A lower respiratory tract infection refers to an infection that affects the lungs and airways below the voice box. The most common lower respiratory tract infections include pneumonia and bronchitis.
Meaning: Lower respiratory tract infections are caused by various infectious agents such as bacteria, viruses, and fungi. These infections can lead to inflammation and infection in the airways and lung tissue.
Cause: Lower respiratory tract infections can be caused by different pathogens. Bacterial infections are commonly caused by Streptococcus pneumoniae, Haemophilus influenzae, and Mycoplasma pneumoniae. Viral infections are often caused by influenza viruses, respiratory syncytial virus (RSV), and rhinoviruses. Fungal infections are less common but can be caused by organisms like Aspergillus or Pneumocystis jirovecii.
Mode of transmission: Lower respiratory tract infections can be transmitted through respiratory droplets when an infected person coughs or sneezes. They can also be contracted by touching contaminated surfaces and then touching the face or mouth.
Major signs and symptoms: The signs and symptoms of lower respiratory tract infections can vary depending on the specific infection, but common symptoms include cough (with or without phlegm), chest pain, shortness of breath, fever, fatigue, and difficulty breathing. In severe cases, there may be bluish discoloration of the lips or nails due to lack of oxygen.
Treatment: Treatment for lower respiratory tract infections depends on the cause and severity of the infection. Bacterial infections are typically treated with antibiotics, while viral infections are managed with supportive care such as rest, fluids, and over-the-counter medications to relieve symptoms. In some cases, antiviral medications may be prescribed. Severe cases may require hospitalization and additional treatments like oxygen therapy or respiratory support. It is important to consult a healthcare professional for an accurate diagnosis and appropriate treatment.
