BACKGROUND: Infectious disease is an important health problem in border areas as there is a possibility that the migrants may carry the disease into the area. The purpose of this study is to evaluate the knowledge and behaviors toward human papillomavirus (HPV) and cervical cancer in the women of reproductive age in the Thailand-Myanmar border area.
METHODS: A survey study in a population of 418 women of reproductive age in Mae Hong Son Province in the Thailand-Myanmar border area. Knowledge and risk behaviors of HPV and cervical cancer were described using descriptive statistics.
RESULTS: Fifty percent of the participants had sexual debut at age less than 20 years, 27% had more than one lifetime sexual partner and only 3% had sex outside a monogamous relationship during the past 12 months. In term of knowledge, 62.5% knew about HPV. The proportion of correct answers about HPV and cervical cancer questions ranged from 14-95% and 52-94%, respectively. Among the cervical cancer screening target, 69.4% accessed the screening. The factors associated with better knowledge about HPV and cervical cancer were education level higher than high school and sexual debut.
CONCLUSIONS: The women of reproductive age in the Thailand-Myanmar border areas showed relatively low sexually risk behaviors for HPV infection. More than one-third of the participants did not know about HPV. The percentage of correct answer to questions about cervical cancer were low.  We encourage the Thai Ministry of Public Health to increase health promotion and health literacy on prevention of HPV and cervical cancer in the women of pre- and reproductive age in the Thailand-Myanmar border area.

BACKGROUND: Fever is a common reason to seek healthcare in Southeast Asia, and the decline of malaria has complexified how is perceived, and what actions are taken towards it. We investigated the concept of fever and the determinants influencing health-seeking behaviours among migrants on the Thai-Myanmar border, where rapid economic development collides with precarious political and socio-economic conditions.
METHODS: We implemented a mixed-methods study between August to December 2019. Phase I used a qualitative approach, with in-depth interviews and focus group discussions. Phase II used a quantitative approach with a close-ended questionnaire based on Phase I findings. A conditional inference tree (CIT) model first identified geographic and socio-demographic determinants, which were then tested using a logistic regression model.
RESULTS: Fever corresponded to a high diversity of conceptions, symptoms and believed causes. Self-medication was the commonest behaviour at fever onset. If fever persisted, migrants primarily sought care in humanitarian cost-free clinics (45.5%, 92/202), followed by private clinics (43.1%, 87/202), health posts (36.1%, 73/202), public hospitals (33.7%, 68/202) and primary care units (30, 14.9%). The qualitative analysis identified distance and legal status as key barriers for accessing health care. The quantitative analysis further investigated determinants influencing health-seeking behaviour: living near a town where a cost-free clinic operated was inversely associated with seeking care at health posts (adjusted odds ratio [aOR], 0.40, 95% confidence interval [95% CI] [0.19-0.86]), and public hospital attendance (aOR 0.31, 95% CI [0.14-0.67]). Living further away from the nearest town was associated with health posts attendance (aOR 1.05, 95% CI [1.00-1.10] per 1 km). Having legal status was inversely associated with cost-free clinics attendance (aOR 0.27, 95% CI [0.10-0.71]), and positively associated with private clinic and public hospital attendance (aOR 2.56, 95% CI [1.00-6.54] and 5.15, 95% CI [1.80-14.71], respectively).
CONCLUSIONS: Fever conception and believed causes are context-specific and should be investigated prior to any intervention. Distance to care and legal status were key determinants influencing health-seeking behaviour. Current economic upheavals are accelerating the unregulated flow of undocumented migrants from Myanmar to Thailand, warranting further inclusiveness and investments in the public health system.

In this paper, we describe the development of the film, \"Under the Mask,\" which follows the lives of three fictional characters who live on the Thai-Myanmar border as they journey from diagnosis of tuberculosis (TB) to completion of treatment. Under the Mask was filmed on location on the Thai-Myanmar border by local filmmakers and former refugee populations. Cast members were chosen from communities living along the border. This paper describes the script development process, filming, and screening in the community. We also report the findings from the pre- and post-screening questionnaires and post-film focus group discussions. A total of 77 screening events took place between March 2019 and March 2020 to 9,510 audience members in community venues such as village squares, temples and monasteries (N = 21), schools/migrant learning centers (N = 49), and clinics (N = 4). The pre-and post-screen questionnaires showed a significant gain in self-perceived TB knowledge on prevention, transmission, signs and symptoms, and related discrimination. Our findings from 18 post-screening focus group discussions conducted with 188 participants showed that there were improvements in knowledge and awareness of the disease and treatment, as well as in the awareness of stigma, and the burdens of tuberculosis on patients and their families.

This study aimed to assess the health outcome of four epidemic-prone infectious diseases, in the context of a Primary Health Care project implemented in a protracted refugee setting along the Thai-Myanmar border.
Refugees settled at the Thai-Myanmar border are fully dependent on support for health services, shelter, food, education, water, and sanitation. The Non-Governmental Organization Malteser International developed an integrated Primary Health Care program in close cooperation with trained camp residents over 25 years in the two settlements under its supervision. The project has been funded by the European Commission Civil Protection and Humanitarian Aid Operations (DG ECHO).
This was a retrospective primary health care project evaluation. All-cause mortality; morbidity trends in malaria, lower respiratory tract infections (LRTIs), watery diarrhea, and dysentery; and health service utilization covering a time span of 18 years were assessed. Programmatic changes in the Primary Health Care (PHC) project and events with a potential effect on health of the target population were examined.
Despite the continuous drain of trained health care workers, the volatile influx of refugees, and the isolated location of the two camps, the initial basic curative health care developed into an integrated and comprehensive PHC project including a SPHERE-compliant water, sanitation, and hygiene program. Malaria, LRTIs, watery diarrhea, and dysentery morbidity dropped twelve, three, two, and fivefold, respectively, over the 18-year period evaluated while the health services utilization dropped from 7.1 to 2.9 consultations per refugee/year. The international community may face situations where integration of refugees into the health services of the host country is not possible. In such a context, integrated and evidence-based PHC adequately funded and implemented by one health agency is an effective and relevant approach to reduce the infectious diseases burden under the constraints of semipermanent living conditions.

Background&objectives: Changes in parasite biology, particularly the gametocytogenesis process, could be one of the important contributing factors for worldwide malaria resurgence. The present study investigated the prevalence rates of pretreatment gametocyte carriage and density in Plasmodium falciparum and P. vivax infections in the low malaria-endemic area on the Thai-Myanmar border.
METHODS: One hundred and twenty-six blood samples were collected from patients with signs and symptoms of malaria who attended malaria clinics. Malaria positive cases detected by microscopic examination were confirmed by species-specific nested-PCR in 97 (29 and 68 samples for P. falciparum and P. vivax, respectively).
RESULTS: The proportion of P. vivax and P. falciparum-infected samples was 70.1: 29.9%. The density in P. falciparum positive samples [median (95%CI): 10,340 (5280-19,200) μ/l] was significantly higher than P. vivax positive samples [4508 (3240-6120) μ/l]. Sixteen out of twenty-nine (55.2%) and 36 out of 68 (52.9%) P. falciparum- and P. vivax-infected samples, respectively, were gametocyte-positive. Gametocyte density in the P. falciparum-infected[124 (69-253) /μl] was significantly higher than that of the P. vivax-infected [54 (45-70)/μl] samples. A significant correlation between gametocyte density and pretreatment parasitemia was only detected in P. falciparum-infected, but not P. vivax-infected samples.
CONCLUSIONS: The observed high prevalence rates of pretreatment gametocyte carriage of both malaria species, which serves as a large malaria reservoir, particularly in P. falciparum infection, could have a significant impact on malaria control in the endemic populations.

Rising nativism and political volatility worldwide threaten to undermine hard-won achievements in human rights and public health. Risks are particularly acute for hundreds of millions of migrants, minorities, and Indigenous peoples, who face disproportionately high health burdens, including HIV/AIDS, and precarious legal status (LS). While LS is receiving increasing attention as a social determinant of health and HIV, understandings are still limited to select immigrant communities. Its effects on health among stateless communities, particularly in the Global South, remain largely unknown. Moreover, widespread limitations in census measures of LS reduce its complexity to a simplistic citizen/non-citizen binary or insufficient proxies. Thailand\'s ethnolinguistically diverse highlander population experiences disproportionately high HIV prevalence and comprises one of the world\'s largest and most protracted cases of statelessness, an acute condition of precarious LS. As such, analysis of LS and health outcomes among highlanders is both critically warranted, and useful as a case study outside of the migration paradigm.
Drawing on the UNESCO Highland Peoples Survey II (2010), an unprecedented and unique cross-sectional census of highlanders in Thailand, we mobilize complex measures of LS in adjusted ordinal logistic regression models to assess how parent citizenship and LS adjudication over the early life course condition adult HIV knowledge-a key protective factor against transmission (n = 8079).
Adjusted ordinal logistic regression on knowledge scores reveal that parent citizenship predicts odds of greater knowledge by 1.4- to 2.2-fold, depending on ethnic group. This is partially explained by divergent stages of LS adjudication between birth and adulthood, including successful birth registration and adult citizenship acquisition, along with secondary school completion. Precisely how these factors contribute to HIV knowledge varies by ethnic group.
This study advances knowledge of LS outside of the migration paradigm, reveals heretofore unexamined connections between LS and access to public health information, and elucidates how instabilities in LS adjudication stages underlie health inequalities over the life course. Findings indicate that securing success in public health and human rights agendas requires attention to how states adjudicate and deploy LS in multiple stages across the life course to structure access and exclusion among migrant and non-migrant communities alike.

Following the coup in Myanmar, humanitarian assistance, including coronavirus disease 2019 (COVID-19) control, must be implemented on the Thai-Myanmar border in the framework of international cooperation. The actual number of refugees was expected to increase in the Karen state at the end of March 2021, and they are at risk of contracting COVID-19 as they live in overcrowded conditions without access to basic sanitation. The global community has been hesitant to provide direct support because of fearing that such support would benefit the military. To reach this most vulnerable population, further strengthening of support through the Thai-Myanmar border as an alternative channel that was used before Myanmar\'s democratic transition in 2011 is necessary.

Chronic conflict and displacement carry consequences for personal and social violence. How is violence embedded in displacement-related histories and ongoing circumstances? How might it underlie social and health inequities in host countries? For addressing these questions, I offer a new approach to conceptualizing and measuring displacement contexts and the structural violence embedded therein. I present the empirical case of the Thai-Myanmar border. Myanmar\'s civil conflict has fueled one of the largest and most chronically displaced populations globally. Thailand\'s border population has consequently grown with people displaced from the varied conflict-related circumstances within Myanmar. I administered a novel survey in two sub-districts along Thailand\'s northern border with Myanmar in 2016-17. With data from 520 respondents, I used clustering of life events and circumstances to uncover displacement-related contexts and violence. I uncovered livelihood- and security-based threat contexts, which disproportionately affected ethnic minority women. Among women from Myanmar, past military occupation and acute violence co-occurred with unexpectedly low perceived past oppression-indicative of covert everyday violence. In contrast, women who fled home destruction or deprivation, but often less overt military violence, were more likely to perceive oppression. Women born in Myanmar also experienced acute potential violence at the border, including severe livelihood and security threats. These threats were most prevalent among women that experienced the most forceful and abrupt displacement. This study uses a person-centered perspective to characterize and measure violence embedded in displacement, including the structural violence against women that is perpetuated across displacement contexts and embodied over time.

BACKGROUND: In low malaria transmission areas, many people acquire multiple malaria infections within a single season. This study aimed to describe the pattern and epidemiological profile of malaria recurrence in a hypoendemic area of western Thailand and identify factors associated with having multiple malaria episodes.
METHODS: An open cohort of 7000 residents in seven clusters along the Thai-Myanmar border was followed during a 6.5-year period (2011-mid 2017). Symptomatic and asymptomatic malaria infections were detected by passive case detection (PCD), weekly household visit, and mass blood surveys every 4-6 months. Malaria recurrence was defined as subsequent parasitaemic episodes occurred later than 7 days after receiving anti-malarial treatment. This study focused on analysis of recurrent episodes that occurred within 1 year after treatment. Numbers of malaria cases with single and multiple episodes were compared between clusters. Kaplan-Meier curve was performed to determine the intervals of recurrent episodes by Plasmodium species and age groups. The ordinal logistic model was used to determine factors associated with multiple malaria episodes, and to compare with single episodes, and those with no malaria infection.
RESULTS: The cumulative incidence of malaria in the study area was 5.2% over the 6.5 years. Overall, 410 malaria patients were detected. Of these patients, 20% and 16% had multiple malaria episodes during the entire period and within 1 year after initial treatment, respectively. About 80% of repeated malaria episodes were caused by the same Plasmodium species as the primary infections. The median interval and interquartile range (IQR) between the first and second episode was 88 (43-175) days for all parasites, 56 (35-133) days for two Plasmodium falciparum episodes, and 90 (59-204) days for two Plasmodium vivax episodes. The interval between the episodes was increased with age. Factors significantly associated with multiple episodes of malaria infection included male sex, young age, Karen ethnicity, forest-related occupation, and having other malaria infected persons in the same house in the same period.
CONCLUSIONS: People who have multiple malaria episodes may play an important role in maintaining malaria transmission in the area. Understanding epidemiological profiles of this group is important for planning strategies to achieve the elimination goal.

Blastocystis sp. is a common zoonotic intestinal protozoa which has been classified into 17 subtypes (STs). A cross-sectional study was conducted to determine the prevalence and subtype distribution of Blastocystis in villagers living on the Thai-Myanmar border, where the risk of parasitic infection is high. A total of 207 stool samples were collected and DNA was extracted. PCR and sequencing using primers targeting small-subunit ribosomal RNA (SSU rRNA) gene were performed. The prevalence of Blastocystis infection was 37.2% (77/207). ST3 (19.8%; 41/207) was the predominant subtype, followed by ST1 (11.6%; 24/207), ST2 (5.3%; 11/207), and ST4 (0.5%; 1/207). A phylogenetic tree was reconstructed using the maximum likelihood (ML) method based on the Hasegawa-Kishino-Yano + G + I model. The percentage of bootstrapped trees in which the associated taxa clustered together was relatively high. Some sequences of Blastocystis positive samples (TK18, 39, 46, 71, and 90) were closely related to animals (pig and cattle) indicating zoonotic risks. Therefore, proper health education in parasitic prevention for the villagers should be promoted to improve their personal hygiene. Further longitudinal studies are required to monitor the prevalence of parasitic infections after providing health education and to investigate Blastocystis ST in animals living in these villages.
