What characteristic increases the unnoticed transmission risk from nymphs causing RMSF?
Answer
Being the size of a poppy seed
A critical factor increasing the danger posed by nymphs of *Dermacentor andersoni* (and their potential to transmit pathogens like those causing RMSF) is their minute size. Nymphs are often described as being comparable in size to a poppy seed. This small dimension makes them extremely difficult to spot on skin or gear, which means they can attach, feed, and transmit disease for a longer duration before being noticed and removed, thus heightening the risk profile compared to larger, more visible adult ticks.
