Headlines about COVID have faded, and the United States will soon turn the page on public emergency status for the pandemic. The virus no longer dominates most of our lives, yet there are still thousands of new hospitalizations daily and an estimated 15 million Americans currently suffer from Long COVID.

The deep impact of long-haul cases has contributed to a surge of patients with disabling conditions, who are often misdiagnosed or treated ineffectively. More than one in five people infected with COVID-19 develop Long COVID and its constellation of physical and neurological symptoms. The persistent pain, fatigue, sleep problems and brain fog are similar to two other post-infectious syndromes, fibromyalgia and chronic fatigue syndrome (CFS/ME).

A recent study of both conditions and Long COVID documented that the physical and cognitive impairments of Long COVID were exacerbated in people previously diagnosed with CFS/ME or fibromyalgia. These types of chronic overlapping pain conditions have long been recognized by the National Institutes of Health (NIH), and the president’s National Research Action Plan on Long COVID similarly makes the connection between CFS/ME and Long COVID.

More than 50 million people struggle with these neurological illnesses every year in our country, and the burden of their chronic diseases comes at incalculable personal harm, along with billions of dollars in healthcare costs and lost productivity. 

There is one common denominator among all these unrelenting illnesses: the human brain. Physicians like me who study infectious and neurological diseases know that getting a drug’s active ingredients into the brain is not easy. Unlike biologic drugs, which are usually administered by injection, the only medications that can cross from the bloodstream into the brain are small-molecule drugs.

But big pharmaceutical companies have largely abandoned the development of new small-molecule therapeutics, instead pursuing biologic drugs which tend to be more expensive and profitable. That is because of a complex mix of federal laws granting longer market exclusivity to biologics, patent law changes that remove economic incentives to develop new small-molecule therapeutics, and mounting Food and Drug Administration hurdles.

Yet small-molecule drugs can be highly effective and life-changing, as well as relatively cost-effective to manufacture and distribute. They are our best hope for offering real relief to people struck by cruel conditions rooted in brain function.

As we pick up the pieces from a once-in-a-generation pandemic, we cannot ignore the rise in debilitating post-infectious diseases. In a sense, the people afflicted by these illnesses are living with invisible scars from the infections that preceded their current illnesses. There is an urgent need to help them by restoring incentives for small-molecule drug development and streamlining regulatory processes for new treatments.

The government should be accelerating efforts to expand its support for new drug therapies to address fibromyalgia, CFS/ME, Long COVID, and other illnesses that originate in the brain. The untapped potential of emerging therapeutics is unacceptable, as is the fact that many patients’ symptoms are frequently misinterpreted or dismissed.

It is good news that the Advanced Research Project Agency for Health has been established within NIH to pursue biomedical breakthroughs. But our country could still be doing more on this front. Congress has the power to legislate a more level playing field for small-molecule drug development, correcting decades of bureaucratic bias.

Lawmakers should appropriate more resources to fast-track clinical trials and scale-up delivery of novel therapies for post-infectious diseases. Public-private partnerships could also go a long way towards bridging the gap between treatments that would transform patients’ lives and their current limited options.

We know from our experience with COVID that medical science is capable of swift and significant breakthroughs. Our public health system should be equipped to readily diagnose and effectively treat people with fibromyalgia, CFS/ME, Long COVID, and similar devastating illnesses.

While the symptoms of these diseases are often not visible, our responsibility to provide patients with advanced and effective care is very real. For millions of Americans and their families, the time for better treatments is now.
