What are the effects of common cold?

The common cold is a mild, self-limited viral infection of the nose and throat. It is usually caused by one of more than 200 different types of viruses, with rhinoviruses being the most common. The common cold is highly contagious and can spread from person to person through contact with respiratory droplets, such as coughing, sneezing, or talking. It can also be spread through contact with objects that have been contaminated with the virus, such as doorknobs, toys, or clothing.

The symptoms of the common cold typically appear within 2-3 days of exposure to the virus and can last for up to 2 weeks. Symptoms may include:

* Sneezing

* Congestion

* Runny nose

* Sore throat

* Hoarseness

* Dry cough

* Low-grade fever

* Headache

* Muscle aches

* Fatigue

In most cases, the common cold is not a serious illness and will resolve on its own within a few days. However, some people may be at risk for more severe complications, such as pneumonia, bronchitis, or ear infections. These complications are more common in young children, elderly adults, and people with weakened immune systems.

There is no cure for the common cold, but there are over-the-counter medications that can help relieve symptoms. These medications include:

* Decongestants

* Antihistamines

* Pain relievers such as ibuprofen and acetaminophen

* Throat lozenges and sprays

It is important to stay hydrated when you have a cold, as fluids can help loosen mucus and soothe a sore throat. It is also important to get plenty of rest.

If your symptoms are severe or do not improve after 10 days, it is important to see a doctor.
