• Who is at risk this?
It’s almost impossible to avoid viruses and bacteria, but certain risk factors increase your chances of developing acute respiratory infection.
The immune systems of children and older adults are more prone to being affected by viruses. Children are especially at risk because of their constant contact with other kids who could be virus carriers. Children often don’t wash their hands regularly. They are also more likely to rub their eyes and put their fingers in their mouths, resulting in the spread of viruses.
People with heart disease or other lung problems are more likely to contract an acute respiratory infection. Anyone whose immune system might be weakened by another disease is at risk. Smokers also are at high risk and have more trouble recovering.
• How is this diagnosed?
In a respiratory exam, the doctor focuses on your breathing. They will check for fluid and inflammation in the lungs by listening for abnormal sounds in your lungs when you breathe. The doctor may peer into your nose and ears, and check your throat.
If your doctor believes the infection is in the lower respiratory tract, an X-ray or CT scan may be necessary to check the condition of the lungs.
Lung function tests have been useful as diagnostic tools. Pulse oximetry, also known as pulse ox, can check how much oxygen gets into the lungs. A doctor may also take a swab from your nose or mouth, or ask you to cough up a sample of sputum (material coughed up from the lungs) to check for the type of virus or bacteria causing the disease.
