Childhood TB

appChallenge TB has developed a simple mobile phone application that has begun to revolutionize the process of finding the missing childhood TB cases in Bangladesh.


The app (which is freely available for anyone to use) was tested in several health facilities and used to identify children with TB symptoms who are then taken aside for further testing. If you want to know the results, you can read the full story here.

Zero TB Cities

zeroDhaka, Bangladesh has become the latest city to sign up to the Zero TB Cities Initiative. The initiative will combine a public awareness campaign with TB screening, in order to help find many more of the “missing” TB cases.

A recent TB prevalence revealed very high rates of TB in the urban areas of Bangladesh, and Dhaka is estimated to have more than 150,000 missed TB cases every year.

As Dhaka is the fourth most densely-populated city in the world, controlling this airborne disease is critical to ending the TB epidemic in the country.

At the launch event, the US Ambassador to Bangladesh Marcia Bernicat praised the initiative, she said: “This is significant because Bangladesh has the seventh highest prevalence rate of TB in the world by bringing Dhaka into this initiative, we will be better able to prevent, identify and treat TB and help save lives.”

The initiative in Dhaka was launched with the support of USAID/Challenge TB.

In Memory of Dr. Bashir


In loving memory of Dr Bashir Popoola Zakariyya who died on the 17th of October 2017, aged 39.

You were the Regional Senior Manager Nasarawa for the Challenge TB Project, full of life and focussed on getting the best results. You always ensured there were no gaps in services, even when we were short staffed.

You are not here with us, but we have you in our hearts. At the start of every new working day, we picture you coming into the office and doing your rounds, greeting everyone and giving a smile as you passed by.

Your name is still mentioned as though you were still at your desk or somewhere in the office.

You are sorely missed, your impact was great, and your name will be mentioned a million times over.

Dr. Bashir Popoola Zakariyya, may your gentle soul rest in peace.

TB Stigma


The need for tools to measure stigma has been voiced before, only to be lost in the louder din of voices calling for new technologies, new medicines, and the rush to meet targets, deadlines, benchmarks and count up ‘cases’ that were ‘cured’. Past efforts to measure TB stigma have been stymied by doctrinal differences, internecine debates over definitions, and a pedantry that excluded many important stakeholders. Measuring TB stigma is not an elite project, but it does present some real technical challenges.

“Wellness On Wheels” the mobile truck equipped with digital X-ray and GeneXpert was launched today in Ogun State – Nigeria. The Challenge TB-financed truck and equipment, will offer free TB testing services in communities and provide rapid testing for suspected TB cases, meaning people who are infected can be placed on treatment as quickly as possible.

Nigeria has the 4th highest burden of TB in the world and the highest in Africa. With 600,000 cases annually and only 100,500 detected in 2016, around 83% of the cases were missed and are in the community infecting those around them. The new truck will take diagnostic facilities directly to the people, where it is hoped it will help to find these missing cases and begin to turn the tide of the disease in the country.

Botswana Laboratory Reopens


The only laboratory capable of cuture and drug susceptibility testing in Botswana was the National TB Reference Laboratory (NTRL), which until recently was mostly out of commission as the TB containment facility had not been functional for almost two years.

With technical support from Challenge TB, the Ministry of Health installed a new ventilation system and Challenge TB also financially supported the refurbishment of the NTRL containment facility.

The renovation was successfully completed in August 2016 and the laboratory became fully operational and resumed receiving and testing patient samples on the 1st September 2016. The laboratory was officially reopened by the US Ambassador to Botswana Mr Earl Miller and the Permanent Secretary of the Ministry of Health, Ms Shenaaz El-Halabi.
