Cough Against TB: HCW App
The Terms may be amended from time to time, with prior notice to App users, in which case, in order to continue using the App, you will be required to accept the revised Terms.
About Cough against TB HCW
The Cough against TB – HCW app is an AI-powered cough-sounds-based screening solution to assess the likelihood of pulmonary tuberculosis in individuals, for the early detection and treatment of tuberculosis (TB). This App is intended to be used by healthcare workers (HCW).
Who should use this App?
HCWs designated by the National TB Elimination Program (NTEP). The subjects can be the general population of India from 18–100 years of age, who are not on a TB treatment regimen. Informed consent from parents/ or guardians is required for the screening of subjects below 18 years of age.
Who should not use this App?
- Individuals other than the HCWs designated by the NTEP.
- Individuals below 7 years of age and above 100 years of age should not be screened.
The Use of this App
The HCW agrees that they will only use the App in good faith and will not provide false or misleading information about themselves, the subject, or their symptomatic and clinical status. The HCW agrees that they will not indulge in any act that may impair the performance or functionality of the App.
How to use the app
The app can be installed on any smartphone with the following minimum specifications:
- Android smartphone running OS version 5 and newer.
- iPhone running iOS 11 and newer.
- A working microphone on the smartphone.
- Internet connectivity on the smartphone.
The App authenticates the HCW using an OTP delivered on the registered mobile number via SMS.
Personal and symptomatic data of the subject needs to be entered, as per the instructions provided in the form. HCWs should refer to Annexure 1 and Annexure 2 for safety measures.
Before recording the cough sounds, please ensure the following for each subject:
- Record the sounds in a well-ventilated and noise-free area.
- Ensure that the subject is wearing a mask.
- Hold the smartphone at an arm’s length/3-feet distance from the subject’s face.
- Do not let the subject directly cough into the smartphone. Hold it across from the subject at a 90-degree angle.
- Do not connect any external audio input device, e.g., headphones, earphones, external mic.
Interpreting the results and taking action
The App processes the symptomatic data along with the cough audio and provides the results as follows (please refer to the Disclaimer section for more information about the results):
Likely to have pulmonary tuberculosis
Based on the automated inference, the individual’s chances of having pulmonary tuberculosis are high and they should consult a doctor and get tested to confirm the diagnosis.
Not likely to have pulmonary tuberculosis
Based on the automated inference, the individual’s chances of having pulmonary tuberculosis are low and they should consult a physician if symptoms continue.
- The AI model in the app was trained on data captured at the facility-level (healthcare facilities).
- The AI model has been trained on a data set containing subjects above 7 years of age and below 100 years of age. The model should not be used for individuals below 7 years of age or individuals above 100 years of age.
- The Cough against TB – HCW AI model achieved a sensitivity of 90% and specificity of 30% on test data.
- The sounds were recorded using smartphone microphones. No external attachments for audio input (e.g., for better clarity of audio signals) were used.
- Internet connectivity is required for the model to be able to interpret the cough sounds.
- For any issues related to the above, please email firstname.lastname@example.org.

Annexure 1: Disinfection of Smartphones
For all devices used for data collection, we shall follow the below recommendations, as issued by the Ministry of Health and Family Welfare (MoHFW).
- For electronics such as smartphones, tablets, touch screens, remote controls, and keyboards, remove visible contamination if present.
- Follow the manufacturer’s instructions for all cleaning and disinfection products.
- Use of wipeable covers for electronics.
- If no manufacturer guidance is available, consider the use of alcohol-based wipes or sprays containing at least 70% alcohol to disinfect touch screens. Dry surfaces thoroughly to avoid pooling of liquids.
2. Guidelines issued by leading smartphone manufacturers
- Before you begin, power down your device, remove any case or cover and unplug any accessories.
- Wipe the exterior surface of the phone with a soft, lint-free microfibre cloth.
- Manufacturers warn against applying liquid cleaning solutions directly on the phone as that may damage the device, particularly the oleo phobic coating which helps protect the display from fingerprint smudges.
- Liquids and water could even get into open spaces, particularly on devices that don’t have an IP rating, so you could end up damaging your phone.
- For disinfecting the phone, dampen the corner of your cleaning cloth with a small amount of distilled water or disinfectant.
- You can use a hypochlorous acid-based (50-80ppm) or alcohol-based (formulated with more than 70% ethanol or isopropyl alcohol) product and wipe the front and back of your phone gently without too much pressure.
- Avoid wiping the device excessively. Manufacturers also caution against using compressed air or applying spray bleaches or liquid solutions directly on the phone.
- These cleaning guidelines are meant for glass, ceramic and metal surfaces, not for soft accessories that are made from materials like plastic, rubber or leather.
- If you use cases or covers on your phone, it would be a good idea to disinfect them as well, since they tend to capture a lot of dirt and grime anyway over time.
Annexure 2: Safety Measures for HCWs
The following measures will be undertaken to prevent infection during data collection.
- Persons with the willingness and dedication to work in this situation will only be recruited with written informed consent.
- The staff will be trained by qualified trainers on infection prevention and control practices before joining duty to attend health facility.
- Infection prevention measures during data collection will be ensured, such as:
- Cough sound will be collected at a well-ventilated place and away from other people.
- Individuals will cough with a mask on their face and all the cough hygiene measures.
- Data collection devices will be disinfected as per the instruction of the manufacturer or as per Annexure 1.
- Staff will be allowed to work in health facilities for not more than 6 hours, and all precaution measures will be followed as per the IPC guidelines.
- Any staff that develops respiratory symptoms will be removed from their data collection duties.
Implementation of appropriate infection prevention and control (IPC) measures
IPC is a critical and integral part of data collection from patients, as per the guidelines of the Ministry of Health and Family Welfare (MoHFW).
Standard precautions will always be routinely applied, including hand hygiene, avoiding direct contact with patients’ respiratory secretions, standard precautions for safe waste management and cleaning and disinfection of equipment (including data collection devices).
Implementation of infection prevention and control measures for patients with suspected or confirmed nCoV infection as per the guidelines of the MoHFW.
