Author’s Note: I wrote this research essay, about the common cold and viruses. This was also for science class as well as Language Arts.
Have you ever wondered why people get sick? There are many sicknesses, like the common cold which is very common throughout that world. “The common cold is just a viral infection disease (What a Common Cold is).” The average adult gets 2-3 colds a year. The cold is in your upper respiratory system. A common cold is usually harmless, although it may not feel that way. “If it's not a runny nose, sore throat and cough, it's the watery eyes, sneezing and congestion — or maybe all of the above (Common Cold).” Although the common cold can be spread to others, allergies cannot.
Allergies do not spread. They are not contagious because allergies are caused by an overactive immune system (Is it a common cold or allergies? ). Many people around the world have allergies.Suffering from allergies is not uncommon. There are some over the counter drugs you can take to help. The difference between allergies and colds is the common cold is caused by hundreds of different viruses, while allergies are just because of your immune system. ”Your risk of developing allergies is related to your parents' allergy history” (Is it a common cold or allergies? ). If your parents have allergies you are at a higher risk of developing allergies.
The cold is common all around the world. It is called the “common cold” because most everyone gets it. “The symptoms of the common cold are a cough, sore throat, runny nose, and a fever (What a Common Cold is)”. The average child catches a cold about 6-7 times a year compare to adults, who they catch the cold about 2-3 times a year. ”Children are the ones that get the cold the most, because we develop immunity to many cold viruses as we age, which is why children are more likely to have colds than adults” (How to Catch a Cold). The cold is an illness caused by a virus infection located in the nose. Colds also involve the sinuses, ears, and bronchial tubes.
Next, Allergen is also related to allergies. “Allergen is the substance that causes allergic response” (What is Allergen?). “Allergens are substances that, in some people, the immune system recognizes as "foreign" or "dangerous" but cause no response for most people” (What is Allergen?). Common allergens include bacteria and viruses, chemicals, dust, perfumes, and smoke (What is Allergen?).
Allergen causes allergies and allergies are very common and can be treated.
Lastly, viruses. ”A virus is a small infectious agent that can only replicate inside the cells of another organism” (What is a viruse?). Viruses infect all types of organisms, such as plants, bacteria, and animals. Viral infections in animals provoke the immune system, which usually eliminates the infection virus (What is a viruse?). Vaccines can also produce immune responses, which confer to the specific viral infection. Examples of human diseases caused by viruses are the common cold, influenza, and cold sores. Vaccinations are a cheap way and effective way of preventing viruses (What is a viruse?).
In conclusion, the common cold, allergen, viruses, and allergies are all tied together in some way. There are many things you can do to prevent these viruses and colds. You can wash your hands and go to the doctor to stay healthy. Take advantage of all the little things that you can do to help your body stay healthy.
