The toll of COVID-19 has been much greater than the devastating number of deaths directly caused by the disease. Disruption of routine health services impacted efforts to eliminate diseases such as polio, hepatitis, and neglected tropical diseases (NTDs) like leprosy and river blindness. Years of community health campaigns have greatly reduced cases and improved lives for millions of people, with many diseases on track for elimination by 2030.

However, COVID-19 restrictions disrupted that work and, in April 2020, the World Health Organization (WHO) issued guidance to temporarily halt health campaigns. The COVID-19 Campaign Impact Tracker, hosted by our Health Campaign Effectiveness program, reported that more than a third of planned health campaigns were delayed worldwide in 2020, including those for polio and other immunizations, NTDs, and malaria, leaving people at risk of preventable diseases.

To help countries sustain progress, our teams equipped countries with tools to continue disease elimination activities while adhering to COVID-19 safety protocols. For example, our Coalition for Global Hepatitis Elimination (CGHE) developed guidance on how national hepatitis programs could safely continue testing and treatment. They also convened 44 countries to discuss the impact of COVID-19 on hepatitis care, highlighting that while the short-term effects have been negative, the pandemic response could strengthen health systems, boosting disease programs like hepatitis in the years to come.

Likewise, our Global Partnership for Zero Leprosy provided guidance on how to continue treatment, prevent greater transmission of leprosy, and reduce the risk of complications from COVID-19, as people affected by leprosy are a high-risk group due to immunosuppression.

As the WHO prepared guidance on resuming community NTD campaigns, our NTD Support Center worked with the WHO and partners on protocols to monitor the safety of resuming health campaigns and improve effectiveness while adhering to guidelines. Meanwhile, our NTD Supply Chain forum convened partners to resolve problems caused by interrupted drug production, shipment, and distribution, seeking to mitigate delays in delivery of treatment to avoid a resurgence of disease.

Many Task Force disease elimination efforts center on Africa which, in fact, had fewer COVID-19 deaths than other large continents in 2020. The BBC cited five reasons why: quick governmental action on public health measures; public support for safety measures; young population; favorable climate; and good community health systems. Indeed, the BBC noted that “the continent’s strength lay in its tried and tested community health systems.” Task Force NTD experts observed first-hand the effect of those systems.

“Sub-Saharan Africa was expected to have horrible COVID-19 results but they have strong health campaign channels in place informing people about other diseases like soil-transmitted helminths and trachoma. Health workers were able to use these channels to educate people about COVID. Because those programs were already strong, information about COVID protection was easier to share.”

As one example, while polio vaccination campaigns were temporarily paused in Ethiopia, our experts conducted COVID-19 case identification, contact tracing, and quarantine enforcement, and expanded the number of laboratory testing sites. 

While researchers assess the long-term impact of disruptions, Task Force teams continue to adapt and respond so communities can control, prevent and eliminate diseases.


Community health workers and organizations adapted to  pandemic guidelines in order to continue health campaigns that addressed other devastating diseases. One  example of this is the trachoma program in the island-nation of Nauru, the third smallest nation in the world, which conducted its first mass drug administration (MDA) for the elimination of trachoma during the COVID-19 pandemic.

In 2020, the MDA for the elimination of trachoma in Nauru was supposed to take place right as the COVID-19 pandemic began. Although it was slightly postponed, thanks to the island nation's swift action, they prevented COVID-19 reaching their shores and were able to proceed with trachoma elimination interventions.
The Task Force’s International Trachoma Initiative and partners shipped 14,448 trachoma treatments from Brussels to Nauru, a total of 12,451 miles. The number of teams scheduled to administer treatments was reduced because health staff were still working to prevent the spread of COVID-19. Despite the challenges and interruptions, the team found that educating community members about trachoma was also an opportunity to answer questions and provide information about COVID-19.
