Mapping malaria in Thailand: A Bayesian spatio-temporal analysis of national surveillance data.

Objectives: Malaria, caused by protozoan parasites of the genus Plasmodium, remains prevalent in tropical and subtropical regions. This study employed Bayesian spatio-temporal analysis to assess malaria incidence patterns and identify environmental and climatic correlates across Thailand at the district level.

Methods: We analysed national malaria surveillance data using Bayesian hierarchical models to examine spatio-temporal patterns in malaria incidence.

Gastrointestinal Helminthic Infection among the Population in Northern Thailand.

Purpose: Gastrointestinal (GI) helminthic infections pose substantial public health threat, particularly in northern Thailand, with a heightened concern in Nan province. This study aims to evaluate the prevalence of GI helminthic infections in Nan province and identify associated risk factors in local population.

Methods: A cross-sectional survey was conducted in 2022.

Formalin-fixed stool improves the performance of the Kato-Katz method.

Background And Aim: Parasitic infections are a public health problem worldwide, including in Thailand. An epidemiological survey for helminthiasis based on stool examination uses the Kato-Katz method as recommended by the World Health Organization. Limitations of this method include the need for fresh stool, time requirement, and lack of quality control.

Reduction of carcinogens in fermented fish (pla-ra and pla-som) by heating.

Background And Aim: The risk factors for cholangiocarcinoma (CCA) are opisthorchiasis and the intake of a combination of nitroso compounds through the consumption of traditionally fermented fish, which is very popular in areas where liver flukes are endemic. The incidence of CCA remains high because this cultural habit of rural people has been altered. Therefore, decreasing nitrate and nitrite concentrations in fermented fish are an alternative approach to reducing the risk of CCA.

Current status of helminthiases in Thailand: A cross-sectional, nationwide survey, 2019.

Helminthiases are common neglected tropical diseases in Thailand, thus regular surveillance is necessary for their control. During fiscal year 2019, the Thailand Ministry of Public Health carried out a cross-sectional nationwide survey in people of all age groups from the 12 Regional Health Offices in 76 provinces of Thailand. Multi-stage cluster random sampling design was employed to assess the prevalence of helminth infections and certain behavioural risk factors.
