can also be diagnosed with serological testing to detect CHIKV-specific immunoglobulin IgG and/or IgM. WebChikungunya virus (CHIK) is a small positive sense RNA virus with a genome of almost 11800 nucleotides from the genus Alphavirus and family Togaviridae. Chikungunya virus is most often spread to people by Aedes aegypti and Aedes albopictus mosquitoes which can also spread Dengue viruses. The virus can, in some occasions, be transmitted ...
