We haven't solved how to prevent the recurrence of shingles in people who've already had it once.
open
Global / Unspecified, Global
People who've had shingles once remain at risk of developing it again, and current prevention through vaccination isn't uniformly accessible or effective for every at-risk group. A more comprehensive prevention approach remains needed.

We don't have an effective, scalable way to detect gestational diabetes earlier in pregnancy in low-resource settings.
open
Global / Unspecified, Global
Standard gestational diabetes screening often happens later in pregnancy and can be logistically difficult to access in under-resourced areas, delaying diagnosis and management. Earlier, more accessible screening remains an unmet need.

We haven't found a way to fully explain why some people develop chronic post-surgical pain after routine operations.
open
Global / Unspecified, Global
A subset of patients develop long-lasting pain after surgeries that are usually uncomplicated for most people, and the biological reason for this difference isn't fully understood. Better prediction and prevention could reduce this often overlooked outcome.

We haven't solved how to prevent malnutrition-related anemia in pregnant women in food-insecure regions.
open
Global / Unspecified, Global
Anemia during pregnancy increases risks for both mother and baby, and it remains common in regions where access to iron-rich food and supplements is limited. Closing this nutritional gap remains an unresolved global health priority.

We can't yet fully explain why some patients develop chronic complications from Lyme disease despite early treatment.
open
Global / Unspecified, Global
Even when Lyme disease is caught and treated early, a portion of patients still develop lasting symptoms, and doctors don't fully understand why treatment doesn't fully resolve the illness in every case. Solving this could improve outcomes for a currently underserved group of patients.

We don't have an effective way to prevent the joint pain that sometimes follows chikungunya virus infection.
open
Global / Unspecified, Global
Chikungunya can cause joint pain that persists for months or even years after the initial infection has cleared, and current treatment options for this lingering symptom remain limited. A more effective long-term treatment remains needed.

We haven't found a reliable way to detect thyroid cancer early in populations without routine neck screening.
open
Global / Unspecified, Global
Thyroid cancer is often discovered incidentally rather than through routine screening, meaning some cases are caught later than they could be with more proactive detection. Expanding accessible screening remains an underused opportunity.

We can't yet fully prevent the chronic cough that sometimes persists long after a respiratory infection clears.
open
Global / Unspecified, Global
Some patients continue coughing for weeks or months after the original infection has resolved, and treatment for this lingering symptom remains inconsistent. A clearer understanding of why this happens could improve treatment.
