“…The high seroprevalence of CHIKV in our study could be related to the fact that we had high pre-outbreak seroprevalence (43·6%) and the main occupation of most women in the study area was rubber plantation worker, where natural and man-made holes in the trees, and the rain that collects in the cups used for collecting rubber latex, are good breeding areas for A. albopictus [24, 25]. In addition, our serosurveillance was performed 4 months after the peak of the CHIKV outbreak, so seroprevalence would be higher than seroprevalence during the outbreak, which is confirmed by a previous study that found during the epidemic upsurge and the post-epidemic era that CHIK seroprevalences were 18·2% and 38·2%, respectively [26].…”

Limited information is available on the seroprevalence of chikungunya virus (CHIKV) infection and maternal-fetal transmission incidence of CHIKV and dengue virus (DENV) infections during the 2008-2009 CHIKV outbreak in southern Thailand. A community-based post-epidemic seroprevalence study was conducted in parturient women admitted to the Thepa District Hospital in Songkhla Province, Thailand, for delivery from November 2009 to May 2010. The women were tested for chikungunya (CHIK) IgM/IgG and dengue (DEN) IgM/IgG. Cord blood samples were also tested for CHIK IgM or DEN IgM in women who tested positive for CHIK IgM or DEN IgM, respectively. The seroprevalence of CHIKV infection (CHIK IgM or IgG positive) was 227/319 (71·2%) with pre-outbreak seroprevalence (IgM-/IgG+) of 43·6% and the seroprevalence of DENV infection was 288/319 (90·3%). Complications during pregnancy, newborn outcomes and congenital anomalies were not different in those who had recent, remote or no CHIKV infections. None of the newborns whose mothers were CHIK or DEN IgM positive had cord blood positive for both CHIK and DEN IgM. In conclusion, both CHIKV and DENV are endemic in southern Thailand; during the recent CHIKV outbreak CHIK seroprevalence increased from 43·6% to 71·2%.

Climate change is expanding the global at-risk population for vector-borne diseases (VBDs). The World Health Organization (WHO) health emergency and disaster risk management (health-EDRM) framework emphasises the importance of primary prevention of biological hazards and its value in protecting against VBDs. The framework encourages stakeholder coordination and information sharing, though there is still a need to reinforce prevention and recovery within disaster management. This keyword-search based narrative literature review searched databases PubMed, Google Scholar, Embase and Medline between January 2000 and May 2020, and identified 134 publications. In total, 10 health-EDRM primary prevention measures are summarised at three levels (personal, environmental and household). Enabling factor, limiting factors, co-benefits and strength of evidence were identified. Current studies on primary prevention measures for VBDs focus on health risk-reduction, with minimal evaluation of actual disease reduction. Although prevention against mosquito-borne diseases, notably malaria, has been well-studied, research on other vectors and VBDs remains limited. Other gaps included the limited evidence pertaining to prevention in resource-poor settings and the efficacy of alternatives, discrepancies amongst agencies’ recommendations, and limited studies on the impact of technological advancements and habitat change on VBD prevalence. Health-EDRM primary prevention measures for VBDs require high-priority research to facilitate multifaceted, multi-sectoral, coordinated responses that will enable effective risk mitigation.

“…However, statistics on mosquito-borne diseases were not recorded. An Indian study in rubber plantations in Kerala revealed that 12 species of mosquitoes were found to breed in rainwater-filled cups used for collecting rubber latex [17]. Likewise, 69.2 % of the rubber farmers found snakes in their area.…”

This study aimed to investigate the working hazards and health problems among rubber farmers in the southern part of Thailand. A cross-sectional survey questionnaire was employed to identify the workers’ working hazards and health problems, workers’ postures, and the measurement of the intensity of light, lung function, and eye vision. Results indicated that 45.5 % of the rubber farmers were exposed to a chemical substance, 87 % were exposed to a scorpion, and 27.6 % had a high job strain. Furthermore, 43.8 % of the rubber farmers had a high ergonomic risk when collecting the rubber latex. However, the intensity of the headlamp had met the standard. Findings also revealed some common health problems among rubber farmers. These were musculoskeletal disorders (87.7 %), depression symptoms (15.7 %), and hand eczema (8.9 %). Additionally, nearly half of the Thai rubber farmers had an accident at work (45.1 %, while 22 % reported to have bitten by a poisonous animal. Lastly, 78.4 % of the rubber farmers had a low level of visual requirement and half of them had an abnormal lung function (57.2 %). These findings suggest a need for work process modifications to prevent health hazard in Thai rubber farmers.
