A lingering cough, chest discomfort, or trouble breathing can be disturbing. Pneumonia is a lung infection that can cause mild to severe symptoms, sometimes starting like a common cold. Understanding how it spreads, who is at risk, and when to take action can help ease your concerns about this illness becoming severe. This self-assessment quiz will guide you through key information.

What Causes Pneumonia?

Pneumonia happens when bacteria, viruses, or fungi infect the lungs, causing inflammation. Common causes include the flu, COVID-19, and bacterial infections. It can even develop after a cold or a simple respiratory illness, making it harder for the lungs to work properly.

Can You Catch Pneumonia?

Pneumonia can spread from person to person, especially when caused by bacteria or viruses. It spreads through coughs, sneezes, or through touching contaminated surfaces. However, not everyone exposed will get pneumonia—your immune system plays a big role in how your body responds.

How Common Is Pneumonia?

Pneumonia affects millions of people worldwide each year. While anyone can get it, older adults, young children, and those with weakened immune systems are more at risk. It is a leading cause of hospital visits, especially during flu season.

When Should You Be Concerned?

Mild pneumonia may feel like a stubborn cold, but severe cases can cause high fever, chills, and difficulty breathing. If it gets worse, it can even turn life-threatening, especially for those who are at high risk. If symptoms last longer than usual or get worse, pneumonia may be the cause.
