Although it is known that soft ticks
are the only vector for TBRF, no soft ticks
were found or trapped.
Once infected, these soft ticks
are infectious for life (2) and transmit the spirochete to sleeping humans quickly (possibly within 30 seconds) during short feeds (15-90 minutes) (1-3).
For tick collections visits to villagers' houses, animal and poultry shelters were done by daylight in localities favorable to the nocturnal feeding habits of the soft tick
vector, and people were randomly questioned regarding their geographic origin and the frequency of tick bites.

are covered by a leathery, highly folded skin, granulated in appearance.
Hard ticks have one nymphal stage, whereas soft ticks
may have more.
have a long life-span and can preserve the CCHF virus for long periods, potentially providing a persistent virus reservoir, for infection of the corresponding livestock and hard ticks in a region, and consequently, possible outbreaks of CCHF.
species may also undergo more than one nymphal molt before reaching the adult stage.
This spirochete is transmitted to humans by the soft tick
Ornithodoros hermsi, which usually is associated with the nests of chipmunks and other wild rodents (1).
The mattress will have a pillow top and feature a soft tick
construction designed by Bekaert on Belgium damask.
An engorged soft tick
was found in her bedroom, and removal of house siding revealed multiple rodent nests from which approximately 30 Ornithodaros hermsi ticks were recovered.
In the western, northwestern, and foothill regions of the Alborz Mountains, the Argasid soft tick
Ornithodoros tholozani is commonplace and accounts for [approximately equal to] 60% of TBRF cases attributed to Borrelia persica.
One live soft tick
(Ornithodoros hermsi), four chipmunks, one wood rat, and two deer mice were recovered.
