Explaining common cold's to people is actually very simply. The reason for that is that everyone has experienced a common cold before, and and everyone knows the symptoms very well. Symptoms like sore throat, nasal congestion, and coughing are easily explainable. When it comes to the science most people know that there isn't a cure for the common cold because every year we catch cold's several times. The idea here is that there isn't one treatable cause for the common cold, they are hundreds of causes which why it is such a pesky thing to deal with. All of my sources on the common cold are reliable because they are backed by research. Some of my sources are also government funded.
The common cold affects society in it that everyone gets one. Because of the common cold we call out sick at work, don't go to school, and even make ourselves a burden to those around us. People with weaker immune systems and children are the most prone to catching colds. Because of this we often spend a lot of time showing our children how to be sanitary. It's even possible to say that the common cold fostered this whole culture of always wash your hands after you do something with them. We build our lives in such a way that we try to avoid getting a cold as much as possible. The common cold has helped us develop as a cleanly society. Some people might say that the common cold causes us to waste time but it's because of the common cold that we have such as thing like sick days. Everyone has called out of work sick before without actually being sick. Imagine not having that chance because common colds didn't exist. In the future I think we will most likely get even cleaner as a society to eventually eradicate the common cold.
I think the common cold has made me into a paranoid person. Anytime I see someone coughing or sneezing I try to avoid them more because I don't want to catch a cold. It makes me alienate people. At the same time I do value the fact that the common cold has helped society develop. We have things like antibacterial soap and spray because of the common cold. The whole "it destroys 99.9% of all germs" things is a way to assure people that these products will protect against the cold. Yes to me the common cold culture has helped society develop new products and solutions as well as push us further to that 100% of all germs standard
