Watch Out For These Types Of Common Colds

The common cold is an upper respiratory infection that causes symptoms that plague the nose and throat. Typically, most colds are harmless and you may only develop a few mild symptoms. Colds, more than anything, are very annoying and you just want to feel better to leave the sickness behind you. 

Common symptoms of a cold include runny or stuffy nose, sore throat, mild headache, sneezing, coughing, or low-grade fever. These symptoms usually last for about one week, but they can last longer in older adults, young children, or people with weakened immune systems. It is very common for adults to get two to three colds yearly, while children get them more frequently. 

It is very easy for a cold to spread. An infected person can sneeze or cough in your vicinity and you inhale microscopic droplets that contain the bacteria or virus. You can also touch a contaminated surface before touching your face and develop a cold that way. Given that there are over 200 viruses that can cause a cold, catching one is relatively easy. The rhinovirus is the most common, but  enteroviruses, human parainfluenza (HPIV), adenovirus, and coronavirus (the common cold version) can all cause common cold. Continue reading to learn more about the types of common colds. 

Enterovirus

Enteroviruses belong to a group of over 300 viruses, including echoviruses, polioviruses, coxsackieviruses, and rhinoviruses. These viruses can cause a range of illnesses, but the rhinovirus is the most common cold-causing virus. Other enteroviruses, including enterovirus D68 and coxsackievirus, can cause respiratory symptoms. There are non-respiratory enterovirus illnesses that can cause conditions such as hand, foot, and mouth disease, or aseptic meningitis. Common symptoms of enterovirus include cough, fever, runny nose, sore throat, wheezing, or pneumonia. 

Rhinovirus

Rhinoviruses account for about 50% of common cold cases. Although they can spread throughout the year, rhinoviruses are most active in the spring and early fall. They spread easily in crowded places, such as offices, schools, and public transportation. Symptoms, which can include cough, mild sore throat, sneezing, mild fever, or runny nose, tend to go away in seven to 10 days. Rhinoviruses can also cause other problems, such as ear infections, breathing issues, or sinus infections, especially in people with allergies or asthma. 

Adenovirus

Adenovirus can cause cold symptoms that last for longer than symptoms that result from the rhinovirus. In fact, some people can experience these symptoms for weeks, or months. This virus is more common in the early spring and winter, although it can occur year round. Common colds caused by the adenovirus can spread easily in hospitals, schools, daycares, and military barracks. Symptoms can include cough, runny nose, fever, and sore throat. That said, adenovirus is also known to cause conjunctivitis (pink eye) and bladder infections or diarrhea. 

Coronavirus (Common Cold Version)

Before anyone even knew about COVID-19, coronaviruses were a typical cause of common colds. In fact, coronaviruses account for nearly 15% of seasonal colds, usually peaking in the winter. Coronavirus colds are usually mild and tend to last for one week, but they can lead to more serious issues, including pneumonia, for people with weaker immune systems. The common cold coronavirus is different from the coronaviruses that cause COVID-19. If you have symptoms of COVID-19 virus, however, you can test for your own safety and the safety of others. Common symptoms of coronavirus colds include sneezing, runny nose, stomach problems (not too common), mild cough, and occasional low-grade fever.

Human Parainfluenza Virus

Human parainfluenza virus (HPIV) can cause infections in the upper and lower respiratory tract. That can affect airways in children under five years old, immunocompromised adults, and elderly people. There are four types of HPIV, with types one and two being the most common in fall. Type three occurs annually and is most common in spring and early summer, while type four tends to affect people year round. Symptoms of HPIV include fever, sore throat, stuffy or runny nose, cough, or chest pain, shortness of breath, and wheezing.

Determining which virus is behind your cold can be a little tricky, but certain patterns can clue you in to some degree. A barking cough usually indicates croup from HPIV, while a cold with pink eye comes from adenovirus. Your healthcare provider may want to run tests to detect the virus, depending on the severity of symptoms.
