Efficacy of LD Bio Aspergillus ICT Lateral Flow Assay for Serodiagnosis of Chronic Pulmonary Aspergillosis.

Background: The diagnosis of CPA relies on the detection of the IgG Aspergillus antibody, which is not freely available, especially in resource-poor settings. Point-of-care tests like LDBio Aspergillus ICT lateral flow assay, evaluated in only a few studies, have shown promising results for the diagnosis of CPA. However, no study has compared the diagnostic performances of LDBio LFA in setting of tuberculosis endemic countries and have compared it with that of IgG Aspergillus. Objectives: This study aimed to evaluate the diagnostic performances of LDBio LFA in CPA and compare it with existing the diagnostic algorithm utilising ImmunoCAP IgG Aspergillus. Methods: Serial patients presenting with respiratory symptoms (cough, haemoptysis, fever, etc.) for >4 weeks were screened for eligibility. Relevant investigations, including direct microscopy and culture of respiratory secretions, IgG Aspergillus, chest imaging, etc., were done according to existing algorithm. Serums of all patients were tested by LDBio LFA and IgG Aspergillus (ImmunoCAP Asp IgG) and their diagnostic performances were compared. Results: A total of 174 patients were included in the study with ~66.7% patients having past history of tuberculosis. A diagnosis of CPA was made in 74 (42.5%) of patients. The estimated sensitivity and specificity of LDBio LFA was 67.6% (95% CI: 55.7–78%) and 81% (95% CI: 71.9–88.2%), respectively, which increased to 73.3% (95% CI: 60.3–83.9%) and 83.9% (95% CI: 71.7–92.4%), respectively, in patients with a past history of tuberculosis. The sensitivity and specificity of IgG Aspergillus was 82.4% (95% CI: 71.8–90.3%) and 82% (95% CI: 73.1–89%); 86.7% (95% CI: 75.4–94.1%) and 80.4% (95% CI: 67.6–89.8%), in the whole group and those with past history of tuberculosis, respectively. Conclusions: LDBio LFA is a point-of-care test with reasonable sensitivity and specificity. However, further tests may have to be done to rule-in or rule-out the diagnosis of CPA in the appropriate setting.

Time for Isoniazid Pharmacogenomic-Guided Therapy of Tuberculosis Based on NAT2 Acetylation Profiles in India.

Tuberculosis (TB), caused by a bacterial pathogen Mycobacterium tuberculosis, is a highly contagious infectious disease. India ranks top in TB burden among other countries in the world. The current treatment of TB in India includes isoniazid (INH) as the first-line drug, based on the "one dose fits all'' concept. It is widely known that INH is not equally tolerated by all patients, as the metabolization process of INH is highly dependent on the acetylation profile of an individual based on the pharmacogenomic profile of the N-acetyltransferase (NAT2) gene. Also, several experimental studies in several TB endemic countries have established that redosing of INH based on genetic profiles of TB patients of the NAT2 can help in effective TB treatment and minimize adverse drug reactions (ADRs). Moreover, acetylation phenotype-based INH dosing has been shown to be cost-effective as well as successful in terms of treatment outcomes and the increase in the quality of life of the patients. Considering a genetically heterogenous population with high vulnerability to TB, we here argue that India could lead in establishing a pharmacogenomic-guided therapy (PGT) under the INH-NAT2 model. With such an approach, not only could an innovative step towards 'End-TB' by the year 2025 be taken but a personalized medicine approach for TB treatment be initiated in India, particularly in tribal communities.

Prevalence of latent tuberculosis infection among pre-clinical and clinical medical students using QuantiFERON-TB gold plus and tuberculin skin test at a teaching hospital in Thailand: A cross-sectional study

BackgroundHealthcare workers are considered to be at a higher risk of acquiring tuberculosis (TB) infection than the general population. Clinical medical students are part of the healthcare team and clinical practice are done during their clinical rotation. They could be exposed to similar occupational risks as the healthcare workers. Most students who become infected have latent tuberculosis infection (LTBI) and may not exhibit any clinical symptoms. Some students with LTBI can progress to TB disease during clinical rotations in the hospitals. Therefore, screening for LTBI in this population represents hospital aspect of public health strategy and infection control in medical school in high TB burden countries. ObjectiveWe aimed to determine the prevalence of LTBI among fourth-year medical students and sixth-year medical students by using QuantiFERON-TB Gold Plus (QFT-Plus) and Tuberculin Skin Test (TST). MethodsA cross-sectional study of fourth-year medical students (n = 73) and sixth-year medical students (n = 85) was conducted at the School of Medicine, Chulalongkorn University, Bangkok, Thailand. The medical students (n = 158) who met the eligibility criteria were recruited into the study. LTBI was detected by using QFT-Plus and some of the participants had a tuberculin skin test (TST). The TST was interpreted after 48–72 h. The participants who tested positive by QFT-Plus were considered to have LTBI. Demographic information and data on occupational TB exposure were collected via a questionnaire. A multivariate logistic regression was used to test for associations between independent variables and results of the QFT-Plus. ResultsA total of 158 participants were included in this study. The overall prevalence of LTBI was 6.3% (n = 10) as determined by QFT-Plus. The LTBI prevalence was higher in the sixth-year medical students (9.4%) compared to the fourth-year medical students (2.7%). Higher risk of LTBI was associated with sixth-year medical students (odds ratio, 3.69 [95%CI, 0.75–17.96]), but this was not significant. Moreover, history of occupational TB exposure without PPE yielded an odds ratio of 2.98 [95%CI, 0.68–13.12] but it was not statistically significant due to the small sample size. One hundred thirty-nine (88%) participants were BCG vaccinated as per the national vaccination requirements. No abnormal chest X-rays were found for any of the positive participants. Of the 158 participants, 41 (25.9%) of them had TST. Of the 41 participants, 6 (14.6%) tested positive at a cut-off of ≥ 10 mm for TST, which was concordant with QFT-Plus results. The agreement between the two tests was 0.57 using kappa coefficients. ConclusionThe screening of TB infection in new healthcare workers (HCWs), especially medical students, is essential to reduce future nosocomial TB incidences in the hospitals. This study showed that there was a high prevalence of LTBI among sixth-year medical students compared to fourth-year medical students. Our results suggest that tendency of higher LTBI prevalence might be associated with advanced clinical years, thus tailored public health education strategy and infection control in tertiary care hospitals for new healthcare workers in TB endemic countries may prevent nosocomial TB disease from developing in the future. Therefore, active surveillance should be done for all new HCWs, and TB preventive therapy should be administered to recent converters.

Burden of TB during COVID-19 pandemic-single center experience.

To the Editor, COVID-19 pandemic has impacted tuberculosis (TB) diagnosis, surveillance and management due to lock down, hesitancy in visiting hospitals due to fear of contracting SARS-COV-2, healthcare workforce shortage due to over-helming cases and lab burdened with testing for SARS-COV-2.[1] We looked at the burden of TB during COVID-19 pandemic in our institution and specific risk factors for TB during this period. A retrospective observational study by electronic medical record review was done in a 750 bedded quaternary centre in Kerala, South India, between January 2020–2022. Number of cases reported through NIKSHAY, the web enabled patient management system for TB control under the National Tuberculosis Elimination Programme (NTEP), during this period were noted and compared with previous years’ hospital and national data. Clinical and radiological features, associated with COVID-19 infection and comorbidities were looked at. During the study period 293 cases of TB were newly diagnosed of which 117 were diagnosed in 2020 and 176 in 2021. The trend in cases notified revealed that there was >50% drop in cases during 2020 as compared to 2018 and 2019 [Figure 1]. The nadir in case numbers was between March and June 2020 which was similar to national data and was during the period of lockdown in the country.[2,3] The cases gradually increased during later part of 2020 and in 2021 [Figure 2]. Majority were men (62%); 6.14% belonged to paediatric age group. Extrapulmonary TB (EPTB) was noted in 63%. The common comorbidities noted were diabetes mellitus (64%), chronic kidney disease (28%) and systemic hypertension (28%). Fifteen patients (5.12%) had TB diagnosed either concurrently (1%) or within 4 weeks (4.09%) of COVID-19 infection. Twelve of these cases were microbiologically confirmed TB; 3 were probable TB of which 2 cases were diagnosed as pleural TB based on the pleural fluid analysis and 1 was diagnosed as lymph node TB by histopathology. Among the 15 patients, one half had pulmonary TB; among the EPTB, lymph node TB (28.3%) was the commonest. Among those with TB and recent COVID-19 infection, 72% had received steroids.Figure 1: Monthly data of newly detected TB cases in numbers over the yearsFigure 2: TB cases repoted to Nikshay before and during COVID pandemicTo summarize, the number of TB cases reported during COVID-19 pandemic was low and least during lockdown period and is similar to national data, suggesting that delay in approaching healthcare could be a reason. Majority of patients who had TB post COVID-19 had history of steroid use for COVID-19 infection suggesting that steroids could be a risk factor for opportunistic infections like TB. This is of importance as India is a TB endemic country. Steroid use for COVID 19 should be as per guidelines and those exposed to steroids and other immune suppression should be closely followed up for opportunistic infections such as TB. Enhancing TB surveillance by integrating TB and COVID-19 diagnosis by bi-directional testing as recommended by the Ministry of Health and Family Welfare in India is the need of the hour for early diagnosis of TB during pandemic.[4] Financial support and sponsorship Nil.

Comparison of Interferon Gamma Release Assay and Tuberculin Skin Test for Diagnosis of Latent Tuberculosis in Psoriasis Patients Planned for Systemic Therapy.

Background:Latent tuberculosis infection (LTBI) is a common yet difficult problem to diagnose in tuberculosis endemic countries. Both tuberculin skin test (TST) and interferon-gamma release assay (IGRA) are used for the diagnosis of LTBI.Aims:The aim of the study is to compare TST and IGRA in patients planned for systemic treatment of psoriasis.Methods:It was a diagnostic study conducted in a tertiary care centre during the study period from January 20 to December 20. Patients more than 18 years of age with chronic plaque psoriasis planned for systemic therapy were included. Psoriasis area severity index (PASI), history of tuberculosis in past or family and BCG vaccination were recorded. Complete blood count, radiograph of the chest, tuberculin skin test and interferon-gamma release assay were performed in all patients. Statistical analysis was performed using statistical package for social sciences (SPSS version 20, Chicago).Results:A total of 75 patients, including 48 males and 27 females, were included in the study. The mean age and mean duration of disease were 46.08 (±12.16) and 4.59 (±3.8) years, respectively. Seventy-one (94.6%) patients had BCG scar, and two (2.6%) had a history of tuberculosis in a family member. The TST and IGRA were positive (>10 mm) in 23 (30.6%) and 16 (21.3%) patients, respectively. Either TST or IGRA was positive in 28 (37.3%) patients. Out of these 28 patients, concordance was seen in 11 (39.2%) and discordance in 17 (60.7%). Discordance was TST+/IGRA − in 12 (42.8%) and TST−/IGRA + in five (17.8%) patients. Abnormality in radiograph of the chest and computed tomography (CT) scan of the chest were seen in five (6.6%) and nine (12%) patients, respectively. The patients with either TST or IGRA + were more likely to have abnormal chest radiographs than those who were TST−/IGRA− (OR: 11.3, 95% CI: 1.24–102.3, P = 0.03). The TST and IGRA showed fair agreement ( = 0.364, P = 0.003). ROC curve was plotted for the absolute value of TST in mm considering IGRA as the gold standard. The area under the curve was 0.805 (95%CI: 0.655–0.954). For the TST positivity cut-off of 10 and 15 mm, specificity was 77.3% and 95.5%, respectively; the sensitivity was 68.8% irrespective of the cut-off value.Limitation:Small sample size and lack of follow-up are the biggest limitations of the study. The lack of a gold standard in the diagnosis of LTBI is an inherent yet unavoidable flaw in the study.Conclusion:Reactivation of LTBI is a concern in a patient planned for immunosuppressive therapy. We suggest the use of both TST and IGRA rather than two-step testing (TST followed by IGRA) or IGRA alone for the diagnosis of LTBI, especially in patients with a high risk of reactivation. The positivity on either test should prompt further evaluation and treatment decisions should be taken considering the risk-benefit ratio of treatment rather than test results alone.

Prevalence, clinical profile, investigations, and visual outcome of sarcoid intermediate uveitis in a tertiary eye care center in South India

Purpose:To report the prevalence, clinical profile, investigations, and visual outcomes of sarcoid intermediate uveitis in a tertiary eye care center in South India.Methods: Retrospective, observational case series. Records of 29 patients with sarcoid intermediate uveitis were retrieved. Complete ophthalmic evaluation and systemic examination by a pulmonologist with appropriate laboratory investigations were done. Results were analyzed using SPSS software.Results: Mean age group was 42.14 ± 11.31 years. The bilateral presentation was more common and females were more affected than males. Anterior chamber cells and flares in 22.4% of cases (N = 11 eyes), posterior synechiae in 20.4% (N = 10 eyes), and both small and mutton fat keratic precipitates in 14.2% of cases (N = 7 eyes) were noted; only one eye had Busacca nodules similar to other granulomatous uveitis. Cystoid macular edemas were present in three eyes. Treatment with oral steroids and systemic immunosuppression resulted in good visual recovery. The mean presenting visual acuity in right and left eye were 0.2 and 0.3, respectively. The mean final visual acuity in right and left eye was 0.1 and 0.3, respectively.Conclusion: Sarcoid intermediate uveitis is quite common in a tuberculosis endemic country like India. A complete review of systems with appropriate investigations is essential to prevent visual complications.

Pericardial Disease and Pericardiocentesis in Adult Patients in Port Moresby General Hospital Papua New Guinea

Papua New Guinea (PNG) remains categorised as a Mycobacterium tuberculosis (MTB) endemic country [1]. Pericardiocentesis is recommended for patients with pericardial effusion in whom MTB is suspected, along with those with indications for therapeutics drainage [2]. This study aimed to report the incidence of TB pericardial effusion on GeneXpert [3] in patients living in Port Moresby.

Tuberculosis-Associated Erythema Nodosum

Erythema nodosum is panniculitis that is frequently observed in women aged 18 to 34 years. It usually occurs as an idiopathic condition; however, it may be associated with drugs, infections, malignancy, pregnancy, and systemic illnesses. Erythema nodosum presents with the sudden onset of tender, warm, erythematous nodules typically on the ankles, knees, and shins. Although the pathogenesis has not been fully elucidated, evidence supports a delayed type IV hypersensitivity reaction. It is often a clinical diagnosis that does not require a biopsy; appropriate work-up and careful medication history are crucial to identifying an underlying etiology if present. This report describes a woman from Vietnam, a tuberculosis endemic country, who presented with erythema nodosum that was determined to be a sequela of latent tuberculosis. Several studies have demonstrated an association between erythema nodosum and tuberculosis, especially in endemic regions. Summarized data reveals the incidence of tuberculosis-associated erythema nodosum to be six percent; however, when individuals with either secondary erythema nodosum or infection-associated erythema nodosum are evaluated, the incidence of tuberculosis-associated erythema nodosum is 11% or 21%, respectively. Evaluation of erythema nodosum should include a tuberculin or QuantiFERON test, chest roentgenogram, and/or an acid-fast bacilli sputum culture if the diagnosis of tuberculosis is being considered.

Curative lobectomy without a preoperative tissue diagnosis in a tuberculosis endemic country: A case report and discussion

Curative surgery for a localized tumour at the early and pre-symptomatic stage is the main aim of lung nodule assessment. As part of the process, pre-operative tissue diagnosis is a key step in making appropriate clinical decisions and avoiding unnecessary invasive surgical intervention which is associated with high morbidity. In this case report, we describe a patient who had a curative lobectomy for a growing nodule without a preoperative tissue diagnosis although the initial discussion deemed it mandatory, and we dissected the arguments supporting it in the setting of a tuberculosis endemic country.

Systemic corticosteroids for management of ‘long-COVID’: an evaluation after 3 months of treatment

Some patients even 4 weeks after Corona Virus Disease 2019 (COVID-19) remain to be symptomatic and are known as "long-COVID". In the present study we performed the follow up evaluation at 3 months of long-COVID patients, after treatment with systemic steroids. During the study duration, out of the 4,542 patients managed in the outpatient department of the particular unit, there were 49 patients of Long-COVID. The patients having abnormal computed tomography (CT) alongwith resting hypoxia or exertional desaturation were treated with systemic steroid (deflazacort) in tapering doses for 8-10 weeks. We retrospectively analysed the clinical and radiological findings of these patients at first presentation and at about 3 months of follow up visit. On follow up, all the 49 long-COVID patients showed improvement. The occurrence of breathlessness decreased from 91.83% to 44.89% (p<0.001) and cough from 77.55% to 8.16% (p<0.001). Twenty-four patients were prescribed systemic steroids. Out of these, nearly 58% patients had MMRC grade 4 breathlessness, which decreased to < 2 MMRC in about 86% of these patients. MMRC grade (median) decreased from 3 to 1 (p<0.001). Majority of patients who were tachypnoeic and hypoxic at rest (n=7) showed improvement (71%), post-treatment with corticosteroids. Occurrence of normal chest X-ray increased from 12% to 71% (p<0.001). All these patients had abnormal CT thorax initially, and post-treatment 25% had normal CT thorax. Hence, we conclude that systemic steroids are helpful in hastening recovery of select subset of long-COVID patients. Simultaneously, we should be cautious of immunosuppressive effects of steroids like tuberculosis reactivation, especially in tuberculosis endemic countries. These findings have therapeutic implications and may serve as guidance for future approach to the management of 'long-COVID' with pulmonary sequalae.

Association of Vitamin D Deficiency With Pulmonary Tuberculosis: A Systematic Review and Meta-Analysis.

Pulmonary tuberculosis, caused by Mycobacterium tuberculosis, is a significant public health issue, especially in developing countries, affecting millions of people every year. Despite the development of many antitubercular antibiotics and increased awareness of preventive methods, it is still a major cause of mortality worldwide. Vitamin D, a micronutrient known to have a major role in bone and calcium metabolism, has also shown its immunomodulatory effects to suppress mycobacterial growth. We conducted a systematic review and meta-analysis of the available evidence to explore the association between vitamin D levels and tuberculosis. We performed a systematic search for articles from inception to May 2021 in multiple databases. We included 26 studies in our qualitative synthesis and 12 studies in meta-analysis or quantitative synthesis. In our meta-analysis, we used a random-effect model to calculate the odds ratio (OR) of vitamin D deficiency in tuberculosis patients compared to the healthy controls. On pooled analysis, we found that the odds of the participants having vitamin D deficiency was 3.23 times more in tuberculosis patients compared to the healthy group (OR=3.23, CI = 1.91-5.45, p<0.0001). Thus, we concluded that there is an association between low levels of vitamin D and tuberculosis infections. We suggest conducting long-term prospective cohort studies in tuberculosis endemic countries to better understand the causal relationship between vitamin D deficiency and tuberculosis.

Miliary Tuberculosis with Severe Pneumonia without Abnormal Chest Sounds in a Covid-19 Pandemic

Background: Tuberculosis (TB) is still causing deaths in children in TB endemic countries. Majority (80%) occur in the lungs, with 5% being miliary TB. It is an Interstitial Lung Disease (ILD) with similar clinical, physiological and radiological features to other ILD and affects mainly infants and children with a high mortality rate despite available treatment. Case Presentation: A three-month old male presented during the COVID-19 pandemic with fever of 2 weeks, cough of one week, fast and difficult breathing of 6 days’ duration. He received BCG vaccine 16 days after birth despite being unknowingly exposed to the TB contact from birth. He was acutely ill looking, with severe pneumonia and SPO2 of 76% in room air. Respiratory examination showed broncho vesicular breath sounds with no added sounds. A diagnosis of Severe pneumonia? Pneumocystis Jiroveci Pneumonia (PJP) and R/O COVID-19 was made. Subsequent reviews excluded PJP and COVID-19 and the final diagnosis was Disseminated (Miliary) TB. He was successfully treated with anti-TB medications for 12 months. Conclusion: Miliary TB presents with common and uncommon manifestations that may be confusing, and so a high index of suspicion with a careful history, focused systemic examination, imaging and bacteriological studies are strongly recommended for its early diagnosis.

Impact of storage conditions on a new child-friendly dispersible tablet for treating Tuberculosis in pediatrics.

Background: In 2020 the composition and procedure to elaborate a new formulation containing Isoniazid, Pyrazinamide and Rifampicin to treat tuberculosis in pediatric patients was published. The temperature and relative humidity in Tuberculosis-endemic countries are high, &gt; 30ºC and &gt; 70% respectively and thus these meteorological conditions required a new dosage form. The objective of this work is to register changes in tablet quality and stability over time when exposed to different storage conditions according to ICH. Method: Tablets were subjected to accelerated, long term and low relative humidity conditions. The effect of light was also tested. Quality was measured by evaluating weight changes tensile strength, disintegration time, and drug content. Hydrazine formation was also evaluated as it is considered a mutagenic degradation product. Results: Tablets stored at low relative humidity showed the best stability. There was no statistically significant difference between tablets exposed to or protected from light. Moreover, the formation of Hydrazine was not detected during stability studies. Conclusion: This new dosage form for treating Tuberculosis is stable and able to maintain its quality when appropriate storage conditions are used.

Long-term Survival of Treated Tuberculosis Patients in Comparison to a General Population In South India: A Matched Cohort Study

ObjectivesThis study aimed to measure the mortality rate, potential years of life lost, and excess general mortality among individuals treated for pulmonary tuberculosis (TB) in a TB endemic country. MethodsA retrospective analysis was conducted on a population-based cohort study of 4022 TB patients and 12,243 gender-matched and age-matched controls from prevalence surveys conducted between 2000 and 2004 in the Thiruvallur district of Tamil Nadu, South India. ResultsThe mortality rate among TB patients was 59/1000 person-years. The excess standardized mortality ratio was 2.3 (95% CI: 1.7–3.1). The rate of potential years of life lost was 6.15/1000 (95% CI: 5.97–6.33) in the TB cohort compared to the general population of 1.52/1000 (95% CI: 1.46–1.60). Individuals aged >50 years, those underweight (<40 kg), with treatment failures, or lost to follow-up had higher mortality rates when compared with the rest of the TB cohort. The risk of death was significantly higher in the TB cohort until the end of the fourth year when compared with later years. ConclusionMortality in the TB cohort was 2.3 times higher than in the age-matched general population. Most deaths occurred in the first year after completing treatment. Post-treatment follow-ups and interventions for reducing comorbid conditions are necessary to prevent deaths.

Midfoot tuberculosis: Clinical suspicion and early investigation is the key

BackgroundTuberculosis affecting midfoot is not common, leading to delay in diagnosis further leading to deformity and difficult management. Tissue diagnosis is always not possible at such sites. MRI is the better imaging modality to diagnose earlier than conventional radiographs. The aim of the study is to have a clinical suspicion of tuberculosis in midfoot pain and a low threshold to perform MRI in these patients. MethodsThe data of 7 patients were collected prospectively over 3 years. Inclusion criteria included midfoot pain for more than 4 weeks in a skeletally mature patient with no radiographic findings. MRI and laboratory investigations were done in all the patients. All the patients were given Anti-tubercular therapy and followed up for 12 months. The patients were assessed at 3, 6- and 12-months duration with ESR, CRP, MRI, VAS and AOFAS Midfoot scores. ResultsThere were 3 males and 4 females included in the study with a mean age of 55.5 years. The mean duration of symptoms was 5.2 weeks. The mean ESR and CRP at presentation were 46 and 12 respectively which progressively decreased over 12 months. The mean VAS and AOFAS midfoot score at presentation were 4 and 70 respectively. None of the patients had any complication from ATT drugs. Residual pain was present in 4 patients with no functional limitation of the foot. The follow-up MRI showed healed tuberculosis in all the patients. ConclusionsTuberculosis can be a cause of vague midfoot pain in tuberculosis endemic countries. The MRI in such patients along with laboratory findings can lead to early diagnosis and the empirical institution of the ATT. The tissue diagnosis is not always possible in the early stages of the disease as there is no radiographic lesion or collection in the midfoot.

Tuberculosis cases comparison in developed country (Australia) and developing country (Indonesia): a comprehensive review from clinical, epidemiological, and microbiological aspects

Background: Tuberculosis (TB) is one of most crucial public health issues around the world. TB is an entity of a complex disease with the socio-economic aspect that has very strong correlation in regard to combat this disease. Migration from developing country to developed country inevitably possesses big influence on global epidemiologic of TB. In Australia, TB still becomes the main threat not only in native population but also regarding the migrant movement into Australia. Indonesia is one of among the TB endemic countries with high TB cases, in which not merely due to its high TB prevalence and incidence but also influenced by very high and dense population.Aim: This literature aims to review the clinical, epidemiological, and microbiological aspects of tuberculosis as a comparison between developed country (Australia) and developing country (Indonesia).Conclusion: Tuberculosis cases in Australia remains low compared to Indonesia, however, the close proximity to adjacent developing countries with high endemic of TB contributes significantly to increase number of TB in Australia. Tuberculosis can be cured by following the treatment guidelines with proper monitoring. Moreover, the collaboration between public and private sector along with active collaboration from the family or people surrounding the patients is required to eliminate TB disease.
