Can an Upper Respiratory Infection Turn Into Pneumonia?

Yes, it can. When this occurs, it’s referred to as “viral pneumonia.” When you develop an upper respiratory infection, the airways within your body can become constricted and inflamed. Not only can this prevent you from properly inhaling and exhaling—and thereby clearing out mucus and secretions as intended—but it can also cause your body to produce even more mucus than it normally would. This mucus build-up serves as the ideal breeding ground for viruses and bacteria, and because upper respiratory infections also tend to weaken your immune system, you likely won’t have the ability to fight off any resulting infections. This is generally how upper respiratory infections turn into pneumonia.

Among adults, the most common cause of viral pneumonia is the influenza virus (the flu); in young children, it is respiratory syncytial virus (RSV). When compared to bacterial pneumonia (the type of pneumonia that’s caused by a bacterial infection), viral pneumonia is generally less serious and lasts for a shorter time. That said, it’s important not to downplay the severity of viral pneumonia, since some cases can be severe and potentially fatal. Viral pneumonia is especially dangerous for pregnant women and individuals with pre-existing heart or lung disease.

Other Causes of Pneumonia

Although it’s possible  for an upper respiratory infection to turn into pneumonia, that’s not the only potential cause of this illness. Pneumonia can also develop from:

Bacterial Infections

While bacterial pneumonia can sometimes occur after someone has contracted an upper respiratory infection, in other instances it can develop on its own (for example, after someone has undergone surgery). Pneumococcal pneumonia, which is caused by streptococcus pneumoniae bacteria, is the most common type of bacterial pneumonia.

Fungal Infections

Certain types of fungi—including coccidioidomycosis, cryptococcus, histoplasmosis, and pneumocystis jirovecii—can cause someone to develop pneumonia. Individuals with compromised immune systems, as well as those who experience chronic health issues, tend to be especially at risk for developing fungal pneumonia.

In-Home Treatment for Upper Respiratory Infections & Pneumonia

We stand apart from most other healthcare providers because we bring the treatment straight to you, allowing you to be seen in person by trained medical professionals without having to step foot outside your house.
