Article Synopsis
- Chikungunya fever is a viral disease transmitted by mosquitoes and was reported in a small outbreak in Tanjung Sepat, Malaysia in 2019, prompting a study to explore factors influencing its transmission.
- A cross-sectional study involving 149 healthy participants was conducted to analyze blood samples for CHIKV antibodies and identify risk factors associated with positive results.
- Results showed that a significant 72.5% of participants were seropositive, with household contact to infected individuals being a key factor; the study suggests increased community testing and mosquito repellents to control future outbreaks.
Article Synopsis
- Getah virus (GETV) is a newly recognized animal pathogen spread by mosquitoes, with four identified groups, but only Group III (GIII) is linked to disease outbreaks.
- The study analyzed genetic and phenotypic differences between epidemic GIII strains and non-epidemic strains, revealing unique amino acid changes in critical viral proteins associated with GIII and GIV.
- Results showed that GIII strains replicated more efficiently in both mammalian and mosquito cells, indicating that higher replication rates may contribute to their virulence and epidemic potential.
A new Getah virus (GETV) strain, B254, was isolated from Culex fuscocephalus mosquitoes captured at Mount Ophir, Malaysia, in 2012. Phylogenetic analyses revealed that GETV B254 is distinct from the old Malaysia GETV MM2021 strain but closely related to group IV GETV from Russia (LEIV16275Mag), China (YN12031), and Thailand (GETV/SW/Thailand/2017).
