Some people spread pneumonia without having any symptoms of the disease; these people are referred to as carriers.

A common question people ask about pneumonia is whether it is a virus.

The answer is no.

A high fever may develop.

Symptoms by Age Group

Viral pneumonia symptoms tend to differ depending on a persons age.

Influenza is a common cause of pneumonia, particularly in those who are elderly and in kids under 2.

In most instances, influenza does not result in pneumonia.

But when it does cause pneumonia, the symptoms can be severe and deadly.

Respiratory Syncytial Virus (RSV)

RSVis an infection that commonly affects the upper respiratory system.

The infection can spread to the lower respiratory tract, causing pneumonia.

Coronavirus

Some people who get coronavirus develop severe pneumonia in both lungs.

Treatment may include a healthy diet, an increase in fluid intake, and getting plenty of rest.
