Lower Respiratory Tract Infections (LRTI) Symptoms

In less-serious LRTIs, the symptoms are relatively mild and can be similar to the common cold. These include:

  • Congestion or runny nose
  • Dry cough
  • Sore throat
  • Low-grade fever
  • Mild headache

Mild LRTIs can sometimes become more severe, leading to pneumonia, bronchitis, or other more serious infections. At times one may have a viral infection that is then complicated by a bacterial infection. Symptoms of a more serious LRTI include:

  • Fever
  • Severe cough
  • Rapid breathing or difficulty breathing
  • Wheezing
  • Skin turning a blue color due to lack of oxygen
  • Chest pain or tightness
