Common Cold: Causes, Symptoms And Its Treatment

There are certain viral infections, you can catch all year round, and among them are influenza and common cold. Although most people think that these are seasonal viruses that spread during cold weathers, but this is not true. Common Cold is a viral infection that attacks the upper respiratory tract, which includes your nose and throat. It is the most common of infections with mild effects over our health. Despite this— common cold results in most number of doctor visits, requires urgent care to control the transmission and in absenteeism from work or school. Researches have shown that in the United States only around 1 billion people are infected by colds every year, resulting in almost 22 million days of school absences per year. The common cold is the most common disease that results in most frequent visits to doctors which is estimated to be approximately 75-100 million doctor visits every year, the economic influence of more than $20 billion annually due to work loss. People who are infected by common cold tend to spend more time in enclosed environment which at time maximises the risk of exposure for others and even for them, because of the enclosed area the infectious virus keeps on growing and spreading.

What causes Common Cold?

Common cold is mostly spread through a number of viruses; almost more than 200 hundred viruses are known to cause common cold. However, the most common among these are “Rhinovirus,” which causes 10% to 40 % of colds and the “Coronaviruses,” from which 20 % of colds are caused. Also, there “Respiratory Syncytial Viruses,” which cause about 10% of common cold. If caused by various kinds rhinovirus, the protective layer of the nose and throat is attacked by the virus, which results in activating an immune system reaction causing sore throat, a congested nose and headaches; thus making it hard to breathe. If the air is dry due to weather conditions or other reasons, then the virus tends to spread more rapidly and gets lower resistance from our body’s immune system. This is because the dryness around the nasal area makes the virus to stick and hold to our nasal passages. The virus is spread in the form of tiny droplets in the air, that gets mixed in the air through a sick person’s sneeze, cough or through their runny nose.

Common cold is considered to be highly contagious as it transmits from person to person. There are chances that a sick person at home infects others around him. As the virus spreads in the air through sneezing and coughing, other people making contact with areas or objects contaminated by the cold germs are more likely to catch a common cold and get sick. It is not necessary that a person gets a cold because of getting wet in the cold weather or being exposed to cold, people with nasal or throat allergies can catch a common cold at any time. At times emotional stress or fatigue can also be a cause of common cold.

The initial symptoms of common cold: a scratchy throat, congested or runny nose, watery eyes, sneezing, coughing, mucus drainage and headaches; are known almost by everyone. However severe symptoms along with these such as high fever or cramps are also a sign of influenza or flu. Other symptoms may include decreased appetite and aggression due to headache.
