Epidemic spreading on contact networks with adaptive weights

► We propose an epidemic SIS model on an adaptive and weighted contact network. ► Fixed weights setting can trigger the epidemic incidence. ► The adaptivity of weights cannot change the epidemic threshold but it can accelerate the disease decay. ► Strong adaptivity can suppress the epidemic globally to a low level, but cannot exterminate it. ► In contact patterns the frequency plays a more important role in epidemic spreading than the intensity.
