Cold-Causes and Symptoms

A common cold is a viral infection that affects the nose and throat and is usually self-limiting. Most viruses initially show symptoms of a cold, such as a runny nose and itchy throat. One such example is COVID-19. Healthy adults catch colds at least a couple of times a year, but babies and toddlers catch colds more often. Common colds usually last for a week or up to 10 days for most people, and common colds most often do not require medical attention.

What are the symptoms of a cold?

Typical cold symptoms can occur 1-3 days after being exposed to the virus that causes the cold. Below are some of the signs and symptoms that may vary from person to person.

  • I have a runny nose
  • cough
  • sore throat
  • congestion
  • Body aches or mild headaches
  • sneeze
  • Low-grade fever

When you have a runny nose, the runny nose begins clearly and becomes darker yellow or green over time.

What is the cause of a cold?

Many types of viruses can cause colds, including human rhinovirus, coronavirus, parainfluenza virus, and adenovirus. The most common cause of a cold is a rhinovirus that can enter the body through the mouth, eyes, or nose. When someone is sick and coughs, sneezes, or talks, the virus spreads through droplets in the air. It can also be spread by touching or sharing the same object, such as a bowl or towel.

In general, a person can catch a cold at any time of the year because people tend to stay indoors during the winter and come into close contact with them.

Risk factor Of a cold

The factors that increase your chances of catching a cold are:

  • Year: Babies and toddlers have lower immunity than adults and are more likely to catch a cold.
  • Immune weakness: Chronic illness and weakened immunity increase the risk of catching a cold.
  • season: Both adults and children can catch a cold during the winter and rainy season.
  • smoking: Smokers are more likely to catch a cold.


Some common cold-related complications include:

  • Acute ear infection (otitis media): that It occurs when bacteria or viruses invade the space behind the eardrum.
  • asthma: Even if the individual does not have asthma, a common cold can cause wheezing, which can cause asthma.
  • Acute sinusitis: If the cold does not go away, it can cause swelling, pain, and sinus infections.

Other infections that can occur as a secondary infection after a cold include pneumonia, bronchiolitis in children, and streptococcal pharyngitis.

What is a cold home remedy?

Getting plenty of rest, drinking plenty of fluids, and eating a high-fiber diet can help relieve the symptoms of a cold. Other home care remedies are:

  1. A warm soup to relieve symptoms and stuffy nose.
  2. Gargle with salt water for sore throat
  3. Cough medicines and troches to relieve cough and sore throat

How can I prevent a cold?

Here are some precautions you can take to prevent the spread of the cold virus:

  1. Wash your hands regularly – Thorough washing of hands with soap and water for at least 20 seconds is essential to prevent the spread of the virus. If soap is not available, you can use an alcohol-based hand sanitizer. Do not wash your hands and avoid touching your nose, mouth and eyes.
  2. Disinfect all objects – Doorknobs, children’s toys, lamp switches, kitchen and bathroom countertops should be disinfected on a regular basis.
  3. Cover while coughing – Always use tissue when coughing or sneezing and dispose of immediately. Remember to wash your hands thoroughly after this. If there is no tissue, bend your elbows and sneeze or cough to wash your hands.
  4. Do not share personal belongings – Do not share drinking glasses or utensils with your family while you have a cold. Use disposable glass and dispose of it after use.
  5. Be careful – Strengthen your immune system by eating a balanced diet with regular exercise and good sleep.

Common colds usually cause mild discomfort, and the symptoms of the cold can be controlled with medication. If you do not see any improvement after 10 days, it is advisable to see a doctor immediately.
