Wai YZ, Fiona Chew LM, Mohamad AS, Ang CL, Chong YY, Adnan TH, et al.

Int J Ophthalmol, 2018;11(10):1685-1690.
PMID: 30364221 DOI: 10.18240/ijo.2018.10.17

AIM: To report the incidence, risk factors and visual outcomes for postoperative endophthalmitis (POE) based on 7-year data from the Malaysian Ministry of Health Cataract Surgery Registry (MOH CSR).
METHODS: Data was collected from the web-based MOH CSR. All consecutive cataract surgery patients from 1st June 2008 to 31st December 2014 were identified. Exclusion criteria were traumatic cataract or previous ocular surgery. Demographic data, ocular co-morbidities, intraoperative details and postoperative visual acuity (VA) at final ophthalmological follow-up were noted. All eyes were taken for analysis. Subjects with POE were compared against subjects with no POE for risk factor assessment using multiple logistic regressions.
RESULTS: A total of 163 503 subjects were screened. The incidence of POE was 0.08% (131/163 503). Demographic POE risk factors included male gender (OR: 2.121, 95%CI: 1.464-3.015) and renal disease (OR: 2.867, 95%CI: 1.503-5.467). POE risk increased with secondary causes of cataract (OR: 3.562, 95%CI: 1.740-7.288), uveitis (OR: 11.663, 95%CI: 4.292-31.693) and diabetic retinopathy (OR: 1.720, 95%CI: 1.078-2.744). Intraoperative factors reducing POE were shorter surgical time (OR: 2.114, 95%CI: 1.473-3.032), topical or intracameral anaesthesia (OR: 1.823, 95%CI: 1.278-2.602), posterior chamber intraocular lens (PCIOL; OR: 4.992, 95%CI: 2.689-9.266) and foldable IOL (OR: 2.276, 95%CI: 1.498-3.457). POE risk increased with posterior capsule rupture (OR: 3.773, 95%CI: 1.915-7.432) and vitreous loss (OR: 3.907, 95%CI: 1.720-8.873). Postoperative VA of 6/12 or better was achieved in 15.27% (20/131) subjects with POE.
CONCLUSION: This study concurs with other studies regarding POE risk factors. Further strengthening of MOH CSR data collection process will enable deeper analysis and optimization of POE treatment.

Fulltext International Consortium on Mammographic Density: Methodology and population diversity captured across 22 countries

McCormack VA, Burton A, dos-Santos-Silva I, Hipwell JH, Dickens C, Salem D, et al.

Cancer Epidemiol, 2016 Feb;40:141-51.

Mammographic density (MD) is a quantitative trait, measurable in all women, and is among the strongest markers of breast cancer risk. The population-based epidemiology of MD has revealed genetic, lifestyle and societal/environmental determinants, but studies have largely been conducted in women with similar westernized lifestyles living in countries with high breast cancer incidence rates. To benefit from the heterogeneity in risk factors and their combinations worldwide, we created an International Consortium on Mammographic Density (ICMD) to pool individual-level epidemiological and MD data from general population studies worldwide. ICMD aims to characterize determinants of MD more precisely, and to evaluate whether they are consistent across populations worldwide. We included 11755 women, from 27 studies in 22 countries, on whom individual-level risk factor data were pooled and original mammographic images were re-read for ICMD to obtain standardized comparable MD data. In the present article, we present (i) the rationale for this consortium; (ii) characteristics of the studies and women included; and (iii) study methodology to obtain comparable MD data from original re-read films. We also highlight the risk factor heterogeneity captured by such an effort and, thus, the unique insight the pooled study promises to offer through wider exposure ranges, different confounding structures and enhanced power for sub-group analyses.

Fulltext Circulating plasma phospholipid fatty acids and risk of pancreatic cancer in a large European cohort

Matejcic M, Lesueur F, Biessy C, Renault AL, Mebirouk N, Yammine S, et al.

Int J Cancer, 2018 Nov 15;143(10):2437-2448.
PMID: 30110135 DOI: 10.1002/ijc.31797

There are both limited and conflicting data on the role of dietary fat and specific fatty acids in the development of pancreatic cancer. In this study, we investigated the association between plasma phospholipid fatty acids and pancreatic cancer risk in the European Prospective Investigation into Cancer and Nutrition (EPIC) cohort. The fatty acid composition was measured by gas chromatography in plasma samples collected at recruitment from375 incident pancreatic cancer cases and375 matched controls. Associations of specific fatty acids with pancreatic cancer risk were evaluated using multivariable conditional logistic regression models with adjustment for established pancreatic cancer risk factors. Statistically significant inverse associations were found between pancreatic cancer incidence and levels of heptadecanoic acid (ORT3-T1 [odds ratio for highest versus lowest tertile] =0.63; 95%CI[confidence interval] = 0.41-0.98; ptrend = 0.036), n-3 polyunsaturated α-linolenic acid (ORT3-T1 = 0.60; 95%CI = 0.39-0.92; ptrend = 0.02) and docosapentaenoic acid (ORT3-T1 = 0.52; 95%CI = 0.32-0.85; ptrend = 0.008). Industrial trans-fatty acids were positively associated with pancreatic cancer risk among men (ORT3-T1 = 3.00; 95%CI = 1.13-7.99; ptrend = 0.029), while conjugated linoleic acids were inversely related to pancreatic cancer among women only (ORT3-T1 = 0.37; 95%CI = 0.17-0.81; ptrend = 0.008). Among current smokers, the long-chain n-6/n-3 polyunsaturated fatty acids ratio was positively associated with pancreatic cancer risk (ORT3-T1 = 3.40; 95%CI = 1.39-8.34; ptrend = 0.007). Results were robust to a range of sensitivity analyses. Our findings suggest that higher circulating levels of saturated fatty acids with an odd number of carbon atoms and n-3 polyunsaturated fatty acids may be related to lower risk of pancreatic cancer. The influence of some fatty acids on the development of pancreatic cancer may be sex-specific and modulated by smoking.

Fulltext Circulating concentrations of vitamin D in relation to pancreatic cancer risk in European populations

van Duijnhoven FJB, Jenab M, Hveem K, Siersema PD, Fedirko V, Duell EJ, et al.

Int J Cancer, 2018 Mar 15;142(6):1189-1201.
PMID: 29114875 DOI: 10.1002/ijc.31146

Evidence from in vivo, in vitro and ecological studies are suggestive of a protective effect of vitamin D against pancreatic cancer (PC). However, this has not been confirmed by analytical epidemiological studies. We aimed to examine the association between pre-diagnostic circulating vitamin D concentrations and PC incidence in European populations. We conducted a pooled nested case-control study within the European Prospective Investigation into Cancer and Nutrition (EPIC) and the Nord-Trøndelag Health Study's second survey (HUNT2) cohorts. In total, 738 primary incident PC cases (EPIC n = 626; HUNT2 n = 112; median follow-up = 6.9 years) were matched to 738 controls. Vitamin D [25(OH)D2 and 25(OH)D3 combined] concentrations were determined using isotope-dilution liquid chromatography-tandem mass spectrometry. Conditional logistic regression models with adjustments for body mass index and smoking habits were used to estimate incidence rate ratios (IRRs) and 95% confidence intervals (95%CI). Compared with a reference category of >50 to 75 nmol/L vitamin D, the IRRs (95% CIs) were 0.71 (0.42-1.20); 0.94 (0.72-1.22); 1.12 (0.82-1.53) and 1.26 (0.79-2.01) for clinically pre-defined categories of ≤25; >25 to 50; >75 to 100; and >100 nmol/L vitamin D, respectively (p for trend = 0.09). Corresponding analyses by quintiles of season-standardized vitamin D concentrations also did not reveal associations with PC risk (p for trend = 0.23). Although these findings among participants from the largest combination of European cohort studies to date show increasing effect estimates of PC risk with increasing pre-diagnostic concentrations of vitamin D, they are not statistically significant.

The influence of permethrin-impregnated bednets and mass drug administration on the incidence of Plasmodium falciparum malaria in children in Sabah, Malaysia

Hii JL, Vun YS, Chin KF, Chua R, Tambakau S, Binisol ES, et al.

Med Vet Entomol, 1987 Oct;1(4):397-407.
PMID: 2979556

A small-scale trial was carried out in the Upper Kinabatangan district of Sabah, Malaysia, to determine the effect of using permethrin-impregnated bednets on malaria transmission. A total of 306 nylon bednets with cotton borders, impregnated at a dose estimated to have been 0.062 g permethrin/m2 of nylon netting, were distributed to 139 households in five villages. At the time of distributing bednets, mass drug administration with Fansidar plus primaquine was also administered to the human population to clear all parasitaemias due to Plasmodium falciparum Welch. In another village, for comparison, mass drug administration was the only intervention. After intervention measures in December 1984 and January 1985, the parasite rates in children declined in all villages during the first month, significantly more in the villages with impregnated bednets than in the control, thus proving that the nets had an impact on malaria. However, after about 2 months, parasite rates started to increase again. After 4-6 months, parasite rates in the villages with bednets approached the rate in the control village without nets. The increase in parasite rates was paralleled by a significant deterioration in the quality, physical condition and the degree of non-utilization of bednets. Entomological evaluation proved the efficacy of permethrin-impregnated nets for controlling Anopheles balabacensis Baisas and other anophelines. Bioassays (1 h exposure) of permethrin-impregnated bednets gave 100% mortality initially and 44-61% mortality after 85-106 days. Mosquito collections in treated bednets were significantly reduced for at least 217 days. The project failed to achieve prolonged suppression of malaria transmission for a combination of entomological, sociological and practical reasons which are discussed in relation to the objectives and implementation of future bednet studies.

Gan GG, Iyadorai T, Sulaiman NY, Hussein N, Ariffin H

Clin Transplant, 2024 Jun;38(6):e15375.
PMID: 39031785 DOI: 10.1111/ctr.15375

BACKGROUND: Cytomegalovirus infection (CMV) is a common complication after allogeneic hematopoietic stem cell transplantation (AHSCT). CMV infection increases transplantation costs; however, the extent of the financial burden may vary in different countries. This study aims to determine the clinical and economic impact of CMV infection in patients undergoing AHSCT in a middle-income country.
METHODS: A total of 150 adult and pediatric patients post-AHSCT were included for analysis. In addition to incidence of CMV infections, data on graft versus host disease (GVHD) were also collected. Standard hospital charges for AHSCT and any additional transplantation-related expenditure within 12 months were also retrieved in 104 patients.
RESULTS: CMV infection, acute GVHD and chronic GVHD occurred in 38.7%, 60.7%, and 22.0% of patients, respectively. Patients with CMV infections had higher readmission rates compared to those who did not (67.2% vs. 47.8%; p = 0.020). Additional expenditure was seen in HLA-haploidentical AHSCT and CMV infection (MYR11 712.25/USD2 504.49; p

Antibiotics are the pillar of surgery from prophylaxis to treatment; any failure is potentially a leading cause for increased morbidity and mortality. Robust data on the burden of SSI especially those due to antimicrobial resistance (AMR) show variable rates between countries and geographical regions but accurate estimates of the incidence of surgical site infections (SSI) due to AMR and its related global economic impact are yet to be determined. Quantifying the burden of SSI treatment is an incentive to sensitize governments, healthcare systems, and the society to invest in quality improvement and sustainable development. However in the absence of a unified epidemiologically sound infection definition of SSI and a well-designed global surveillance system, the end result is a lack of accurate and reliable data that limits the comparability of estimates between countries and the possibility of tracking changes to inform healthcare professionals about the appropriateness of implemented infection prevention and control strategies. This review aims to highlight the reported gaps in surveillance methods, epidemiologic data, and evidence-based SSI prevention practices and in the methodologies undertaken for the evaluation of the economic burden of SSI associated with AMR bacteria. If efforts to tackle this problem are taken in isolation without a global alliance and data is still lacking generalizability and comparability, we may see the future as a race between the global research efforts for the advancement in surgery and the global alarming reports of the increased incidence of antimicrobial-resistant pathogens threatening to undermine any achievement.

PMID: 34752486 DOI: 10.1371/journal.pone.0259782

Postpartum depression (PPD) is one of the mental health complications that may arise following childbirth. This cross-sectional study explores the association between socioeconomic factors and PPD literacy with PPD incidence in 350 participants (mean age: 30.58±4.72 years) at one to six months postpartum, who attended the Kuala Lumpur Health Clinic from May to October 2020. PPD incidence and literacy were assessed using the validated Malay versions of the Edinburgh Postpartum Depression Scale (EPDS) and the Postpartum Depression Literacy Scale (PoDLiS), respectively. The participants' socioeconomic characteristics were collected using a self-administered questionnaire. Chi-square tests were performed to determine the association between these factors and PPD incidence. Binary logistic regression models were used to determine the odds ratios (OR). The incidence of postpartum depressive symptoms was 14.29%. Those with low household income were twice likely to have PPD symptoms (OR:2.58, 95% CI:1.23-5.19; p = 0.01) than those with higher incomes. Unemployment (i.e., participants who were housewives/homemakers) was associated with higher PPD incidence (Χ2(2, 350) = 6.97, p = 0.03), but it was not a significant PPD predictor. In conclusion, PPD incidence in the sample of Kuala Lumpur postpartum mothers is significantly associated with low household income. Other socioeconomic characteristics, including PPD literacy, were not significant predictors of PPD incidence.

Fulltext Trichomoniasis in cosmopolitan Malaysia: is it under control or is it under diagnosed?

Amal RN, Aisah MY, Fatmah MS, Hayati MI

Southeast Asian J Trop Med Public Health, 2010 Nov;41(6):1312-5.
PMID: 21329303

In a prospective, observational study, 380 women attending a family planning (LPPKN) clinic and Sexually Transmitted Diseases (STD) clinic in Kuala Lumpur between January 2008 and November 2008 were enrolled. Patient information was obtained from the medical records and patients voluntarily completed questionnaires. Three vaginal swabs from the posterior fornix were taken from each patient examined. Different staining methods and cultivation in Diamonds medium were performed on the collected samples. Study subjects recruited in this survey were mostly young, with a geometric mean ages of 37.31 years (LPPKN clinic) and 32.06 years (STD clinic). Malay, Chinese, Indians and others ethnic groups accounted for 91, 4, 2 and 3%, respectively, at the LPPKN clinic. At the STD clinic, almost all subjects were Chinese. The prevalence rate of trichomoniasis was 0.36% at the LPPKN clinic and 0.0% at the STD clinic. Our findings suggested no association between contraceptive methods used and trichomoniasis infection at the LPPKN clinic. At the STD clinic, it was found a high risk for STD acquisition was not associated with trichomoniasis positivity. The data demonstrated the prevalence of trichomoniasis was very low at LPPKN clinic and absent at STD clinic. The high prevalence rates of other STD among sex workers found in this survey suggest the need for more active interventions focused on this group.

PMID: 8525403

Renal biopsy is essential in the management of renal parenchymal diseases. Thus far there is no publish report on the pattern of glomerulonephritis in Kelantan. We decided to establish the pattern of glomerulonephritis in Kelantan and use this information as our reference in future studies. Records of patients who had proven glomerulonephritis histologically were analysed. Their biological data, clinical presentation, etiology and clinicopathological pattern were studied. Where appropriate mean and standard deviation were calculated. A total of 74 biopsies were performed during the study period (between January 1991 and December 1993), out of which 72 biopsies (97.3%) were considered suitable for analysis. The male to female ratio was 1:1.1. Mean age at presentation was 27.6 +/- 12.2 years. Nephrotic syndrome was the commonest clinical presentation (65.3%). The main underlying cause was systemic lupus erythematosus (50%) followed by primary glomerulonephritis. Histologically, IgA nephropathy and minimal change disease were the main patterns among patients with primary glomerulonephritis while diffuse proliferative glomerulonephritis was the commonest pattern among patients with lupus nephritis. Hence the pattern of glomerulonephritis is similar to other reported series. The procedure is considered safe and has a high success rate.

PMID: 20578464

Pneumocystis pneumonia (PCP) has become the most common opportunistic infection in HIV/AIDS patients with a CD4 count < or = 200. The incidence of PCP has declined as a result of prophylaxis and better highly active antiretroviral therapy (HAART). The objective of this study was to review the demographic data of HIV patients diagnosed clinically as having PCP at the Hospital Raja Perempuan Zainab II (HRPZ II) in Malaysia. This was a prospective study. All HIV patients admitted to HRPZ II with respiratory symptoms were enrolled in this study after giving informed consent. Their demographic data were collected. The total number of HIV patients reviewed in this study was 107. Nearly 60% of patients were clinically diagnosed as having pneumocystis pneumonia based on their signs, symptoms and chest x-ray findings. A CD4 count was available in 83 out of 107 patients. The fifty-three percent of patients(44) had a CD4 < 200 and were clinically diagnosed as having pneumocystis pneumonia. Thirty percent had a CD4 < 200 but did not have clinical pneumocystis pneumonia. Sixteen point nine percent had a CD4 > 200 and had clinical pneumocystis pneumonia, three of whom had received HAART, four patients had received prophylaxis. Overall, 94 patients (87.8%) received prophylaxis for pneumocystis pneumonia. Thirty-three patients (30.8%) received HAART. The occurrence of pneumocystis pneumonia was common before full implementation of HAART. Pneumocystis pneumonia can occur in patients with a CD4 >200.

Fulltext Toxoplasmosis in HIV/AIDS: a living legacy

Nissapatorn V

Southeast Asian J Trop Med Public Health, 2009 Nov;40(6):1158-78.
PMID: 20578449

Toxoplasmosis has historically been considered one of the most important opportunistic infections detected in HIV/AIDS patients. The prevalence rates of latent Toxoplasma infections in HIV-infected patients has been found to vary greatly from 3% to 97%. Prevalence has been found to be related to ethnicity, certain risk factors, and reactivation of toxoplasmosis. Prior to antiretroviral therapy, toxoplasmic encephalitis (TE) was the most common focal cerebral lesion detected in AIDS patients with Toxoplasma infection, occurring in approximately half of Toxoplasma-seropositive patients. Other forms of dissemination have also been reported in AIDS patients in sites such as the eyes, lungs, heart and spinal cord. Anti-Toxoplasma therapy and chemoprophylaxis have shown effectiveness in reducing the incidence of TE, while noncompliance has been identified as a cause of relapse in these settings. Toxoplasmosis is one of the most common neuropathological complications found at autopsy. Rapid progress in the development of highly active antiretroviral therapy (HAART) has changed the observed patterns with TE, for which there has been a marked decrease in overall incidence. Subsequently, TE has been found to be significantly associated with the so-called "neurological immune restoration inflammatory syndrome" (NIRIS). Toxoplasma screening programs are recommended for all newly diagnosed HIV-positive patients. Chemoprophylaxis should be considered in HIV-infected patients who have a CD4 < 200 cells/mm3, particularly in settings where resources are limited and there is not access to HAART. TE remains a cause of morbidity and mortality among AIDS patients.

Clinical features and risk factors for HIV encephalopathy in children

Hamid MZ, Aziz NA, Zulkifli ZS, Norlijah O, Azhar RK

Southeast Asian J Trop Med Public Health, 2008 Mar;39(2):266-72.
PMID: 18564712

A prospective cohort study was conducted to determine the incidence of progressive encephalopathy (PE) and its associated clinical manifestations amongst a cohort of HIV infected children attending the HIV/AIDS clinic of the Pediatric Institute, Kuala Lumpur Hospital, Malaysia. Neurological and neurobehavioral assessments were performed in 55 children with HIV over a 24-month study period. Parameters assessed were physical and neurological assessments, CD4 counts, CD4 percentages, RNA viral loads and an IQ assessment at four monthly intervals. PE was diagnosed when patient developed at least one of the definitive criteria for PE based on the Consensus of Pediatric Neurology/Psychology Working Group, AIDS Clinical Trial 1996. The incidence of encephalopathy was 18.2% (n = 10) in 2002. All the patients had hepatosplenomegaly, lymphadenopathy, abnormal deep tendon reflexes and five had impairment in brain growth. The CD4 counts and CD4 percentages were more likely to be associated with PE compared to the non-PE group.

Southeast Asian J Trop Med Public Health, 2006;37 Suppl 3:153-60.
PMID: 17547073

A total of 136 patients, 67 HIV, 69 diabetes mellitus (DM) with or without (+/-) end-stage renal disease (ESRD), were registered for tuberculosis treatment at the National Tuberculosis Center (NTBC) from May to December, 2003. Ages ranged from 21-78 years (median 57.7 years) in TB/DM patients, and 21-62 (mean 37.6 +/- 8.3 years) in TB/HIV patients. TB was significantly found in younger and single HIV patients, but in older and married DM patients (p<0.05). Male patients in both groups were strongly associated with TB, while females more commonly had TB with DM (p<0.05). The majority of these patients were Malays, unemployed, and resided in Kuala Lumpur territory; however, no statistically significant difference was found between the 2 groups. Smoking, IVDUs and hepatitis C virus (HCV) infection were more significantly found in TB/HIV patients and further analysis showed that pulmonary TB was strongly associated with HCV infection in these patients (p<0.05). Pulmonary TB (62; 89.9%) was the most common type found in both groups and was a markedly more common disease location in TB/DM patients, while extrapulmonary TB (21; 31.3%) and miliary TB (14; 21%) were significantly higher in TB/HIV patients. Cough with or without sputum, fever and loss of appetite and/or weight were common clinical presentations in both groups. Nevertheless, fever (54; 80.6%) and lymphadenopathy (17; 25.4%) were significantly related to TB/HIV patients (p<0.05). Interestingly, the presence of BCG vaccination and positive tuberculin skin test were stronger in TB/HIV (27; 40.3%) and TB/DM (20; 29%) patients, respectively (p<0.05). Overall, regular 6-, 9- and 12-months' anti-tubercular therapy (ATT) were routine practice, and EHRZ+B6 was the most common regimen used. The highest percentage of patients with treatment success were in both groups with 6 months' ATT; however, a significantly higher percentage was found in TB/DM (24; 34.8%) than TB/HIV (13; 19.4%) (p<0.05). A success rate of 15 (21.7%) was noted for TB/DM patients with 9 months' ATT, which was similar to both groups with the 12-month regimen. A higher percentage failure rate (lost to follow-up) was seen in TB/HIV (19; 28.4%) patients. Nine patients were reported to have anti-tubercular-drug side-effects, such as drug-induced hepatitis, blurred vision, and skin rash. No cases of drug resistance or death were notified among these patients.

Extrapulmonary tuberculosis in Peninsular Malaysia: retrospective study of 195 cases

Nissapatorn V, Kuppusamy I, Rohela M, Anuar AK, Fong MY

Southeast Asian J Trop Med Public Health, 2004;35 Suppl 2:39-45.
PMID: 15906632

During a 2-year retrospective study, 195 non-HIV-infected patients with extrapulmonary tuberculosis (EPT) were diagnosed at the National Tuberculosis Center, Kuala Lumpur, representing 10% of all patients with tuberculosis. Their mean age was 39 (+/- SD) 14 years old (range 14-81). The largest age group was 25-34 years, while 78.5% were less than 50 years of age. The subjects were mainly female (50.3%), Malay (49.2%), married (61.5%), resided in Kuala Lumpur (51.0%), and were unemployed (50.3%). Regarding risk factors, they were smokers and/or alcohol users (21.0%), and injecting drug users (IDUs) (5.1%); they also had history of tuberculosis (3.6%) and contact with TB patients (9.2%). Lymphadenopathy was the most common sign (45.6%) shown in the medical records. 42% of x-ray findings (chest, spine, and hip) showed signs consistent with tuberculosis, while histopathology was the most useful diagnostic tool (52.3%) and lymph node was the most frequent specimen used (35.0%) in this study. The three main sites of involvement were lymph nodes (42.6%), miliary and disseminated (19.5%), and pleura (12.8%). The outcome of this study showed 72.8% of these patients had completed treatment for at least 6 months, whilst, only 4.6% of patients were still undergoing treatment, and unfortunately, 22.6% of them showed non-adherence to anti-tubercular therapy at a duration of less than 6 months. However, no MDR-TB or death cases were reported or registered in this study.

Current status of filariasis in Malaysia

Marzhuki MI, Tham AS, Poovaneswari S

Southeast Asian J Trop Med Public Health, 1993;24 Suppl 2:10-4.
PMID: 7973937

The Filariasis Control Program was established more than 30 years ago in the country and the disease is still a public health problem in some states. Since 1983, a total of 17 filariasis control teams were formed throughout the country to carry out filariasis control work. The teams conduct house and population censuses, nocturnal mass blood surveys and treatment of microscopically confirmed cases. Individual case follow-up is being carried out after 3-5 months while the locality is resurveyed after about 2-3 years. During the years 1988 to 1990, there appeared to be a decreasing trend in the number of filariasis cases detected countrywide. In 1991, brugian filariasis accounted for 92% of the cases detected. The microfilaria rate (MFR) also showed a decreasing trend countrywide for the years 1988 (0.57%) to 1990 (0.35%) but there was an increase in 1991 although it remained well below the 5% MFR targeted in the program objective, In 1991, the filariasis control teams and the district multi-purpose teams collected a total of 167, 151 blood slides out of which 871 were found to be positive for microfilaria. To determine the true endemicity of filariasis in the country, the malaria district multi-purpose teams are also utilized to assist in probe surveys in new areas of the district. Two species of filarial worms, namely Brugia malayi and Wuchereria bancrofti, and the mosquito vectors belonging to the Anopheles and Mansonia genera are involved in the transmission of filariasis in Malaysia. Monkeys and domestic cats are the reservoir hosts for the subperiodic strain of B. malayi.
