Southeast Asia is a region with great potential for the emergence of a pandemic influenza virus. Global efforts to improve influenza surveillance in this region have documented the burden and seasonality of influenza viruses and have informed influenza prevention strategies, but little information exists about influenza vaccination guidelines and vaccine sales.

Strategy for the control of foot-and-mouth disease in Southeast Asia (SEAFMD)

Edwards JR

Dev Biol (Basel), 2004;119:423-31.
PMID: 15742655

The OIE Southeast Asia Foot-and-Mouth Disease Campaign (SEAFMD) involves the coordinated control of foot-and-mouth disease by eight of the ASEAN countries. A long term vision for SEAFMD has been developed and the core element is a progressive zoning approach to the control and eradication of FMD in the region. This paper describes the current status of FMD in Southeast Asia and progress towards achievement of OIE free zone status for FMD in parts of the Philippines and Malaysia and the initiation of the Malaysia-Thailand-Myanmar (MTM) Peninsular Campaign for FMD Freedom. In mainland Southeast Asia, the progressive zoning approach involves several sub-regional groups working in parallel to oversee the epidemiological and economic studies required to determine the feasibility of the approach. Areas involved include the Lower Mekong Basin, Upper Mekong Basin, parts of Myanmar and the Red River Delta of Vietnam. The paper describes the current usage of vaccines for FMD in Southeast Asia and provides recommendations for their supply and use in the new regional initiatives.

Human immunodeficiency virus (HIV)-1 epidemics in Asian countries are driven by varying exposures. The epidemiology of the regional pandemic has been changing with the spread of HIV-1 to lower-risk populations through sexual transmission. Common HIV-1 genotypes include subtype B and circulating recombinant form (CRF) 01_AE. Our objective was to use HIV-1 genotypic data to better quantify local epidemics. TASER-M is a multicenter prospective cohort of HIV-infected patients. Associations between HIV exposure, patient sex, country of sample origin and HIV-1 genotype were evaluated by multivariate logistic regression. Phylogenetic methods were used on genotypic data to investigate transmission relationships. A total of 1086 patients from Thailand, Hong Kong, Malaysia and the Philippines were included in analyses. Proportions of male patients within countries varied (Thailand: 55.6%, Hong Kong: 86.1%, Malaysia: 81.4%, Philippines: 93.8%; p

PMID: 27244964

The aim of this study was to assess overweight or obesity and associated factors in school-going adolescents in the Association of Southeast Asian Nations (ASEAN) member countries. The analysis included 30,284 school children 13-15 years of age from seven ASEAN members participating in the Global School-based Student Health Survey (GSHS) between 2007 and 2013. The overall prevalence of overweight or obesity across seven ASEAN countries (excluding Brunei) was 9.9%, significantly higher in boys (11.5%) than in girls (8.3%). Among eight ASEAN countries, the highest prevalence of overweight or obesity was in Brunei Darus-salam (36.1%), followed by Malaysia (23.7%), and the lowest was in Myanmar (3.4%) and Cambodia (3.7%). Multivariate logistic regression analysis found that younger age, coming from an upper middle country, never been hungry, and not walking or biking to school were associated with overweight or obesity. In addition, among boys, having three or more servings of vegetables per day and having no close friends, and among girls, having fast foods two or more times per week, been victims of bullying and having peer support were additional factors associated with overweight or obesity. Increased strategies utilizing a number of the risk factors identified are needed to prevent and treat overweight or obesity in adolescents in ASEAN member countries.

Fulltext Confronting the HIV, Tuberculosis, Addiction, and Incarceration Syndemic in Southeast Asia: Lessons Learned from Malaysia

Culbert GJ, Pillai V, Bick J, Al-Darraji HA, Wickersham JA, Wegman MP, et al.

J Neuroimmune Pharmacol, 2016 09;11(3):446-55.
PMID: 27216260 DOI: 10.1007/s11481-016-9676-7

Throughout Southeast Asia, repressive drug laws have resulted in high rates of imprisonment in people who inject drugs (PWID) and people living with HIV (PLH), greatly magnifying the harm associated with HIV, tuberculosis, and addiction. We review findings from Malaysia's largest prison to describe the negative synergistic effects of HIV, tuberculosis, addiction, and incarceration that contribute to a 'perfect storm' of events challenging public and personal health and offer insights into innovative strategies to control these converging epidemics. The majority of PLH who are imprisoned in Malaysia are opioid dependent PWID. Although promoted by official policy, evidence-based addiction treatment is largely unavailable, contributing to rapid relapse and/or overdose after release. Similarly, HIV treatment in prisons and compulsory drug treatment centers is sometimes inadequate or absent. The prevalence of active tuberculosis is high, particularly in PLH, and over 80 % of prisoners and prison personnel are latently infected. Mandatory HIV testing and subsequent segregation of HIV-infected prisoners increases the likelihood of tuberculosis acquisition and progression to active disease, amplifying the reservoir of infection for other prisoners. We discuss strategies to control these intersecting epidemics including screening linked to standardized treatment protocols for all three conditions, and effective transitional programs for released prisoners. For example, recently introduced evidence-based interventions in prisons like antiretroviral therapy (ART) to treat HIV, isoniazid preventive therapy to treat latent tuberculosis infection, and methadone maintenance to treat opioid dependence, have markedly improved clinical care and reduced morbidity and mortality. Since introduction of these interventions in September 2012, all-cause and HIV-related mortality have decreased by 50.0 % and 75.7 %, respectively. We discuss the further deployment of these interventions in Malaysian prisons.

Pharmacovigilance activities in ASEAN countries

Suwankesawong W, Dhippayom T, Tan-Koi WC, Kongkaew C

Pharmacoepidemiol Drug Saf, 2016 09;25(9):1061-9.
PMID: 27174034 DOI: 10.1002/pds.4023

PURPOSE: This study aimed to explore the current landscape and identify challenges of pharmacovigilance (PV) among Association of Southeast Asian Nations (ASEAN) countries.
METHODS: This cross-sectional survey collected data from May 2014 to December 2015. Questionnaires seeking to collect information on resources, processes, roles and responsibility, and functions of PV systems were sent to relevant persons in the ASEAN countries. Functions of PV centers were measured using the minimum World Health Organization requirements for a functional national PV system. Performances of PV centers were measured by the following: (1) the indicators related to the average number of individual case safety reports (ICSR); (2) presence of signal detection activities and subsequent action; and (3) contribution to the global vigilance database.
RESULTS: Cambodia, Indonesia, Laos, Malaysia, the Philippines, Singapore, Thailand, and Vietnam completed the survey. PV systems in four surveyed countries (Indonesia, Malaysia, Singapore, and Thailand) achieved all aspects of the World Health Organization minimum requirement for a functional national PV system; the remaining countries were deemed to have unclear communication strategies and/or no official advisory committee. Average numbers of recent ICSR national returns ranged from 7 to 3817 reports/year/million population; three countries (Malaysia, Singapore, and Thailand) demonstrated good performance in reporting system and reported signal detection activities and subsequent actions. All participating countries had submitted ICSRs to the Uppsala Monitoring Center during the survey period (2013-2015).
CONCLUSIONS: Four participating countries had functional PV systems. PV capacity, functionality, and legislative framework varied depending on local healthcare ecosystem networks. Implementing effective communication strategies and/or technical assistance from the advisory committee are needed to strengthen PV in ASEAN. Copyright © 2016 John Wiley & Sons, Ltd.

PMID: 25962112 DOI: 10.1371/journal.pone.0126764

The majority of hepatitis C virus (HCV) infection results in chronic infection, which can lead to liver cirrhosis and hepatocellular carcinoma. Global burden of hepatitis C virus (HCV) is estimated at 150 million individuals, or 3% of the world's population. The distribution of the seven major genotypes of HCV varies with geographical regions. Since Asia has a high incidence of HCV, we assessed the distribution of HCV genotypes in Thailand and Southeast Asia. From 588 HCV-positive samples obtained throughout Thailand, we characterized the HCV 5' untranslated region, Core, and NS5B regions by nested PCR. Nucleotide sequences obtained from both the Core and NS5B of these isolates were subjected to phylogenetic analysis, and genotypes were assigned using published reference genotypes. Results were compared to the epidemiological data of HCV genotypes identified within Southeast Asian. Among the HCV subtypes characterized in the Thai samples, subtype 3a was the most predominant (36.4%), followed by 1a (19.9%), 1b (12.6%), 3b (9.7%) and 2a (0.5%). While genotype 1 was prevalent throughout Thailand (27-36%), genotype 3 was more common in the south. Genotype 6 (20.9%) constituted subtype 6f (7.8%), 6n (7.7%), 6i (3.4%), 6j and 6m (0.7% each), 6c (0.3%), 6v and 6xa (0.2% each) and its prevalence was significantly lower in southern Thailand compared to the north and northeast (p = 0.027 and p = 0.030, respectively). Within Southeast Asia, high prevalence of genotype 6 occurred in northern countries such as Myanmar, Laos, and Vietnam, while genotype 3 was prevalent in Thailand and Malaysia. Island nations of Singapore, Indonesia and Philippines demonstrated prevalence of genotype 1. This study further provides regional HCV genotype information that may be useful in fostering sound public health policy and tracking future patterns of HCV spread.

Fulltext Neglected tropical diseases among the Association of Southeast Asian Nations (ASEAN): overview and update

Hotez PJ, Bottazzi ME, Strych U, Chang LY, Lim YA, Goodenow MM, et al.

PLoS Negl Trop Dis, 2015 Apr;9(4):e0003575.
PMID: 25880767 DOI: 10.1371/journal.pntd.0003575

The ten member states of the Association of Southeast Asian Nations (ASEAN) constitute an economic powerhouse, yet these countries also harbor a mostly hidden burden of poverty and neglected tropical diseases (NTDs). Almost 200 million people live in extreme poverty in ASEAN countries, mostly in the low or lower middle-income countries of Indonesia, the Philippines, Myanmar, Viet Nam, and Cambodia, and many of them are affected by at least one NTD. However, NTDs are prevalent even among upper middle-income ASEAN countries such as Malaysia and Thailand, especially among the indigenous populations. The three major intestinal helminth infections are the most common NTDs; each helminthiasis is associated with approximately 100 million infections in the region. In addition, more than 10 million people suffer from either liver or intestinal fluke infections, as well as schistosomiasis and lymphatic filariasis (LF). Intestinal protozoan infections are widespread, while leishmaniasis has emerged in Thailand, and zoonotic malaria (Plasmodium knowlesi infection) causes severe morbidity in Malaysia. Melioidosis has emerged as an important bacterial NTD, as have selected rickettsial infections, and leptospirosis. Leprosy, yaws, and trachoma are still endemic in focal areas. Almost 70 million cases of dengue fever occur annually in ASEAN countries, such that this arboviral infection is now one of the most common and economically important NTDs in the region. A number of other arboviral and zoonotic viral infections have also emerged, including Japanese encephalitis; tick-borne viral infections; Nipah virus, a zoonosis present in fruit bats; and enterovirus 71 infection. There are urgent needs to expand surveillance activities in ASEAN countries, as well as to ensure mass drug administration is provided to populations at risk for intestinal helminth and fluke infections, LF, trachoma, and yaws. An ASEAN Network for Drugs, Diagnostics, Vaccines, and Traditional Medicines Innovation provides a policy framework for the development of new control and elimination tools. Together with prominent research institutions and universities, the World Health Organization (WHO), and its regional offices, these organizations could implement important public health improvements through NTD control and elimination in the coming decade.

Hepatitis A shifting epidemiology in South-East Asia and China

Barzaga BN

Vaccine, 2000 Feb 18;18 Suppl 1:S61-4.
PMID: 10683551

A review of the epidemiology of hepatitis A virus (HAV) infection over the last 20 years shows shifting patterns in the prevalence of antibodies to HAV (anti-HAV) throughout South-East Asia and China. A number of countries have shifted from high to moderate and from moderate to low endemicity, with a corresponding increase in the age of exposure from childhood to early adulthood. The changes have resulted from improvements in hygiene, sanitation and the quality of drinking water, reflecting improvements in living standards and socioeconomic progress. In general in the late 1970s and early 1980s, 85-95% of the population of developing countries like the Philippines, Korea, China and Thailand were anti-HAV-positive by age 10-15 years, compared with only about 50% in the more affluent countries like Malaysia and Singapore. In the early 1990s, 85-95% of the population were immune by age 30-40 years in the Philippines, Korea, China and Thailand, and by 50 years of age and above in Malaysia and Singapore. Similar trends were noted in Hong Kong, Taiwan and Japan. Exposure to HAV at a later age may be associated with an increase in hepatitis A morbidity and a greater propensity for outbreaks.

Taxonomy of Trichinella and the epidemiology of infection in the Southeast Asia and Australian regions

Pozio E

Southeast Asian J. Trop. Med. Public Health, 2001;32 Suppl 2:129-32.
PMID: 12041576

Seven species belonging to the Trichinella genus (five with encapsulated larvae and two with non-encapsulated larvae in host muscles) and three additional genotypes have been described to date: T. spiralis (genotype T1), a cosmopolitan species with a high infectivity to swine and rats; T. nativa (T2), etiological agent of sylvatic trichinellosis in arctic and subarctic areas of the Holarctic region, and its related genotype (Trichinella T6), detected in Alaska, Idaho, Montana, Pennsylvania, Wyoming, and Ontario; T. britovi (T3), etiological agent of sylvatic trichinellosis in temperate areas of Europe and Asia, and its related genotypes Trichinella T9 in Japan and Trichinella T8 in South Africa and Namibia; T. murrelli (T5), etiological agent of sylvatic trichinellosis in temperate areas of the USA; T. nelsoni (T7), etiological agent of sylvatic trichinellosis in Africa south of the Sahara; T. pseudospiralis (T4), a non-encapsulated cosmopolitan species infecting both mammals and birds; and T. papuae (T10), a recently discovered non-encapsulated species in sylvatic swine of Papua New Guinea. In the Southeast Asia and Australian regions, T. spiralis, T. pseudospiralis and T. papuae have been detected in sylvatic and domestic animals and in humans. A focus of human trichinellosis due to T. papuae was recently discovered in Papua New Guinea, with a prevalence of 28.9%. Trichinellosis has also been documented in domestic animals and/or humans in Cambodia, Indonesia (Bali and Sumatra), Lao PDR, Malaysia, Myanmar, Thailand, and New Zealand, and in wildlife of Tasmania.

PMID: 11852832

I assess the population health effects in Malaysia of air pollution from a widespread series of fires that occurred in Indonesia between April and November of 1997. I describe how the fires occurred and why the associated air pollution was so widespread and long lasting. The main objective is to uncover any mortality effects and to assess how large and important they were. I also investigate whether the mortality effects were persistent or whether they represented a short-term, mortality-harvesting effect. The results show that the smoke haze from the fires had a deleterious effect on the health of the population in Malaysia.

WHO's Declaration of the "Health for All" (HFA) goal was pronounced in 1978 in Alma Ata, and it was planned that HFA would be achieved through primary health care programmes and approaches by 2000. However, it is now 2002 and despite the technological advancements in medicine, science, and ICT, Health for All is far from reality. Instead, more and more conflicts are emerging with lethal consequences, such as, bioterrorism, biological agent abuse, global-terrorism, and environmental destruction is occurring at a greater scale that we have witnessed before. We may have the latest technology and knowledge today, but ironically, we are using them to inflict more suffering and pain in the world. In the Asia-Pacific, the past 30 years has seen dramatic advancement and lifestyle changes. We are now paying a high price for such progress in terms of risk factors to the health of the population, such as, ageing diseases, obesity, smoking, diabetes, hypertension, and related conditions. The social, political, economic and environmental factors appeared to have deterred and negated WHO's HFA goal to attain basic human rights and health care for all. The HFA will not be achieved in the future if we do not learn from history and start taking measures now.

Viruses belonging to the family Paramyxoviridae generally have not been recognized as a significant cause of disease in pigs until recently. Between 1997 and 1999, there were large outbreaks of disease in pigs in Australia and Malaysia due to infection with viruses that have been shown to be new members of the Paramyxoviridae family. This article reviews current knowledge of Menangle and Nipah virus infections in pigs, the only major species of domestic animals to experience serious disease after infection with these viruses.

Fulltext Hepatitis A virus: declining seroprevalence in children and adolescents in Southeast Asia

Kunasol P, Cooksley G, Chan VF, Isahak I, John J, Loleka S, et al.

PMID: 9886108

The prevalence of hepatitis A virus (HAV) in a country largely reflects its standards of hygiene and socioeconomic conditions. Countries which undergo socioeconomic development show major change in HAV prevalence from high to low endemicity, and this is largely reflected in patterns of age-related seroprevalence. This paper presents age-related HAV seroprevalence patterns of SE Asian countries, and highlights how these patterns have changed over recent decades. Singapore, Thailand and Malaysia have experienced a decline in childhood and adolescent HAV seroprevalence, typical of countries which undergo socioeconomic development. By contrast, India has remained a country of high endemicity, with almost universal seroconversion in childhood. The Philippines and Vietnam show age-related seroprevalence patterns typical of high to moderate endemicity, while Indonesia shows significant regional variation in HAV seroprevalence. Populations within countries which exhibit major improvements in endemicity and age related HAV seroprevalence patterns are at risk of HAV epidemics, and a paradoxical increase in incidence tends to occur as seroconversion shifts from children to adults. The residents of these countries, a significant number of whom are at-risk, would benefit from a program of vaccination, as would non-infected individuals visiting high-risk areas.

The lack of relationship between acetylator phenotype and idiopathic systemic lupus erythematosus in a South-east Asian population: a study of Indians, Malays and Malaysian Chinese

Ong ML, Mant TG, Veerapen K, Fitzgerald D, Wang F, Manivasagar M, et al.

Br J Rheumatol, 1990 Dec;29(6):462-4.
PMID: 2257457

An association of idiopathic systemic lupus erythematosus (ISLE) with genetically determined N-acetylation polymorphism has been suspected from previous studies, mainly on Caucasian populations in which there is an approximate incidence of 50% of slow and rapid acetylators. The present study is of the incidence of ISLE and acetylator status in a mixed population of Malaysia. The results did not support an association between ISLE and acetylator status: the frequencies of slow acetylators in the ISLE patients who were Malaysian Chinese and Malay were 13 and 38% respectively. This did not differ significantly from the respective healthy groups (20 and 29%). The small number of Indians in the survey did not allow a valid comparison, but the figures did suggest a lack of association between ISLE and acetylator status.

Current food and nutrition situation in south Asian and south-east Asian countries

Gopalan C

Biomed Environ Sci, 1996 Sep;9(2-3):102-16.
PMID: 8886320

Food production in the countries of South and South-East Asia has shown a general upward trend during the last decade. Despite the considerable increase in population in many of these countries, food production per capita in 1988-90 was significantly higher as compared to 1979-81 figures, the increase being specially marked in such countries as Vietnam, Cambodia, Indonesia, and Malaysia. Available daily calorie supply was adequate to meet the requirement. The overall pattern of food production however has shown little change, with cereal production continuing to account for a predominant part of food production. There is no evidence of a significant uptrend with respect to production of pulses, milk, horticultural products, poultry or meat production in most countries. A unique and unfortunate feature of the nutrition situation in South-Asian countries is that the incidence of low birth weight deliveries is as high as 34% (1990), ranging from 25% in Sri Lanka to 50% in Bangladesh (as against less than 7% in the countries of Europe and North America). Even in countries of Africa where the overall food and nutrition situation is worse than in South Asia, the incidence is well below 20%. This is a reflection of the poor state of maternal nutrition in pregnancy. Florid nutritional deficiency diseases have shown a steep decline over the last two decades, but goitre and iron deficiency anaemia continue to be major public health problems, though some headway has been made with regard to the control of the former. Severe forms of growth retardation in children have declined but the majority suffer from mild and moderate forms of growth retardation. Countries of the Region are in varying stages of developmental transition. Among the burgeoning middle classes in some of these countries there are evidences of escalation of degenerative diseases such as diabetes and coronary heart disease. With increasing life expectancy, geriatric nutritional problems will demand increasing attention.

Fulltext Cholera in selected countries in Asia

Lopez AL, Dutta S, Qadri F, Sovann L, Pandey BD, Bin Hamzah WM, et al.

Vaccine, 2020 02 29;38 Suppl 1:A18-A24.
PMID: 31326255 DOI: 10.1016/j.vaccine.2019.07.035

INTRODUCTION: Although the current pandemic of cholera originated in Asia, reports of cholera cases and outbreaks in the region are sparse. To provide a sub-regional assessment of cholera in South and Southeast Asia, we collated published and unpublished data from existing surveillance systems from Bangladesh, Cambodia, India, Malaysia, Nepal, Pakistan, Philippines, Thailand and Vietnam.
METHODS: Data from existing country surveillance systems on diarrhea, acute watery diarrhea, suspected cholera and/or confirmed cholera in nine selected Asian countries (Bangladesh, Cambodia, India, Malaysia, Nepal, Pakistan, Philippines, Thailand and Vietnam) from 2011 to 2015 (or 2016, when available) were collated. We reviewed annual cholera reports from WHO and searched PubMed and/or ProMED to complement data, where information is not completely available.
RESULTS: From 2011 to 2016, confirmed cholera cases were identified in at least one year of the 5- or 6-year period in the countries included. Surveillance for cholera exists in most countries, but cases are not always reported. India reported the most number of confirmed cases with a mean of 5964 cases annually. The mean number of cases per year in the Philippines, Pakistan, Bangladesh, Malaysia, Nepal and Thailand were 760, 592, 285, 264, 148 and 88, respectively. Cambodia and Vietnam reported 51 and 3 confirmed cholera cases in 2011, with no subsequent reported cases.
DISCUSSION AND CONCLUSION: We present consolidated results of available surveillance in nine Asian countries and supplemented these with publication searches. There is paucity of readily accessible data on cholera in these countries. We highlight the continuing existence of the disease even in areas with improved sanitation and access to safe drinking water. Continued vigilance and improved surveillance in countries should be strongly encouraged.

Fulltext Plasmodium knowlesi infecting humans in Southeast Asia: What's next?

Jeyaprakasam NK, Liew JWK, Low VL, Wan-Sulaiman WY, Vythilingam I

PLoS Negl Trop Dis, 2020 12;14(12):e0008900.
PMID: 33382697 DOI: 10.1371/journal.pntd.0008900

Plasmodium knowlesi, a simian malaria parasite, has been in the limelight since a large focus of human P. knowlesi infection was reported from Sarawak (Malaysian Borneo) in 2004. Although this infection is transmitted across Southeast Asia, the largest number of cases has been reported from Malaysia. The increasing number of knowlesi malaria cases has been attributed to the use of molecular tools for detection, but environmental changes including deforestation likely play a major role by increasing human exposure to vector mosquitoes, which coexist with the macaque host. In addition, with the reduction in human malaria transmission in Southeast Asia, it is possible that human populations are at a greater risk of P. knowlesi infection due to diminishing cross-species immunity. Furthermore, the possibility of increasing exposure of humans to other simian Plasmodium parasites such as Plasmodium cynomolgi and Plasmodium inui should not be ignored. We here review the current status of these parasites in humans, macaques, and mosquitoes to support necessary reorientation of malaria control and elimination in the affected areas.
