Respiratory Infections

Viral respiratory infections are among the most common causes of illness, particularly during the colder months when people tend to spend more time indoors and in close contact with others. Influenza, caused by influenza viruses A and B, is a more severe respiratory illness that can lead to high fever, body aches, fatigue, cough, sore throat, and respiratory symptoms.

Bacterial respiratory infections, such as pneumonia and bronchitis, can occur as primary infections or as complications of viral respiratory illnesses. Pneumonia is an infection of the lungs that can be caused by various bacteria, including Streptococcus pneumoniae, Haemophilus influenzae, and Mycoplasma pneumoniae. Risk factors for respiratory infections include close contact with infected individuals, crowded living conditions, compromised immune function, and certain environmental factors such as air pollution and exposure to tobacco smoke.

Preventing respiratory infections involves practicing good hygiene habits, such as washing hands frequently with soap and water, avoiding close contact with sick individuals, covering coughs and sneezes, and staying home when sick. These infections can be caused by viruses, bacteria, or fungi and can affect people of all ages, with infants, young children, older adults, and individuals with underlying health conditions being particularly vulnerable. Prompt diagnosis and appropriate treatment are essential for managing respiratory infections and reducing the risk of complications.
