Respiratory Tract Infection (RTI): Causes, Symptoms, and Home Remedies

Respiratory Tract Infection

Respiratory tract infection (RTI) affects both the lower and upper respiratory tract. However, upper respiratory tract infections are more common and include common cold (rhinitis), influenza, laryngitis (inflammation of voice box), pharyngitis (sore throat), sinusitis, tonsillitis, and croup (in children). Most respiratory tract infections go away without treatment, but sometimes you may need to see your doctor.

The Upper respiratory tract includes the nose, sinuses, pharynx, and larynx. The lower respiratory tract consists of the trachea (windpipe), bronchial tubes, the bronchioles, and the lungs.

Lower RTIs are more serious than the upper one, and these infections are the leading cause of death among all infectious diseases. Bronchitis and pneumonia are the two most common lower respiratory tract infections. Influenza affects both the lower and upper respiratory tracts.

Respiratory Tract Infection Causes

Over 200 known viruses can cause upper respiratory tract infections. These viruses spread very fast and are extremely contagious. They can infect the respiratory tract of any person by a direct contact like shaking hands, sharing food or drink, and kissing. They can also spread through coughing and sneezing.

The most common cause includes touching one’s eyes, nose, or mouth with own hands after touching the infected surfaces. Some of the acute pharyngitis cases may be caused by bacteria too. A sore throat caused by a bacterial infection is called strep throat.

Symptoms

Symptoms of upper respiratory infection usually include cold and cough, sore throat, runny nose, blocked nose, phlegm, headache, fever, facial pressure, earache, extreme sensitivity to cold and warm weather, and sneezing. The onset of the symptoms generally begins after 1-3 days of exposure to a virus.

The duration of the symptoms is typically 7 to 10 days but the infection may last for longer. As there are different types of respiratory tract infections, symptoms differ in all cases.
