What is the common cold?
First, we need to understand there are many disease-causing bacteria, many of which undergo genetic changes over time. These genetic changes make them resistant as they have been developing for millions of years. At this moment, bacteria are starting to show signs of resistance to medicines we use, which is a great problem. That is why they will probably continue to be a constant, though non-deadly nuisance for us humans. The only solution would be to have all disease-causing organisms removed from the earth. Besides that, we simply cannot get rid of all of Earth’s bacteria. In fact, our normal digestion, for example, relies on Escherichia coli bacteria that live in our intestines. Without this bacterium, we would cease to exist. Other bacteria that break down things such as dead leaves, animals, trees, etc., are essential to return nutrients to the earth and keep our environment functional. Even things like hair or skin cells would quickly accumulate if there were no bacteria to quickly break them back down to their basic components. Therefore, preventing the cold is an insurmountable task.
When a person becomes infected, bacteria invade the cells and the result is a typical feeling of sickness. By the time when we feel sick, the bacteria has already invaded and won, at least temporarily. Our body’s resistance to the invasion involves the production of immune cells to fight the virus. Our organism needs time to battle and win. We use medicine, called antibiotics, to aid in this battle. We commonly use aspirin, sinus medicine, and other drugs that counteract some of the histaminic reactions – our body’s reactions produced in response to the invasion.
For now, the only solution would be preventing cold by immunization. Viruses cause most common colds, so we would all like to make a vaccine that would protect us against these viruses. It should work the same way as the vaccine that protects us from polioviruses. Unfortunately, cold viruses change their coat proteins rather quickly, which means that our immune systems trained to find one type of coat would not find the new. That is why vaccines are not particularly effective. This is why we still cannot find a cure for AIDS, since HIV virus has the same quality.
