Pneumonia

Globally, pneumonia (an infection of the lungs) kills nearly 1 million children younger than 5 years old each year. This is more than the number of deaths from any infectious disease, such as HIV infection, malaria, or tuberculosis.

In the United States, about 1 million people have to seek care in a hospital due to pneumonia each year. Unfortunately, about 50,000 people die from the disease each year in the United States. Most of the people affected by pneumonia in the United States are adults.

Vaccines and appropriate treatment (like antibiotics and antivirals) could prevent many of these deaths—globally and in the United States.
