Common coldAlso known as Cold and Upper respiratory tract infection (URTI)
Common cold is one of the most common ailments that every one of us might have had at some point in our lives. Although mostly caused by viruses, cold can also be triggered due to changes in weather or an underlying respiratory infection. It can spread by close contact with infected people or touching contaminated objects.
Sneezing, sore throat, feeling of being unwell, and nasal discharge are the most common symptoms associated with a cold. To diagnose a cold, assessing the physical symptoms is usually sufficient. In most cases, there is no need for any laboratory test.
Treatment of cold is mainly based on relieving the symptoms. Home care measures like steam inhalation, staying hydrated, gargling, use of nasal spray and taking adequate rest are effective in speedy recovery from the cold.

Poor hand hygiene
Exposure to contaminated objects
Chronic respiratory illness

Diagnosis Of Common Cold
The diagnosis of a cold is done on the basis of your medical history and physical examination. Usually, laboratory tests in case of a cold are of no or very little significance. However, there are some rapid tests suggested for the detection of influenza, parainfluenza, and adenovirus antigens in nasal secretions. Rhinovirus, influenza viruses, and adenoviruses are also detected by taking a throat swab.
Prevention Of Common Cold
You cannot always prevent a cold. However, by following some simple preventive tips, you can avoid catching a cold from other people.
Do not come in close contact with people who have a cold, particularly during the initial days of catching a cold as they are highly infectious around this time and may spread the infection.
Wash your hands frequently in a day, especially after coming in close contact with someone who has a cold or after touching an object which is contaminated. It is also important to wash your hands before and after meals.
Do not touch your eyes, nose, and mouth to avoid infecting yourself with the cold virus as your hands are the easiest way viruses and other infected particles enter your body.
Do not use personal belongings of an infected individual such as towels and handkerchiefs to avoid contracting the common cold.
Sometimes, a dry environment can also trigger a cold; therefore, keep a check on the humidity of your environment to prevent drying of sinuses.
If you have a cold, it is advised to cover your nose and mouth with a handkerchief or a tissue while coughing or sneezing.
Discard the used tissue in a closed lid bin and wash hands. It is also advised to stay away from vulnerable people suffering from asthma or other chronic lung diseases.

Cough that worsens while other cold symptoms improve

3. Pain relief medications

After this pour water (salt water solution) into your upper nostril and let the water flow or drain down towards the lower nose.
6. Sleep in elevated position
The sleeping position which is at a slightly elevated slope helps in better drainage of your mucus. You can keep pillows under your head to help fluids flow in your sinuses and prevent congestion.
Garging with salt water or povidone-iodine can help in reducing the incidence of upper respiratory tract infections.
8. Eat foods that support your immune system
Foods that are rich in Vitamin C and zinc helps you in recovering from the cold. Foods that are rich in Vitamin C such as oranges, lemon, bell peppers and strawberries can help you get relief from the symptoms of a cold.
9. Pay extra attention to hygiene
Keeping good hygiene will not only help in preventing cold but also helps in preventing the cold from spreading to other person. Make sure you keep your hands clean at all times and disinfect the frequently touched items/surfaces.
