Why Can’t We Cure The Common Cold?

There are many different types of viruses that cause the common cold. In fact, over 200 different varieties of viruses can cause the symptoms of a cold. The most common viruses that cause colds are called rhinoviruses. Other virus types include coronavirus, parainfluenza, adenovirus, enterovirus, and respiratory syncytial virus. The “rhino” in rhinovirus is derived from the Greek for “nose.” Rhinovirus describes species that belongs to the enterovirus genus of the family Picornaviridae. Other enteroviruses belonging to Picornaviridae include poliovirus and Coxsackie A virus. Rhinovirus is one of the smallest types of virus, with a diameter of around 30 nanometers. Optimal growth of the virus is achieved at somewhere between 33 and 35 °C, which is the temperature range found in the human nose. Around 100 rhinoviruses have been identified, all of which differ according to the proteins presented on their surface. As the predominant cause of the common cold in humans, primary symptoms of this condition include runny nose, sore throat, cough, sneezing and congestion. These symptoms may be accompanied by headache, muscle ache, muscle weakness, malaise and loss of appetite. Children can suffer from as many as twelve colds a year and in the United States, with colds occurring more commonly between September and April. This may be attributed to the school year starting around September and to people spending more time inside and within closer proximity of each other during these months.
