Background: Dengue virus (DENV), Zika virus (ZIKV), and chikungunya virus (CHIKV) continue to pose significant public health risks. This study aims to assess the prevalence of these arbovirus infections in field-caught mosquitoes across Asia.
Methods: Studies published after the year 2000 on DENV, ZIKV, and/or CHIKV infections in Asian mosquitoes were identified from Embase, Scopus, PubMed, and Ovid.
Article Synopsis
- Japanese encephalitis virus (JEV) is a common cause of encephalitis in Asia, transmitted to humans primarily through mosquito bites, with pigs and birds serving as main hosts.
- This study found JEV neutralizing antibodies in non-human primates (NHPs) and humans in Thailand, indicating natural infection and transmission between species, with seropositivity rates of 14.7% in monkeys and up to 45.2% in humans.
- The results suggest a need for ongoing serological studies at the animal-human interface to monitor JEV, especially given the higher infection rates in older humans.
From 2018 to 2020, the Chikungunya virus (CHIKV) outbreak re-emerged in Thailand with a record of more than 10,000 cases up until the end of 2020. Here, we studied acute CHIKV-infected patients who had presented to the Bangkok Hospital for Tropical Diseases from 2019 to 2020 by assessing the relationship between viral load, clinical features, and serological profile. The results from our study showed that viral load was significantly high in patients with fever, headache, and arthritis.
