Fig: insects stings
insects that are members of the hymenoptera family, such as honey bees, wasps, hornets, ants, etc.
, commonly cause allergic reactions. Some of these insects have very harmful venom too. The area around the sting shows redness, swelling, pain and itching. Most of the time, these reactions occur only a few hours, except in some cases. In certain cases, insect stings can be life-threatening to some people. Such reactions are called anaphylaxis. Anaphylaxis includes severe symptoms such as itching and hives all over the body, swelling of throat and tongue, dizziness, headache, cramps, nausea and vomiting, shock, loss of consciousness and in the worst case, death.
What about mold and asthma?
Fungal sensitization is a potential risk factor for allergic rhinitis and asthma and may contribute to the development of acute respiratory
issues
[ 23 , 24 ]. The prevalence of fungal allergies is estimated to be 3–10% worldwide [ 25 , 26 ].
Prominent allergenic fungi have been reported to provoke allergic responses in 19–45% of allergic patients and 80% of asthmatic patients from skin tests [ 27 , 28 , 29 ] and increase the duration of asthmatic symptoms [ 30 ]. Atopic workers regularly exposed to fungus and mold spores experience frequent rhinitis and asthma symptoms [ 31 ].
Can you have an allergy to indoor and outdoor mold?
More than 14 million americans suffer from allergies and the number continues to increase. Allergies are typically the result of family history and/or exposure to allergens. Allergens are the substances that produce an allergic response. Allergies are developed upon repeated exposure to environmental allergens. Allergies may be caused by food, indoor allergens and outdoor allergens. Year-round allergic reactions include foods, animal dander (cats, dogs, horses, and other pets, wool and feathers), cosmetics and house dust. Early springtime hay fever is most often caused by tree pollens. Late springtime pollens come from grasses and weeds. Ragweed begins in late august and continues until october or the first frost.
Of all airborne allergens that we breathe in outdoors, pollens and mould spores are the most common and problematic. Typical hay fever symptoms are a runny nose, itchy and watery eyes, sneezing, and a feeling of nasal congestion.
one of the most common triggers for seasonal allergies are pollen. They are small, light and dry, so the wind can carry them. Pollen counts can vary day-to-day, depending on several factors, including the weather. For example, dry, windy weather spreads pollen quickly. However, heavy rains and humid weather conditions weigh down pollen, keeping it on the ground. In general, plants and trees that pollinate via wind cause the most problems for people with seasonal allergies. Grass pollen: there are hundreds of different grass types. However, only some cause allergies. The most common types of grasses that cause allergies include rye, bermuda, johnson, kentucky, orchard, sweet vernal, bahia and timothy.
The signs and symptoms of a mould allergy can start abruptly upon exposure or have mild symptoms that linger with prolonged exposure. Mould allergy symptoms resemble that of other types ofupper respiratory conditions and allergies. They include: coughing, sneezing dry, scaly skin rash, irritated skin exposure to mould, even briefly, can cause a common symptom called mould rash, which is a similar skin condition seen in other forms of allergic reactions. The symptoms of mould rash include raw and sensitive skin, discoloration, itchiness, raised bumps, or dryness. Physical contact or inhalation of mould spores can trigger this rash. When it comes to indoor mould allergy symptoms, some people can have adverse reactions that grow in severity throughout the day (especially when exposed for long periods of time).
