    Insights

    Most imported chikungunya cases in Taiwan were misdiagnosed as dengue, highlighting the need for better diagnostic tools. Active surveillance at entry points is crucial for controlling chikungunya and dengue outbreaks.

    Area of Science:

    • Arbovirology
    • Epidemiology
    • Public Health

    Background:

    • Chikungunya and dengue are mosquito-borne viral diseases with overlapping clinical symptoms.
    • Accurate diagnosis is essential for effective disease management and control.

    Observation:

    • A study in Taiwan identified 78 imported chikungunya cases between 2006 and 2014.
    • A significant majority (84.6%) of these chikungunya cases were initially suspected as dengue.

    Findings:

    • The high rate of misdiagnosis underscores the diagnostic challenge in differentiating chikungunya from dengue based on clinical presentation alone.
    • Laboratory diagnostics are indispensable for accurate identification of chikungunya virus infections.

    Implications:

    • Enhanced surveillance for febrile illnesses at points of entry is recommended to detect imported cases of chikungunya and dengue early.
    • Improved diagnostic strategies are needed to support public health interventions and prevent local transmission of chikungunya and dengue.

    Viral Mutations

    A mutation is a change in the sequence of bases of DNA or RNA in a genome. Some mutations occur during replication of the genome due to errors made by the polymerase enzymes that replicate DNA or RNA. Unlike DNA polymerase, RNA polymerase is prone to errors because it is not capable of “proofreading” its work. Viruses with RNA-based genomes, like HIV, therefore accrue mutations faster than viruses with DNA-based genomes. Because mutation and recombination provide the raw material...

    Viral Recombination

    Cells are sometimes infected by more than one virus at once. When two viruses disassemble to expose their genomes for replication in the same cell, similar regions of their genomes can pair together and exchange sequences in a process called recombination. Alternatively, viruses with segmented genomes can swap segments in a process called reassortment.

    Single Nucleotide Polymorphisms-SNPs

    A single nucleotide polymorphism or SNP is a single nucleotide variation at a specific genomic position in a large population. It is the most prevalent type of sequence variation found in the human genome. Point mutations that occur in more than 1% of the population qualify as SNPs. These are present once every 1000 nucleotides on an average in the human genome. Replacement of a purine with another purine (A/G) or a pyrimidine with another pyrimidine (C/T) is known as a transition. In contrast,...
