Contact tracing is a process to identify people who are  at a high risk of developing TB due to their contact with a known TB case.

The aim of contact tracing is to find other people with TB disease and those infected with TB

All close contacts, especially household contacts of a Pulmonary TB patient, should be screened for TB. 

In paediatric TB patients, reverse contact tracing for the search of any active TB case in the child's household must be undertaken.

Particular attention should be paid to contacts with the highest susceptibility to TB infection.

Public Health Action is conducted under the NTEP programme to support and prevent further health complications among TB patients after diagnosis.

Tuberculosis and COVID-19 are infectious diseases which primarily attack the lungs. They present with similar symptoms of cough, fever and difficulty in breathing, although TB disease has a longer incubation period and a slower onset of disease.

The presence of tuberculosis disease during pregnancy, delivery, and postpartum is known to result in unfavourable outcomes for both pregnant women and their infants. These outcomes include a roughly two-fold increased risk of preterm birth, low birth weight, intrauterine growth restriction, and a six-fold increase in perinatal death.

Screen TB patients in Pregnancy & Lactating Patients

As a consequence of urbanization as well as social and economic development, there has been a rapidly growing epidemic of Diabetes Mellitus(DM). India has the second largest number of diabetic people in the world.

Several medical conditions are risk factors for TB and poor TB treatment outcomes. Similarly, TB can complicate the course of some diseases. Therefore, it is important to identify these comorbidities in people diagnosed with TB to ensure early diagnosis and improved outcomes. When these conditions are highly prevalent in the general population, they can significantly contribute to the TB burden. Consequently, reducing the prevalence of these conditions can help prevent TB.

Missed Dose recording in Nikshay:

For recording missed doses in Nikshay, following steps should be followed:

Manual recording of Adherence in Nikshay:

in Nikshay, Adherence can only be recorded only if there is corresponding dispensation being issued to a Patient 

Figure: Steps to record manual dose in Nikshay

Recording in Patient Treatment Card:

99DOTS is a low-cost digital adherence technology built-in Nikshay that uses inexpensive packaging(envelopes or stickers) with medication that enables people taking medication to engage with their treatment daily. This packaging, distributed to TB patients taking medications, has a hidden number behind perforated flaps on the external envelope; in some cases, the number may be fixed outside the medication blister or pill bottle. This number can be a toll-free number that can be called to register daily adherence or a code sent by SMS, USSD, or other communication channels.

Recording of Treatment Adherence can be done as

• Manually by DOT/Health Care Provider in TB Treatment Card of a patient.
• Self-reported by Patient using digital tools for reporting adherence using 99 DOTS and MERM technologies.

Monitoring Treatment Adherence:

All TB patients should be monitored to assess their response to TB treatment. Nikshay Adherence calendar has a colour legend for various doses taken by a patient
