“…The role of Cimex lectularius as a vector for blood‐borne pathogen transmission continues to be investigated. Controlled scientific studies have demonstrated in vivo incubation of organisms carrying approximately 20 different human illnesses, including leishmaniasis, American trypanosomiasis, rickettsia, pasturella, tularemia, yersina, Q fever, plaque, relapsing fever, leprosy, oriental sore, and brucellosis (10,49–53). To date, no substantial evidence of transmission of these organisms from bedbugs to humans has been recorded (4,15,54).…”

The incidence of skin disease secondary to infestation with the human bedbug, Cimex lectularius, has increased dramatically in the United States and in the United Kingdom. We describe a child with a recurrent pruritic eruption of urticarial, erythematous papules on the face, neck, and extremities. The etiology of her cutaneous lesions was discovered to be a bedbug infestation in the home. The epidemiology, entomology, presentation, and treatment of bedbugs and their bites are discussed.

“…Those authors concluded that C. hemipterus would have a minor role, if any, in the transmission of T. cruzi in the domestic environment. In Argentina, C. lectularius bed bugs fed on wild-infected rodents were capable of transmitting T. cruzi and at an efficiency equivalent to that of triatomine bugs (159,160). In those studies, T. cruzi was found to persist for more than 320 days in the bed bugs, and the complete developmental stages in the gut were observed via microscopy.…”

SUMMARY Since the late 1990s, bed bugs of the species Cimex lectularius and Cimex hemipterus have undergone a worldwide resurgence. These bed bugs are blood-sucking insects that readily bite humans. Cutaneous reactions may occur and can start out as small macular lesions that can develop into distinctive wheals of around 5 cm in diameter, which are accompanied by intense itching. Occasionally, bullous eruptions may result. If bed bugs are numerous, the patient can present with widespread urticaria or eythematous rashes. Often, bites occur in lines along the limbs. Over 40 pathogens have been detected in bed bugs, but there is no definitive evidence that they transmit any disease-causing organisms to humans. Anemia may result when bed bugs are numerous, and their allergens can trigger asthmatic reactions. The misuse of chemicals and other technologies for controlling bed bugs has the potential to have a deleterious impact on human health, while the insect itself can be the cause of significant psychological trauma. The control of bed bugs is challenging and should encompass a multidisciplinary approach utilizing nonchemical means of control and the judicious use of insecticides. For accommodation providers, risk management procedures should be implemented to reduce the potential of bed bug infestations.

“…In 1912, just 3 years after Carlos Chagas described the transmission of T. cruzi by triatomines, Brumpt20 claimed to have infected almost all of 100 bed bugs exposed to an infectious mouse and subsequently, two mice through exposure to bed bugs. Several decades later, an Argentine group replicated the experimental transmission of T. cruzi between mice and bed bugs 21,22. These reports, written in French and Spanish, respectively, have been overlooked during the recent re-emergence of bed bugs.…”

“…Jörg22 relates that, in 1938, Salvador Mazza isolated the parasite from 4% of bed bugs and 40% of triatomines captured in the city of Jujuy. Such reports must be interpreted cautiously, given recent confusion over T. cruzi in wild-caught Mexican “bed bugs” that were, in fact, triatomines 23.…”

“…Such reports must be interpreted cautiously, given recent confusion over T. cruzi in wild-caught Mexican “bed bugs” that were, in fact, triatomines 23. However, in its original Spanish, the article by Jörg22 clearly distinguishes between bed bugs (“chinches”) and triatomines ( T. infestans or “vinchucas”) 22. Still, the report is only secondhand22; systematic analysis of bed bug populations in areas of T. cruzi endemicity will be needed to determine if they do commonly carry the parasite.…”

Populations of the common bed bug, Cimex lectularius, have recently undergone explosive growth. Bed bugs share many important traits with triatomine insects, but it remains unclear whether these similarities include the ability to transmit Trypanosoma cruzi, the etiologic agent of Chagas disease. Here, we show efficient and bidirectional transmission of T. cruzi between hosts and bed bugs in a laboratory environment. Most bed bugs that fed on experimentally infected mice acquired the parasite. A majority of previously uninfected mice became infected after a period of cohabitation with exposed bed bugs. T. cruzi was also transmitted to mice after the feces of infected bed bugs were applied directly to broken host skin. Quantitative bed bug defecation measures were similar to those of important triatomine vectors. Our findings suggest that the common bed bug may be a competent vector of T. cruzi and could pose a risk for vector-borne transmission of Chagas disease.
