In your childhood, you probably heard the phrase, "don't let the bed bugs bite." That saying originated from a real insect--the bed bug, or Cimex lectularius. Bed bugs get their name from the fact that they commonly make their homes in the beds of humans. Although they bite and feed on human blood, bed bugs do not transmit blood-borne diseases. However, they do pose other dangers to people.
Allergic Reaction
The Michigan Department of Community Health notes that the physical manifestations of bed bug bites can vary widely. You may not even notice bed bug bites at all. If you do notice bites, you may dismiss them as mosquito bites because the localized redness and swelling may look much like that the mosquito leaves behind. However, if you are sensitive to insect bites of any kind, you may experience an allergic reaction to bed bug bites. This allergic reaction can be mild, only causing itching, skin reddening and irritation. More severe allergic reactions are possible and may require you to treat them with anti-itch ointments or oral corticosteroids and antihistamines.
Infection
Bedbug bites alone do not cause infection. However, if you are unable to avoid scratching the bites, infection may result. Scratching bedbug bites can cause openings or breaks in the skin. Bacteria can enter through these breaks and begin to multiply, leading to infection. Your doctor can prescribe creams to apply directly to the bites to prevent infection or advise you to use over-the-counter antiseptic ointments instead.
Respiratory Problems
If you or a member of your household suffers from respiratory problems, the presence of bedbugs can worsen these conditions. Bed bugs shed their outer skins, or casings, as they grow. These casings, along with the bed bugs' feces, can dry out and become airborne. The Rhode Island Department of Health warns that breathing the cast-off material from bed bugs can aggravate asthma and other respiratory ailments.
Anemia
In an article published in the Canadian Medical Association Journal, M. Drs. Jane Pritchard and Stephen W. Hwang detail the case of a 60-year-old man who presented to his doctor with symptoms of iron-deficiency anemia. The patient had no physical causes of this anemia but upon examination of his home, the patient's doctor found an infestation of thousands of bed bugs. Pritchard and Hwang advise that certain people, including the elderly, infants and those who have certain pre-existing medical and mental conditions are more at risk for bed bug-bite induced anemia.
