At the time of wheat harvest, the weather is dry and the breeze caresses. This time of year there is a mold that begins to flutter in the air in large numbers, and that is Streptomyces interrogans. Streptomyces interrogans is an outdoor mold that multiplies in the soil and is commonly found on crops, leaves and lawns. It likes wheat, a grassy grain, and as the stalks turn yellow and dry, it also becomes dry and breaks up into countless small fragments floating in the air when the wheat is harvested, which can drift far away with the wind. Most people don’t notice it visibly, but a few people start to have itchy noses, continuous sneezing, clear watery nose, and in some cases, chest tightness, coughing, and wheezing. It was like this every year in June. They are very strange, thinking it is a cold or flu, and they are very careful, but they still can’t avoid it, but they don’t know it is the cause of allergy. There can also be cross-streptospore mold indoors because it will enter the room with the wind through an open window and multiply indoors. Therefore, some people with cross-streptomycosis allergy have symptoms all year round. Streptomyces interrogans is a representative of allergenic molds and is one of the most common allergenic molds worldwide. The mold is widespread in nature and its spores and mycelium floating in the air can cause allergies. The reason why only a few people are allergic is because the occurrence of allergic diseases is related to the body type. The immune system of the allergic person’s body overreacts to substances normally present in the environment and is overly sensitive (not hypo). The condition can be lifelong, so it is important to live with it and take appropriate protective measures and medication when necessary, etc. So, how to avoid mold? For those who are allergic to mold, musty carpets, clothes, books, etc. should be taken away as soon as possible; trash cans should be cleaned in time; defrost the refrigerator often, clean and keep it dry; keep the room dry; try not to put potted plants indoors and on the balcony, because a lot of mold can grow in the soil; avoid using carpets and upholstery, especially in dark and damp basements, etc.; avoid indoor swimming pools, greenhouse flower houses and places with more dead grass Avoid damp rooms; do not use humidifiers; indoor dust contains a lot of mold, so you can take the same measures to prevent indoor dust allergy. When going out, avoid places where mold can easily breed, such as leaf piles, tree trunks near the ground, shady or grassy places and places where garbage is piled up. Wear a mask when you go out at the peak of mold season. The best treatment for allergy-induced diseases is the “four-in-one” treatment plan, i.e. allergen avoidance, patient education, medication, and desensitization. Allergen avoidance is the foundation. Proper medication can stop the disease and control the symptoms. Desensitization treatment is the root of the problem and is applicable to cases where allergens cannot be completely avoided. It provides specific immunotherapy against allergens, which can improve the immune status of the body, gradually become non-allergic to allergens, achieve long-term treatment and prevention, and reduce symptoms or even cure.
