Background: Myanmar, one of the high tuberculosis (TB) burden countries, is in serious need of research work to develop strategies aiming to tackle the problem. Conducting a study on the knowledge of the population will help understand the flaws in the National TB Control Program (NTP), and how to correct them, and further strategic planning to reach the goals of Sustainable Development Goals. Aims: The aim of the study was to access sociodemographic characteristics, knowledge, and behavioral practice of TB among the community members in Ngar Syu Taung Village, Hlegu Township. This is a cross-sectional descriptive study. The number of defined person was 200. Methods: Nonprobability convenience sampling method was used. Data collection method used was face-to-face interviewing method using questionnaires. They were collected by house officers as a part of the community medicine training program. Results: Less than half of the respondents were not aware of TB meningitis (41%) and TB osteomyelitis (49%) and they are not aware that diabetic patients are one of the commonly infected people (41.5%). Furthermore, less than one-third of the patients know that TB can infect the gut (23%) and cause bowel obstruction (30.5%). Conclusions: Wrong ideas should be tackled, and lacking knowledge should be enlightened. Nationwide studies using stronger study designs are also urgently needed. Implementing these evidence into NTP is necessary for Myanmar, to escape from being a TB high-burden country.

| Introduction|| |
Tuberculosis (TB) is a common disease in Myanmar. The causal organisms are various strains of mycobacteria, usually Mycobacterium tuberculosis in humans. Due to its air-born transmission as the primary mode of transmission, TB has become the disease of community concern for Myanmar. Proper research is needed to explore the knowledge of the community members on TB.
In 2015, World Health Organization (WHO) estimated 10.4 million new (incident) TB cases worldwide, of which 5.9 million (56%) were among men, 3.5 million (34%) among women, and 1.0 million (10%) among children. People living with human immunodeficiency virus (HIV) accounted for 1.2 million (11%) of all new TB cases.
According to WHO TB Report 2016, Myanmar is included in all three categories of TB high-burden countries in the world: TB, multidrug-resistant TB (MDR-TB), and TB/HIV. In 2015, mortality (excludes HIV + TB) is 49 per 100,000 population. Estimated percentage of new TB cases with MDR/rifampicin-resistant TB (RR-TB) was 5.1%, of previously treated TB cases 27%. Estimated number of MDR/RR-TB cases among notified pulmonary TB cases was 9000. There were 43 MDR/RR-TB cases tested for resistance to second-line drugs.
According to Myanmar Demographic and Health Survey (MDHS) 2015–16, more than 9 in 10 women and men aged 15–49 have heard of TB. The lowest level of knowledge about TB is among women and men in Shan State, where only two-thirds have heard of TB. Knowledge of TB is also relatively low among those with no education, with only about seven in ten have heard of TB.
We have done a survey on knowledge on TB at the Ngar Syu Taung village during our training period to Hlegu Township for the community medicine field training as part of the house officer training. The training period was from May 8, 2017, to May 19, 2017.
| Methods|| |
This is a cross-sectional descriptive study. The number of defined persons was 200.
Selection and description of participants
Study area assigned was Ngar Syu Taung village, Hlegu Township. The village is located within Yangon Division of Myanmar. In 2016, there were 69 old cases of TB per 100,000 population and 69 new cases of TB per 100,000 population. Nonprobability convenience sampling method was used for the selection of participants with an age of ≥18 years of both sexes.
Questionnaire development and data collection
The questionnaire was developed by 11 house officers, and a brief pilot study was conducted among the other 34 house officers and reviewed by a supervisor.
The survey program was conducted by 33 house officers. Data collection method used was face-to-face interviewing method using questionnaires.
The data were analyzed by computer processing using Statistical Package for the Social Sciences (SPSS) 16.0 (SPSS Inc, Chicago, USA).
The objectives of the study were explained before asking the questionnaires. It was made sure that there was absolute confidentiality of the information during and after conducting the study. However, permission from the Ethics Committee was not obtained because this study is not an interventional study.

| Discussion|| |
This survey has revealed important information regarding the knowledge and behavioral practice of the Ngar Syu Taung village population. Using this information, appropriate intervention plans should be done to tackle the problems regarding TB.
Only 54% (n = 200) of the respondents have good knowledge, which is a really low value, as Myanmar is a country with very high TB burden. Intervention is required urgently to increase the knowledge of the rest (46%) (n = 200) of the respondents. A survey conducted on 2016 at the same village yielded 61% of high knowledge and 39% of low knowledge. (paper submitted to the University of Medicine 1, Yangon; unpublished private collection; unreferenced). Compared to that study, the knowledge level has slightly declined this year. One intervention recommended should be health education as a study conducted in Vietnam, a South-east Asian country like Myanmar has found that receiving health education can increase the knowledge on TB. Health education through radios and television is urgently suggested as they are the major source of information (90%) (n = 200) and the knowledge level will continue to decline if there is no further intervention.
However, in a nationwide study, MDHS 2015–16, 71% of women and 63% of men know that TB spreads through coughing, compared to 95.5% (n = 200) in this study. This means that there are many regions in Myanmar that have far worse knowledge on TB than this studied village.
Regarding the topics, tuberculous meningitis, tuberculous osteomyelitis, and tuberculous intestinal obstruction should also be emphasized with the same level as the another topic as they are usually not included in most health education programs in Myanmar. Awareness should also be raised regarding the association between diabetes and TB. Surveys conducted last year in the same village, as well as the nearby Phaung Gyi Village, yielded a similar result. (paper submitted to the University of Medicine 1, Yangon; unpublished private collection; unreferenced).
Another important fact is that 27.50% (n = 200) of the respondents agreed to self-medication, which is a dangerous problem, as drug resistance may arise. Almost 34.5% (n = 200) agreed to traditional medicine, which is also harmful to the individual as well as for the public. A similar finding was found from a study conducted at Ethiopia where 45.3% (n = 422) of the study population prefer traditional healers for treatment. Surveys conducted in the same village, as well as the nearby Phaung Gyi Village, yielded a similar result. (paper submitted to the University of Medicine 1, Yangon; unpublished private collection; unreferenced). Local traditional practitioners and drug stores should be informed and given information not to give traditional treatment and drugs to people suspected of suffering from TB.
Regarding the behavioral practice of the respondents, 25% (n = 200) were still smoking, so health education programs aimed at smoking cessation are highly recommended. Furthermore, their behavioral practices were mostly wrong, not covering the mouth with a handkerchief when they cough (37%) (n = 200), not using a mask when they are ill (70.5%) (n = 200), and discarding the sputum anywhere (48%) (n = 200). This could lead to high risk of transmission among the population. Health education intervention is urgently needed to correct these wrong practices. A study conducted at three main industrial zones of Yangon, Myanmar, revealed a similar result.
| Conclusion|| |
Our study has revealed some wrong idea and lack of knowledge in certain areas regarding TB. These wrong ideas should be tackled, and lacking knowledge should be enlightened. For doing so, we have found out the most effective way as television and radio. Cooperation between Ministry of Health and Sports and Ministry of Information is needed for broadcasting health education programs on television and radio.
Moreover, nationwide studies using stronger study designs are also urgently needed. Interventional studies, preferably randomized control trials, are also recommended to have a high-quality evidence. A systematic review of all these studies would be the next step recommended. Implementing these evidence into NTP as included in the Strategic Direction III: Intensified Research and Innovation of the 2016-2020 National Strategic Plan for TB Control, with a strong advocacy, communication, and social mobilization strategy, is absolutely necessary for our country, Myanmar, to escape from being a TB high-burden country.
