1. Allergy

   An allergy is a hypersensitivity disorder of the immune system. Allergic reactions occur when a person's immune system reacts to normally harmless substances in the environment. A substance that causes a reaction is called an allergen. These reactions are acquired, predictable, and rapid. Allergy is one of four forms of hypersensitivity and is formally called type I hypersensitivity. Allergic reactions are distinctive because of excessive activation of certain white blood cells called mast cells and basophils by a type of antibody called Immunoglobulin E. This reaction results in an inflammatory response which can range from uncomfortable to dangerous. Mild allergies like hay fever are very common in the human population and cause symptoms such as red eyes, itchiness, and runny nose, eczema, hives, or an asthma attack. Allergies can play a major role in conditions such as asthma. In some people, severe allergies to environmental or dietary allergens or to medication may result in life-threatening reactions called anaphylaxis. Food allergies, and reactions to the venom of stinging insects such as wasps and bees are often associated with these severe reactions.

Examples of allergy in a Sentence

1. Donald Trump:

   We should be prepared for National Institute of Allergy. Is National Institute of Allergy going to be that much ? I hope not, and I think the more we push on the mitigation the less the likelihood National Institute of Allergy would be that number.

2. Ujwala Kaza:

   Everyone is a bit different, so treatment has to be tailored to the individual, in general, if there are any factors that are found to be triggers, the first step is to avoid those triggers. For example, if that adorable adopted cat who makes you sneeze sleeps on your pillow most nights, it may be a good idea to convince her to sleep in a different room. If you have a chronic postnasal drip from an allergy to pollen or from a deviated septum, its important to treat those issues as well.

3. Jerome Adams:

   That could be because the person doesn't have an infection at all and they just simply had allergy symptoms, it could be because they have a virus, and we know that cold is caused by a virus and doesn't benefit from an antibiotic. We know that COVID is caused by a virus – doesn't benefit from antibiotics. But what's interesting is that we're also finding out that there are bacterial infections – bacterial infections that don't benefit from antibiotics. Most ear infections actually, even when caused by a bacteria, studies show don't get better any quicker with an antibiotic than without an antibiotic.

   This seems pretty egregious. I can see how certain trainings or workshops that some parents take exception to seem really outside of what a history class can be expected to do, but the kind of texts that are being banned here make me feel that there is now just sort of an allergy to anything that mentions race or racism.

5. Tucker Carlson:

   PETA's discovered the National Institute of Allergy and Infectious Diseases spent more than 200 grand on a proposed experiment that would ‘ subject real male rhesus monkeys to feminizing hormone therapy to see whether that makes them more susceptible to HIV to help transgender women,' it couldn't get uglier.
