What is c cold?

"Cold" usually refers to a common cold, which is a viral infection that affects the upper respiratory system. It is one of the most common illnesses in humans, and it can be caused by many different viruses, including rhinoviruses, coronaviruses, and influenza viruses.

Symptoms of a cold typically include runny or stuffy nose, sore throat, cough, congestion, and mild body aches. It is usually a self-limiting illness, meaning it will go away on its own without treatment in about 7-10 days. However, over-the-counter medications may help relieve symptoms.

People can reduce their risk of getting a cold by washing their hands regularly, avoiding close contact with sick people, and staying home when they are feeling unwell. While a cold is usually not serious, it can lead to complications in people with weakened immune systems, such as children, older adults, and those with chronic illnesses.
