A never-before-seen response

COVID-19 brought diagnostic testing into the global spotlight.

In reaction to the pandemic, countries around the world poured tremendous resources into fortifying laboratory infrastructures. As individuals and entire economies worked to cope with the surreal new way of life, diagnostic testing served as an anchor to early transmission-prevention efforts. While the swift response by the healthcare community deserves every accolade, the successes of several key testing strategies and solutions stem from another outbreak which took the world by storm decades earlier.

"We are now engaged in another deadly episode in the historic battle of man versus microbe.These battles have shaped the course of human evolution and of history.
We have seen the face of our adversary, in this case a tiny virus."

- William A. Haseltine, 1985
(Spoken before U.S. Senate subcommittee on HIV/AIDS)


Lessons learned from a previous pandemic

From terminal diagnosis to manageable chronic condition—is HIV elimination next?

In 2020, nearly 700,000 people suffered HIV-related deaths and an estimated 1.5 million new people were infected.1 At a glance, these numbers highlight the considerable work still to be done to combat this burdensome disease. However, a broader lens reveals the considerable progress made on this front.

Today, access to testing and treatment enable people to live normal, healthy lives, but advancing to this point required significant learning, innovation, sacrifice and investment.





How our understanding evolved

The impact of infrastructure; the power of policy.

In 1981, HIV/AIDS first received global attention, sparking fear and stigma as it erupted into a global epidemic. Fortunately, calls to fund research resulted in the development of the first PCR test for the virus. Over time, policies and financial programs were implemented, helping to alter the course of transmission and treatment.

Turning to testing to stop transmission

As the world better understood the nature of HIV—including the way in which the virus spreads—the medical community began formulating strategies to fight back. For example, discovering that a late diagnosis was associated with increased morbidity, mortality, and healthcare costs led to targeted efforts to support timely diagnoses.2 Awareness initiatives showed asymptomatic and pre-symptomatic persons the importance of testing which helped further containment. However, this ramp up was not universally achieved, leaving the virus to spread disproportionally.

Still today, some regions of the world face an array of cultural and socioeconomic barriers to change. These include education to combat stigmas which deter people from getting tested, public policy changes required to fund infrastructure, and philanthropic partnerships which can improve access to testing, monitoring, and therapy.

The impact of innovation on infection management

The established impact of diagnostics, and the promise of new developments in prevention, drew interest (and subsequent funding) from governments, NGOs and philanthropic organizations. The influx of funds boosted the development of paradigm-shifting tools and treatments that helped stem the spread of disease.

HAART (Highly-Active Antiretroviral Therapy)

This medication regimen is designed to reduce HIV viral load, making it undetectable and thus untransmittable (U=U). This has extended life expectancy in HIV patients by an average of 15 years.3



Mutation tracking

The Global Surveillance Program was established in 1998 at the International AIDS Conference to monitor changes in the HIV-1 genomic sequence. This enabled continuous improvements to molecular tests to account for viral mutations.

Dual-target testing

The advent of multiplex testing allowed for accurate and more comprehensive coverage from a single patient sample, saving time and resources, reducing error, and informing the use of anti-retroviral therapy (ART).4



Improving accessibility and mobility from diagnosis to result

Advances in sample collection, like dried blood spot and plasma separation cards, enable sample transportation without refrigeration, bringing high-quality diagnostic and viral load monitoring capabilities to remote and resource-limited areas.

Addressing stigma, privacy and patient follow-up

Smartphone-based patient reporting tools are designed to streamline result delivery, improve education, and empower people living with HIV to remain adherent to treatment and engaged in care by helping to protect individual privacy, navigate the stigma of disease, and reduce patient loss to follow-up.5



PrEP (Pre-Exposure Prophylaxis)

PrEP is a highly effective therapeutic measure to prevent the transmission of HIV from both sexual activity (99% effective when used as prescribed) and injection drug use (74% effective when properly administered)—a major step forward in the effort to limit the spread of disease.6

Venturing toward a vaccine

Currently in phase 1 trials, the development of an HIV vaccine would provide a significant boost in global prevention and eradication efforts. Similar vaccine strategies may also help inform the development of vaccines for other challenging pathogens.7


The foundation of disease elimination

Charting a course for future success.

Worldwide efforts to combat HIV have shown the potential of the right policies and funding, together with disease-specific diagnostic and therapeutic innovations. Looking across the global landscape of disease, other burdensome pathogens are logical next targets for concerted eradication efforts. These include, but are not limited to:

While there remain financial, logistical, and scientific hurdles in the way of elimination, there exists optimism among experts regarding the future of eradication. The diagnostic infrastructures in place as a result of COVID-19 present a rare opportunity to transform the dynamic between human beings and infectious diseases.

What will be done with this gift has yet to be written.
