This was later resolved with the revision of the DSM-III, which aided many by providing appropriate treatment for patients. BDD was initially considered non-delusional in European research, and was grouped with ‘monosymptomatic hypochondriacal psychoses’ – delusional paranoia disorders, before being introduced in the DSM-III. In 1991, the demographics of individuals who experience BDD were primarily single women aged 19 or older. This statistic has not changed over the decades, women are still considered the predominant gender to experience BDD. With the rise of social media platforms, individuals are easily able to seek validation and openly compare their physical appearance to online influences, finding more flaws and defects in their own appearance. This leads to attempts to conceal the defect such as seeking out surgeons to resolve the issue of ugliness.Universally, it is evident that different cultures place much emphasis on correcting the human body aesthetic, and that this preoccupation with body image is not exclusive to just one society; one example is the binding of women’s feet in Chinese culture.Whilst physically editing the body is not unique to any one culture, research suggests that it is more common throughout Western society and is on the rise. On close observation of contemporary Western societies, there has been an increase in disorders such as Body dysmorphic disorder, arising from ideals around the aesthetic of the human body. Scholars such as Nancy Scheper-Hughes have suggested such demand placed upon Western bodies has been around since the beginning of the 19th century, and that it has been driven by sexuality.
The rash involves the palms or soles in as many as 80% of people. However, this distribution may not occur until later on in the course of the disease. As many as 15% of patients may never develop a rash. Complications
People can develop permanent disabilities including "cognitive deficits, ataxia, hemiparesis, blindness, deafness, or amputation following gangrene". Cause
Ticks are the natural hosts of the disease, serving as both reservoirs and vectors of R. rickettsii. Ticks transmit the bacteria primarily by their bites. Less commonly, infections may occur following exposure to crushed tick tissues, fluids, or tick feces. A female tick can transmit R. rickettsii to her eggs in a process called transovarial transmission. Ticks can also become infected with R. rickettsii while feeding on blood from the host in either the larval or nymphal stage. After the tick develops into the next stage, the R. rickettsii may be transmitted to the second host during the feeding process. Furthermore, male ticks may transfer R. rickettsii to female ticks through body fluids or spermatozoa during the mating process. These types of transmission represent how generations or life stages of infected ticks are maintained. Once infected, the tick can carry the pathogen for life.Rickettsiae are transmitted through saliva injected while a tick is feeding. Unlike Lyme disease and other tick-borne pathogens that require a prolonged attachment period to establish infection, a person can become infected with R. rickettsii in a feeding time as short as 2 hours.
