People with latent TB infection do not have symptoms, and they cannot spread TB bacteria to others. However, if latent TB bacteria become active in the body.
The success of treatment relies heavily on health care provider compliance, ensuring the right treatment is prescribed i.
Health care provider compliance and patient adherence are important to prevent the development of drug resistance and relapse. The disease does not always confer protective immunity as reinfection can occur.

Almost everyone is susceptible to infection, however some groups are more susceptible to infection and progression to active TB than others. Those at increased risk of infection due to clinical vulnerability include those with HIV infection and other forms of immuno-suppression. The risk of developing the disease once infected is high in the following groups of people 3: Aboriginal people and Torres Strait Islanders in some parts of Australia are at increased risk of TB due to adverse social and health factors.
These include overcrowding and high rates of chronic diseases that increase the risk of reactivation of TB and some that can confound the diagnosis of TB such as the presence of chronic lung disease. In there were 1, cases 6. Although rates of TB in Australia have remained low, specific subgroups such as Indigenous people and persons born overseas, still have rates many times those of non-Indigenous Australian-born persons.
Compared to the treatment of drug-sensitive disease, the treatment of MDR-TB and XDR-TB takes considerably longer up to 2 years or more to completerequires multiple drugs that are less potent and more toxic, and outcomes are poorer. Routine prevention activities TB Program activities The most effective means of preventing transmission of TB is early diagnosis and prompt effective treatment. Case management and contact screening undertaken by TB services are important public health measures in minimising transmission of infection and preventing emergence of drug resistance.
Border screening Pre migration Migrants, refugees, irregular maritime arrivals IMA and long-term visitors to Australia are screened for evidence of TB prior to being granted a visa.
Active TB is the only condition where automatic exclusion from entry into Australia is regulated.

To minimise the potential for transmission of TB within Australia extensive pre migration screening for TB is undertaken by the Department of Immigration and Citizenship. Post migration Post migration screening is carried out in conjunction with jurisdictional TB Prevention and Control Services.
Screening for LTBI is recommended in some groups e. It is only recommended for specific high-risk groups 10, 11 such as: Neonates born to parents with leprosy or a family history of leprosy.The TRUTH About Online Dating on ROBLOX
BCG vaccination may also be considered for: HCWs who may be at high risk of exposure to drug resistant TB. Surveillance objectives To identify and treat infectious cases of TB in a timely manner. To identify infected contacts and reduce their risk of developing active TB.
To monitor the epidemiology of TB in Australia to better inform prevention strategies.
To identify and monitor drug resistance. Data management All cases fulfilling the TB case definition are to be notified and data entered onto jurisdictional disease databases. Outcome data for cases needs to be updated by August 2 years following the end of the notification year. Enhanced data are collected for each notified case of TB, which includes risk factor information, clinical diagnostics and treatment outcomes. Data are reported to WHO by the May following the end of the reporting year, acknowledging that data is preliminary at this point in time.
Communications Once a TB case is known to public health or TB services, there are situations when Communicable Disease Directors or their nominated delegate of the relevant jurisdiction should be immediately notified. Further reporting of cases and need for contact tracing within or between jurisdictions is made by the jurisdictional TB staff of the index case, on a case by case basis, in accordance with jurisdictional protocols.
Communicable Disease Directors or their nominated delegate are informed of cross border actions.
Case definition Confirmed cases of TB, which include clinically diagnosed TB, should be notified as a legislative requirement. The case definition of a confirmed case can be found at the Department of Health and Ageing Case Definitions web page: Laboratory testing Testing guidelines Laboratory testing for TB is indicated in people with a clinically compatible illness, particularly if they are at increased risk of TB.
Sputum should be collected as early-morning samples on 3 separate days for highest sensitivity. Sputum induction using nebulised hypertonic saline or gastric lavage may be attempted in appropriate patients unable to expectorate.
Sputum collection from patients at high-risk of having TB should be performed in negative-pressure ventilation rooms.
Sputum collection from low-risk patients should be performed in well-ventilated areas away from other patients. In settings where patients at high risk of or with known infectious TB require cough-inducing procedures HCWs should wear respiratory protection i. Materials and Methods In order to extract current trends in diagnosis and medical or surgical treatment of spinal TB we performed a narrative review with analysis of all the articles available to us published between the years and The reports about different aspects of spinal TB, with acceptable design, clearly explained results and justified conclusions according to the data were included in this review.
Since, one of the aims of this review was to discuss the historical aspects of TB management we included articles regardless of their time of publication. Pathophysiology There are two distinct types of spinal TB, the classic form or spondylodiscitis, and an increasingly common atypical form which is spondylitis without disc involvement [ 6 ].
In adults, the involvement of the intervertebral disc is secondary to spread from adjacent infected vertebra whereas in children it can be primarily due to the vascularized nature of the intervertebral disc. The basic lesion in Pott's disease is a combination of osteomyelitis and arthritis, usually affecting more than one vertebra. The anterior aspect of the vertebral body adjacent to the subchondral plate is commonly involved [ 7 ].
Spinal TB can include any of the following: Diagnosis Differentiating spinal TB from pyogenic and fungal vertebral osteomyelitis as well as primary and metastatic spinal tumors may be difficult when only clinical and radiographic findings are considered [ 8 ]. A history of tuberculosis, a positive skin test its value declines in endemic areasand an elevated erythrocyte sedimentation rate ESR may be useful in the diagnosis of spinal TB [ 89 ]. Biopsy plays a valuable role in the diagnosis of spinal TB infection.
The use of DNA amplification techniques polymerase chain reaction or PCR may facilitate rapid and accurate diagnosis of the disease [ 10 ]. Culturing the organisms is slow and may be inaccurate. Nevertheless, it is still a precious diagnostic method in order to recognize the causative germs.
In a small number of cases with imaging and clinical findings suggestive of spinal infection, no organism can be cultured despite multiple attempts. Mycobacterial infection as well as fungal involvement should be considered in these cases. Computed tomography CT provides bony detail, while MRI evaluates the involvement of soft tissue and abscess formation.
The relative preservation of the disc, rarefaction of the vertebral endplates, anterior wedging, the presence of separate pre- and paravertebral or intra-osseous abscesses with a subligamentous extension and breaching of the epidural space, concentric collapse of vertebral body, ivory vertebra which is seen at conventional radiographs and refers to an increase in opacity of a vertebral body while preserving its size and contours with no change in the opacity and size of adjacent intervertebral discsneural arch tuberculosis, circumferential or pan vertebral involvement, extradural tuberculoma, subdural granuloma, intramedullary tuberculoma, and multilevel spinal TB are considered as the diagnostic clues for this disease in various imaging modalities [ 8911 - 14 ].
