21 Health effects of bed bugs Bed bugs do not vector disease organisms. They may carry hepatitis B in their gut but no transmission known. What bacteria do they carry on their bodies? Secondary infection – cellulitis resulting from bed bug bites – has been documented.

22 Health effects of bed bugs Cause anemia in severe cases. Bites on skin are unpleasant, may scar, and can rarely result in systemic allergic reactions. Cause stress, anxiety, sleeplessness (10-20% of fatal accidents from fatigue) Large economic cost to sufferers, which exacerbates emotional issues.

23 Fear and anxiety The only way for a bed bug sufferer to know whether their infestation is eliminated is to WAIT to be bitten again. Anticipation of being bitten again causes anxiety and stress, and even the delusion that every itch is a bed bug bite. This may trigger delusory parasitosis and other psychological issues.
