of the most highly allergenic contaminants found indoors is house dust, often heavily
contaminated with the fecal pellets and skins of House Dust Mites. Estimates are
that dust mites may be a factor in 50 to 80 % of asthmatics, as well as in countless cases
of eczema, hay fever, and other allergic ailments. Common causes of allergy include
house dust mites, cat dander, cockroach droppings and grass pollen.
Are respiratory in
nature, usually not a rash. However, there are reports of a red rash around the
neck. The wheeze-inducing proteins are digestive juices from the mite gut and are
potent. An exposure to the mites in the first year of a infants life can trigger a
is no cure, only prevention. One must control the
levels of dust mites. Beds are a prime habitat, a typical mattress may have anywhere
from 100,000 to 10 million mites inside. Mites prefer warm, moist surroundings such
as the inside of a mattress when someone is on it. Their favorite food is dander
(human skin flakes), also, bedroom carpeting and household upholstery support high
mite populations. Dust mites, due to their very small size (250 to 300 microns in length)
and translucent bodies, are not visible to the unaided eye. For accurate
identification, one needs at least 10X magnification. Through a microscope, one will
see many oval-shaped mites scuttling around and over one another. There are eight
hairy legs, no eyes, no antennae, a mouthpart group in front of body (resembles a head)
and a tough, translucent shell, giving a "fearsome appearance".
Recommendations focus on "dust control". One must reduce the
concentrations of dust borne allergens in the living environment by controlling both
allergen production and the dust which serves to transport it.
