Lower Respiratory Tract Infection Caused by Haemophilus Influenzae

Lower respiratory tract infection caused by Haemophilus influenzae (H. influenzae) is an infection in the lungs that can lead to severe breathing problems. It can affect people of all ages, although it is most common in infants, young children and the elderly. It can cause a severe and potentially life-threatening illness.

Haemophilus influenzae is a type of bacteria which is usually found in the nose and throat. Most people carry the bacteria but it is usually harmless. If it does cause infection, it usually happens after the bacteria has moved down into the lungs, where it can multiply and cause inflammation.

Common symptoms of a lower respiratory tract infection caused by H. influenzae include a high fever, difficulty breathing, a cough with mucus, chest pain and a feeling of tightness in the chest. Antibiotics are the standard treatment, and prompt treatment can help to prevent serious complications, such as pneumonia or bronchitis.

Risk factors for a lower respiratory tract infection caused by H. influenzae include being young or old, a weakened immune system, smoking, or having other health conditions such as asthma or cystic fibrosis.

To help prevent an infection, it is recommended to:

• Wash your hands often and properly to help stop the spread of germs and viruses.
• Avoid close contact with people who are sick.
• Get vaccinated against H. influenzae.
• Avoid smoking or secondhand smoke.
