Type of Viral Pneumonia
There are many different types of viral pneumonia. For example, some of the viruses known to cause community-acquired pneumonia include:
- Influenza virus
- Parainfluenza virus
- Human metapneumovirus
- Respiratory syncytial virus (RSV)
- Severe acute respiratory syndrome (SARS)
- Herpes zoster virus.
Viruses or fungi are less likely to cause hospital-acquired pneumonia, except in people with an already weakened immune system.
Most cases of viral pneumonia are mild. With this type, symptoms typically get better in about one to three weeks without treatment. However, some cases are more serious and may require treatment in a hospital.
