New study reveals testing paradox Now, a new modeling study provides a counterintuitive explanation revealing a testing paradox: even when the observed cases increase, the true numbers of STIs can decrease. A key point of the model is that it distinguishes between symptomatic and asymptomatic infections, allowing us to implement differential testing," explains Laura Mueller, one of the researchers leading the project. The findings of the study can be useful for developing policies to monitor the progression and containment of sexually transmitted infections.
